[Isis-users] JISIS error on Linux

[Leandro Vicente]

Mr. Dauphin


I've got a problem with JISIS and I would appreciate some help. I'm using Ubuntu 10.04 and my Java installation is



java version "1.6.0_22"

Java(TM) SE Runtime Environment (build 1.6.0_22-b04)

Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)



The permissions settings are fine, but even running jisis_suite with sudo, when I try to open a connection (default local host, default settings) I've got this error message: A java.lang.NullPointerException exception has occurred.



Do you have any tip of what may be going wrong?

The error log is:
