Re: Webdav and restlet
The implementation I referred to in that particular February message was work-for-hire for a proprietary customer. But you might be able to find most of the relevant hints by looking at the DAV 1 implementation with DAV 2 stubs in our GoGoEgo open source project, gogoego.googlecode.com. We have not yet begun to package downloadable releases of GoGoEgo, and the code still needs cleaning and commenting, but you can get all the interesting DAV-related examples from trunk here: http://gogoego.googlecode.com/svn/trunk/modules/RestletFoundation/src/com/solertium/baserestlets/ In VFSResource, Dav1VFSResource, Dav2VFSResource, we are exposing the versioned file system of our CMS, using Restlet resources, in a way that is compatible with MS Web Folders as well as South River Webdrive and wdfs. I use this implementation all day, every day with wdfs to do mission critical work; it's well exercised. You can see in Dav2VFSResource where the lock and unlock support would be if the underlying storage supported locking semantics ... the fact that it's not implemented here isn't Restlet's fault, but GoGoEgo's open source VFS layer doesn't yet support locking. Dav2VFSResource fakes it to keep certain clients happy, notably OS X. You could do this all in a more Restlety way -- especially if you are just working with plain old files and don't need to access a special repository -- but most of what you see here is a port of a port of a port. It does contain all the necessary hints for what MS Web Folders expects to see in its headers, etc. and some ideas of how to glue this to Restlet. The public GoGoEgo repository is licensed under GPL, but if you want us to grant an individual license that is compatible with your own for any portions of this code, just email me personally and we can make arrangements. A final note, see in the comments of Dav1VFSResource that it intentionally violates RFC2518 in two ways that I would recommend preserving -- but if you want an RFC compliant version you must take these violations out. - Rob On Tue, Jun 3, 2008 at 7:48 PM, Jean-Yves Cronier [EMAIL PROTECTED] wrote: Enough workarounds exist that my company's been able to produce a full WebDAV level 2 provider that runs on 1.0/1.1 Where can we find this source code?

RE: Webdav and restlet
Hi Yousef, Based on the stack trace, I tried to lookup the NPE at line 212 in Finder. It doesn't correspond to the latest in SVN trunk nor to the latest in 1.0 branch. Could you test again with the latest version?

I've added a handlePropfind and allowPropfind methods to the resource, and for simplicity, the handlePropfind just print a message to a log file, and the good news is that it reaches the handlePropfind method, and it did print the message, however, it threw an exception in the way back to the caller, here is the exception I got: Feb 7, 2008 9:56:13 AM com.noelios.restlet.StatusFilter doHandle SEVERE: Unhandled exception or error intercepted java.lang.NullPointerException at org.restlet.Finder.allowMethod(Finder.java:212) at org.restlet.Finder.handle(Finder.java:150) at org.restlet.Filter.doHandle(Filter.java:107) at org.restlet.Filter.handle(Filter.java:136) at org.restlet.Router.handle(Router.java:393) at org.restlet.Filter.doHandle(Filter.java:107) at org.restlet.Filter.handle(Filter.java:136) at org.restlet.Filter.doHandle(Filter.java:107) at com.noelios.restlet.StatusFilter.doHandle(StatusFilter.java:87) at org.restlet.Filter.handle(Filter.java:136) at org.restlet.Filter.doHandle(Filter.java:107) at org.restlet.Filter.handle(Filter.java:136) at com.noelios.restlet.application.ApplicationHelper.handle(Appli cationHelper.java:95) at org.restlet.Application.handle(Application.java:266) at org.restlet.Filter.doHandle(Filter.java:107) at org.restlet.Filter.handle(Filter.java:136) at org.restlet.Router.handle(Router.java:393) at org.restlet.Filter.doHandle(Filter.java:107) at org.restlet.Filter.handle(Filter.java:136) at org.restlet.Router.handle(Router.java:393) at org.restlet.Filter.doHandle(Filter.java:107) at com.noelios.restlet.StatusFilter.doHandle(StatusFilter.java:87) at org.restlet.Filter.handle(Filter.java:136) at org.restlet.Filter.doHandle(Filter.java:107) at org.restlet.Filter.handle(Filter.java:136) at com.noelios.restlet.component.ComponentHelper.handle(Component Helper.java:115) at org.restlet.Component.handle(Component.java:230) at org.restlet.Server.handle(Server.java:266) at com.noelios.restlet.ServerHelper.handle(ServerHelper.java:99) at com.noelios.restlet.http.HttpServerHelper.handle(HttpServerHel per.java:87) at com.noelios.restlet.ext.servlet.ServerServlet.service(ServerSe rvlet.java:121) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilt er(ApplicationFilterChain.java:237) at org.apache.catalina.core.ApplicationFilterChain.doFilter(Appli cationFilterChain.java:157) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardW rapperValve.java:214) at org.apache.catalina.core.StandardValveContext.invokeNext(Stand ardValveContext.java:104) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipel ine.java:520) at org.apache.catalina.core.StandardContextValve.invokeInternal(S tandardContextValve.java:198) at org.apache.catalina.core.StandardContextValve.invoke(StandardC ontextValve.java:152) at org.apache.catalina.core.StandardValveContext.invokeNext(Stand ardValveContext.java:104) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipel ine.java:520) at org.apache.catalina.core.StandardHostValve.invoke(StandardHost Valve.java:137) at org.apache.catalina.core.StandardValveContext.invokeNext(Stand ardValveContext.java:104) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReport Valve.java:117) at org.apache.catalina.core.StandardValveContext.invokeNext(Stand ardValveContext.java:102) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipel ine.java:520) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEn gineValve.java:109) at org.apache.catalina.core.StandardValveContext.invokeNext(Stand ardValveContext.java:104) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipel ine.java:520) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:929) at
