failing to restart solr server - solr

Question

I just installed a Hebrew plugin in Solr and tried restarting the server to use it.
I used this (my core is called techproducts):
http://localhost:8983/solr/admin/cores?action=RELOAD&core=techproducts
What I got In response is this error, seams like I placed the files in the wrong place:
{
"responseHeader":{
"status":500,
"QTime":832},
"error":{

I think the problem is with the location of the plugin files. If you know where should I be placing the files, do tell me. Any help would be app-reciated! thanks!

Answer 1

Solr will show which directories it looks in for jar files when starting up, so if you watch the Solr log you'll see what the existing options are.
However, you can add your own directory (and pattern) to the list of existing directives. These go in solrconfig.xml for your core:
<lib dir="../../../contrib/extraction/lib" regex=".*\.jar" />
Replace the path given in dir=".." with the path to the directory containing your own jar files.

Answer 2

I forgot to add H-spell files to the route. Silly mistake.
the server restarts now, but it still doesn't seem like the plugin is integrated.
thanks for the help.
