Subject RE: Cocoon Database samples not working?
Date Mon, 11 Aug 2003 06:14:30 GMT
Thanks for the reply.  I am not sure what JDBC jar
is required here... AFAIK, the Cocoon samples (the
one for HSQL) should work "out the box" with no
additional files or configuration entries required 
(and, yes, for the record, I did jump through all 
the hoops trying to get Cocoon to talk to mySQL -
using the same - working - setup as another 
machine that was working under JDK1.3... but this 
is all moot - the Cocoon samples should work!)

Hi Derek,
I've had no problem with databases at all with 2.0.4 and Java 1.4.
Did you copy your jdbc jar file to the WEB-INF/lib folder of Cocoon (if it was a new installation)
and did you add the appropriate entries to the cocoon.xconf and web.xml files?
I don't want to sound as though I'm stating the obvious but its caught me out a few times!

I definitely downloaded and used the JDK1.4 compatible
version - that is why I was surprised it wasn't working.
As I said, I have used 2.0.4 with JDK1.3 without any
problems - but I need to upgrade to 1.4 for other apps -
I cannot do so if Cocoon does not work properly.
Are there any pacthes or solutions for this problem?
Should I alert on of the developers?

Make sure that the version of cocoon you are running is build with JDK 
1.4 if you are running on JDK 1.4. There was (no longer true in 2.1) a 
jvm version dependency because of changes in JDBC between the versions.
