:TODO: write short summary of why people might want to load custom code, and the loose definition of a "Solr Plugin"
How to Load Plugins
Plugin code can be loaded into Solr by putting Jars containing your classes in a lib directory in your Solr Home directory prior to starting your servlet container.
This is a relatively new feature (as of 2006-11-13) which uses a custom Class Loader. It's not yet clear exactly how successful this approach works on the multitudes of servlet containers available in the wild.
The Old Way
Another method that works consistently on any servlet container is to:
- unpack the solr.war
add a jar containing your custom classes to the WEB-INF/lib directory
- repack your new, customized, solr.war and use it.
