Specify different web.xml filename

[levier]

Hi,

Basically my question here is: how do I tell the gwt dev mode web
container (jetty at the moment) to look for another web.xml filename
when dev mode starts.


Background:
When running a GWT module in a dev mode, you can specify a -war
argument to pass different war directories.
This makes it possible to have 1 project and have totally different
modules in there. That's nice, but it becomes a hassle to maintain if
you have shared resources between those modules.

I have 1 project with 1 module 'DISC', but I want it to start it in
different modes at the same time.
So I have 2 gwt.xml modules, and use a rename-to 'DISCDEBUG' to let
GWT differentiate.

The problem with rename-to is that I also need to adapt the web.xml
and specify the new name in it on the url-pattern of the servlet-
mappings (DISC/ becomes DISCDEBUG/)

So I would like to have 1 web.xml for the production module, and
another webdebug.xml for the debug mode.
though ideally: just 1 web.xml containing a property {gwt.modulename}
or something which is replaced at startup of the webcontainer. But
support for using runtime properties in the web.xml depends on the
container implementation.


workaround:
* create separate war directories:
not usable: I would need to copy my whole 'war' directory to another
'wardebug' directory and maintain both these directories on changes.

Why aren't you simply renaming your debug module to the same name as the "production" one?

maybe you can use a "-server com.google.gwt.dev.shell.jetty.OurJettyLauncher" argument to launch gwt.
below is the source of OurJettyLauncher:

package com.google.gwt.dev.shell.jetty;

import com.google.gwt.core.ext.TreeLogger;

import org.mortbay.jetty.webapp.WebAppContext;

import java.io.File;

public class OurJettyLauncher extends JettyLauncher {

	protected WebAppContext createWebAppContext(TreeLogger logger, File appRootDir) {
		WebAppContext webAppContext = super.createWebAppContext(logger, appRootDir);

		String webXmlPath = System.getProperty("webXml");
		if (webXmlPath != null && !"".equals(webXmlPath)) {
			webAppContext.setDescriptor(webXmlPath);
		} else {
			webAppContext.setDescriptor("WEB-INF/boot.web.xml");
		}
		return webAppContext;
	}

}
