我在创建这个EJB时所定的Primary Key Class为java.lang.String,创建后JBuilder会自动产生远程接口，本地接口和Bean类这三个文件，其中本地接口中的Find方法为：

public RemoteInterface findByPrimaryKey(String primKey) throws ObjectNotFoundException, RemoteException, FinderException;

这样整个工程能够成功编译，但我把Find方法改成：

public RemoteInterface findByPrimaryKey(String primKey,String primKey1) throws ObjectNotFoundException, RemoteException, FinderException;
再把Bean类文件中的Find方法做相应的修改后整个工程就不能成功编译了，出现以下错误信息：

"MusicEJB.jar": F:\bea\jdk141_02\bin\javaw -classpath "E:\Objects\MusicServer\classes;F:\bea\weblogic81\server\lib\weblogic_sp.jar;F:\bea\weblogic81\server\lib\weblogic.jar;F:\bea\weblogic81\server\lib\webservices.jar;" weblogic.appc -keepgenerated -forceGeneration -compiler F:/bea/jdk141_02/bin/javac E:/Objects/MusicServer/MusicEJB.jar.jar -output E:/Objects/MusicServer/MusicEJB.jar

"MusicEJB.jar": [J2EE:160121]Errors encountered while compiling module 'E:\Objects\MusicServer\MusicEJB.jar.jar':

"MusicEJB.jar": In EJB LoginEJB, the home interface findByPrimaryKey method parameter must be the primary key type or java.lang.Object: findByPrimaryKey(java.lang.String,java.lang.String)

也就是说我的主键是一个复合键，请问这个问题改这么解决，由于我是初学者，所以请详细解答，非常感谢！！！！
