Question

After an upgrade to XP and Java 1.6 one of our intranet apps is experiencing a problem when running a java applet in the browser. The java applet is a document editor and accepts a parameter to where the document is located. I assume it copies this file to the users machine for editing. I wish I knew more but I don’t have the source…dam!

we are getting a java.io.IOException on a machine running XP-IE6-Java 1.6. This problem doesn’t happen on our older Win2K-IE6-Java 1.3 so we are certain its isolated to the desktop and not the server (99% sure anyway).

A little info: If you try to run the applet twice in a row, it works the second time. The first time it fails. Also, the error message box appears BEFORE the orange java loading logo appears embedded in the browser.

I have also entered in the following information into the policy file and reloaded the policy file via the console.

grant codeBase 'http://intranetserver/*' {     permission java.security.AllPermission;  }; 

here is a dump of the stack trace. Thanks for your time 🙂

Answer 1

I worked out the problem. Turn off temporary files in the java control panel.
