Claus Ibsen commented on CAMEL-2663:
------------------------------------
Its based on EPL license, which is in B category
http://www.apache.org/legal/3party.html
However the source code where its being used will be minimal and with really
very very low change some end user will derive this work without knowing the
license implications by Eclipse.
And the jar is
http://repo1.maven.org/maven2/org/eclipse/equinox/common/3.3.0-v20070426/common-3.3.0-v20070426.pom
Which is in central maven repo, so it may be doable.

> 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)
