Well, MultiMapSolrParams is a subclass of SolrParams, so you actually
do use it in your code <G>....
But this looks like a classpath problem. You say your code compiles,
but do you make all the jars you path to during compilation available
to your servlet? And/or do you have any old jar files in your classpath?
