SEAM don't can find session bean !!

[johnbat26]

Hello.
I have next problem with SEAM (1.2.1.GA)
-------------------------------
My config:
JSF: jsf-1.2_04-b10-p01
SEAM: 1.2.1.GA
JBoss: 4.0.5.GA
OS: Gentoo Linux (AMD64)
VM: BEA JRockIt 6.0 and Sun JVM 6.0
---------------------------------
I created one entity (User) and one Session Bean (UserActionBean).
This is my ejb-jar.xml:
---------------------------
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar
xmlns="http://java.sun.com/xml/ns/javaee"

So, SEAM don't can find properly deployed session bean!!!
What I do wrong ?
Very wait answer....

[johnbat26]

Do really nobody know how resolve this trouble ?

[waynebagguley]

do you have seam.properties in the right place?

[shane.bryzak]

Post the code for your session bean.

[johnbat26]

waynebagguley: Yes, I put seam.properties (size: 0 b)

-----------------------------------

[waynebagguley]

Don't you need an @Begin somewhere?

[johnbat26]

Why I must add @Begin annotation to Session bean, and where I must put it.

[waynebagguley]

Try adding @Begin(join=true) to the action method that is getting called

[shane.bryzak]

Your session bean has no local interface.

[johnbat26]

[e-mail]: My session bean has the local interface:
--------------
package org.it.itMail.service;

/**
* Local component interface for the UserActionBean session bean.
*
*/
public interface UserActionLocal
{

// ----------- Accessors For Constants ------------


// ------------ Business Methods -----------------

/**
*
*/
public org.it.itMail.domain.User getUser(java.lang.Integer id);

/**
*
*/
public void getUsers();


// ------------ Lifecycle Methods -----------------

public void destroy();
}
----------------

[gavin.king]

Then it needs to implement that interface!

[stu2]

Your local interface must be annotated with @Local, right?

[johnbat26]

I try recreate my project again. But SEAM don't find session bean afresh ! :(((((((((

This is my local interface:
--------------------------------
package org.it.itMail.service;

/**
* Local component interface for the UserManagerBean session bean.
*
*/

// ----------- Accessors For Constants ------------


// ------------ Business Methods -----------------

/**

HELP, PLEASE ...

[stu2]

Again, is your interface annoted with @Local, as required by the spec?

I didn't see it if so. Try adding it, so your interface declaration looks like this:

@Local
public interface UserManagerLocal
{
...

You may also have an easier time if you play with seam-gen a bit. Create a new project, add a few actions, and see what the code it creates looks like. Even if you just throw it away afterwards, you may find it helpful (I did).

I change local interface:
-----------------------------------------
package org.it.itMail.service;

import javax.ejb.*;

/**
* Local component interface for the UserManagerBean session bean.
*
*/
@Local
public interface UserManagerLocal
{

// ----------- Accessors For Constants ------------


// ------------ Business Methods -----------------

/**
*
*/
public java.util.List loadUsers();

}
-----------------------------------------

But SEAM don't find session bean again !!!
:(((((((((
