请大家帮忙看看这个错误
"ejb2.ejbgrpx": ERROR: Error from ejbc: For cmp-field 'entityContext' of bean 'Enterprise1', we expected to find a corresponding 'getEntityContext' method in the abstract bean class. Compilation cannot continue without this 'get' method
"ejb2.ejbgrpx": ERROR: ejbc found errors
这个一个CMP的EJB,在编译时出现上面这个错误,请问是什么原因,要如何解决?谢谢大家。
