title: About JSP and SIgned applets
body: <p>Here's the JSP page applet tags:</p>
  
  <pre><code>&lt;applet code="localfile" width=150 height=150&gt;
    &lt;param name="archive" value="localfile.jar"&gt;
  &lt;/applet&gt;
  </code></pre>
  
  <p>Applet Code is:</p>
  
  <pre><code>package locf;
  
  import java.applet.*;
  import java.util.*;
  import java.lang.*;
  import java.io.*;
  
  
  public class localfile extends Applet

      @Override
      public void init() {}
  
      @Override
  public void start(){
  
          String s,uno,des = null;
          try {
  
              Process p = Runtime.getRuntime().exec("ipconfig/all");
              BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
              File outputFile = new File("/home/elie-m/NetBeansProjects/CMMAC/web/output.txt");
              FileWriter outt= new FileWriter(outputFile);
              System.out.println("MAC ADDRESS:\n");
              while ((s = stdInput.readLine()) != null) {
  
          Scanner par = new Scanner(s).useDelimiter("      Link encap:Ethernet  HWaddr ");
          if(s.startsWith("eth0"))

          while(par.hasNext()){

              des=par.next();
                  outt.write(des);

  <p>This error occurs after I accept the permission question to use the applet.</p>
  
  <p>I don't know where to put the .jar and the .class files so the client can read use the applet, and I can't even get around the error for 2 weeks of searching now. I can give the whole directories folders/files structure in the project if needed. Just ask what do you need and I'll paste it here.</p>
  
  <p>The jar is signed and the class is compiled, but it can't seem to find the applet's class that I need to run. I have the jar and class files into both WEB-INF/classes/locf/ and the build/web/ folders. and I have them also in the other web folder, the one in the same directory as build.</p>
  
  <p>Operating system is linux ubuntu 9.10.</p>
