[JBoss-user] [JBoss Seam] - Re: Seam mailer component

[<nor...@jb...>]

Do we have a component registry?  It might be interesting to start collecting some of these to give seam developers more tools to choose from.

[gus888 <do-...@jb...>]

Petemuir and Gavin,

Thank you very much for your directions, I fixed my problem after removing javax.faces.CONFIG and recoding my web.xml.

I have one more question, did anyone ever combine faces/tiles with facelets? Or is it possible? Thank you. 

Best regards,

GUS

Nice. It might be worth including this in Seam.

Can commons-email also be used for processing incoming emails? If so, could get something decent be combining this with JCA message inflow mapped to a message-driven bean.

[JBoss-user] [JBoss Seam] - Problems with pages.xml...

[bkyrlach <do-...@jb...>]

I'm replacing part of a struts web application with Seam and I'm having some strange problems with pages.xml

Problem one: I have a pages.xml that runs an action on pageload that grabs some request values and stores them in a session scoped Seam component so that I can use them later. However, when I preform any action on said page that would navigate me to a new page, the action defined for this page runs again. Since the request parameters are now lost, this results in all the values in my bean being nulled out, and my application throws null pointer exceptions.

pages.xml

   <page view-id="/ben/infozap.xhtml" action="#{infozapAction.createInfoZapDTO}"/>


InfoZap action:
@Stateless
@Name("infozapAction")
@Interceptors(SeamInterceptor.class)
public class InfozapActionImpl implements InfozapAction
{
    @RequestParameter
    String[] schoolList;
    
    @RequestParameter
    String productAreaID;
    
    @RequestParameter
    String infozapType;
    
    @RequestParameter
    String productTypeID;
    
    @Out
    private InfoZapDTO izdto;
    
    //@In(create=true) 
    //private Redirect redirect;
            
    public void createInfoZapDTO()
    {
        izdto = new InfoZapDTO();
        
        if(schoolList != null)
        {
            izdto.setSchoolList(schoolList);
        }
        
        if(productAreaID != null)
        {
            izdto.setProductAreaID(productAreaID);
        }
        
        if(infozapType != null)
        {
            izdto.setInfozapType(infozapType);
        }
        
        if(productTypeID != null)
        {
            izdto.setProductTypeID(productTypeID);
        }
        //redirect.setViewId("/ben/infozap.jsf");
        //redirect.execute();
    }    
}

infozap.xhtml
...
<h:commandButton action="#{someActionClass.someAction}"/>
...

Problem two: In light of the above, I made a dummy page and edited the URL pattern in pages.xml to fire my action when the dummy page is navigated to. I edited the action to redirect to the correct page after it grabs the request values. I can see in my code that the method is fired, but even though I outject the member variable, after the redirect, it's no longer available

pages.xml

   <page view-id="/ben/test.xhtml" action="#{infozapAction.createInfoZapDTO}"/>


InfoZap action:
same as above with redirect lines uncommented

Any help would be greatly appreciated.

[JBoss-user] [JBoss Seam] - Re: Breaking changes to pageflow

[rpiaggio <do-...@jb...>]

"nor...@jb..." wrote : Have your start-node transition directly to a decision node.  When the process is signaled, you will go through the decision node and, I assume, to a page node for display.  If you are in the situation mentioned where you need use start-page, you I guess you'd need to find a way to inject the actual process instance somewhere and signal it.

That's what I am doing but the change described above seems to break the correct behavior.

Here's how my pageflow starts:

  | <pageflow-definition
  |   name="PaymentAuthorization">
  |    <start-state name="start">
  |    	  <transition to="selectSource">
  |    	  	  <action expression="#{sourceManager.selectSource}"/>
  |    	  </transition>
  |    </start-state>
  | 
  |    <decision name="selectSource" expression="#{sourceManager.result}">
  |       <transition name="abort" to="menu"></transition>   
  |       <transition name="proceed" to="requestPin"></transition>
  |       <transition name="chooseSource" to="chooseSource"></transition>
  |    </decision>
  | 

