Classloader cannot find XML files in multiple WARs

Environment: JBoss AS 5.0.0.GA. Seam 2.2 r11299
Reporter: Reind D
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,

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.

Reind D commented on JBSEAM-4316:
---------------------------------
Above that should say the *1st* webapp to be initialized will have a reference to the
*second webapp's* webapp's ServletContext.
After trying Stuarts patch to JBSEAM-3849, FileDescriptor's constructor now calls
into:
ServletLifecycle:
public static ServletContext getCurrentServletContext()
{
if (!Contexts.isApplicationContextActive())
{
return servletContext;
}
return (ServletContext) Contexts.getApplicationContext().get(SERVLET_CONTEXT_KEY);
}
But the following conditional evaluates to true and the static servletContext is still
returned.
if (!Contexts.isApplicationContextActive())
In fact, Contexts.isApplicationContextActive() only returns true while the server is
booting. At any other point, during every web request, it always returns false, and the
getCurrentServletContext() ends up returning the static servletContext reference.
The 2nd webapp works fine, the first is obviously broken.

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.

---------------------------------
Hi Stuart. Thanks again, but the patch didn't solve the issue. I'm also not sure
what the consequences are of this bug - whether or not is actually breaking any
functionality (that wasn't already fixed in the other multi-war patch).
I noticed that in order to see these warnings you must set the core:init debug attribute
to true in components.xml
<core:init debug="true" />
I'll attach a small example app that demonstrates this issue.

Stuart Douglas commented on JBSEAM-4316:
----------------------------------------
I had a quick look at the test case. As I thought, it is the hot deploy filter that is
causing the problems, because the application context is not set up when the hot
deployment filter runs.
There are three possible solutions that I can see:
1) Start the application context earlier. I would not recommend this as I have no idea
what side effects this would have.
2) Pass the ServletContext down through the DeploymentHandlers and Scanners into
FileDescriptor. This is probably the most correct solution, but would involve changing
the signature of quite a few classes.
3) Use a quick n dirty ThreadLocal to hold the servlet context that is set by the
HotDeploymentFilter at some point. This seems kind of hackish, but would be the easiest to
implement.

I have done a patch based on approach 2, there was a fair bit more to it that just passing
ServletContext around, this may have to be one for 2.2.1, and just let people know that
hot deployment does not work in multi war projects. The major changes are:
- FileDescriptor now try to get a url from the SerlvetContext before the classLoader, this
is nessesary as some jboss versions will pick up the wrong .page.xml file if there are two
with the same name in different wars.
- The servletContext is passed around through the Scanner and DeplotmentStrategy classes,
any methods/constructors that were changes were kept as delegates to the new method. This
should also fix some potential problems with resources such as remoting and captcha that
could occur in multi war apps.
- I changed the signature of two methods on the ServletLifecycle class (keeping the old
methods as delegates), this was necessary because otherwise the wrong Pages component
could be replaced, so application a would end up with application b's pages.
This patch MAY also fix hot deployment of components in multi war setups, but I have not
tested this.
Reind, would you be able to try this patch out? I am confident that it fixes the original
issue, but I have only had time to test it on the simple test case you provided so I am
not 100% sure there will not be unintended side effects.

Stuart, did you try this out on JBoss 5? IIRC some of those classes are used by the
seam-integration there. We should update that anyway to support your improvements, but
bear in mind that Seam 2.2.1 needs to work on already released versions of JBoss AS.

I tried it out on 5.0.1 and 4.2.3, but only with the example provided, I will hopefully
have time to do more testing in the next couple of days.
I just had a quick look at VFSScanner, and none of these changes should break anything, so
backwards compatibility should not be a problem.

Reind D commented on JBSEAM-4316:
---------------------------------
The patch looks to resolve this issue.
I applied it to seam 2.2 r11312 and tested on jboss-5.0.0.GA.
I performed a test on our (non-trivial) app and everything works as expected.
Thanks Stuart!
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: jbseam-4316.tar.gz, jbseam4316-v1.diff, 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.

Pete Muir updated JBSEAM-4316:
------------------------------
Fix Version/s: 2.2.1.CR1
Great work guys, I set the fix version for 2.2.1 (as 2.2.0 is actually tagged, we are just
waiting on infrastructure to update).
I'm still not sure if we will do a 2.2.1 or whether this ends up moving to 3.0
