[jboss-user] problem using java xsl api in jboss 4.2.2 GA

Hello, I've got a java class which use api (javax.xml.transform.Transformer)to do xsl transformation. I tested it in a local project eclipse and it worked well. I tried to crate a webapp project with a servlet>. This webapp is packaged to a WAR file which is deployed on JBoss 4.2.2 GA. The problem is that the xml result on jboss is different than the one I have when I execute locally my class. I've namespace problem on the JBoss's execution. I try to change the parameter UseNamespaceAwareParser in org.jboss.deployment.SARDeployer-xmbean.xml, but it changes nothing. The two projects use the same java version. Do you have an idea, on the problem? Thanks :-)
