Hello: I am using JBoss 4.2.2 along with the OpenSAML toolkit. Each of these uses a different version of xerces and xalan. The ones that come with OpenSAML seem to be newer (2.9.1 and 2.7.1 respectively). However, when I replace the jboss supplied version with these new jars CMP seems to stop working. Is there any way that I can upgrade these libraries for xerces and xalan without breaking other features in jossb. thanks for your help. suneet View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4162219#...
