get a "ArrayIndexOutOfBounds"When I access a CMP

[lyo Yashnoo]

Hello everyone:

I deploy a EJB(CMP) successfully in weblogic8.But I get a Exception "ArrayIndexOutOfBoundsException" When I invoke it using code:
////////////////////////invokeejb.jsp/////////////////////////////////

 Properties pro=new Properties();
pro.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
pro.put(Context.PROVIDER_URL,"t3://127.0.0.1:7001");
Context ctx=new InitialContext(pro);
System.out.println("Debug...");
Object obj=ctx.lookup("CustomerEJB");
System.out.println("after lookup...");
CustomerHomeRemote home=(CustomerHomeRemote)PortableRemoteObject.narrow(obj,CustomerHomeRemote.class);
//create customers
Integer primary=new Integer(1);

CustomerRemote remote=home.create(primary);
remote.setFirstName("lyo");
remote.setLastName("Yashnoo");
CustomerRemote customer=home.findByPrimaryKey(primary);
String first=customer.getFirstName();
String last=customer.getLastName();
System.out.println("first name is"+first);
System.out.println("=================");
System.out.println("last name is"+last);
 

I have a record in MySQL Database and I have already mapping the record to the cmp field.
My EJB home interface is:
/////////////////////////////////////////

 public CustomerRemote create(Integer id)throws CreateException,RemoteException;
public CustomerRemote findByPrimaryKey(Integer id)throws FinderException,CreateException,RemoteException; 

Why it arrayoutofbound ?
