Custom WebDAV servlet
Hi to everyone,
I'm developing a Java Servlet which should give the ability to
interact via WebDAV with a Subversion repository. The problem is that
the framework is quite complex and I got lost.
I've successfully subclassed the SimpleWebdavServlet class and I'm
able to create a TransientRepository (using a XML configuration file).
I've also started to work on a custom FileSystem, but I'm quite unsure
which components I've to "touch" in order to get everything working
correctly.
I've the need to create a "virtual" filesystem (based on some
temporary property of the Subversion repository) and the only data
source for the data should be the repository itself.
I hope someone can give me some hints.
Thanks in advance,
Daniel

Hi,

Yes, it could be an indication that sessions are opened but never
closed. Is there an easy way for you to check if this is the case?

Yes. It will use more memory than really required, and it will slow
things down at some point.

CacheManager resizeAll

Hi All,
Dec 3, 2007 5:48:52 AM org.apache.jackrabbit.core.state.CacheManager
resizeAll INFO: resizeAll size=4
Dec 5, 2007 2:28:05 PM org.apache.jackrabbit.core.state.CacheManager
resizeAll INFO: resizeAll size=8086
This size is keep on increasing while starting the server size is 4, now
(in two days) is :8086.
Is there any issue in application? Is this lead to any performance
issue?
Best Regards,
RK

it helps a lot, I'll dig into the structure of Jackrabbit and hope to
get it working!
thank you very much for your help ;-)

means: you don't care about the JCR repository, since you want
to use the Subversion repository, right?
in this case i would rather not extend from the SimpleWebdavServlet
but from the AbstractWebDavServlet, since that former already creates
a dependency to JCR by defining that there will be a JCR session.
most certainly don't need that at all.
you will find the AbstractWebDavServlet in the jackrabbit-webdav project
(trunk) or in jackrabbit-jcr-server (in case of an older, released
version). it defines some abstract methods covering the implementation
details:
- factory for the DavResource objects
- factory for the locators
- DavSessionProvider, where DavSession is basically a simple container
to transport lock tokens.
the DavResource is intended to have at least some minimal knowledge
about the underlying repository. so, you will probably have to
define your own implementation (and the corresponding factory).
in case your are coming from slide:
the webdav library present in the jackrabbit project is intended
not to make any assumptions regarding the structure or the nature
of the underlying data storage. this is left to the implementation.
instead they define the functionlity required for the webdav-server.
maybe the code present in the o.a.j.webdav.simple and in o.a.j.server.io
can give you some hints... but i would not try to use it as is,
as long as you don't have a JCR repository underneith.
hope that helps

Hi Angela,
in a more abstract way, I don't really understand how to realize a
WebDAV access, through a servlet, to an already existent
filesystem/storage/database (in this case a Subversion repository).
I've discovered the FileSystem interface, and tried to play a little
with it, but without success.
Best regards,
Daniel

hi daniel
not sure whether i understand your requirements.
can you explain in other words what you want to
achieve?
