Tomcat version - 4.1.12 MySQL version - 3.23.55-nt OS - WinNT JDK - 1.4.1_01
I have researched this problem on the internet and in the documentation for Tomcat, and I still haven't resolved this issue. So, I'm looking for help from someone from this list. Here is my URL that I invoke: http://localhost:8080/dbtest/test.jsp Here is the error I receive: java.sql.SQLException: Cannot load JDBC driver class 'null' at org.apache.commons.dbcp.BasicDataSource.createDataSource(BasicDataSou rce.java:529) Referencing this URL - http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html: 1. I have a database and table with 1 row of data 2. Here is the chunk of code that I inserted into my $CATALINA_HOME/conf/server.xml. <!-- Database configuration for MySQL --> <Context path="/DBTest" docBase="DBTest" debug="5" reloadable="true" crossContext="true"> <Logger className="org.apache.catalina.logger.FileLogger" prefix="localhost_DBTest_log." suffix=".txt" timestamp="true"/> <Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"/> <ResourceParams name="jdbc/TestDB"> <parameter> <name>factory</name> <value>org.apache.commons.dbcp.BasicDataSourceFactory</value> </parameter> <!-- Maximum number of dB connections in pool.

Set to 0 for no limit. --> <parameter> <name>maxIdle</name> <value>30</value> </parameter> <!-- Maximum time to wait for a dB connection to become available in ms, in this example 10 seconds.

Here is my web.xml under $CATALINA_HOME/webapps/dbtest/web-inf/web.xml: <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd";> <web-app> <description>MySQL Test App</description> <resource-ref> <description>DB Connection</description> <res-ref-name>jdbc/TestDB</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> </web-app> 4. Added my DB Driver under $CATALINA_HOME/webapps/dbtest/lib/org/git/mm/mysql/Driver.class. I also tried just putting the jar file under the /lib. 5. Created a JSP and class just like in the example above. I just changed my select statement inside the class, that's all. 6. I have verified that my database is indeed running. 7. In my.ini (for MySQL), the port setting is NOT commented. The bind-address IS commented out. Thanks for any help!
