OK, if you're compiling and running against the same versions, then that error means that you haven't set your paths correctly so Solr can find your custom jar. In solrconfig.xml you should add a <lib...> directive that points to your custom jar file.
I usually start by using an absolute path here until I get the jar loading properly. At that point you can (and should) move it to a relative path. I use the absolute path to start since setting the relative path can be tricky.
