Miguel Ángel Pastor Olivar updated FELIX-3696:
----------------------------------------------
Comment: was deleted
(was: Let me add some more light
The WeppAppClassloader delegates on its parent to load the class
{code}
Resource res = ucp.getResource(path, false); (line 209 on
java.net.URLClassloader)
{code}
The previous line ends up at
{code}
public Resource getResource(String name, boolean check) {
if (DEBUG) {
System.err.println("URLClassPath.getResource(\"" + name + "\")");
}
Loader loader;
for (int i = 0; (loader = getLoader(i)) != null; i++) {
Resource res = loader.getResource(name, check);
if (res != null) {
return res;
}
}
return null;
}
}
{code}
In the previous loop; when the getLoader(i) returns the loader that the
ExtensionManager has already injected into the classloader
(http://felix.extensions:9/) and try to execute the getResourceMethod on that
Loader, I am getting a IllegalArgumentException becuase the name is
"java:org.portletbridge.portlet.BridgeFunctions"
If I disable the embedded OSGI container my code works smoothly (the same code
works if I use Equinox instead of Felix).
I have tried with the trunk version (I have updated my local copy a couple of
hours ago) and I am getting the same error (debugging the source code shows me
the same scenario described in the previous comments)
Thx!)

> Key: FELIX-3696
> URL: https://issues.apache.org/jira/browse/FELIX-3696
> Project: Felix
> Issue Type: Bug
> Affects Versions: framework-4.0.2
> Reporter: Miguel Ángel Pastor Olivar
>
> I am embedding Apache Felix (and Equinox because I would like to switch
> depending on the application server I am running on).
> * The xalan ExtensionHandler executes something like this:
> ObjectFactory.findProviderClass(className, ObjectFactory.findClassLoader(),
> true)
> * The className has the format
> "java:org.portletbridge.portlet.BridgeFunctions" ( I am embedding the OSGI
> container into Liferay portal :) )
> * The extension manager have already added the extension loader to the
> classloader
> {code}
>
> Felix.m_secureAction.addURLToURLClassLoader(Felix.m_secureAction.createURL(Felix.m_secureAction.createURL(null,
> "http:", extensionManager),"http://felix.extensions:9/";,
> extensionManager),Felix.class.getClassLoader());
> {code}
> * When the classloader try to resolve the
> "java:org.portletbridge.portlet.BridgeFunctions" the previous loader added by
> the ExtensionManager cause an unhandled error.
> In sun.misc.URL
> {code}
> public Resource getResource(String name, boolean check) {
> if (DEBUG) {
> System.err.println("URLClassPath.getResource(\"" + name + "\")");
> }
> Loader loader;
> for (int i = 0; (loader = getLoader(i)) != null; i++) {
> Resource res = loader.getResource(name, check);
> if (res != null) {
> return res;
> }
> }
> return null;
> }
> {code}
> In the previous code, the loader injected by the framework is causing an
> IllegalArgumentException here:
> Resource res = loader.getResource(name, check); (instead of returning null)
> Let me know if you need some more details.
