[NOTE: EGL Web projects and EGL Portlet projects require that runtime Java code be located in the /src directory, so it is not possible to generate code into the EGLGen folder.]
[NOTE: Only new EGL projects created in RBD 8 are configured to use the EGLGen folder for generated code. Projects that were created in other versions of RBD will continue to generate code into the same location that was used when the project was created.]
Default Build Descriptors
In addition to providing options for additional default build descriptors, the default build descriptor property page has also been updated to show which default build descriptors will be used for a selected resource, even if a default value has only been specified for a parent resource. With this change, it is much easier to determine which default build descriptor will be used for a resource, instead of needing to open the default build descriptor property page for one or more parent resources in the current hierarchy until a value is found.
Generate after Build Preference
As a result of the changes to the generation directories and default build descriptor options in RBD 8, the ‘Generate on Save’ preference options have also been updated. In RBD 7, the ‘Generate on Save’ preference allowed a user to configure which part types were generated automatically when they were built. While this was useful, it tended to result in compile errors in the generated code, since some parts would be generated automatically and others needed to be generated manually. In RBD 8, the ‘Generate on Save’ preference has been renamed to the more appropriate ‘Generate after Build’, and the preference is now used to specify what target languages should be generated after a build, instead of what part types should be generated after a build. If a target language is selected for automatic generation, any part that has a default build descriptor option specified for the selected language will be generated after it is built, which will result in all parts being generated for a particular application as it is developed.
In RBD 7, the ‘Generate on Save’ option was used to make sure that specific parts were generated before they were debugged, since the debugger executes the generated version of the source for these parts (e.g. Rich UI). In RBD 8, the EGL Advanced Builder will now generate the debug version of any part when it is built, regardless of the ‘Generate after Build’ preference settings, if a generated version of the part is required by the debugger. This change means that any EGL application can be debugged without ever invoking a manual generation, assuming the workspace Auto Build option is enabled.
[Hint: The Debug version of an EGL part can be regenerated by rebuilding the file that contains the part, or by rebuilding the project that contains the part.]
Finally, in RBD 8011, an additional option was added to the ‘Generate after Build’ preferences to control whether or not the EGL Deployment Descriptor (EGLDD file) should be generated for a particular target language (i.e. Java or COBOL). This option is enabled by default for Java, and is disabled by default for COBOL.
In this blog entry I have covered some of the more significant EGL code generation changes in RBD 8. If you have any questions or comments about these changes, or if you would like more information about any of the other code generation changes in RBD 8, you can post them in a comment to this entry.
