Unknow exception !!
Hello,
When I called an LocalEJB from a SessionBean by using
ctx.lookup("macausms/PhoneCounter");
and call a method findByCountryCode(853), some unknown exception and errors display.
The SELECT statement in the exception is strange that only has 3 fields but in my ejb-jar.xml, I defined 4 fields.
And, it said can't create the instance of the primary key class.
Would you please to tell me why ?
The following is my configs in ejb-jar.xml and the exceptions:
