Thanks Marius,
yes I already found out about the .gwtrpc filter and this is working fine,
also I was already able to lookup other components, including the Execution
component, where, I just found out, I can
XWikiContext xwikicontext =
(XWikiContext)execution.getContext().getProperty("xwikicontext");
XWikiUser user = xwikicontext.getXWikiUser();
if ( user.getUser().equals("XWiki.Guest") ) {
//User is not authenticated
}
in fact I think I was before trying to access the old context as it would be
accessed by old plugins or something like that, I am slowly finding my way
in the new component structure. Thanks for your prompt answer!

P.S. great and smart integration for the gwt servlets!
enough to declare
them as a normal component! Just strange to find the
XWikiRemoteServiceServlet in the wysiwig component.
It's there because:
* it was developed for the WYSIWYG editor which is the only module
relying on it so far and
* it depends on the old XWiki core to lookup components, specifically
com.xpn.xwiki.web.Utils.getComponent(Class), so I couldn't move it to
one of the new component-oriented modules
* I hesitated to move it to the old XWiki core because the current
practice is to move things out of the core not in.
Since you don't have to depend on the WYSIWYG editor module to be able
to use it we can keep it where it is for now.
Thanks,
Marius

First of all, you should know that we have a generic GWT-RPC servlet
which is mapped to all URLs ending with .gwtrpc and which looks up XWiki
components. In other words, you can implement a RemoteService as an
XWiki component without touching the web.xml file (i.e. without adding a
new servlet mapping).
See
http://extensions.xwiki.org/xwiki/bin/view/Extension/Component+Module
for details about XWiki components. You can take as an example
http://svn.xwiki.org/svnroot/xwiki/platform/web/trunk/xwiki-gwt-wysiwyg-cli…
with its implementation
http://svn.xwiki.org/svnroot/xwiki/platform/web/trunk/xwiki-gwt-wysiwyg-ser…
.
If you still want to use your own GWT-RPC servlet then in order to have
the XWiki context initialized you need to map the
XWikiContextInitializationFilter to your servlet. Checkout web.xml to
see what is done for "gwtrpc" servlet.
Hope this helps,
Marius
thanks
