back port fix from JBSEAM-4316-Classloader cannot find XML files in multiple WARs
---------------------------------------------------------------------------------
Key: JBSEAM-4620
URL:
https://jira.jboss.org/jira/browse/JBSEAM-4620
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
Assignee: Marek Novotny
Fix For: 2.2.1.CR1
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.
