DefaultPackageScanClassResolver can't read entries in an eclipse rcp app
because it can't handle bundleresource - protocol

----------------------------------------------------------------------
A camel-eclipse package sounds very well.
My plugin depends on
org.eclipse.osgi,
org.eclipse.equinox.app,
To use the FileLocator.convert-method I had to depend on org.eclipse.equinox.common,
These are the libs I included in my plugin:
camel-core-2.2.0.jar
camel-spring-2.2.0.jar
camel-spring-integration-2.2.0.jar
commons-management-1.0.jar
camel-mail-2.2.0.jar
mail.jar
spring.jar
spring.jar is the complete spring-framework-2.5.6 package.

> Project: Apache Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.2.0
> Environment: Windows, Eclipse 3.5.2
> Reporter: Christoph Dittberner

> Attachments: EclipsePackageScanClassResolver.java

> scenario:
> I have an eclipse rcp based app and use the apache camel libs within my plugin, i.e. the libs are one classpath of the plugin. I use a route using camel-mail to process some mailqueues.
> CamelContext context = new DefaultCamelContext();
> context.addRoutes(new RouteBuilder() {
> public void configure() {
> from("imaps://mailserver?username=user&password=password&consumer.delay=5000&delete=false&unseen=true")
> .to("log: new mail");
> }});
> context.start();
> When I start my app all seems to be ok. But in my log I get a lot of error messages regarding the loading of converters. If I ask my context to find a converter f.i. to converty to byte[] form inputstream (as I did see in another mail example reagding attachments) I get null because the context can't find one.
> I debugged deeper into the camel code and it seems that the DefaultPackageScanClassResolver can't load from urls starting with bundleresource like "bundleresource://109.fwk32380043:4/org/apache/camel/component/file/"
> using camel-osgi didn't worked because all camel libs are loaded as inner libs of my single plugin and not as plugins. (loading as plugins didn't worked but thats another problem/bug)
