Hi,
I would like to be able to do conditional URI forwarding. Something like <?forward uri="some_uri" if="system_properties_is_set"?> in a zul file.
I intend to set System properties using JVM args.
How would I go about doing this?
Thanks in advance.
Hi yapith,
You can set the attribute of (JSP)application object, then get it by EL.
My suggestion is use ServletContextListener, like this:
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
public class InitServer implements ServletContextListener {
public void contextInitialized(ServletContextEvent sce) {
//replace: read system property
sce.getServletContext().setAttribute("foo", "foo");
}
public void contextDestroyed(ServletContextEvent sce) {}
}in ZUL:
<?forward uri="browser.zul" if='${foo eq "foo"}' ?>Remember set "listener" element in web.xml
Regards,
Monty Pan
