且看下面的代码就是我描述的情形:
比如第一个ejbCreate方法与第三个方法参数基本一样,其的第二个参数本来CustomerRemote customer,编译后成了String customerid,变成完全与第三个方法参数一样,所以出现“"OrderBean.java": Error #: 450 : duplicate definition of method ejbCreate(java.lang.String, java.lang.String, java.util.Collection) in class jasmine.OrderBean at line 255, column 16
”错误。
