Developing EGL applications
Enterprise Generation Language (EGL) is a programming language that you can use to focus on business problems instead of software technologies. Within the Rational® development environment, you can use EGL wizards and other tools to write complex applications with minimal effort.
EGL Programmer's Guide
The EGL Programmer's Guide covers using EGL within the Eclipse Integrated Development Environment (IDE), as well as some of the common programming tasks that EGL developers perform.

    The most recent EGL documentation is in the IBM Business Developer documentation.
  - EGL Programmer's Guide
    The EGL Programmer's Guide covers using EGL within the Eclipse Integrated Development Environment (IDE), as well as some of the common programming tasks that EGL developers perform.
    - Introduction
      These topics explain the fundamentals of using EGL in the Eclipse IDE, as well as changes to the EGL language and IDE in this version.
    - Contents of an EGL application
      EGL applications contain projects, packages, folders, and files.
    - Properties
      Properties set specific options for parts. In general, you specify the properties when you create the part and then the properties are static. In certain circumstances, however, it is possible to change a property dynamically.
    - Annotating EGL Applications
      EGL developers can annotate their applications to indicate the version, authors as well as a general description.
    - Import and use statements
      Use the EGL import and use statements to expand the visibility of code elements.

For details about deployment, see “Introduction to EGL generation and deployment” and “Add web-service deployment entries in the EGL deployment descriptor.”
    - Generating source code from UML models
      You can use transformations to create source code from a UML model. First you must create a transformation parameters file and then apply those parameters to a model.

        Before you can run web transactions in EGL, you must modify at least one configuration file.
      - Running VGWebTransaction programs
        To run a web transaction program, start by running EGLWebStartup.jsp on your web server.

  - Generation for VSE Feature Reference
    This reference manual provides z/VSE-specific information about developing and generating EGL programs in the VSE environment.
- Source code analysis with code review
  With code review, you can create configurations of coding rules for EGL source code. You can then run the configurations to check the source code for consistency with the rules.
- Responsive Design Support in IBD
  What is Responsive Design? Responsive design is an approach for creation of web pages that automatically scales its content and elements to match the screen size on which it is viewed. So, instead of designing multiple websites for different devices with variable screen sizes, we can design just one website that scales up or down automatically, to match the device it’s being viewed on.

Adding web transaction support to an EGL web project

Before you can use web transactions in your EGL project, you must add support for web transactions to your project. You can do this when you create the project, or add support to an existing project.

Add support for web transactions at the time you create a project:

Create a new EGL web project and select the Show Advanced Settings check box on the general settings page of the New EGL Project wizard.
Select the EGL support with Legacy Web Transactions check box on the Project Facets page. The Project Facets page is the second page after the general settings page.

Add support for web transactions to an existing EGL web project:

In the Project Explorer view, right-click the EGL web project and then click Properties. The Properties window opens.
In the Properties window, click Project Facets.
Click Add/Remove Project Facets.
In the Project Facets window, select the EGL support with Legacy Web Transaction check box.
Click Finish.
Click OK.

Adding support for web transactions makes the following changes to the project:

Jar files are added to the folder WebContent\WEB_INF\lib and to the project's Java™ build path. These Jar files constitute the runtime support of a web application and the EGL gateway servlet.
The following sample and utility files are added to the project's WebContent folder:
- CSOERRORUIR.jsp
- EGLWebStartup.jsp
- Vagen1EntryPage.jsp
- Vagen1ErrorPage.jsp
- Vagen1ExpiredPasswordPage.jsp
- Vagen1LogonPage.jsp
- vawcg-wp.gif
- visage.gif
Files that set properties for the gateway servlet and information for linkage between web transactions are added to the folder JavaResources\JavaSource. See Gateway servlet parameters and Linkage properties.
The gateway servlet is registered in the web configuration file.

You can not remove support for web transactions from a project.

If you want each new EGL web project created to have support for web transactions, open the EGL preferences window and select the EGL support with Legacy Web Transactions check box. See Setting EGL preferences.
