Error in accesing CMP Bean........

[tiwari_p_k]

Hi,
I am developing a simple bean application. The Bean gets deployed successfully. But the problem is that when i run client against bean for inserting data in database i get following error.
=======
15:10:30,593 ERROR [CartMaster] Error checking if entity exists
java.sql.SQLException: ERROR: syntax error at end of input

My code for Client application is:-
===================
package econify.eb;

import java.util.Hashtable;

import javax.transaction.UserTransaction;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;
import javax.naming.*;

public class testClient {

private static UserTransaction utx = null;

public static void main(String[] args) {

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL,
"localhost:1099");
Context initialContext=null;
try {
initialContext = new InitialContext(env);

} catch (Exception e) {
System.err.println("Cannot get initial context for JNDI: " + e);
System.exit(2);
}

// We want to start transactions from client: get UserTransaction
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");
testHome home = null;
try {
home = (testHome)PortableRemoteObject.narrow(initialContext.lookup("ejb/testbeanHome"),
testHome.class);
} catch (Exception e) {
System.err.println("Cannot lookup "+": " +e);
System.exit(2);
}
// Create a first CDBean
System.out.println("Creating a new CDBean in database");
test a1 = null;
try {
System.out.print(home.getEJBMetaData().toString());
a1 = home.create("Prashant","prashantpassword");

System.out.println("Created cd bean successfully ......");

} catch (Exception e) {
System.err.println("Cannot create CDBean: " + e);
System.exit(2);
}
}
