Setting security for applets

To set up secure access for applets that will access the file system or Notes® Java™ classes through Notes®, you must first set up an access control list (ACL), then set up an execution control list (ECL) for each user or group. The ECL controls access to the file systems and to the Notes® classes on the workstation.

Complete these steps to set up secure access for applets that will access the file system or Notes® Java™ classes through a browser.

An applet intended for run-time access of lotus.notes.noi extends AppletBase and puts its functional code in the methods notesAppletInit() and notesAppletStart(), as shown in the sample code, and in notesAppletStop(). You do not have to distinguish between local and remote access. AppletBase will make local calls if the applet is running through the Notes® client and remote calls if it is running through a browser.

Here is an example of an applet that makes NOI calls:

import lotus.notes.noi.*;

public class platform4 extends AppletBase
{
 java.awt.TextArea ta;

 public void notesAppletInit()
  {
    setLayout(null);
    setSize(100,100);
    ta = new java.awt.TextArea();
    ta.setBounds(0,0,98,98);
    add(ta);
    ta.setEditable(false);
    setVisible(true);
  }

  public void notesAppletStart()
  {
    try
    {
      // Can also do getSession(user, pwd)
      Session s = this.getSession();
      if (s == null) { //we were not able to make the connection, warn user
        ta.append("Unable to create a session with the server");
        return;
      }
      String p = s.getPlatform();
      ta.append("Platform = " + p);
    }
    catch(Exception e)
    {
      e.printStackTrace();
    }
  }
}
