java mysql database-connection jetty c3p0

Jetty 7 + MySQL Config [java.lang.IllegalArgumentException: Object is not of type class org.eclipse.jett y.webapp.WebAppContext]

I've been trying to get a c3p0 db connection pool configured for Jetty (7.4.1.v20110513), but I keep getting a java.lang.IllegalArgumentException :

Here are my web.xml and jetty-web.xml files in my WEB-INF directory.

Currently I have placed the following jars in my WEB-INF/lib directory:

c3p0-0.9.1.2.jar
commons-dbcp-1.4.jar
commons-pool-1.5.6.jar
mysql-connector-java-5.1.16-bin.jar

Someone please tell me what is wrong with my configuration.

Solution

Your jetty-web.xml is still referring to org.mortbay.* which is for Jetty 6.

For Jetty 7,change

org.mortbay.jetty.webapp.WebAppContext to org.eclipse.jetty.webapp.WebAppContext

and

org.mortbay.jetty.plus.naming.Resource to org.eclipse.jetty.plus.jndi.Resource.
