Hi all, I have developed a very small session bean which has a function and will return a string. i am using ant 1.6.5 for building the .ear file I successfully made the ear and deployed it over JBoss 3.2.5 and it deployed successfully And when i tried to deploy the same ear in JBoss 4.0.2 it has shown me error at the deployment time itself. Here is the Log File [org.jboss.deployment.scanner.URLDeploymentScanner] Watch URL for: file:/E:/dinesh/jboss-4.0.2/server/default/deploy/Test.ear ->
