security exception fired by javascript and ok inside the applet

hello,

I wrote a signed applet with a method to read files from the user's hard drive

the web page contains 2 buttons :

1) one included in the html part : form -> input type button -> javascript function -> java method

2) one includes in the java applet : JButton -> ActionListener -> class actionAdapter -> actionPerformed -> same java method (as in 1)

if I click on the html button, I've got a security exception

if I click on the java button, I can read local files from the hard disk

do you have an explanation ?

my configurations are :

- 1.5.0. java, windows 2000, IE 6 or (1.0.6 or 1.5 ) firefox

- 1.4.2 java, fedora c4, 1.0.7 firefox

Hi.At me a similar problem. If to use jre1.4.1 - that both buttons work.

You have to use doprivileged becuase trusted (signed applet) code is

called from untrusted (javascript) code. The whole stack needs to be trusted

in order for it to work.
