websphere 8 在war包安装时报错，如何解决？

ErrorThe EAR file could be corrupt and/or incomplete. Make sure that the application is at a compatible Java(TM) Platform, Enterprise Edition (Java EE) level for the current version of WebSphere(R) Application Server.

报这个错，但jar包中也没有EAR文件，jar中也没有错误，什么原因？jar包用的jdk版本和websphere是一样的