If the pageflow is started from this method via a POST it works:

  | 	@Begin(pageflow="PaymentAuthorization")
  | 	public	void	start() {		
  | 	}
  | 

However, if I started via a GET (calling the above method via pages.xml) or via a method anneotated like this:

  | 	@Begin(ifOutcome="proceed", pageflow="PaymentAuthorization")
  | 	public	String	initiate() {
  | 		...
  | 	}
  | 

then I get the following:java.lang.ClassCastException: org.jbpm.graph.node.StartState
  | 	at org.jboss.seam.core.Pageflow.getPage(Pageflow.java:129)
  | 	...

which seems to be a direct result of the change described above, since the start node is forced to cast to a Page, which of course fails if it is a <start-state> instead.

Any ideas on how to start with a decision when forced to start with a page?

[JBoss-user] [JBoss Seam] - Re: Long running transaction - multiple save points?

[<gav...@jb...>]

I think your approach with merge() in a non-transactional method is the correct one. HEM should _not_ throw an exception if the PC is an extended PC. So either (a) your PC is not an extended PC and it should be or (b) this is a bug in HEM.

[denis-karpov <do-...@jb...>]

Hello.

May I ask here about implementation details?

Gavin, why do you keep conversation scope variables directly in the session context map?
Why do we need so complicated scheme with ?additions? and ?removals? in the ServerConversationContext? What if we have just a simple Map inside ConversationEntry, for instance?

Thanks.

[JBoss-user] [EJB 3.0] - Re: SocketException with an MDPOJO

[malmei <do-...@jb...>]

I put more research into it - it seems that this one is not deadly. I can send 1000 messages, close the ProducerManager, get the Exception and then can just send the next 1000 messages (with a new ProducerManager). 

If it's true, that the Exception means that the client is not reading messages from the server, then my DLQ will not be happy about it.

So it's possibly more than just a cosmetic problem ...

Right, you should definitely not use javax.faces.CONFIG_FILES to reference /WEB-INF/faces-config.xml.

I don't know what your other exceptions are about, I have never seen them before. Probably not related to Seam.

[JBoss-user] [JBoss Seam] - Entities with one/many_to_many relationships and SEAM

[trouby <do-...@jb...>]

Hey guys,

I was wondering,

Assuming I have an entity with one_to_many relationship, i.e:

  | class X {
  |   String name;
  |   Collection<Y> yList;
  | 
  |    @Column(name="NAME")
  |    public long getName() {
  |        return name;
  |    }
  |     
  |     public void setName(String name) {
  |         this.name = name;
  |     }
  | 
  | 
  |   @OneToMany(mappedBy="x")
  |   public Collection<Y> getyList() {
  |       return yList;
  |   }
  | 
  |   public setYList(Collection<Y> yList) {
  |     this.yList = yList;
  |   }
  | }
  | 


Assuming I'd like to build some web GUI for class X, but except simple fields (such as name) I'd also like to set multiple Y entities to the collection  of the X class through a WEB interface,

Does Seam supports this easily? or i'll have to create a 'multiple selectbox' and pass IDs of Y entities, load the Y entities and set them into the collection by myself?

Thanks a lot,

Asaf.

[JBoss-user] [JBoss jBPM] - Re: re : Decision Hanlder

[cpob <do-...@jb...>]

You have to add the Handler to the decision node for it to work.

Look at the API for Decision.

There's a setAction method.  Create a new action and set it to the decision object using that method.

You'll have to investigate what creating a new action involves (you have to create a new Action Delegation).

[JBoss-user] [JBoss Portal] - Sharing Portal Sessions and User Information

[snig178 <do-...@jb...>]

Hi folks,

I'm working on a web site which needs to integrate web pages generated using different technology, such as PHP and Ruby On Rails. The backbone of the web site is going to based on the Portal, due mainly to the content management system but also because most existing work is in Java.

Our problem is the synchronisation between the portal, using JBOSS and the other web applications (using a variety of technology). How accessible to these web applications is the user information? Do portals include any methods to assist single-signon?

I'd appreciate any help or advice you can give me?
