No, maven can manage the entire project life cycle including compilation
and packaging into a jar file.

do you mean that compiling WordCountTopology class using Eclipse or

Re: Error in submitting Topology
Posted by Nathan Leung <nc...@gmail.com>.
It looks like for some reason the java file got included as a text file,
not compiled as a class file. My recommendation is, since you do not seem
to be able to diagnose that yourself, you should familiarize yourself with
the toolchain, including jdk tools and maven. Then you will be able to
debug this problem yourself. :)
