Data import handler in techproducts example

[Jonas Vasiliauskas]

Hey,

I'm quite new to solr and java environments. I have a goal for myself to 
import some data from mysql database in techproducts (core) example.

I have setup data import handler (DIH) for techproducts based on 
instructions here https://wiki.apache.org/solr/DIHQuickStart , but looks 
like solr doesn't load DIH libraries, could someone please explain in 
quick words on how to check if DIH is loaded and if not - how can I load 
it ?

Stacktrace is here: http://pastebin.ca/3654347

Thanks,
