As far as I can tell, your message doesn't tell us what the problem is. 
So I'm having a hard time coming up with a useful response.


If the problem is that the response isn't JSON, then either you need to 
tell Solr that you want JSON, or run a new enough version that the 
default response format *IS* JSON.  I do not recall which version we 
changed the default from XML to JSON.


One thing you should be aware of ... if the javascript is running in the 
end user's browser, then the end user has direct access to your Solr 
install.  That is a bad idea.


Thanks,
Shawn
