Re: [birt-dev] BIRT + JSF + HIbernate
|
I solve the problem but I don't like the solution. Perhaps because I don't
know why this solve the problem.
Looking for anything that could help my in google I found something related
with my error but in jboss enviroment. The solution for this problem was to
copy some libraries to jboss common lib directory.
I use this to try to solve my problem and I have copied all BIRT
dependecnies to lib\apps\ in JOnAS base server directory. Now it works!
But my question is: ¿Why I have to copy there this jars? ¿Why if I don´t use
hibernate, faces and BIRT in the same WAR the reports are showed with no
problems?
Still waiting for response.
Thanks.
