Slight issue with classloading and DataImportHandler

[Brendan Grainger]

Hi,

I set up the new DataimportHandler last night to replace some custom  
import code I'd written and so far I'm loving it thank you.

I had one issue you might want to know about it. I have some solr  
extensions I've written and packaged in a jar which I place in:

solr-home/lib

as per:

http://wiki.apache.org/solr/SolrPlugins#head-59e2685df65335e82f8936ed55d260842dc7a4dc

This works well for my handlers but a custom Transformer I wrote and  
packaged the same way was throwing a ClassNotFoundException. I tracked  
it down to the DocBuilder.loadClass method which was just doing a  
Class.forName. Anyway, I fixed it for the moment by probably do  
something stupid and creating a SolrResourceLoader (which I imagine  
could be an instance variable, but at 3am I just wanted to get it  
working). Anyway, this fixes the problem:

  @SuppressWarnings("unchecked")
  static Class loadClass(String name) throws ClassNotFoundException {
    SolrResourceLoader loader = new SolrResourceLoader( null );
    return loader.findClass(name);
     // return Class.forName(name);
  }
