[Geoserver-users] Find out path of geowebcache.xml

Hallo, I need to parse the content of geowebcache.xml from Geoserver.
I tried this tutorial:
http://docs.geoserver.org/2.5.x/en/developer/programming-guide/ows-services/implementing.html

and my first attempt was:

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletException;
import org.vfny.geoserver.global.GeoserverDataDirectory;

public class CustomCapabilities {

public CustomCapabilities() {}

public void getCustomCapabilities(HttpServletRequest request,
HttpServletResponse response)
throws ServletException {

           String geoserverDataDir =
GeoserverDataDirectory.getGeoserverDataDirectory().getAbsolutePath();
           File geoWebCacheXml = new File(geoserverDataDir +
"/gwc/geowebcache.xml");
  ....
       }
}

The problem is, this does not longer work if geowebcache.xml isn't in
GEOSERVER_DATA_DIR/gwc/geowebcache.xml
Is There a easy way to find out on runtime which geowebcache.xml is really
used by Geoserver?

I'm using currently Geoserver 2.3.0, which provides Geowebcache 1.4, but I
could upgrade if needed (the upgrade is already on the TODO list)

Thank you, Tommaso

Hallo, I found finally the solution:

import org.geowebcache.storage.DefaultStorageFinder;
import org.geowebcache.util.ApplicationContextProvider;
import javax.servlet.ServletContext;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

.......

HttpSession session = request.getSession();
ServletContext servletContext = session.getServletContext();
WebApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(servletContext);
ApplicationContextProvider applicationContextProvider = new ApplicationContextProvider();
applicationContextProvider.setApplicationContext(appContext);

DefaultStorageFinder gwcStorageFinder = new DefaultStorageFinder(applicationContextProvider);

String gwcDataDirPath = gwcStorageFinder.getDefaultPath();
File geoWebCacheXml = new File(gwcDataDirPath + "/geowebcache.xml");

Thanks anyway, Tommaso
