[jboss-user] [EJB 3.0] - Error with EJB3 application deployment

Hi All I have been trying to deploy one of my application that works perfect on JBOSS 4.0.5 while on JBOSS 4.2.0 GA version it is not deployed with the ROOT CAUSE being as shown below... What I was keen to understand is what the error " Reason: java.lang.NoClassDefFoundError: org.hibernate.cfg.EJB3DTDEntityResolver" signifies. 2007-08-10 01:09:37,667 ERROR [org.jboss.deployment.scanner.URLDeploymentScanner] Incomplete Deployment listing: --- Incompletely deployed packages --- org.jboss.deployment.DeploymentInfo@75ca39c6 { url=file:/data/jboss-4.2.0.GA/server/default/deploy/mail-service.xml } deployer: org.jboss.deployment.SARDeployer@72897289 status: null state: FAILED watch: file:/data/jboss-4.2.0.GA/server/default/deploy/mail-service.xml altDD: null lastDeployed: 1186688239196 lastModified: 1186688239000 mbeans: org.jboss.deployment.DeploymentInfo@229581fd { url=file:/data/jboss-4.2.0.GA/server/default/deploy/compliancetracker.ear } deployer: org.jboss.deployment.EARDeployer@bef0bef status: null state: FAILED watch: file:/data/jboss-4.2.0.GA/server/default/deploy/compliancetracker.ear altDD: null lastDeployed: 1186688243682 lastModified: 1186688243000 mbeans: --- MBeans waiting for other MBeans --- ObjectName: jboss.j2ee:service=EJB3,module=compliancetrackerEjb.jar State: FAILED Reason: java.lang.NoClassDefFoundError: org.hibernate.cfg.EJB3DTDEntityResolver --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: jboss.j2ee:service=EJB3,module=compliancetrackerEjb.jar State: FAILED Reason: java.lang.NoClassDefFoundError: org.hibernate.cfg.EJB3DTDEntityResolver View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4072815#...
