Cannot deploy EntityBean from Weblogic 5.1

Question

Hi everyone,
I'm relatively new to EJB deployment, but there is an Entity bean that I was able to deploy using Weblogic 4.0 and fail to do the same with Weblogic 5.1, although I'm going through all the necessary steps, like creating xmls (ejb_jar, weblogic-cmp-rdbms-jar, and weblogic-ejb-jar), creating a jar file, and recompiling it using weblogic.ejbc, and that's where it stops. While it works fine with session beans, every time I'm trying to deploy entity bean, it gives me the following message:
ERROR: Error from ejbc: [9.1.5.1] In EJB EmployerEntityEJB, there is an ejbPostCreate method ejbPostCreate() that has no matching ejbCreate method.
Yet my ejbCreate and ejbPostCreate methods do match, unless I'm missing something, but at this point I have no idea what exactly. Any kind of help would be great, 'cause I'm almost out of ideas.
Here's the code I'm working on:
EmployerEntity.java:
import java.rmi.*;
import java.sql.*;
import javax.ejb.*;
import java.util.*;
public interface EmployerEntity extends EJBObject, Remote {
public boolean postingUpdate(Hashtable posting) throws RemoteException,SQLException;
public void callingBreakHashtable(Hashtable posting) throws RemoteException;
EmployerEntityHome.java:
import java.rmi.*;
import javax.ejb.*;
import java.io.*;
import java.util.*;
import javax.naming.*;
public interface EmployerEntityHome extends EJBHome{
public EmployerEntity create(Hashtable posting) throws RemoteException, EJBException, CreateException;
public EmployerEntity findByPrimaryKey(EmployerEntityPK job_id) throws FinderException,RemoteException;
public EmployerEntity findByPosition(int job_id) throws FinderException,RemoteException;
EmployerEntityPK.java:
import java.io.Serializable;
public class EmployerEntityPK {
public int job_id;
and finally EmployerEntityBean.java (I left only ejbCreat and ejbPostCreate methods, so that I won't confuse anybody):
import java.io.*;
import java.util.*;
import javax.ejb.*;
import javax.naming.*;
import java.rmi.*;
import java.sql.*;
//and local classes
public class EmployerEntityBean extends LocalClassEntityBean {
Hashtable posting=new Hashtable();
public EmployerEntityBean() {}
public EmployerEntityPK ejbCreate(Hashtable posting) throws EJBException, CreateException {
if (posting_entity_flag)
this.posting=posting;
callingBreakHashtable(posting);
Syslog.debug(this,"EJBCreate Called ");
return null;
public void ejbPostCreate(Hashtable posting) throws EJBException {
Syslog.debug(this,"EJBPostCreate Called ");
Thanks for your help.
PS. Also, could it be that the error that I'm getting might be caused by something other than simply mismatching ejbCreate and ejbPostCreate? If so, what are the other possible reasons?
Thanks

Hi,
First of all, you don't need to add EJBException in your method definition as its a runtime exception. Next your ejbPostCreate() is missing the CreateException and thats the reason you have a mismatch.
Also your remote interface should extend EJBObject ( which is a subclass of java.rmi.Remote). Catch the SQLException and rethrow it as an EJBException with proper message. And finally I take it that LocalClassEntityBean implements EntityBean.
Best wishes
