Subject RE: java.lang.RuntimeException: Could not get the datasource
Date Mon, 01 Aug 2005 17:50:51 GMT

I found more information in the core.log file.

How can I fix this error?

Subject: java.lang.RuntimeException: Could not get the datasource



I inherited a Cocoon application that was written by another developer.

The developer left our company and nobody has touched this application 
in 2 years.

The application uses cocoon-2.0.3.jar and runs on JDK 1.3.1

The application connects to an Oracle database and an Informix database.

The driver jar files are located in WEB-INF/lib and I am using the
"load-class" parameter in the web.xml file.

When I try to browse one of the pages in the application, I observe 
a NoValidConnectionException.

How can I troubleshoot this?

It appears that the NoValidConnectionException 
is thrown in
org.apache.avalon.excalibur.datasource.JdbcConnectionFactory

I downloaded the source code for JdbcConnectionFactory from apache.org 
but the source file / line numbers do not appear to match the line
numbers 
in the jar that I am using.

WEB-INF/lib contains this file:  avalon-excalibur-vm12-20020705.jar

This appears to be a custom-built jar. 

(Another roadblock is the LogKit framework.  This application uses
LogKit but I am having trouble finding suitable documentation for LogKit
configuration. I want to be able to enable full DEBUG output for all
logger's.)

Here's the full stack trace:
