[ http://mc4j.org/jira/browse/STS-397?page=all ]
Jan Moravec updated STS-397:
----------------------------
Attachment: ResolverUtil.java
Patched ResolverUtil.java that successfully discovers action beans located in
utility JARs inside an EAR file deployed under JBoss (4).
> ResolverUtil fails to load action beans outside WEB-INF under JBoss

> Key: STS-397

> Issue Type: Bug
> Affects Versions: Release 1.4.3
> Environment: Windows 2000, JDK 1.5.0.11, JBoss 4.0.2

> I encountered problem with Stripes failing to find action beans located
> outside WEB-INF/class. No exception was thrown, the action beans just were
> not found. After some digging I came to the following conclusion and solution:
> The current dynamic action bean discovery implementation makes use of the
> URLs returned from URLClassLoaders found in the CL hierarchy of the current
> thread context CL. This is an example of the CL hierarchy with dumped URLs of
> the found URLClassLoader instances under JBoss:
> 10:56:43,218 INFO (RMI TCP Connection(3)-192.168.1.65) [STDOUT]
> WebappClassLoader
> delegate: false
> repositories:
> /WEB-INF/classes/

> As one can see, the URLs of EAR's utility JARs are not exposed by JBoss
> org.jboss.mx.loading.UnifiedClassLoader3. And that is even though the UCL is
> a subclass of URLClassLoader! Its getURLs method seems to return an empty
> array.
> One needs to call getClasspath() method on the UCL to obtain the array of
> URLs of JARs inside the deployed EAR. These URLs can then be normally scanned
> for ActionBean instances. I have a patched version of ResolverUtil class that
> seems to work. I will attach it later if I find out how to do that (no file
> upload on this screen).
> Maybe the action bean discovery mechanism should be configurable because you
> may need similar hacks for other application servers....
