Hi all,
I did some digging and discovered a solution to the interaction problems
with Cocoon, JDBC and JRE1.4.0.
The problem lies in the version of Avalon-Excalibur currently packaged
with Cocoon both in release and CVS. The first thing I tried was moving
to the bleeding edge 2.1-dev from CVS but I still had the same JDBC
problems, namely:
org.apache.avalon.excalibur.datasource.NoValidConnectionException: No
valid JdbcConnection class available
So then I tried rebuilding the entire latest Avalon-Excalibur package
from CVS. However, Avalon-Excalibur is in a state of flux (according
to the project webpage) and I ran into some compilation problems
very early on in the build.
However, I was able to build the Avalon Framework and Logkit from CVS.
That was enough to let me build the Avalon-Excalibur-Datasource
package (Datasource is the part of Excalibur that is causing grief
here). I then took the Excalibur jar file currently in Cocoon's CVS
(avalon-excalibur-20020506.jar), replaced the Datasource class files
with those that I just built, rebundled the excalibur jar file and
presto! JDBC works with cocoon and ESQL is working again.
My new excalibur jar file is 343k and _should_ work as a drop-in
replacement for the excalibur jar shipped with 2.0.2+ but I can't
regress back to test with 2.0.2 so I'm leaving that as an exercise for
the reader. The jar is a little large to send to the mailing list
but I'll gladly email a copy to the first 10 people that write me :)
Preferably, a Cocoon maintainer will verify that this is a sensible
thing to do and will update the CVS HEAD accordingly.
Cheers, Jonathan
