Does JBoss support he APP-INF/lib directory?

I am trying to determine if JBoss supports using jars from the APP-INF/lib directory in an ear file. I know this directory is something BEA added into Weblogic and isn't in the spec (unless it has been added within the last year or so), just curious if JBoss supports it

The class loading page of the Wiki is ambiguous:

http://www.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration

The relevant part is this:

The isolated EAR or WAR repository will load its libraries in this order:

1. APP-INF/lib (for EARs) and WEB-INF/lib (for WARs) *Is APP-INF/lib applicable to JBoss? Is that not a weblogic-only construct?

You will notice it says it searches APP-INF/lib but then someone added a comment asking if it is applicable to JBoss...sort of makes the doc ambigious.

I don't believe so. Probably the Wiki should be changed. But new features are added all the time.

The work-around is to modify your .ear file Classpath setting:

JBoss 4.0.5 and earlier do not support it. JBoss 4.2.0 supports it, but it defaults to /lib directory. You can override it by specifying the lib directory of your choice in /META-INF/jboss-app.xml. Here is an example:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE jboss-app
PUBLIC "-//JBoss//DTD J2EE Application 4.2//EN"
"http://www.jboss.org/j2ee/dtd/jboss-app_4_2.dtd"
>
<jboss-app>
<library-directory>APP-INF/lib</library-directory>
</jboss-app>

So where should the shared libs go in ear?

Just to clarify, What should be the location of shared libs inside ear in case of JBoss 4.0.5?

In 4.0.5, as far as I know, shared library jar files need to be listed in application.xml, in which case then can appear anywhere. There is no directory whose jar files are automatically loaded.
