EAS open data file issue

Hi,

On Essbase/EAS 11.1.1.3 and Weblogic 9.3MP3, when working on a rule file and opening a data file nothing happens.
The rule file was originally copied from 11.1.1.1.

We restarted EAS service without success.
We're accessing EAS through jnlp, same issue from installed console
Btw I'm using jre 1.6.0.10-b33

No log is generated when I click on "Open Data File"

Any idea or workaround? I already searched the knowledge base without success.

Thanks
