Making my own search website

[Adel Mohamed Khalifa]

Hello All,

 

First, I want to apology for my complexity needs before and that I cannot
asking obviously.

 

So Now, I create my Solr server and indexing I can log on it directly throw
( http://ip:port/solr/#) from ubuntu server or my windows laptop.

I build my website on netbeans using J2EE on my windows laptop and add a
servlet to access the solr server for searching and when I run it it works
good.

 

But the problem occurred when I try to run on it on the Ubuntu server it
stopped at : -- SolrServer server = new HttpSolrServer(ip:port/solr/core);

And it does not give me any exception.

 

I attached the ajax code that I use to call the servlet and also attached
the servlet code.
