[rules-users] RPC call exception with drools guvnor

[Dominik Hüttner]

Hi, 

I use drools guvnor first version 5.1.0, but now I have to use 5.0.1. 

On the PC, it has to work on, the following error is produced, when I enter
the drools webpage:

That computer has Windows XP Prof SP3, Tomcat 6.0.20, Java jdk 6.0 update
17. The same error occurs with the jboss standalone. Version 5.1.0 works
fine.

On another computer, that is configured nearly the same (WinXP prof SP3,
Tomcat 6.0.20, java jdk 6.0 update 7) all works fine.

Maybe someone can even give me an advise, what could be the problem, or
maybe have a solution.

 

Kind regards,

 

Dominik
