Regarding Outjecting and Injecting

[sriramsudheer]

Hi i have two components and both are SFSB. I am trying to outject a third component in one SFSB and inject it in another
SFSB. I am acessing the second SFSB in jsf tags and i am acessing lots of times. I can see component been injected first time but then for the second request the component injected is null.
         
My primary question is how can i outject a component so that it lasts for any number of injections because from the document i can see the outjected component will be disinjected  after first injection.

Sorry if i am not clear :(

This is the following code

1st component:

package com.landmarkSoftware.dv03.deploy.session;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
import java.util.Set;

import javax.ejb.Remove;
import javax.ejb.Stateful;
import javax.ejb.Stateless;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Destroy;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Out;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.log.Log;
import org.jboss.seam.security.Identity;

import com.landmarkSoftware.dv03.dao.global.AuthenticateDao;
import com.landmarkSoftware.dv03.dao.global.GlobalDao;
import com.landmarkSoftware.dv03.deploy.entity.global.Function;
import com.landmarkSoftware.dv03.deploy.entity.global.Role;
import com.landmarkSoftware.dv03.deploy.entity.global.User;
import com.landmarkSoftware.dv03.deploy.session.local.IAuthenticatorLocal;

@Stateful
@Name("authenticator")
@Scope(ScopeType.SESSION)
public class Authenticator implements IAuthenticatorLocal
{
    @Logger Log log;
    
    @In Identity identity;
    
    @In
    GlobalDao globalDao;
    
    @Out(value="user")
    private User authentictedUser;
    
    public boolean authenticate()
    {
        log.info("authenticating #0", identity.getUsername());                
        String userName = identity.getUsername();
        String password = identity.getPassword();
        AuthenticateDao authenticateDao = globalDao.getAuthenticateDao();
        User user = authenticateDao.authenticate(userName, password);
        
        if(user!= null) {
             authentictedUser = user;
             log.info("User Authenticated", authentictedUser.getUserUsername());
             return true;
        }else {
             return false;
        }     
    }
    
    //The Roles to applications are collection of functions available to user
    public void installRolesToApplication(User user) {
          Set<Role> roles = user.getRoles();          
          for(Role role: roles) {
               Set<Function> functions = role.getFunctions();
               for(Function function: functions) {
                    identity.addRole(function.getFunctionName());
               }
          }
     }
        
    @Remove
    @Destroy
    public void destroy() {
         
    }
}

2nd component:

package com.landmarkSoftware.dv03.deploy.session;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;

import javax.ejb.Remove;
import javax.ejb.Stateful;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.AutoCreate;
import org.jboss.seam.annotations.Create;
import org.jboss.seam.annotations.Destroy;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.security.Restrict;
import org.jboss.seam.log.Log;

import com.landmarkSoftware.dv03.deploy.entity.global.Function;
import com.landmarkSoftware.dv03.deploy.entity.global.Role;
import com.landmarkSoftware.dv03.deploy.entity.global.User;
import com.landmarkSoftware.dv03.deploy.session.local.IAuthenticatedFunctionListRemote;

@Stateful
@Name("authenticatedFunctionList")
@Scope(ScopeType.SESSION)
public class AuthenticatedFunctionList implements IAuthenticatedFunctionListRemote, Serializable{
     
     /**
      * 
      */
     private static final long serialVersionUID = 1L;

     @In(required=false)
     User user;
     
     @Logger
     Log log;
     
     List<Function> authFunctionList;
     
     
     public void loadAuthenticatedFunctionList() {
          authFunctionList = new ArrayList<Function>();
          
          if (user != null) {
               log.info("The injected User value is not null");
               Set<Role> roles = user.getRoles();
               for (Role role : roles) {
                    Set<Function> functions = role.getFunctions();
                    for (Function function : functions) {
                         authFunctionList.add(function);
                    }
               }
          }else {
               log.info("The Injected User value is Null");
          }
     }
     
     @Destroy
     @Remove
     public void destroy() {
               
     }

     
     public List<Function> getAuthFunctionList() {
          loadAuthenticatedFunctionList();
          return authFunctionList;
     }
     
}

My facelet code: which is a template and so lot of calls to second SFSB:

 <ui:repeat xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:s="http://jboss.com/products/seam/taglib"
    xmlns:rich="http://richfaces.org/rich"
    value="#{authenticatedFunctionList.authFunctionList}" var="eachFunction">         
         <s:link value="#{eachFunction.functionName}" propagation="none" rendered="#{identity.loggedIn}">
         <br/>         
         </s:link>         
 </ui:repeat>

1. {authenticatedFunctionList.authFunctionList} is becoming null second time because of diinjection.
