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

Hi,
The scrollable box uggh i which you display code snippets is never as wide
as its containing box and thus usually has both horizontal and vertical
scroll bars uggh. This is very bad ui design. Code is impossible to read
easily and the select and copy. Scroll bars should be avoided whenever
possible.
WDYT?

Hi,
Thanks for the compliments on xwiki ! Well, database porting should be
discussed on the developers list (
http://forge.objectweb.org/mail/?group_id=170 ) and added to the xwiki
page on databases (
http://www.xwiki.org/xwiki/bin/view/Dev/Database+Porting )
Concerning your errors, it doesn't look good.. it seems hibernate is
chocking while looking at the capabilities of the DB2 driver.. However
when I look at this (
http://www-128.ibm.com/developerworks/db2/library/techarticle/0306bhogal/03…
) it seems it should work.
Maybe it fails on something specific in the mapping.. So you might want
to remove each column from the xwiki.hbm.xml file until it works to see
what is the cause. Maybe a simple change in the mapping can make it work
with B2 without breaking xwiki..
