Java Security Dialog When Accessing MUOnline

Please note this issue only affects Windows users who are using Java version or higher.

When logging into MUOnline, users will be presented with a security dialog pop up which says “Java has discovered application components that could indicate a security concern.” In order to make full use of the tools in MUOnline (My Computer file upload, chat and whiteboard, and HTML creator) you must click “No” to this dialog box.

A second option is to allow mixed code to run with protections.  This option will not show the security dialog when logging in.
To allow mixed code do the following:

  1. From the Start menu click on Control Panel
  2. Click Java
  3. Click the Advanced Tab
  4. Under “Mixed Code” choose “Enable – hide warning and run with protections” (see screen capture below)
  5. Click OK
