      A DESCRIPTION OF THE PROBLEM :
      import java.lang.reflect.*;
      import org.w3c.dom.*;
      import org.w3c.dom.html.*;

      /** Simple applet which fails to get an HTMLTextAreaElement from DOM */

      public class DOMDump extends java.applet.Applet
      {
          private HTMLTextAreaElement htae;

          public void start()
          {
              try
              {
                  Class c = Class.forName("com.sun.java.browser.plugin2.DOM");
                  Method m = c.getMethod("getDocument",
                                         new Class[] { java.applet.Applet.class });
                  HTMLDocument doc = (HTMLDocument) m.invoke(null, new Object[] { this });
                  htae = (HTMLTextAreaElement)doc.getElementById("textareaid");
                  htae.setValue("This is a textarea");
              }
              catch (Exception e)
              {
                  e.printStackTrace();
                  System.out.println("Error with Java Plug-In");
              }
          }
      }


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Compile the applet source given below. Then embed it in the following html document:


      <html>
        <head>
          <title>
            DOM Dump test applet
          </title>
        </head>
        <body>
         <form method="post">
            <textarea name="textbox" id="textareaid" rows="25" cols="18"></textarea>
         </form>
          <applet code=DOMDump.class
            archive="DOMDump.jar"
            width=10 height=10
            mayscript>
          </applet>
        </body>
      </html>



      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The text "This is a textarea" should show up in the textarea of the html page as soon as the applet starts.


      ACTUAL -
      No text shows up.
