java.lang.RuntimeException: <0.9.7-incubating fatal user error> 异常的处理

Question

在配置roller4.0.1时，报openJPA的异常，文件用jar包时，不会出错，当用源代码时就包这个异常，这是什么原因？？

严重: Exception sending context initialized event to listener instance of class org.apache.roller.weblogger.ui.core.RollerContext
java.lang.RuntimeException: org.apache.openjpa.persistence.ArgumentException: The type "class org.apache.roller.weblogger.pojos.TaskLock" has not been enhanced.

The type "class org.apache.roller.weblogger.pojos.TaskLock" has not been enhanced.

记得JPA里面有个叫enhance的操作，好像主要是提高速度的。但是不enhance不应该报错，应该报警告的。。。
enhance具体操作没有细究，以前用netbeans做的，部署的时候netbeans会自动enhance~~~

你找找jpa文档，看看怎么enhance.做一下enhance操作试试 :。。
