Hi all ,
I am using jboss2.1 , jdk1.3 and Postgresql7.0.1.
I have code below :
Staff staff = staffhome.findByPrimaryKey(new StaffPK(staffid));
staff.remove();
When i execute the code , it gave me the error message :
TRANSACTION ROLLBACK EXCEPTION: Load failed : nested exception is java.lang.IllegalArgumentException: object is not an instance of declaring class.......
I have searching the forum ...but found no any solution.
It also gave error message in jBoss version 2.2
Anybody have any ideas ???
Thanks.
