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 Generation Guide
The EGL Generation Guide covers the process of converting EGL code to Java™ or COBOL source code, including the processes and the files involved. This section is intended for a developer who will generate or deploy EGL applications.

Developing
- Model driven development of EGL code
- 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.
- Generating the EGL Dependency Graph from EGL projects
- Generating Source Code from OpenAPI Documents
- Developing EGL applications

  - Additional information about EGL
    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.
  - EGL Generation Guide
    The EGL Generation Guide covers the process of converting EGL code to Java™ or COBOL source code, including the processes and the files involved. This section is intended for a developer who will generate or deploy EGL applications.
    - Introduction to EGL generation and deployment
      After you write and test EGL source code, you generate Java™, JavaScript™, or COBOL code for a target platform.
    - Generation using the Eclipse workbench
    - Generation using the EGL software development kit (SDK)
    - Generating from the workbench batch interface
      The workbench batch interface is a feature that lets you generate and deploy EGL output from a batch environment that can access the workbench.
    - Generating with an Ant script
      You might create an Ant script that cleans a workspace and causes an automatic build and generation. To help you save processing time, the product provides a Java™ VM argument to include in the Ant script.
    - Creating headless EGL build
      You can have multiple Ant tasks for a headless build. With headless builds, EGL builds can be managed more efficiently and EGL can support Agile programming better.
    - Ant tasks for headless build
      Ant tasks are required to create an Ant script that is to be used in a headless EGL build. Besides the Ant tasks defined by Eclipse, Rational® Application Developer, and the ant-contrib library, IBM Business Developer also provide several Ant tasks for your use.
    - EGL Generation Results view
    - Writing Java™ code to capture details of code generation
      You can now write Java™ code to produce a report or otherwise respond to events at generation time.
    - Creating and maintaining a build file
    - Build Descriptor part
      A build file (.eglbld extension) can contain multiple Build Descriptor parts. Each Build Descriptor part controls the generation process for a particular set of circumstances.

    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.

destPort

The destPort build descriptor option specifies the port on which a remote build server is listening for build requests.

This option is meaningful if one of the following situations applies to you:

You are generating COBOL code;
You are generating Java™ code to a directory rather than a project (by setting a value for the destDirectory build descriptor option), and you specify a value for the destHost build descriptor option.

No default value is available.
