I've written a Web app that works fine under Tomcat 4.1.24. It uses an app-specific Context to set up a JNDI data source that works fine. It uses the org.apache.commons.dbcp.BasicDataSourceFactory and the Oracle 9.2 JDBC type IV thin driver. The Oracle JDBC driver JAR is in TOMCAT_HOME/common/lib; all other JARs are in the WEB-INF/lib directory inside the deployed WAR.
A vendor has shipped s'ware to me that has been tested under Tomcat 4.0.6. The vendor won't guarantee proper operation under 4.1.24, because it hasn't been tested there.
I downloaded 4.0.6, installed it on my machine, put my app WAR in TOMCAT_HOME/webapps, and put the <Context> into the server.xml. The Oracle JDBC JARs are in TOMCAT_HOME/common/lib. I checked the resources page to make sure that my Context from 4.1.24 was okay for 4.0.6. There were no errors in the log file when I started up the app. The XML parser accepted the server.xml without a problem. I got the app log file that I asked for, and I can see debug info from my front controller servlet being written to it.
However, as soon as it tries to access the database I get a "DataSource invalid - no suitable driver" error.
Everything that I gave to 4.0.6 works perfectly under 4.1.24. What common error causes this? I scanned the Archive link from the mailing list page, but nothing suitable appeared. Thanks - MOD
