Hi all,
first of all, thanks for the great work, xwiki is a great product
i'm trying to integrate the rendering component of xwiki into our
application for hours, without success.
I included all the libraries from XWiki 2.0 M4 and was running
following code in a standalone application (not within servlet
container, but thats no problem?)
--
EmbeddableComponentManager componentManager = new  
EmbeddableComponentManager();
componentManager.initialize(this.getClass().getClassLoader());
Parser parser = (Parser)componentManager.lookup(Parser.class,  
Syntax.XWIKI_2_0.toIdString());
XDOM xdom = parser.parse(new StringReader("test"));
// Generate XHTML
PrintRendererFactory rf =  
componentManager.lookup(PrintRendererFactory.class,  
Syntax.XHTML_1_0.toIdString());
DefaultWikiPrinter printer = new DefaultWikiPrinter();
Renderer htmlRenderer = rf.createRenderer(printer);
// Perform the rendering - the exception is raised here
xdom.traverse(htmlRenderer);
--
The stacktrace is attached below. The DocumentAccessBridge component
cannot be loaded. I tried to figure out what is going on and debugged
around. The loop that loads all descriptors for xwiki components
doesnt include DocumentAccessBridge. There is no
META-INF/components.txt in the xwiki-core-bridge-2.0-milestone-4.jar
and no class in this library has the @Component annotation.
I just cannot figure out what is going wrong. Different parsers and
printrenderers (other than XWIKI_2_0 and XHTML_1_0) as the use of the
Converter instead of Parser produce the same result.
What am i doing wrong? Any help would be really appreciated.
Hmm this is strange. DocumentAccessBridge is not required in  
standalone mode.

I've just built the rendering standalone module at:
http://svn.xwiki.org/svnroot/xwiki/platform/core/trunk/xwiki-rendering/xwiki...

It has some tests in
http://svn.xwiki.org/svnroot/xwiki/platform/core/trunk/xwiki-rendering/xwiki...

It builds fine.

Can you show me the xwiki dependencies you have added to your project?

My take is that you've added the xwiki-core-rendering-xwiki module  
dependency. If so you need to remove it since it's for using the  
rendering module inside of xwiki.

Let me know. I'm keen to get this working perfectly well.

Thanks
