Hi Tom,

I'm getting the same error. Is there a solution for this or do I just have to wait?

hi, silvion, if you can't wait, set java command point to jdk1.6_home/bin/java.exe and try
tom will fix this and make it jdk1.5 capacitable

activiti-admin

Thanks for the feedback. I'd changed the JAVA_HOME, but forgot the addition to PATH.

Now it works fine, except the activiti-modeler, which doesn't start at all.

Kind regards,

Silvion, what do you mean by "doesn't start at all"?

Did you read that "How to ask questions the smart way" article?

activiti-admin

I mean:

The activiti-modeler.war file is placed in the tomcat/webapps folder, however when I try to go to http://localhost:8080/activiti/modeler/p/explorer I don't see the modeler and I see nothing in the logfiles.
