Re: How can I get the SCADomain refererce in a polciy module?

Maybe this can give you some hint, I use a listener to get SCADomain
from Web Servlet Context:

package xxxx;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import org.apache.tuscany.sca.host.embedded.SCADomain;
import org.apache.tuscany.sca.host.webapp.WebAppServletHost;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;



public class ScaWebContextInitListener implements ServletContextListener {
        
        private static Logger logger =
LoggerFactory.getLogger(ScaWebContextInitListener.class);



    public void contextInitialized(ServletContextEvent event) {
        SCADomain scaDomain =
(SCADomain)event.getServletContext().getAttribute(WebAppServletHost.SCA_DOMAIN_ATTRIBUTE);
        if (scaDomain == null)
                logger.error("SCADomain has not found in context!");
        else
                logger.info("SCADomain has found.");

        //......
    }


}
