[xwiki-devs] Downloading from SVN repository..

Hello Devs, This is regarding the SVN integration with XWiki, about which I had been asking a lot of questions in the past. So, now we have an applet that helps users browse throught their filesystema nd upload multiple files with in click. the uploaded files are commited to SVN. Also, these files are associated with XWiki objects we created. The next step is, checking out of SVN. The scenario is that the user selects a folder on his local system(working copy) and hits a button that should initiate the ceckout/update from sVN for all the objects that are on that XWiki page. What is the best way to achieve this: 1) Is it possible through Velocity (I am sure not...right?) 2) If I write a JAVA class to do the SVNcheckout, how do I integrate it with XWiki (without messing with the XWiki core...or is that the only way to accomplish this) 3) Write a servlet and use teh macro includeServlet...If yes, then how is this doen..I am not evry sure what are the steps to follow to this. 4) any other method? Any help will be great.. Thanks for all help
