You are right but i'm student working on a thesis project, i'm not working for a company.
Btw now i enabled debug logs.
Maybe i'll found the problem.
I have another strange question.
I create war files whit this command:
ant make_liferay_admin_portlet_war -Djbossliferay=true -DLR605=true -DnoAXIS=true
In this way i don't have web service access, right?
So how can communicate Liferay and Konakart?
