13.3.6. Troubleshooting • ADF BC Migration: Each extracted XML file is processed by a number of ADF BC migrators (each target ADF BC element has its own migrator), that together create an XML structure that is the input for the actual creation (composition) of ADF BC components. This XML structure is written to the file system, in the Java source root directory, in a file named _migratedAdfbc.xml • ADF BC Composition: Based on the migrated ADF BC XML structure of each form, the entity objects, entity associations, view objects and view links, and the application modules are created. • JHeadstart Migration: Each extracted XML file is then processed by a number of JHeadstart migrators (each target JHeadstart Application Definition element has its own migrator), that together create an XML structure that is the input for the actual creation (composition) of the JHeadstart Application Definition file. This XML structure is written to the file system, in the Java source root directory, in a file named _migratedJhs.xml • JHeadstart Composition: Based on the migrated JHeadstart XML structure of each form, the JHeadstart Application Definition file is created, and stored in the properties directory of the ViewController project. If the ADF2Generator run was successful, you can safely delete the intermediate results of the Forms2AdDF Generator, being the extracted and migrated XML files in the Java source root directory. However, if processing failed with an error, these XML files can be used for troubleshooting as explained in the next section. When the JHeadstart Forms2ADF Generator fails with an error, the first thing to do is to assess which form module is causing the error. This information can easily be obtained from the log window in JDeveloper, which prints an informational message for each processing phase, for each module, as show in the screen shot below. JHeadstart Developer’s Guide Forms2ADF Generator 13 - 11
The last printed line in this window will tell you which forms module the JFG was processing when the error occurred, and in which phase of the processing. Typically, an unexpected error dialog window will be displayed, which provides more information about the error that occurred. For example, the error dialog below will be displayed when no table or view information could be queried from the Oracle data dictionary tables during the extraction phase of a form module. To solve this error, make sure that the database connection you specified has all the required privileges. See section 13.3.3 “Select Database Connection” for more information. While you can fix the above error, most other unexpected errors might be related to a problem in the JFG code base. While the JFG has been tested against numerous simple to very complex forms, it is still in preview status. It has not been proven yet in a large-scale customer project. There might be (combinations) of form element definitions in your oracle forms that cannot be handled by the JFG. Or, the JFG will run and finish successfully, but the outputs do not match your expectations based on the form definition. 13 - 12 Forms2ADF Generator JHeadstart Developer’s Guide
