I have a theory on what is happening but I will probably not have time to test it for a
few days. I think that you will only see this behavior when the hot deploy filter is being
used. On startup there should not be a problem because seam apps start up sequentially, so
the correct servlet context should be used each time (This is the reason I did not touch
this file in my original patch, I though it would be ok).
I think the hot deploy filter is being called before the ContextFilter and that is why you
are seeing the problem. I have attached a patch that makes the hot deploy filter run
inside the ContextFilter, if you have time Reind would you be able to see if this fixes
it? If not I will do some testing in the next couple of days.
Classloader cannot find XML files in multiple WARs
--------------------------------------------------
Key: JBSEAM-4316
URL: https://jira.jboss.org/jira/browse/JBSEAM-4316
Project: Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.2.0.CR1
Environment: JBoss AS 5.0.0.GA. Seam 2.2 r11299
Reporter: Reind D
Attachments: pages-fix.diff
I have an EAR that contains multiple WAR files. The first webapp to be accessed works
fine. Any web request to the 2nd WAR to be accessed causes the following error:
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
FileDescriptor.java calls:
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;
}
The 2nd webapp to be initialized will have a reference to the first webapp's
ServletContext.
