当我尝试在WAS 6.1上部署EJb 3.0 EAR时，iget：
The EAR file could be corrupt and/or incomplete. Make sure that the application is at a compatible Java 2 Platform, Enterprise Edition (J2EE) Level for WebSphere Application Server.
AppDeploymentException: [META-INF/ejb-jar.xml] org.eclipse.jst.j2ee.commonarchivecore.internal.exception.DeploymentDescriptorLoadException: META-INF/ejb-jar.xml
但这是一个EJB 3.0应用程序，为什么它要查找ejb-jar.xml？
