Re: [xwiki-users] NullPointerException at HqlSqlWalker.lookupProperty( HqlSqlWalker.java:560)

2016-06-30 Thread Kemalettin OCAK 
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.

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 :)
