Dynamically determining the port number of a deployed application

Question

          Hi
          How do I dynamically determine the port number of a deployed web application ?
          I know HttpRequest.RequestURL() returns us the entire URL but I wanted to just
          know the port number .
          Is there any API do that ??
          Thanks

          kar,
          Here's what I do under WL 7 SP2:
          import javax.management.AttributeNotFoundException;
          import javax.management.DynamicMBean;
          import javax.management.MBeanException;
          import javax.management.ReflectionException;
          import javax.naming.Context;
          import javax.naming.NamingException;
          import weblogic.jndi.Environment;
          import weblogic.management.MBeanHome;
          String domainName,
          serverName,
          serverPort,
          serverUrl;
          // Getting the initial context
          Environment env = new Environment();
          try
          Context ctx = env.getInitialContext();
          if (ctx == null)
          // unable to retrieve a JNDI context
          return;
          // Retrieving the server-specific MBeanHome interface
          MBeanHome home =
          (MBeanHome) ctx.lookup(MBeanHome.LOCAL_JNDI_NAME);
          if (home == null)
          // unable to retrieve the local server MBean
          return;
          // Get the domain & server name
          domainName = home.getDomainName();
          serverName = home.getMBeanServer().getServerName();
          // The server port and address are a little trickier to extract...
          Object mbeanArray[] =
          home.getMBeansByType("ServerConfig").toArray();
          DynamicMBean mbean = (DynamicMBean) mbeanArray[0];
          try
          serverPort =
          Integer.parseInt(
          mbean.getAttribute("ListenPort").toString());
          serverUrl =
          mbean.getAttribute("ListenAddress").toString();
          catch (AttributeNotFoundException thrown)
          // caught a AttributeNotFoundException
          catch (MBeanException thrown)
          // caught a MBeanException
          catch (NullPointerException thrown)
          // caught a NullPointerException
          catch (ReflectionException thrown)
          // caught a ReflectionException
          catch (NamingException thrown)
          log.debug("caught a NamingException", thrown);
