JP7193877B2 - Web server and application operation system using the web server - Google Patents

Description

The present invention relates to a technology for webizing a client-server type application operating system in which a client terminal and a server terminal are connected to a local area network.

Patent Document 1 is known as a client-server type application operating system in which a client terminal and a server terminal are connected to a local area network. This conventional application operating system has a server terminal and one or more client terminals, which are connected to a local area network.

A business application is installed in the server terminal. Business applications are software for performing various management tasks such as sales/sales management, inventory management, and order management, and are built using a program language (for example, RPG language) that excels in data input processing. A screen display application unique to the operating system is installed in the client terminal to display the operation screen of the business application.

In the prior art, when a user inputs necessary information from an input device of a client terminal, the input information is sent from the client terminal to the server terminal via the local area network and arithmetically processed in the business application of the server terminal. The calculation result is sent from the server terminal to the client terminal via the local area network. The dedicated screen display software installed in the client terminal analyzes the information of the calculation result and displays the next operation screen (along with the calculation result in some cases) on the display screen.

Japanese Patent Application Laid-Open No. 2011-28406 (Fig. 1)

In recent years, a work style called "telework" has been promoted, in which a terminal used at home is used to access a personal computer at work via the Internet for work. Against this background, I would like the conventional application operation system, in which the server terminal and the client terminal are connected to a local area network, to be telework-compatible (in other words, the terminal used at home can be connected to the workplace via the Internet). We have received requests from users that they would like to be able to access the server terminal of

As a method for teleworking a client-server type application operation system in which a client terminal and a server terminal are connected to a local area network like the conventional technology, there are two methods called "internetization" and "webification". can be considered.

"Internetization" is a method of installing a device called a "web server" that serves as a window for accessing server terminals from the Internet network, and can be realized by connecting this to the server terminal.

According to this "internetization", it is possible to support telework simply by introducing a web server, and there is almost no need to modify business applications or screen display applications (even if there is, it can be handled with minor modifications). While there are merits, there is a problem that it is difficult to support multiple devices, which will be described later.

In other words, it is necessary to install a dedicated screen display application corresponding to the business application on the client terminal to display the calculation results sent from the server machine on the display screen. , There are various types of terminals used at home, such as desktop computers, notebook computers, and tablet terminals, and the operating systems used in each terminal also vary (in other words, each terminal use environment is very different).

Therefore, developers of application operation systems are required to develop screen display applications (multi-device compatibility) suitable for each usage environment of each client terminal, but such multi-device compatibility is difficult. requires a lot of effort and cost. In addition, when it becomes necessary to modify the program of the screen display application, it is necessary to modify all the screen display applications developed for each usage environment, and it is very difficult to deal with it.

On the other hand, "webification" is the same as "Internetization" in that a web server is installed, but a general-purpose web browser such as Google Chrome (registered trademark) or Safari (registered trademark) installed in the client terminal can be used as the system. It can be realized by using it instead of a dedicated screen display application.

According to such a "webification" method, a general-purpose web browser application can be used as an application for displaying the operation screen of a business application on a client terminal. In order to display the operation screen of the business application of the system on the web browser application, it is necessary to make large-scale modifications to the business application.

However, in order to make modifications for such webization, the business application program must be programmed in a web development language such as Java, Ruby, or PHP. On the other hand, business applications are programmed in non-web development languages because of their usability and operability. There was a problem that it was not possible to "webize" business applications.

The present invention has been made in view of such conventional problems, and easily realizes web conversion and multi-device conversion for server terminals in which business applications programmed in non-web development languages are installed. To provide a web-enabled server and an application operating system using the web-enabled server.

The invention described in claim 1 is "used by connecting to an application server 12 in which a business application A programmed in a non-web development language is installed, and a web browser application W installed in a client terminal 16. A web server 14 for an application operation system 10 that displays an operation screen of a business application A on the web browser application W by exchanging information between them via the Internet network 18,

" A webification server 14 for the operational system 10 .

