What are the problems with JDK 1.4?
Hi,
for the next release (2.0.3) we should try to fix the problems concerning
JDK 1.4. One problem, the building of the javadocs is solved now.
But it seems that there are problems with JDBC Pooling. If I compile
everything using JDK 1.4, the sql examples run well. Running this with JDK
1.4, the hsqldb is throwing an exception:
java.sql.SQLException: Connection is broken: Connection refused: connect

org.apache.avalon.excalibur.datasource.JdbcConnectionFactory.<init>(J

Is this a problem with hsqldb? Are other dbs working?

Hi,
I've been playing with Cocoon 2 for a while now in my spare time, it's
quite a piece of work, guys! Anyhow, even using the latest source from CVS
with JDK1.3 the JDBC Pooling seems to have some strange behaviour when more
than 1 datasource is involved.
If I add another jdbc datasource to the cocoon.xconf file, (in my example
I added a mysql database, using the latest mm Mysql driver) cocoon seems to be
confused about which database to use when i go to the forms/employee database
example. If I remove the new datasource, it works fine. The same problem
exists on a page that I write that uses the new datasource - for now my
workaround was simply to do away with HSQLdb, but I thought I might mention it
- I would have thought multiple sources ought to be possible.
