Exception occured in J2EEC Phase
com.sun.enterprise.deployment.backend.IASDeploymentException: 
Exception Description: Missing meta data for class [java.lang.Integer]. Ensure the class is not being excluded from your persistence unit by a <exclude-unlisted-classes>true</exclude-unlisted-classes> setting. If this is the case, you will need to include the class directly by adding a <class>[java.lang.Integer]</class> entry for your persistence-unit.
