ClassCastException in generated CMP Proxy
Hi all,
I m trying to setup a EJB based application using XDoclet. I ve created one EntityBean for every DB-Entity. The second step was to create a TestClient which connects, using the JNDI Name, to a SessionBean.
Now the SessionBean uses the Local Interface to get the Value Object of the specified entity. The ValueObjects will be put into a Collection and will be sent back to the Client.
The error which occured is in a generated CMP class.
thanx a lot and krgds

Some piece of code:
TestClient:
public static void main(String[] args) {
/*TestClient t = new TestClient();
//t.printGangsterMdr();
t.testRelations2();
*/
Properties props = new Properties();
System.setProperty(
InitialContext.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
System.setProperty(
InitialContext.PROVIDER_URL,
"jnp://servername:1099");
TestClient t = new TestClient();
t.init();
}
private MdrStatusViewSessionHome getMdrStatusView()
throws NamingException {
return (MdrStatusViewSessionHome) getContext().lookup(
MdrStatusViewSessionHome.JNDI_NAME);
}
private void init() {
try {
System.out.println("[Method] Init");
MdrStatusViewSession sess = getMdrStatusView().create();
Collection c = sess.getDataFeeds();
Iterator it = c.iterator();
while (it.hasNext()) {
DataFeedValue dv = (DataFeedValue) it.next();
System.out.println(dv.toString());
}
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (CreateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
SessionBean:
/**
* @ejb.interface-method
*/
public ArrayList getDataFeeds() {
ArrayList dfs = new ArrayList();
try {
//Collection c = DataFeedUtil.getHome().findAll();
Collection c = this.getDataFeedLocalHome().findAll();
System.out.println("Datafeeds: " + c.size());
Iterator it = c.iterator();
while (it.hasNext()) {
DataFeedLocal df = (DataFeedLocal) (it.next());
DataFeedValue dv = df.getDataFeedValue();
}
} catch (FinderException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return dfs;
}