The invention described in claim 2 is "an application server 12 in which a business application A programmed in a non-web development language is installed,

The display request messages T and Ti and the display response messages T' are character information whose display contents displayed on the operation screen of the business application A are defined by the type information, the position information, and the individual information. " An operating system 10 is shown.

In these inventions, the display request message and the display response message used for arithmetic processing of the business application are defined by the type information, the position information, and the individual information. Since it is composed of character information that has been written, it can be handled in common by both a business application programmed in a non-web development language and a conversion application programmed in a general processing language. Then, the conversion application converts this common information into information that can be read by the web browser application of the client terminal (display response, which is a character string in HTML format), so that the web browser application W of the client terminal can execute the business application A operation screen can be displayed (in other words, web and multi-device implementation can be realized).

In addition, since the display position of each display content displayed on the operation screen is specified by the position information, it is possible to display the operation screen of the business application in the same layout for the web browser applications of all client terminals. becomes possible.

The communication application C2 returns corresponding screen information (display response S') when a display request S for an operation screen (web page) of the business application A is received from a web browser application W of the client terminal 16, which will be described later. It functions as a "web server".

The conversion application B converts the information (display request S) received from the communication application C2 into message format information (display request message T) used by the business application A, and converts the message format information (display request message T) to the business application A of the application server 12, and receives processing result information (display response message T') processed in the business application A in the message format, converts it into HTML format text information, and converts it into HTML format text information. It is software having a function to return to the client terminal 16.

The web server communication device 38 is hardware provided for transmitting and receiving information between the application server 12 and the Internet network 18, and the communication application C2 and the conversion application B described above can be used to communicate with the application server 12 and the client. Information (display request S, display response S', display request message T, display response message T') is exchanged with the terminal 16. FIG.

The client terminal 16 is used as an operating terminal for operating the business application A installed in the application server 12 . Specific examples of the client terminal 16 include a notebook computer 16a and a tablet terminal 16b.

The basic design of the client terminal 16 is similar to that of the application server 12 and web server 14, and as shown in FIG. A storage device 44 , a client terminal communication device 46 and an input/output device 48 are provided.

The client terminal central processing unit 40 governs the overall operation of the client terminal 16, and sequentially reads programs (instruction sequences) temporarily stored in the client terminal main memory 42, which will be described later, and interprets and executes them. Information is processed.

Similarly, information is processed by sequentially reading, interpreting, and executing a sequence of instructions called a program temporarily stored in the client terminal main storage device 42, which will be described later.

The web browser application W is general-purpose software for displaying web pages, and accesses a web server on the Internet network 18 (this corresponds to the communication application C2 of the web server 14 in this embodiment) to display web pages. It has a function of acquiring information (display response S′) for displaying , and appropriately arranging and drawing characters and images according to the acquired information. As an example of the web browser application W, for example, Google Chrome (registered trademark), Safari (registered trademark), etc. are known.

The client terminal communication device 46 is hardware provided for transmitting and receiving information to and from the web server 14 via the Internet network 18 . , information (display request S, display response S') is exchanged.

The input/output device 48 is hardware for inputting information (characters, numbers, etc.) necessary for operating the business application A and for displaying the operation screen of the business application A. The display monitor 48a and the input device 48b. When the client terminal 16 is a notebook computer 16a, the external keyboard corresponds to the input device 48b, and when the client terminal 16 is the tablet terminal 16b, the software keyboard displayed on the display monitor 48a corresponds to the input device 48b.

A method of operating the business application A installed in the application server 12 from the client terminal 16 using the application operating system 10 configured as described above will be described. First, a method of displaying the operation screen (initial screen) of the business application A on the display monitor 48a of the client terminal 16 (here, the notebook computer 16a is taken as an example) will be explained. I will explain how to operate it.

[Display of initial screen of business application A]
The power of the client terminal 16 (laptop computer 16a) is turned on to make it ready for use, and the web browser application W is started. When the web browser application W is activated, the operation screen 56 of the web browser application W is displayed on the display monitor 48a of the client terminal 16 (see FIG. 5).

