We are using JBoss AS 4.0.0 with embedded Tomcat 5.0. We've used JBoss for quite a while, haven't had any problems, and now we are adding WS component which we downloaded from your site. Here is the exact file description: jbossws-1.0.4.GA; Binaries, Docs, Samples; 12 MB; 11/15/06; LGPL I followed the installation instructions, i.e. 1. Extracted jbossws.sar to the newly created directory jbossws.sar under C:\jboss-4.0.0\server\jist\deploy 3. Copied jbossws-client.jar to C:\jboss-4.0.0\client 4. Downloaded jboss-xml-binding.jar file from http://repository.jboss.com/jboss/jbossxb/1.0.0.CR7/lib/ 5. Copied jboss-xml-binding.jar file to C:\jboss-4.0.0\client and C:\jboss-4.0.0\lib Upon completion of these steps, I started JBoss and encountered org.jboss.deployment.DeploymentException: Unexpected error during load of: org.jboss.ws.integration.jboss.WebServiceClientDeployer View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3986930#...
