indexing from Java

[Erik Hatcher]

I'm refactoring a command-line application that indexes RDF data to  
index into Solr rather than directly into a Lucene index.

In looking at the code, it looks like it'd be difficult to do this  
without actually doing an HTTP POST.  Or is there a clean way to  
leverage Solr's infrastructure without POSTing into it?  I don't even  
need Solr running while indexing.  Is this possible easily?  If so  
what API should I be using?

Thanks,
        Erik
