I'm using jboss 2.1 (binary bundled with tomcat).
I'm having a problem with CMP finders that return Collections. The first bean in the Collection I'm able to access fine. After that I'm getting a Load failed message.
Does anyone have an idea how I can make this work?
Thanks,
Carles
Here is the code that makes the call:
try {
java.util.Collection usersCollection = home.findByCorporationId(1);
System.out.println("collection.size: " + usersCollection.size());
Iterator allUsers = usersCollection.iterator();
while (allUsers.hasNext()) {
Users users = (Users)allUsers.next();
System.out.println("name: " + users.getLogin());
System.out.println("login: " + users.getPassword());
}
} catch (Exception e) {
System.out.println("Exception: " + e);
e.printStackTrace();
}
Here is the console output, including the stack trace:
