Hi all, (This is not IDEA marketing ;))
I installed IDEA version 5 and it seems it has very good integrated support for SVN. You can do update, commit and most of the other stuff within IDEA itself without using Tortoise SVN or anything. The cool thing I found was that, when you move a class from one place to another, earlier we had to manually delete and add it to SVN. Now IDEA does this itself, which is pretty much cool, at least for me :). In case if you don't know, IDEA gives free licenses for open source development and Axis2 is recognized as a project for them.
