Webstart to Servlet Performance Issues

Question

Hi. I have a application that connects to a servlet to do database operations on a server. When it runs as either an application or an applet, the performance is great. However, when I try to deploy it with WebStart, the performance is terrible, a database lookup taking 40 secs to 1 minute, when a lookup would previously take 5-10 seconds. Has anyone else seen this? The hang up is in the DBConnect function listed bleow:
     public boolean DBConnect (String DBHost) {               
          String DBConnStr = DBHost;
          boolean ret = true;
          try {
               url = new URL(DBConnStr);
          } catch (Exception ex) {
               ret = false;
               System.out.println("Failed to create URL " + url.toString());
          try {
               con = (java.net.HttpURLConnection) url.openConnection();
               con.setDoOutput(true);
               con.setUseCaches(false); // to ensure that we do contact
                                                                 // the servlet and don't get
                                                                 // anything from the browser's
                                                                 // cache
               con.setDoInput(true); // only if reading response
               con.connect();
          } catch (Exception ex) {
               ret = false;
               System.out.println("Failed to connect to db servlet...");
          return ret;
Thanks,

Hi
I want to access a servlet from a WS Application and have performance problem Where did you set SecurityManager to null? In the servlet, or in your WS-Application?
If I set the SecurityManager to null in the Application which should access the servlet, I can't start the Application (and it is o.k). After that I tryed in the servlet as follow:
System.setSecurityManager(null);But, after that it wasn't better. Could you show me, how did you set SecurityManager to null (and where).
Thanks a lot.
P.S. In the WebStart I tryed two options: Proxi: withoutand Proxi:Webbrowser directBut it didin't help to.
