Hi, while I tried to implement the org.xwiki.classloader.ExtendedURLStreamHandler in the described way I recognized some problems:
- First, the class org.xwiki.rendering.internal.macro.script.ScriptClassLoaderHandlerListener uses the org.xwiki.rendering.internal.macro.script.AttachmentClassLoaderFactory which only constructs AttachmentClassLoaders which uses org.xwiki.classloader.internal.protocol.attachmentjar.AttachmentURLStreamHandler. Last one cannot be exchanged. In the current implementation this is no problem because the ScriptMacro only supports the protocol “attach” and the URL Format itself. The AttachmentURLStreamHandler can handle this. I think the Used ClassLoaderFactory should automatically get the right Class Loader depending on the used protocol. - Second, I also have to resolve the dependencies of the given maven artifact in the URL. So I have to put more than one jar-URL in the URL Connection. Otherwise I have to declare all the dependencies in the URL String. Do you know a solution for my problems?

See http://extensions.xwiki.org/xwiki/bin/view/Extension/ClassLoader+API#HAddinganewURLStreamHandler Thanks -Vincent PS1: You should checkout OPS4J Pax URL: https://ops4j1.jira.com/wiki/display/paxurl/Mvn+Protocol PS2: I think we would be interested by such a contribution. Actually a great contribution would be to bridge our code to use PAX URL (not even sure anything is needed for that!). We probably just need a tutorial explaining how to use PAX URL in XWiki. _______________________________________________ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
