Answer 1

You need to put commons-fileupload.jar and commons-io.jar to your WEB-INF/lib forlder. Classpath is used during build, but they must be available during runtime also.

Actually, if you had used IDE for Java EE development (like Eclipse) putting these Jars to WEB-INF/lib would be enough, as they would be automatically visible in the claspath for build.
