Please provide the problems you are getting. I think you will get http://en.wikipedia.org/wiki/Cross-site_scripting issues since the url is accessing from out side of wsearch.nlm.nih.gov context. If you are sure that it is a rest webservice call then instead of a direct webservice call, Do a server call(Internal Call to Servlet/ASP/PHP by matching some URL pattern) and then invoke the web service url from there by using third party RestClient libraries . Eg. RestClient for JBoss & Java
