Hi all,
[excuse me for my poor English]
I develop a code that comes following:

1.       public class ConfigureDevice extends JApplet {        
2.          // Some Code
   
3.          SAServer sas = new SAServer();
            sas.start();
           
            SASProtocolOptions opt = new SASProtocolOptions();
            opt.setProtocol(SASClient.TCP_PROTOCOL);
            opt.setApplet(this);
           
            api = new SnmpAPI(false);
            ses = new SnmpSession(api);
            ses.setProtocolOptions(opt);        
            try{
                ses.open();
                }
            catch (SnmpException e)
            {
                label.setText(e.getMessage()); // Type of label is JLabel, which shows an exception.
   
4.              label.validate();
            }
5.       // Some Code
   
6. }
   

As you see, my class extends JApplet. So, I run code by JAppletViewer and seems that everything is OK, but when I run code by IE, I discovered that SnmpSession(here is "ses") unable to create a SASClient. If I want to negotiate carefully, I catch this Error:

1. Error in open: Unable to create SASClient
