Stored Java procedure Problems again

Hello I need help figuring out this error. Please. Its for a stored procedure executing in Oracle 8i. Any ideas would be greatly appreciated I have looked at the docs and seem to be calling it correctly. Am I missing something simple? (or am I just simple?)

Thanks for any and all help
Chris

Heres the bit of code from the java program
/***************************************************************************
****/
public String BOB(String commandToSwitch){  DMS command = new DMS(commandToSwitch);  return bigString;
}

/***************************************************************************
******/

This is the wrapper

CREATE OR REPLACE FUNCTION dms2 (command VARCHAR2) RETURN VARCHAR2 AS
LANGUAGE java
name 'DMS.BOB (java.lang.String)
  RETURN java.lang.String';

and this is the error I get

Warning: Function created with compilation errors.
