Re: 6.0.13 MySQL DBCP Example
To make use a GlobalNamingResources .. /GlobalNamingResources, you'll have to put a ResourceLink element in your webapp's context.xml file. See the end of http://tomcat.apache.org/tomcat-6.0-doc/config/globalresources.html for more information. --David G M wrote: Thanks!

Re: 6.0.13 MySQL DBCP Example
Ok... tomcat 6.0.13 1. I would merge the Context / element from server.xml to your context.xml file and remove the Context element from your server.xml. Placing this element in server.xml is not recommended anymore as it means a restart of tomcat to deploy/undeploy webapps. Also having the Context definition in two places for one webapp will undoubtedly cause problems with one overriding the other. 2. Trim any spaces in the element attributes. I saw an extraneous space in the driverClassName attribute below. 3. It's not recommended you add autoReconnect=true to the mysql db url. It has it's uses, but not in a database pool. Instead, use a validationQuery attribute in your Resource element to test and validate connections before your app borrows them. 4. I'm assuming the mysql-connector-java-*.jar file is stored in the $CATALINA_HOME/lib folder and not present in your webapp's WEB-INF/lib folder. Let us know what happens. If it still doesn't work, let us see the new context.xml file and be sure there isn't a Context ... element in the server.xml. --David G M wrote: I've been trying for days now to establish a jdbc resource for mysql in tomcat 6.0.13 To whom it may correspond: I get the following error Unable to get connection, DataSource invalid: org.apache.tomcat.dbcp.dbcp.SQLNestedException : Cannot create JDBC driver of class '' for connect URL 'null' I have the driver mysql-connector-java-5.0.6-bin.jar copied to $CATALINA_HOME/lib My application web.xml looks like this: (exactly as the example) web-app xmlns=http://java.sun.com/xml/ns/j2ee; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance xsi:schemaLocation=http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd version=2.4 descriptionMySQL Test App/description resource-ref descriptionDB Connection/description res-ref-namejdbc/TestDB/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref /web-app In http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.htmlthere is this instruction: Add this in between the /Context tag of the examples context and the /Host tag closing the localhost definition.
