[JBoss Seam] - Error while using remoting with Home objects?
by jquery＠interia.pl
Hi,
I have the following code:
| /*TestAction.java*/
| @Stateless
| @Name("testAction")
| public class TestAction extends EntityHome<Category> implements TestActionInterface{
|
| public String testName(String name){
| return "Hello, "+name;
| }
|
| @Remove
| public void destroy(){}
| }
|
|
| /*TestActionInterface.java*/
|
| @Local
| public interface TestActionInterface {
| @WebRemote
| public String testName(String name);
|
| @WebRemote
| @Remove
| public void destroy();
| }
|
| /*testfunctions.js*/
|
| function callAjax(name){
|
| Seam.Remoting.setDebug(true);
|
| Seam.Component.newInstance('testAction').testName(name, sayHaloCallback);
|
| };
|
| function sayHaloCallback(result){
| alert(result);
|
| }
|
|
And it works fine. But I need to invoke a method from the Home object, so I uncomment "extends EntityHome".
In this case I get the following error:
| ERROR [ContextualHttpServletRequest] ended request due to exception

What am I doing wrong and how can I invoke method from Home object using remoting mechanism?
And the next question is why Home objects can't be @Stateless? When I change @Stateful annotation (in TestAction.java) into @Stateless I get the following error:

Actually I don't have any @Create annotation declared!
Thanks for help and explanations in advance.

[JBoss jBPM] - Re: Combo Box in Form
by kukeltje
anonymous wrote : anonymous wrote : Yet, I do not disagree that a nicer solution would be 'handy' and seam provides parts of that for you. what you encounter now is in the grey area of the webconsole. What is it intended for? Production systems? well, the management part should be. Is it intended for end-users? No currently not. So some things are not in there and personally I use the storage of variables only in the RAD/Prototype part of a project. For productionsystems we have a separate domain model and use a separate database for that (with separate ui) so the list of selectitems comes from there and not jBPM. The selected value goes into jBPM.
| Thanks a lot, I haven't seen that so clear so far. I should reconsider my approach here.
Think e.g. about
- wizards, pageflow not tasks... they do not fit in the webconsole. But are often required in a real production system. Seam has them.
- Starting processes in a scheduled way... seam (quartz) can help out
- ....
Things that are not that high on the requirementslist for a prototype.
(shameless plug ;-))
Ok, now back to the jBPM persistence problem.... yes, you got me convinced.
I'm curious though what would happen if you changed
System.out.println("first.node-enter: directly after setting variable: instanceof selectitem:"+(test.get(0) instanceof javax.faces.model.SelectItem));
to
System.out.println("first.node-enter: directly after setting variable: instanceof selectitem:"+(executionContext.getContextInstance().getVariable("selectitems").get(0) instanceof javax.faces.model.SelectItem));
I do not have access to a jBPM engine now, so cannot test this myself. This would maybe even rule out persistence .
you also ruled out a classloading issue, but showed a map works.... STRANGE...
I also wonder is something like this would work or if it would throw a classcastexception...
| public List getItems() {
| List elements = executionContext.getContextInstance().getVariable("selectitems");
| Iterator i = elements.iterator();
| List retVal = new LinkedList();
|
| while(i.hasNext()) {
| javax.faces.model.SelectItem element = (javax.faces.model.SelectItem) i.next();
| javax.faces.model.SelectItem item = new javax.faces.model.SelectItem(element.getId(),element.getValue());
| retVal.add(item);
| }
| return retVal;
I'll keep thinking/searching/...

Can you describe what you're trying to do? I have a JBoss instance deployed taking all the defaults and *-ds.xml files deploy without problem?
In Response To:
Ok - so if that is correct (which I think today I proved), I cannot use the -dx.xml file to resolve my JNDI/JDBC connection pool because I can only use the Tomcat only configuration of JBoss.
If I do not put the -dx.xml file in my deploy folder, JBoss starts but when my application runs I get a "NameNotFoundException" which references "TestWarDB".
For reference...
my web.xml contains:
<resource-ref>
TestDataSource
<res-ref-name>jdbc/TestDataSource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
my jboss-web.xml contains:
<resource-ref>
<res-ref-name>jdbc/TestDataSource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<jndi-name>java:/TestWarDB</jndi-name>
</resource-ref>
So how do I tell JBoss/Tomcat how to resolve java:/TestWarDB?
I have tried configuring Tomcat (the version deployed within JBoss) according to Tomcat's documentation but I have had no luck in getting anything to work. If JBoss has a Tomcat Only installation configuration, I cannot possible think this would not support interaction with a database.
