Thanks Ludovic, It looks like this error has been fixed, I just updated my copy from the repository and run again. I am getting following messages including error and warnings :

There are 3 warnings and 1 error (all of them seem harmless). Nothing else besides these messages.

You can try fixing it :)
It's a weird hibernate error when changing the unique key of objects from useragent/ip to cookie in the stats module when..

There isn't any other issue. The page shows up; i have tried logging in as admin, adding new users - it works. I will ignore this particular "assertion failure" error message.

thanks,

Log4j is looking to write an xwiki.log file in the current directory.. you must have a permission issue..
You can deactivate this in the log4j.properties file

The rest is non critical (a bug in the stats module).. are you getting any other error when loading the page ? Does the page actually show up ?

Hello, I am working on new xml-rpc apis for p2pxwiki, and am using Eclipse as just my editor (I am not doing any development related to eclipse). I imported the xwiki project in eclipse and used resin to run xwiki locally. I got some errors (most of them "seems" benign, but I wanted to point out anyway incase these will lead to more problems later)

a) Eclipse complained about a missing commons-lang-2.0.jar in the lib directory. I checked the lib directory, it has "commons-lang-2.1.jar" instead. I am not sure why Eclipse is not using the new library. As a fix I downloaded the 2.0 version of commons-lang and put it in the lib directory. It solved this problem.
b) After running xwiki locally, "http://127.0.0.1:8080/xwiki/bin/view/Main/WebHome" pointed to a xwiki document. However, I got few errors on the resin console as follows (the transcript follows below)
Let me know how I can fix these problems. I am using FC4.
Thanks a lot,
-Bikash
