When you work on larger JDeveloper/ADF 12c project, most likely you will experience issues with application redeployment (rerun). These two issues will be encountered:
1. It doesnt work anymore (it worked on 11g) to simply rerun application (applies for 12.1.3 and 12.2.1), without stopping it and then running again. In most of the cases if you try to rerun application, some strange errors are returned or changes are not visible at all. It takes time to stop application and run it from scratch
2. Oracle recommended approach is to use Make All to recompile the code and then refresh or reopen browser (Servlet Reload or Fast Swap options). This should bring the changes in ADF BC, Bindings, Task Flows and UI. While this works on simple use cases, often it doesnt work if many files are changed at once
What if you want to re-run application in JDeveloper 12c, same as it was possible in 11g? Yes, you can do it. There is a simple configuration change in JDeveloper 12c, to be able to rerun application without issues:
Go to JDeveloper preferences wizard and select Run option. Uncheck option "Enable Application Rerun Optimizations" - this will allow to rerun ADF application without errors and without a need to stop and start it manually:
Once application rerun optimizations are disabled in JDeveloper, you should add simple configuration to your ADF application (to make sure application redeploys fast). Disable auto generation for JDBC descriptors in application profile (Deployment -> WebLogic):
Provide external Data Source in AM configuration, or set direct JDBC URL (suitable for testing locally, as in my case):
Do above steps, when Make All (Servlet Reload or Fast Swap) doesn't work for you:
