Unable to Create Entity Object from 10.1.3 Jdev

  Unable to Create Entity Object from 10.1.3 Jdev

While creating my first workspace on Oracle JDeveloper 10.1.3 I encountered following error

Error:
Unable to Create Entity Object from 10.1.3 Jdev(R12).The check box for the table and synonym are not enabled.

 Fix:
Add all the BC4J libraries to the project for resolving this issue.

Right click the project properties and select Business Components and press OK.This will definitely resolve the issue.Then you can create the EO without any problem.
