Claus Ibsen commented on CAMEL-1035:
------------------------------------
Well the DefaultClassLoader is OSGi aware but it doesnt expose getBundle or any
methods to get hold of the OSGI API where we can find entries using the
existing OSGi resolver code in Camel

> 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.

> 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.
