<p class="MsoNormal">I’m writing an application that accesses wms services on a variety of servers requiring the use of a proxy file. The application is running within Tomcat (v 6.0.18) and uses the jsp code at the bottom as the proxy. Everything works fine
for getcapabilities and getmap requests but when attempting a getfeatureinfo request I receive a java “no protocol” error. Can anyone provide a suggestion on correcting this? Thanks.</p>
