I am deploying an .ear to JBoss 4.0.5. The .ear contains an exploded .war and a .jar with EJBs. The exploded .ear deploys OK. However, when I deploy the zipped (i.e. unexploded) .ear I get the following exception: org.jboss.deployment.DeploymentException: Failed to find module file: aries-service.war When I unzip the .ear, it deploys again fine. Any ideas? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4045998#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
