RE: [c2] class loading problem with a jdbc driver
I found that renaming the oracle library so that it ends in ".jar" instead of ".zip" did the trick. ;-) It works well! Thank you for the excellent advice!

RE: [c2] class loading problem with a jdbc driver
Seems to be worked out. I had to place my oracle jar in the ext directory of JRE. A big thank you to the Cocoon 2 bug fixers for solving this problem!

[c2] class loading problem with a jdbc driver
I'm having trouble specifying the classpath for a jdbc driver. Here's the entry in my web.xml file for loading the jdbc driver: load-class oracle.jdbc.driver.OracleDriver org.hsqldb.jdbcDriver I get the following exception first thing (no previous entries in the log file) when I start cocoon. Immediately after the (long) load class exception, the log file prints out the full classpath including the jdbc driver (it's "/opt/jakarta-tomcat-4.0-b5/webapps/cocoon/WEB-INF/lib/classes12.zip"). Why isn't the class being found (it gets found later when I load relevant esql-based xsp pages)? What am I doing wrong?
