ClassLoader cannot find xhtml files when scanning page.xml files in an EAR with Multiple
WARs
---------------------------------------------------------------------------------------------
Key: JBSEAM-3849
URL: https://jira.jboss.org/jira/browse/JBSEAM-3849
Project: Seam
Issue Type: Bug
Affects Versions: 2.1.1.CR2
Environment: JBoss AS 5.0.0.GA, JDK6, Seam 2.1.1.CR2
Reporter: Reind D
I have an EAR that contains multiple WAR files. The ear deploys correctly, but on the
first web request, during a scan of all *.page.xml files, I get the following output to
the log for each page.xml file:
WARN [VFSScanner] Error handling item 'login/index.page.xml':
java.lang.NullPointerException: Cannot find URL from classLoader for login/index.page.xml,
loading from org.jboss.web.tomcat.service.WebCtxLoader$ENCLoader@1ed964f
The NPE occurs in this code:
org.jboss.seam.deployment.FileDescriptor.java
this.url = classLoader.getResource(name);
if (this.url == null)
{
throw new NullPointerException("Cannot find URL from classLoader for " + name
+ ", loading from " + classLoader);
}
As a result, none of the page.xml files work.
Note that the second WAR works as expected, with all the page.xml files loaded correctly.
The same project worked in Seam 2.0.2.SP1 and JBoss AS 4.2.3.GA

Reind D commented on JBSEAM-3849:
---------------------------------
A possible cause of this bug:
The page.xml files are looked up in:
FileDescriptor:30
this.url = Resources.getResource(name, ServletLifecycle.getServletContext())
ServletLifecycle.ServletContext returns a static ServletContext object that is initialized
in ServletLifecycle.beginApplication(ServletContext context)
The last call to ServletLifecycle.beginApplication() will overwrite the ServletContext
object returned in ServletLifecycle.getServletContext() and used by FileDescriptor.
Therefore, the 1st WAR will try to load resources using the 2nd WAR's ServletContext.
Obviously, it won't be able to find the file since it's looking in the wrong
WAR's context.

----------------------------------------
The named WAR patch I attached to JBSEAM-3119 will fix this. Pretty much all the multi war
issues revolve around the statics in ServletLifecycle and Lifecycle.

Reind D reopened JBSEAM-3849:
-----------------------------
The related Multi-war issues may be resolved, but this one is still occurring.
I just checked out the latest version from
http://anonsvn.jboss.org/repos/seam/branches/community/Seam_2_2 and FileDescriptor.java is
still calling:
Resources.getResource(name, ServletLifecycle.getServletContext());
Which returns a static reference to the ServletContext which is overwritten by the last
webapp to be initialized.
private static ServletContext servletContext;
public static ServletContext getServletContext()
{
//don't throw an exception if null, because of unit tests
return servletContext;
}

Attachment: file-descriptor.diff
I was not sure about the one but there was a comment saying it was fixed so I did not look
to hard.
In FileDescriptor if we change this line:
this.url = Resources.getResource(name, ServletLifecycle.getServletContext());
to this:
this.url = Resources.getResource(name, ServletLifecycle.getCurrentServletContext());
it should work. I have attached a patch, would you be able to try it out Reind? I
don't have a test case to try it on.
