I have found the solution. Let me explaning it. The client classpath had the most obvious jar. all of them from the jboss client directory, jnp, jbosmq-client, etc ... but it is not obvious to put the regexp jar, which is in the jboss lib jar.
I had to debug my client code against the jboss mq source to note that the class RegExp uses gnu.regexp.RE. The problem is that the constructor throws a exception (no classdeffound) that is catched by asynchDeliver from the conection class and hidden to me since i have not configured log4j in the client side. Thanks for all and i think jboss is the best app server since let me debug it :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3906983#3906983 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3906983 ------------------------------------------------------- SF.Net email is sponsored by: Tame your development challenges with Apache's Geronimo App Server.