An operation screen 56 of the web browser application W has an address bar 56a, an update button 56b, etc. at the top of the screen (these are provided in common regardless of the type of web browser application W). A URL for accessing the business application A is entered in the address bar 56a as a domain name (http://abc.co.jp/SMP00 in this embodiment), and the update button 56b is clicked.

When the update button 56b is clicked, the web browser application W manages the corresponding domain based on the domain name entered in the address bar 56a ("abc.co.jp" corresponds here). A web server (here, the communication application C2 of the web server 14) is searched from the Internet network 18 and accessed, and page information (screen information) of the operation screen of the business application A is sent to the communication application C2 as the web server. demand. When the business application A is first started, information of the initial screen of the program SMP00 of the business application A is requested as screen information.

In this specification, the web browser application W's request for screen information to the communication application C2 is called a "display request S".

When the communication application C2 receives the "display request S" from the web browser application W, this "display request S" is transmitted to the conversion application B as it is.

In the conversion application B, the "display request S" received from the communication application C2 is converted into a "display request message T", and the converted "display request message T" is sent to the business application A via the communication application C1 of the application server 12. sent to

Here, the “display request message T” is the “display request S” described in accordance with the message format used by the application server 12 .

When the business application A of the application server 12 receives the "display request message T" from the conversion application B, the screen information of the operation screen corresponding to the "display request message T" is displayed as the "display response message T'" on the web conversion server 14. is returned to the conversion application B of . Here, the screen information of the initial screen of the program SMP00 of the business application A is returned to the conversion application B of the web server 14 as "display response message T'".

Here, the "display response message T'" will be further explained. (text data).

For example, when three objects (object 1 to object 3) are displayed on the operation screen of business application A, the "display response message T'" contains "character string of object 1, character string of object 2, Character string of object 3", each object described by a character string conforming to the electronic message format used in the application server 12 is written together in one line.

Each object is, for example, divided into three items of "type information", "position information", and "individual information" as shown in FIG. 6, and each item is further divided into elements and defined. Each element is represented by half-width alphanumeric characters, full-width characters, or symbols, and a delimiter is inserted between the elements. This causes each object to be described as a string.

Each item and its elements will be explained. "Type information" is an item that defines the type of display content (object). '01' for a field, '02' for a 'button' that triggers a given action, and '03' for a 'checkbox' used to select multiple items from several options. ', '04' for a 'radio button' used to select one item from several options, and '05' for a 'label' that displays information about what is displayed on the screen. Thus, a unique number assigned to each type is defined as an element.

"Position information" is an item that defines the position and size of an object to be displayed on the operation screen, and the position and size of the object. height) is defined as an element.

"Individual information" is an item that defines specific information of display content (object), and here (serial number, ID, field, number of digits, format) are defined as elements. Briefly explaining each element, the "serial number" is a serial number given to each object, and the "ID" is used to identify the target object from among the multiple objects displayed on the operation screen. This is the assigned identifier. "Field" specifies the type of characters (text) entered in the object. For example, "1" indicates that only half-width numbers can be entered, and Types of characters that can be input to each object are defined as elements, such as "2" and "3" if double-byte characters can be input. "Number of digits" defines the number of characters of an object that can be entered. "Format" is for defining the appearance of the input object, and in this embodiment, (character font, character size, character typeface, character shaping) are defined as elements. As for the typeface of characters, a unique number for each typeface is defined as an element, for example, "1" for bold and "2" for italic. For character formatting, a unique number for each formatting is specified as an element, for example, "1" for left-aligned display, "2" for centered display, and "3" for right-aligned display. ing.

The order of description of each item (type information, location information, individual information) that constitutes the display response message T' conforms to the specifications of business application A (the order of reading is determined in business application A). . In this embodiment, "type information", "position information", and "individual information" are arranged in this order. If the program is programmed to read and process "location information" in this order, the display response message T' will also be described in the order of "individual information", "type information", and "location information" according to the specifications.

As the "delimiter" that separates the elements, any commonly used delimiter such as a comma or space can be selected. (Commas and spaces may be used as elements, in which case there is a problem that it is not possible to determine whether the commas or spaces in the display response message T' are delimiters or elements.) .

