Im trying to write an applet with JFileChooser, so the user can browse the harddrive and click on a file as input

I have an applet written that allows the user to type the input, the input is then used to parse a file.  I need to have the user to be able to browse for a file on the hard drive, and this then to be used again as input to be parsed. When I try this I get various security issues. Would it be possible for  someone to give me some advice on how to go about this.

Thankyou.


import java.awt.*;

//-------------------------------------------------------------------
//  Main applet class

public class FileApplet extends java.applet.Applet {

  public void init() {
   
     add(new Button("Load File"));
 
  }//init

  public boolean action(Event x,Object arg) {
   
     if (x.target instanceof Button && ((String)arg).equals("Load File")) {
            ParsePDB pPDB = new ParsePDB();
            pPDB.other();
     }//if
     return true;
  }//action

  //  These methods allow the applet to also run as an application.

  public static void main(String args[]) {
   
            ParseFile pFILE = new ParseFile();
            pFILE.another();
     
  }//main
 
}//FileApplet
