I've upgraded 3.8.2 to 3.8.3

I couldn't preview my reports because the JNDI connections weren't defined.
When I tried to preview my reports in back in the old PRD 3.8.2 it's work.

the file. pentaho was reloaded when I installed the new version. I add my connections in the file simple-jndi/default.proprerties. This does not work. do you have any solutions?
