I'm not certain but don't think that it's the only difference. It should be the only different jar in the lib directory - but at various points there has been conditional compilation in the cocoon classes themselves. It wasn't always so, and I don't think it's so now (in 2.1 HEAD). If you're curious though, I'd love to find out what happens if you take that route!

No valid JdbcConnection class available with MySQL
I'm just getting started with Cocoon and trying to get the database connectivity part working with MySQL. I set up the database, set up the configurations in web.xml and cocoon.conf and installed the MySQL driver, but when I try to run it I get the following error: org.apache.cocoon.ProcessingException: Exception in ServerPagesGenerator.generate(): java.lang.RuntimeException: Could not get the datasource org.apache.avalon.excalibur.datasource.NoValidConnectionException: No valid JdbcConnection class available I do have the driver in the WEB-INF/lib folder. I've tried two different versions (mm.mysql-2.0.12-bin.jar and mysql-connector-java-3.0.6-stable-bin.jar), both of which work with other Tomcat webapps on the same machine. I have also checked to see if there is a JdbcConnection class in the classpath, and found it to be in the same jar file as the NoValidConnectionException class that is returning the error, so I really can't see how the JdbcConnection class could be unavailable. If I enter the wrong password in the datasource description in cocoon.xconf, I get an Invalid authorization specification error instead. It seems to me that in order to get this type of error, cocoon must be talking to the database, but that would be impossible if it had no valid JdbcConnection class, right? Or am I misunderstanding how these things work? I'm running this on Mac OS X, 10.2.6, JDK 1.4.1, MySQL 4.0.12, Cocoon 2.0.4, Tomcat 4.1.18, Apache 1.3.27. -- Austin Money isn't the most important thing in the world, but it's way ahead of whatever's in third. --Dick Messenger - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: No valid JdbcConnection class available with MySQL
check through the logs in WEB-INF/logs and the tomcat logs as well for errors reported in instantiating the connection at startup. Typically this problem has come down to one of the following: - permissions in mysql (is your user permitted to connect from localhost/ip?) - the driver not being declared in web.xml - using cocoon built with jdk1.2/1.3 with jdk1.4 or vice versa - something else that escapes me Any of that help?
