First: Don't hijack other people's thread. Create a new one (don't hit reply
and just change the topic).
Second: Read the wiki article again and compare it with what you got.

Hi,
I am trying to integrate tapestry5 with Hibernate. I have done all steps which are defined in http://wiki.apache.org/tapestry/Tapestry5HowToUseTapestryHibernate .
It is compiling without errors but when i run HbAction page it gives me exceptions.
org.example.example1.web.pages.HbAction.onAction(HbAction.java:29)
org.example.example1.web.services.AppModule$1.service(AppModule.java:90)
Please help if you have any ideas?
Thank you,
my codes are as bellow:
Hello.java
package org.example.example1.web.entities;
/**

@Entity
@Table(name="hello")
public class Hello {
@Id
@GeneratedValue
private long id;
private String message;
public long getId() { return id;}
public void setId(long id) { this.id = id; }
public String getMessage() { return message;}
public void setMessage(String message) { this.message = message;}
}
HbAction.java
import java.util.List;
import org.apache.tapestry5.ioc.annotations.Inject;
import org.example.example1.web.entities.Hello;
import org.hibernate.Session;
public class HbAction {
@Inject
private Session _session;
private Hello current;
public void onAction() {
Hello h = new Hello();
h.setMessage("Hello World");
_session.save(h);
_session.close();
}
public List getList() {
return _session.createCriteria(Hello.class).list();
}
public Hello getCurrent() {
return current;

this.current = current;
