I installed Oracle 10g XE and SQL Developper 2 in my PC, they works perfect. Yesterday, I upgrade to 11g r2 XE, after restar my PC, the SQL Developper 2 cannot work:
Failed to create addin oracle.dbtools.raptor.report.addin.ReportAddin
I removed all data, but cannot work as before, based on my research, I think it’s because the SQL Developper is too old.
so I download a new version of SQL Developper, and it works!
