SOS: javax.ejb.CreateException: Create failed because primary key is null

Question

Hello,
I am desperately trying to get my application server to create a record through CMP 2. My app server is JRun 4.
Here is the client:
package com.parispano.tests;
import java.util.Date;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.parispano.account.entity.Account;
import com.parispano.account.entity.AccountHome;
public class ClientEJBDeuxTemp {
  public static void main(String[] args) {
    System.out.println("\nBegin account DemoClient...\n");
    try {
      // Create A Demo object, in the server
      // Note: the name of the class corresponds to the JNDI
      // property declared in the DeploymentDescriptor
      // From DeploymentDescriptor ...
      // beanHomeName demo.DemoHome
      Context ctx = getInitialContext();
      AccountHome ahome = (AccountHome) ctx.lookup("AccountEJBHome");
      //System.out.println("Creating Demo\n");
      Account account = ahome.create("toto","toto", "toto","toto","toto","toto","toto","toto","toto","toto","toto",new Date(),new Date());
    catch (Exception e) {
      System.out.println(":::::::::::::: Error :::::::::::::::::");
      e.printStackTrace();
    System.out.println("\nEnd DemoClient...\n");
  static String user     = "admin";
  static String password = "admin";
  static String url      = "ordi:2908";
   * Gets an initial context.
   * @return                  Context
   * @exception               java.lang.Exception if there is
   *                          an error in getting a Context
  static public Context getInitialContext() throws Exception {
    Properties p = new Properties();
    p.put(Context.INITIAL_CONTEXT_FACTORY, "jrun.naming.JRunContextFactory");
    p.put(Context.PROVIDER_URL, url);
    if (user != null) {
      System.out.println ("user: " + user);
      p.put(Context.SECURITY_PRINCIPAL, user);
      if (password == null)
        password = "";
      p.put(Context.SECURITY_CREDENTIALS, password);
    return new InitialContext(p);
}and here is the exception I get:
javax.ejb.CreateException: Create failed because primary key is null
I don't understand why I get this as the primary key is "toto" and therefore is not null.
Here is the DD:

Answer 1

Yes, I have set the PK. Actually this is happening when the number of columns are more than 63 columns. After I reduce the number of column, it is working fine.
Is it the actual problem???
fyi, I'm using jboss as the Application Server...
