Hi there

I have an app, which works fine standalone and in processing IDE, but I am trying to export and run it from the index.html.
The app (simplified code included), launches, requests that I trust it (because I signed it) and shows the image as
expected. However when I look in the Java console (as part of my browser) I see the following error messages:

trying dataPath
java.security.AccessControlException: access denied (java.io.FilePermission /null/data/HoCMP.xml read)
trying data/
java.security.AccessControlException: access denied (java.io.FilePermission /data/HoCMP.xml read)
trying absolute Path
java.security.AccessControlException: access denied (java.io.FilePermission /home/AntMan/Processing/Test/Simpler/Simpler/data/HoCMP.xml read)
Hello

Investigating I have found the lines this relates to (see below), which is basically the constructor of the object
which receives the location to the xml file which will be loaded ready to be parsed later on in the app:

   try
   {
     DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
     DocumentBuilder db = dbf.newDocumentBuilder();
     myDom = db.parse(fileName);
   }
   catch (java.security.AccessControlException e)
   {
     System.out.println("Found an error!!!!!");
     System.err.println(e.toString());
   }

From what I can find on the internet this would only happen if the app is not signed, which it is?

I am running Fedora 9, viewing the index.html with Opera and the Java console included with Opera.

This is my code:

//Simple.class

PFont font8;
MyParser tp;
boolean failed = false;

void setup()
{
 fill(0);
 smooth();
 size(800,600);
}

void draw()
{
 rect(0,0,800,600);
 
 try
 {
   System.out.println("trying dataPath");
   tp = new MyParser(dataPath("")+"/HoCMP.xml");
 }
 catch (java.security.AccessControlException e)
 {
   System.out.println("dataPath() failed!");
   System.err.println(e.toString());
   failed = true;
 }
 try
 {
   System.out.println("trying data/");
   tp = new MyParser("data/HoCMP.xml");
 }
 catch (java.security.AccessControlException e)
 {
   System.out.println("data/ failed!");
   System.err.println(e.toString());
   failed = true;
 }
 try
 {
   System.out.println("trying absolute Path");
   tp = new MyParser("/home/AntMan/Processing/Test/Simpler/Simpler/data/HoCMP.xml");
 }
 catch (java.security.AccessControlException e)
 {
   System.out.println("Absolute path failed!");
   System.err.println(e.toString());
   failed = true;
 }

 finally
 {
   if (failed)
       System.out.println("Failure occured");
   else System.out.println("No failures!");
 }

 strokeWeight(0.25f);
 font8 = createFont("Serif",28);
 textFont(font8);
 fill(255);
 if (failed)
 {
  text("Some or all failed",370,300);
  System.out.println("Some or all failed");
 }
 else
 {
   text("Hello",370,300);
 System.out.println("Hello");
 }
 noLoop();

}

You posted twice the thread (a glitch quite common with this new forum), you should update where you already have an answer...
