Subject [jira] Commented: (CAMEL-1035) ResolverUtil under Eclipse RPC (OSGi) error: Could not read entries in url: bundleresource://36/org/apache/camel/converter
Date Thu, 30 Oct 2008 11:01:08 GMT

    [ https://issues.apache.org/activemq/browse/CAMEL-1035?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=46911#action_46911
] 

Claus Ibsen commented on CAMEL-1035:
------------------------------------

I think a workaround is to register the needed type converters manually.

If you can get hold of DefaultTypeConverter there is an addTypeConverter() method.
But of course it would be great if the annotation based classloading works as well.

I have this Eclipse:
Version: 3.3.0
Build id: I20070621-1340

Do I need to download any other Eclipse stuff to get working, or is all the needed .jars in
the .zip project?

> "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.
