I don't work for websolr, but I do quite a bit of work with Apache Solr. I'd imagine Java integration is supported through the native Java client, http://wiki.apache.org/solr/Solrj, which is maintained by the Solr team. There are also a number of Solr client libraries for Python, Ruby, PHP, etc. All searches against a Solr index take place over HTTP through an RPC interface, so building an API for a specific language relatively straightforward.

You list Java as supported on this page, but the link 404s. http://websolr.com/guides/solr/clients Do you guys support Java integration?

Thanks for the heads up on that 404, I'll take care of that. See cedrichurst's comment for what I ought to be linking to.
