CMP Bean seems to change its id in cache?
Hi
I badly need your help!
Using jboss3.2.3 and mysql, I create a cmp bean called userEJB. The problem is:
when I create a new bean, jboss cache this bean in an existed bean instance, then this new bean using an old id will be store into my db; on the other hand, jboss insert a new user with new id but old user information into my db.
my code goes here:
Remote:
public interface User extends EJBObject {
public UserDetails getDetails() throws RemoteException;
public void setDetails(UserDetails userDetails) throws RemoteException;
}
Home:
public interface UserHome extends EJBHome {
public User create(UserDetails userDetails)
throws RemoteException,CreateException;
public User findByPrimaryKey(Integer pk)
throws FinderException, RemoteException;
public Collection findByNameAndPwd(String userName,String pwd)
throws FinderException, RemoteException;
public Collection findAll()
throws FinderException, RemoteException;
public Collection findByUserName(String userName)
throws FinderException, RemoteException;
}Bean:
public abstract class UserEJB implements EntityBean{
private EntityContext context;
private UserDetails userDetails;
public Integer ejbCreate(UserDetails userDetails) throws CreateException{
setUserID(userDetails.getUserID());
setDetails(userDetails);
return null;
}
public void ejbPostCreate(UserDetails userDetails){}
public UserDetails getDetails() {
userDetails = new UserDetails();
userDetails.setUserID(getUserID());
userDetails.setUserName(getUserName());
userDetails.setPassword(getPassword());
userDetails.setDate(getDate());
return userDetails;
}
public void setDetails(UserDetails userDetails) {
setUserName(userDetails.getUserName());
setPassword(userDetails.getPassword());
setDate(userDetails.getDate());
}
public void setEntityContext(EntityContext ctx){
context = ctx;
}
public void unsetEntityContext(){
context = null;
}
public void ejbActivate(){userDetails = null; }
public void ejbPassivate(){userDetails = null; }
public void ejbLoad() {}
public void ejbStore() {}
public void ejbRemove() { }
public abstract java.sql.Date getDate();
public abstract String getPassword();
public abstract Integer getUserID();
public abstract String getUserName();
public abstract void setDate(java.sql.Date date);
public abstract void setPassword(String string);
public abstract void setUserID(Integer integer);
public abstract void setUserName(String string);
