Hi, can you help me about this problem?? I'm trying to deploy a seam application(using also jsf with icefaces) on jboss 4.0.5 GA with EJB3-Clustered configuration. I think that the deploy goes fine but when I try to access to index of my application, I see this error: 11:00:58,768 ERROR [STDERR] 07-Feb-2007 11:00:58 com.sun.facelets.compiler.TagLibraryConfig
