JDeveloper: ORA-01882: timezone region found found

When trying to deploy your web application using JDeveloper to the integrated WebLogic, if you get the following error:

(oracle.jbo.JboException) JBO-29000: Unexpected exception java.sql.SQLDataException, msg=ORA-01882: timezone region not found

then to resolve this issue,

1. Goto Application menu and select Project Properties

2. In the Project Properties window, On the left pane, select Run/Debug/Profile

3. On the right pane, Edit the Default configuration (or double click on Default)

4. In the Edit run configuration window, select Launch Settings

5. For 'Java option' text box, add -Duser.timezone="+04:00"

You will probably need to save and restart JDeveloper for the changes to take effect.
