Hi All,
Well I've finally go my signed applet to work on Windows Internet Explorer using CAB file and I'm trying to get it to work on MAC Internet Explorer:
I followed the instructions at the following site to create a self-signed applet for testing:
However I am getting a Apple security exception when trying to write to a file output:
/29/2002 @ 8:27:46
throwable exception
file writing test
trying to write to file: output.txt
Exception occurred during event dispatching:
com.apple.mrj.JManager.JMAppletSecurityExc: security.checkwrite: output.txt, /Macintosh HD/Applications (Mac OS 9)/Internet Explorer 5 Folder/output.txt
at com.apple.mrj.JManager.JMAppletSecurityOld.checkWrite(JMAppletSecurityOld.java)
at java.io.FileOutputStream.<init>(FileOutputStream.java)
at java.io.FileWriter.<init>(FileWriter.java)
at testapp.actionPerformed(testapp.java:121)
at java.awt.Button.processActionEvent(Button.java)
at java.awt.Button.processEvent(Button.java)
at java.awt.Component.dispatchEventImpl(Component.java)
at java.awt.Component.dispatchEvent(Component.java)
at java.awt.EventDispatchThread.run(EventDispatchThread.java

Here is the code I am using:
public void actionPerformed(ActionEvent e) {

if (e.getSource()==saveM) {
try {

if (Class.forName("com.ms.security.PolicyEngine")!=null) {
System.out.println("FOUND com.ms.security.PolicyEngine");
System.out.println("got file io permission");
} else {
System.out.println("DID NOT FIND com.ms.security.PolicyEngine");
} catch (Throwable t) {
System.out.println("throwable exception");
System.out.println("file writing test");
try {
System.out.println("trying to write to file: output.txt");
FileWriter f = new FileWriter("output.txt");
System.out.println("SUCEEDED in writing to file");
} catch (IOException a) {
System.out.println("IOEXCEPTION while trying to write to file");
} else {
try {
if (Class.forName("com.ms.security.PolicyEngine")
!= null) {
System.out.println("got printing permission");
System.out.println("got file io permission");

} else {
} catch (Throwable t) {


If you have any insight as to what I'm doing wrong, your help would be greatly appreciated.
I am running on a MAC OS 9, IE 5.0, and I installed MRJ 2.2.5.
With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
