[jboss-user] [JBoss jBPM] - Simple user list on datatable

[roccolocko]

Hello, Im simply trying to display a list of the jbpm users and their passwords, something very similar to what the login.jsp does on the jbpm webapp but I simply can't get it to work, this is what I'm doing:


  | private static List getUsers() 
  | 	{
  | 		 //Session session = JbpmContext.getCurrentJbpmContext().getSession();
  | 		Session session = JbpmConfiguration.getInstance().getCurrentJbpmContext().getSession();
  | 	    IdentitySession identitySession = new IdentitySession(session);
  | 	    return identitySession.getUsers();
  | 	  }
  | 	
  | 	private static List createUsersList() 
  | 	{
  | 	    List usersList = new ArrayList();
  | 	    Iterator iter = getUsers().iterator();
  | 	    while (iter.hasNext()) 
  | 	    {
  | 	    	User user = (User) iter.next();
  | 	    	usersList.add(new Usuario(user.getName(),user.getPassword()));
  | 	    }
  | 	    
  | 	    return usersList;
  | 	  }
  | 

then I try to use this to fill a datatable but doesn't work


  | <h:dataTable value="#{loginBean.usersData}" var="user">
  | 					<h:column>
  | 						<h:outputText value="#{user.username}" />
  | 					</h:column>
  | 				</h:dataTable>
  | 

The Usuario class is a simple class with only a constructor with setters an getters

  | public class Usuario {
  | 	
  | 	private String username;
  | 	private String password;
  | 	
  | 	public Usuario(String username, String password)
  | 	{
  | 		this.username = username;
  | 		this.password = password;
  | 	}
  | . . .
  | }
  | 

The jsp gives me the next error

  | javax.servlet.ServletException: Cannot get value for expression '#{loginBean.usersData}'
  | 

I'm new to both JSF and jBPM, so I'm really not sure where the mistake could be but I pretty much follo the UserBean class on the jBPM webapp, just adding the Usuario class to fill both username and password.