Based on the above, in FIG. 6, an input field with a width of 100 and a height of 20 is displayed at a position of 60 from the left and 10 from the top. Display the specified input information in gothic, italic, left-justified format" is described in the message format of the application server 12 .

Then, all the objects displayed on the operation screen of the business application A are sequentially converted into character strings in the same manner as described above, and these are combined into one line of character strings as "display response message T'". , will be sent to conversion application B on webification server 14 .

When the conversion application B of the web server 14 receives the "display response telegram T'", the conversion application B automatically converts these into HTML format character strings and summarizes them into one line of character strings. Then, this one-line HTML-format character string is returned to the web browser application W of the client terminal 16 as a "display request Si".

HTML is a general-purpose programming language used to display web pages, and as shown in FIG. The operation screen of the web page is defined according to the rule of enclosing with ">").

That is, in the conversion application B, the display content (display response telegram T') expressed in alphanumeric characters is converted into a character string in HTML format bounded by tags, and this is converted into a "display response S'" by the web browser application W. will be returned to In FIG. 7, line feeds are provided between tags and displayed in multiple lines for convenience of explanation. is described as

The web browser application W of the client terminal 16 interprets the content of the HTML character string "display response S'" received from the conversion application B, and displays it on the display monitor 48a according to the content (see FIG. 8). As a result, the operation screen (initial screen) 58 of the business application A is displayed on the display monitor 48a of the client terminal 16 (laptop computer 16a) (FIG. 8).

A first entry field 60, a second entry field 62, and an enter button 64 are displayed on the operation screen (initial screen) 58 of the business application A (program SMP00) shown in FIG. The left side of the first entry field 60 is labeled "company name", and the left side of the second entry field 62 is labeled "TEL".

[Information input and its processing]
Next, a procedure for inputting various types of information to the operation screen (initial screen) 58 of the business application A will be described.

A company name (“Iroha Co., Ltd.” in FIG. 9) is entered by the user in the first entry field 60, and a telephone number (“012-345-6789” in FIG. 9) is entered in the second entry field 62. is input, and finally the registration button 64 is clicked.

Then, the web browser application W sends a "display request S" requesting display of the next operation screen to the web server (communication application C2) of the web server 14, as described above. The difference from the case of requesting the initial screen described above is that information input by the user (information input in the input fields 60 and 62) is added to the "display request S". The "display request S" including the user's input information is referred to as "display request Si". A specific example of the "display request Si" including the input information is as shown in FIG. 10, for example.

Briefly describing the contents of FIG. ) indicates that the information that "012-345-6789" was input is added.

The “display request Si” is sent from the client terminal 16 to the conversion application B of the web server 14 via the Internet network 18 as described above.

Upon receiving the display request Si, the conversion application B converts it into a display request message Ti and sends the display request message Ti to the application server 12 .

In the application server 12 that has received the display request message Ti, the business application A executes processing based on the input information added to the display request message Ti, and the screen information of the operation screen after processing is used as a display response message T'. Respond to conversion application B.

As described above, the conversion application B automatically converts the display response message T' into an HTML document, and returns the converted HTML character string to the web browser application W of the client terminal 16 as a "display response S'". As a result, the operation screen after processing (here, the new operation screen 58 shown in FIG. 8) is displayed on the display monitor 48a of the client terminal 16 (16a).

Then, the user performs the following information input work, and a "display request Si" including the input information is sent from the client terminal 16 to the web server 14, and the web server 14 sends a "display request message Ti" including the input information. and processed by the application server 12, the processed screen information is returned to the web conversion server 14 as a "display response message T'", and the web conversion server 14 converts HTML into "display The response is converted into a response S′”, and the operation of displaying a new operation screen on the display monitor 48a of the client terminal 16 is repeated.

As described above, according to the application operating system 10 of the present embodiment, simply by installing the web server 14, the application server A in which the business application A programmed in a non-web development language is introduced can be web-based. Both multi-device can be realized.

The display position of each display content (object) displayed on the operation screen is defined by the position information. can be displayed in the same layout.
