java.lang.AbstractMethodError: bank._BankMgr_Stub.updateBalance(ID)V

--------------------------------------------------------------------------------

Hi,
I am using sun one studio IDE and Sun one app server.

While I was running test client here is what I am getting:

java.lang.AbstractMethodError: bank._BankMgr_Stub.updateBalance(ID)V
at bank.BankMgrTest.main(BankMgrTest.java:31)
Exception in thread "main"

I am really frastruated and I have no idea why is it throwing an abstract method exception when I am not invoking any abstract method. I would really appreciate any help on this.

Can someone can help me please?
I have no clue as why is it throwing this exception.
