Hi,
Sorry that you are seeing issues with MyEclipse 2015 CI 11. I could not replicate the issue with JPA reverse engineering at my end on CI 11.
I checked with a Professional license and I see the JAX-RS support included.
Can you please give us some more details?
1. Can you please go through the JPA tutorial here and check if you see the issue with a new project to rule out project specific issues? : https://www.genuitec.com/products/myeclipse/learning-center/persistence/myeclipse-jpa-tutorial/
Switch to a new workspace and follow the tutorial.
2. If you are still seeing issues, please send us the screenshots of the issue you are seeing to help us get a visual. If possible please share with us the project along with the database details.Also attach the .log file which is located at <workspace dir>/.metadata/.log.
3. Please share the MyEclipse Build Id from Help > About section. Also ‘pm’ me your license details to help us investigate further.
