Folks:
I've been trying to install Xwiki on a Suse 10.2 linux
distribution with apache-tomcat-6.0.16 and MySQL
5.0.26 (the jdbc driver is
mysql-connector-java-5.0.8.jar).
With either Xwiki 1.2.2 or 1.3.rc1 i get a null
pointer exception when I get to the XWikiPreferences
page i.e.
http://localhost:8080/xwiki/bin/objectadd/XWiki/XWikiPreferences?classname=…
for 1.2.2. Using 1.3 the error is terminal (no way to
recover). Using 1.2.2 if I click on the
XWikiPreferences header then I see a normal page,
instead of the exception trace. Except, if I try,
say, to save a comment, I get another trace.
This is my JRE:
java -version
$java version "1.5.0_08"
Java(TM) 2 Runtime Environment, Standard Edition
(build 1.5.0_08-b03)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_08-b03,
mixed mode)
this is the second trace:

Caused by: java.lang.NullPointerException
I browsed the various resources, but the only null
pointer I found was wrt a totally unrelated
circumstances.
Any kind soul can please tell me what is the gripe
about?
Cheers,
