Hi all,

I am using jboss-3.0.6, I have created user Entity bean my entity bean code is

public class UserBean implements EntityBean {

public UserDetails userDetails = null;

public String userId = null;

private EntityContext context;

public String ejbCreate(String userId, UserDetails userDetails) {

this.userId = userId;
this.userDetails = userDetails;

return this.userId;
}

public void ejbPostCreate(String userId, UserDetails userDetails) {
}

public String ejbFindByPrimaryKey(String userId)
throws FinderException {

return this.userId;
}

public void setEntityContext(EntityContext context) {
this.context = context;
}

public void unsetEntityContext() {
this.context = null;
}

public void setUserDetails(UserDetails userDetails) {
this.userDetails = userDetails;
}

public void setUserId(String userId) {
this.userId = userId;
}

public UserDetails getUserDetails() {
return this.userDetails;
}

public String getUserId() {
return this.userId;
}

public void ejbActivate() {
}

public void ejbLoad() {
}

public void ejbPassivate() {
}

public void ejbRemove() {
}

public void ejbStore() {
}
}

In above Entity bean UserDetails class which implements Serializable class I am call above entity like

User user = getUserHome().findByPrimaryKey(userId);

System.out.println(">>>>>>"+ user);
System.out.println(">>>>>>"+ user.getUserId());

am getting following error ...when we trying to call getUserId() method.
