Sameer please do *not* reopen old tickets.
Create a new ticket and link to this one.
Reopening old tickets messes with the changelogs and release notes.
And you issue is just a sub issue of this.

> I've encountered a problem with the scanning of jar files with the @Converter annotation if the Jars are loaded with the webstart classloader. Because the URL starts with _http:_ the conversion to a file fails in ResolverUtil.
> I've attached a patch that uses an UrlResource if the url starts with _http:_ and this works if the jar-resource has the version information added to the jar file in the JNLP-file (like <jar href="camel-core-1.4-SNAPSHOT.jar"/>). But if the version is added separately (like <jar href="activemq-core.jar" version="5.1.0"/>) it fails because the classloader returns the name of the jar-file without the version information (like http://....../activemq-core.jar) and this file does not exist.
> I'm currently trying if it is possible to check whether the application is started via webstart (there is a class Tool that should only exist in the webstart classloader) and in this case I'll check if the filename of the jar-file is returned correctly. If yes maybe we can provide another patch to get rid of the problem described above.
