Using a Configuration file server-side in GWT

Question

I made a GWT App that use TCP/IP connections server side.

Now, I have harcoded the URL of the server that is used to connect:

private static final String URL = "https://localhost/ws";

I want to load this parameter from a config File like TOMCAT/conf/webService.conf or TOMCAT/conf/webService.xml but I can't find any propper way of doing this.

This app run in several servers and each server use a different WebService. I don't want to build a different app each time.

Answer 1

You may want to put such configuration in an XML or properties file on the server side. Then you can get this path at runtime from within a servlet

String path = getServletContext().getRealPath("/WEB-INF/classes/config");
File file = new File(path);
// Read as XML or properties file 

Answer 2

I realized that using Google app Engine won't let me load config files on the server. I'm not using GAE so I just disabled it and now I can use Config files.

Thanks!
