I've checked the documentation and yes I was reading the 5.0 version not the
5.5 one! However I've followed the new instructions and still get the
following error:
javax.servlet.ServletException: Unable to get connection, DataSource
invalid: "org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC
driver of class '' for connect URL 'null'"
The server.xml file now reads as follows:
<Context path="/DBTest" docBase="DBTest"
debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="javauser" password="pilks2"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/fyptest?autoReconnect=true"/>
</Context>
Any ideas what's wrong now?

There is no ResourceParams in 5.5. Check the documentation again, and
make sure you're looking at the docs for 5.5 not 5.0.

advised in the Tomcat set up pages. So would it make any difference
removing one of these or as it's ignored does it not matter?
