My weblogic 7 can not run stateful session bean??

Question

Hi,all
I create a stateful session bean in jbuilder 7 and deploy it to weblogic 7,it
successed.The Home interface have a method like this:
public TestRemote create(int var) throws RemoteException, CreateException;
But the client test bean call the create(int var) method throwing
a exception :
java.lang.IllegalArgumentException: wrong number of arguments
Start server side stack trace:

Then I deploy it to the borland application server 4.5,it did work!!
Somebody can help me ?thx
