 Hi,
 I am trying to deploy production version( .war deployment ) of XWIKI to Oracle11g and
Tomcat environment. I tried every version of xwiki with different versions of Tomcat.  It
deploys the application succesfully but when i request 
http://localhost:8080/xwiki keep
getting
 "NullPointerException at HqlSqlWalker.lookupProperty( HqlSqlWalker.java:560)"
error. As far as i see, tables are created at the database but i cant pass this error.
You should be able to check the xwiki log files to provide the full stack trace.
Thanks

  I also tried with tomcat and h2 database to check
whether it's database related issue and same stack trace.
 I also tried with Weblogic 11g application server and Oracle 11g database and same stack
trace.
 P.S: I could run standalone version.
