Christoph Dittberner commented on CAMEL-2663:
---------------------------------------------
A camel-eclipse package sounds very well.
My plugin depends on
org.eclipse.osgi,
org.eclipse.equinox.app,
To use the FileLocator.convert-methode 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.

> Key: CAMEL-2663
> URL: https://issues.apache.org/activemq/browse/CAMEL-2663
> Project: Apache Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.2.0
> Environment: Windows, Eclipse 3.5.2
> Reporter: Christoph Dittberner
> Assignee: Willem Jiang
> 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)
