Add support for jndi URL type

[GoogleCodeExporter]

Would be nice to support jndi URL type in Reflections.

You get jndi URL for example when you ask the Servlet for a resource coming 
from the current war/webapp in which you can find the same kind of data than in 
a jar (classes, etc.) and that you may want to scan for the same reasons.

I'm not sure it should be added to the default url types. 
anyway, is this working?

Vfs.addDefaultURLTypes(
                new Vfs.UrlType() {
                    public boolean matches(URL url) {
                        return url.getProtocol().equals("jndi");
                    }

                    public Vfs.Dir createDir(URL url) throws Exception {
                        return DefaultUrlTypes.jarUrl.createDir(url);
                    }
                });

This is not going to work since it does not look anything like a jar URL, you 
get something like jndi://localhost/xwiki/ (where "xwiki" is the context root 
of the application). I need to check exactly how it's possible to scan file 
from a jndi URL.

oh sure it doesn't... I'll look into it when I got the time. 
If you can provide integration instruction, it would be great (something like 
http://code.google.com/p/reflections/wiki/JBossIntegration)

Hmm not sure, I'm debugging Tomcat for my tests currently. Will see if I can 
find something nicer for unit tests.

simple-jndi (http://code.google.com/p/osjava/wiki/SimpleJNDI) sounds good. Plus 
it's on maven central.

BTW my real use case is to scan the WAR I'm running in. Maybe there is another 
way.

Hello, I'm studying the same use case - scanning the WAR I'm running in for 
annotated classes, and don't know how to use the jndi URL returned by a 
ServletContext.

Were you able to solve this, and if so do you have any suggestions ?

Thanks,
David

I tried to look around on how to deal with theses JNDI URLs but could not make 
anything work. I finally put some information in the MANIFEST.mf file to help 
me find what I was searching for. Works for my specific use case but you can't 
always do that...

Thanks for your reply.  I'm not happy with my current scheme, but I seem to 
have gotten it working (for now, in JBoss AS7).  

Given a ServletContext "context":

1. Build a list of URLs with context.getResource(path) for each path returned 
in context.getResourcePaths("/").  This results in two "virtual paths" for 
resources of this war.  These paths include the virtual-server name (defaults 
to "default-host") from standalone-xml.full.

2. For each virtual path,  strip off everything but the last path component 
("META-INF" and "WEB-INF") and use context.getRealPath() on that string to get 
the actual path, e.g. 
"/opt/jboss/standalone/tmp/vfs/tempf981207421a1bc0e/content-cccac5e9cf992bde/MET
A-INF"

3.  search those directories for .jar/.class files.

[I'm using Annovention for annotation discovery - this is a small tweak to the 
com.impetus.annovention.Discoverer.getResourceIterator() method.]

Is this supposed to work on 0.9.9-RC1 or still in trunk ?
