XMLHttpRequest cannot load http

Question

I am a beginner at the web applications realm and I'm trying to build a simple web site that sends an httprequest (with javascript XMLHttpRequest object). the web page (html) sits on an "HTTP Preview at localhost" server and the servlet sits on another server "Tomcat v7.0 Server at localhost"

When I try to send the http request I get the next error:

XMLHttpRequest cannot load http://localhost:9999/ebookshop/querymp?author=Tan+Ah+Teck&price=50. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin > 'http://localhost:8080' is therefore not allowed access.

My guess is that it happens because I'm trying to access another server but I don't know how to solve it. On eclipse's browser I see the result and that works fine.

is it a service that you are calling??? Put this -->> Access-Control-Allow-Origin: * , in your header and it will work! — MixedVeg, Dec 06 '14 at 11:43

You need to enable CORS on the server in your case localhost is the one. you need to have this on request header

Access-Control-Allow-Origin: http://localhost:9999

So adding "Access-Control-Allow-Origin" helped.. But it doesn't seems right having 2 different servers e.g: 1.HTTP Preview at localhost 2.Tomcat v7.0 Server at localhost

Is there a way combining the "Http Preview server" with the Tomcat server? or it is unnecessary?
