Subject [jira] Created: (CAMEL-1035) ResolverUtil under Eclipse RPC (OSGi) error: Could not read entries in url: bundleresource://36/org/apache/camel/converter

ResolverUtil under Eclipse RPC (OSGi) error: Could not read entries in url: bundleresource://36/org/apache/camel/converter
--------------------------------------------------------------------------------------------------------------------------

                 Key: CAMEL-1035
                 URL: https://issues.apache.org/activemq/browse/CAMEL-1035
             Project: Apache Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 1.5.0
            Reporter: Eduard Hildebrandt


Using Apache Camel 1.5-SNAPSHOT with Eclipse RCP 3.x I get a java.io.FileNotFoundException
on loading the converters (see stacktrace below). 
It seems that issue CAMEL-774 is not fixed. 

I tried to debug the source code: 

--- SOURCE: ResolverUtil.java ---- 

            Method mth = loader.getClass().getMethod("getBundle", new Class[] {}); 
            if (mth != null) { 
                // it's osgi bundle class loader, so we need to load implementation in bundles

                if (LOG.isDebugEnabled()) { 
                    LOG.debug("Loading from osgi buindle using classloader: " + loader); 
                } 
                loadImplementationsInBundle(test, packageName, loader, mth); 
                return; 
            } 

--- END SOURCE --- 

"loader.getClass().getMethod("getBundle", new Class[] {});" returns null because the loader
is of type "org.eclipse.core.runtime.internal.adaptor.ContextFinder" and does not have a "getBundle"
method.

Please see discussion at: http://www.nabble.com/ResolverUtil-under-Eclipse-RPC-(OSGi)-error%3A-Could-not-read-entries-in-url%3A-bundleresource%3A--36-org-apache-camel-converter-to20205017s22882.html

Sample project can be downloaded at: http://www.fastshare.org/download/eclipse_camel_test.zip

Unzip the project and import it to you Eclipse Workspace.
You have to use Eclipse because it's an Eclipse plugin.

Instructions to start the project:
1.	Download, unzip and start an ActiveMQ server.
2.	Run "ServiceServer" as "Java-Application".
3.	Open plugin.xml and click on "Launch an Eclipse Application";
4.	A new Eclipse instance will be start. Select "Sample Menu"  "Sample Action" in the new
Eclipse window.
5.	Check the errors in the console view.
