Has jboss not "loaded" paypal_stubs.jar before jboss-seam.jar does its component scan? Any workarounds known? I thought all of the third party jars should go right at the top of the .ejb file, right where seam, facelets, etc jars are.

Here's a trick you can try. Go to deploy\jbossweb-tomcat55.sar\META-INF\jboss-service.xml
set true
Often, the problem is that something packaged at the EJB or EAR level references something packaged in the WAR. With the Tomcat classloader, this won't work. (WAR classes can reference EJB classes, but the converse is not true). When using the JBoss classloader for WARs, any class can generally reference any other class.
Exceptions to the above have to do with repository configuration. See http://www.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration
For a general checklist that helps to debug NoClassDefFoundError, see http://wiki.jboss.org/wiki/Wiki.jsp?page=GetClassNotFoundExceptionOrNoCla...

[JBoss Seam] - Re: Class loading problem

Hi. I'm getting a similar error. In my case an interface of mine cannot be found. The error seems random such that if I just redeploy, the error goes away. This used to work... I'm using Seam from CVS.
Is Seam errantly tring to load interfaces and abstract classes as classes?
My stack trace is below. Does anybody have an idea of what is happening?

[JBoss Seam] - The pageflow attribute of @Begin not always processed proper
by rlhr
I defined a SFSB as follow:
@Stateful
| @Name("someAction")
| public class SomeAction implements Some {
|
| public void testOne() {
| this.delegate();
| }
|
| @Begin(id="MY_ID", pageflow="testflow")
| public void delegate() {
| }
| }
|
In a jsp, if the action of a button is set to #{someAction.testOne}, something goes wrong and the flow doesn't start. The current page is reloaded.
If the button action is set to #{someAction.delegate}, then the flow starts properly.
Now if I do the following, it works fine as well:
@Stateful
| @Name("someAction")
| public class SomeAction implements Some {
|
| public void testOne() {
| this.delegate();
| }
|
| @Begin(id="MY_ID")
| public void delegate() {
| Pageflow.instance().begin("testflow");
| }
| }
|
So it seems that when a method of the SFSB call the delegate method, the pageflow attribute of the @Begin annotation is not processed properly.
Unless I'm not supposed to do what I'm doing (But I need to perform some check before starting the flow or not), I believe this could be a bug.
I hope this can help.
