Hi,
I have just been trying to set up Roller 2.0 on a Windows XP system
using
Sun's JDK 5, Tomcat 5.5 and DB2 UDB version 8 (with the
COM.ibm.db2.jdbc.app.DB2Driver)...
There have been a few hiccups along the way, and I have been able
to resolve
most of them - but now I think I might have found a problem. I am
getting a
DB error in the roller log (see the error/stacktrace at end of this
email).
After some digging around, it appears that problem is related to a DB2
specific query in the HibernateRefererManagerImpl class. I played
around
with the SQL query a bit and got it working - at least at the DB2
console.
Looking in the subversion history for this class I noticed that the
last
revision of this class made a small change related to the query
that is
producing the error: (
http://svn.apache.org/viewcvs.cgi/incubator/roller/trunk/src/org/
roller/business/hibernate/HibernateRefererManagerImpl.java?
rev=345486&r1=332312&r2=345486&diff_format=h
)
If I use the previous version of that query(from the DB2 console),
everything seems OK. So I guess I am just wondering why that
particular
change was made? Is it something to do with the version of DB2 or
the driver
that I am using? or is there something else that I am missing...
thanks,
Jeff
