Error running project in JDeveloper - "java.sql.SQLDataException: ORA-01882: timezone region not found"

This error is not related to system time.

Fix: heres what I did,

In  Jdeveloper, 

Will need to modify settings below two places.

1) Applications -> Default Project Properties

2) Application -> Project projecties

Run/DEBUG/PROFILE -> select Default, click edit


add  -Duser.timezone=GMT  (Under Java Options)



This Solves the Problem !!
