Hi ,
I am developing a
EJB Applicaion using EJB CMP 2.0 spec. I am using
JBOSS 4,0,3 as an appln server. My all ejb's are working fine when i am accessing them through my client file using remmote interface. But problem comes When i access one of my ben using same client that i ve used to access other EJB's.(ofcourse JNDI name will be differnt for each EJB in client). It gives me error like:-
==================
java.rmi.UnmarshalException: Error unmarshaling return; nested exception is:
java.lang.ClassNotFoundException: org.postgresql.util.PSQLException (no security manager: RMI class loader disabled)
===================
& my client code is:-
===========================
import java.sql.Timestamp;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import javax.transaction.UserTransaction;
//all import classes related to EJB's interfaces here//
public class Client {
private static UserTransaction utx = null;
public static void main(
String[] args) throws Exception {
Context initialContext = null;
try {
Hashtable h = new Hashtable();
h.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
h.put(Context.PROVIDER_URL, "localhost:1099");
initialContext = new InitialContext(h);
} catch (Exception e) {
System.err.println("Cannot get initial context for JNDI: " + e);
System.exit(2);
}
System.out.println("Getting a UserTransaction object from JNDI");
try {
utx = (UserTransaction) initialContext.lookup("UserTransaction");
} catch (Exception e) {
System.err.println("Cannot lookup UserTransaction: " + e);
System.exit(2);
}
// Connecting to Home thru JNDI
System.out.println("Connecting to the CDBeanHome");
EnquiryMasterHome home = null;
try {
home = (EnquiryMasterHome)PortableRemoteObject.narrow(
initialContext.lookup("ejb/EnquiryMaster"),
EnquiryMasterHome.class);
} catch (Exception e) {
System.err.println("Cannot lookup :" + e);
System.exit(2);
}
System.out.println("Creating a new CDBean in database");
EnquiryMaster a1 = null;
try {
a1 = home.create("E000023","23",new Timestamp(System.currentTimeMillis()),"C000230","no comments","no terns","Prashant","Pending",true);
} catch (Exception e) {
System.err.println("Cannot create CDBean: " + e);
System.exit(2);
}
}
}
===========================
I don't know what is problem. The same code of above client is working fine for my all other beans. But its only not working with my single bean whose JNDI name is:-"ejb/EnquiryMaster"
What is problem here. Please help me. Thanx in advance..
