Remoting Callback

[srpantano]

I made a remote test and the call to class method it's fine, but the callback method is never called in page, why?

My class:

@Name("configuratorAction")
@Scope(ScopeType.CONVERSATION)
public class ConfiguratorAction { // extends EntityController {
    @WebRemote
    public String getRemoteModule(String module) {
        return "aaa";
    }
}

and my page:

<script type="text/javascript" src="#{facesContext.externalContext.requestContextPath}/seam/resource/remoting/resource/remote.js"></script>    
<script type="text/javascript">
     //<![CDATA[
     jQuery.noConflict(); //Retira os conflitos com o Richfaces            
            
     jQuery(window).bind("load",function(){
            
         jQuery("input.buttonModule").click( function() {
             changeModule();
         });
            
     });
            
     function changeModule() {
                
         var jqModule = jQuery("select.modules").val();
         var confComponent = Seam.Component.getInstance("configuratorAction");
                
         confComponent.getRemoteModule(jqModule, remoteModuleCallback);
                
     }
            
     function remoteModuleCallback(result) {
          alert("Hi!");                
     }
     // ]]>
</script>

I don't see any include for your remote component.

You should have something like the following located somewhere:

<s:remote include="configuratorAction"/>

Although if you are saying that the call is working on the remote class then you probably do.

[samdoyle]

If not using tags then something like this:

<script type="text/javascript" 
        src="seam/resource/remoting/interface.js?configuratorAction"></script>

[srpantano]

I put this (script tag), but still does not work!

[samdoyle]

Also don't you need a local interface in which you define the WebRemote method signature? Look at the remoting example included with the Seam distribution.

S.D.

[srpantano]

But in the Seam's Wiki example they are using JavaBean classes.

Which browser are you using?  Do you have any javascript errors in the browser?  If using Firefox, I would highly recommend FireBug for debugging browser stuff.

[srpantano]

I'm using Firefox with Firebug, but it doesn't show a error. It process the class method normaly, but doesn't call the Callback in javascript.

[keithnaas]

Inside of the remote.js, does it show the ajax call completing?

Set a breakpoint in Seam.Remoting.requestCallback and see if the req.readyState is ever 4 and if the req.status is ever 200.

[srpantano]

if I turn on the debug, Firebug's console of debug show:

if (req.status == 200)

at line 650.

[shane.bryzak]

Turn on remoting's debug mode, either in JavaScript:

Seam.Remoting.setDebug(true);

Or in components.xml:

    <component name="org.jboss.seam.remoting.remoting">
      <property name="debug">true</property>
    </component>

That way you'll see the request and response packets that are sent/received from remoting.

[srpantano]

It was I do! I turn on the debug and in debug's window shows:

if (req.status == 200)

at line 650 in remote.js

Do you have the Seam resource servlet configured correctly in web.xml?

[srpantano]

Yes, I have!

<servlet>
   <servlet-name>Seam Resource Servlet</servlet-name>          
    <servlet-class>org.jboss.seam.servlet.SeamResourceServlet</servlet-class>
</servlet>
<servlet-mapping>
   <servlet-name>Seam Resource Servlet</servlet-name>
   <url-pattern>/seam/resource/*</url-pattern>
</servlet-mapping>
