I have a simple site, that uses just four HTML pages. One page has a <div id=main_container /> element. From the GWT application I use the RootPanel.get("main_container") to access that element. The GWT app uses GWT-RPC to connect to a server (written in java). My problem is how to test it on xampp, because if I compile the GWT app and upload the war files and put inside it the four HTML files, then I can access all of the pages except the one that contains the <div> element. I need some help here!
If you are using GWT-RPC, you also need an Application Server like jetty or tomcat. Apache alone is not enough.
If you are developing your app, there is no need for apache as you can run your whole web app in DevMode or just jetty.
In production what you want to do is set up Apache as a proxy to your web app running on jetty. Just to be clear, you cannot run a GWT app that also uses GWT-RPC on most shared host environments.
