I have this entity bean, MEMBER. I have created a findByName that passes in a memberId (primary key). memberId is a CMP. the return type is a collection so i can create a DTO/Facade. My
ejb ql statement looks like this:
SELECT OBJECT(m) FROM Member m WHERE m.memberId = ?1
I have a testClient with this code in the main.
MemberTestClient1 client = new MemberTestClient1();
try {
Integer memberId = new Integer("1");
Collection c = client.findByName(memberId);
Iterator i = c.iterator();
while (i.hasNext()) {
MemberRemote mcr = (MemberRemote)PortableRemoteObject.narrow(i.next(),MemberRemote.class);
System.out.println("member first name = " + mcr.getFName());
System.out.println("member last name = " +mcr.getLName());
}
} catch (Exception ex) {
ex.getStackTrace();
System.out.println("Exception = " + ex);
I can not see anything wrong with the ejb ql statement. I have looked over the ejb-jar.xml and the ejb-borland.xml for anything that looks out of place - found nothing. I add another entity bean and make code corrections so two entity beans are used during the DTO/facade. The error is the same - it does not seem to like Member???
Help ... Any ideas???
The error I receive is:
