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.
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.

You should be able to check the xwiki log files to provide the full stack trace.
Thanks

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
-Vincent
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.

Uh, oh, this looks like this problem reported last year:
http://markmail.org/thread/4iigsjpxdaw2qzzq
the issue went away there when using mySQL - for unknown reasons, so that time we did not
really find a solution.
hope we can do better this time.

Yes, i read that thread till the end but didn't tried MySql. I tried H2 to be sure if
it's database related issue but same stack trace. I am planning to use that wiki in
our server environment. We use weblogic as application server and Oracle11g as database
server. Actually, after i test standalone version in my desktop, i tried to deploy xwiki
to weblogic and had several errors. I passed all of them and stucked at this one. After
that i gave a try to Apache Tomcat and same issue. I am trying to make it work for a week
but i am desperate now. I think, i will use standalone version at the production
environment :)

Hi,
I found the reason. It's all beacause ojdbc6.jar. There are different jars for every
different minor version change. I used jdbc connector for Oracle 11g ( 11.2.0.4.0 ) and my
database version is 11.2.0.1.0. After i download correct one, problem solved. One thing
to remember is Oracle named all of them as ojdbc6.jar.
Thanks all.
