Why are Java applets in the DFWorks Production Workflow view blocked by security settings.

Product Feature: General

Operating System: Windows 7

Starting with Java 7 Update 51, trying to run Java applications generates messages

Java applications are blocked by your security settings.
Missing Application-Name manifest attribute
Missing required Permissions manifest attribute in main jar

Java has further enhanced security to make the user system less vulnerable to external exploits. Starting with Java 7 Update 51, Java does not allow users to run applications that are not signed (unsigned), self-signed (not signed by trusted authority) or that are missing permission attributes.



The application that you are running is blocked because the application does not comply with security guidelines implemented in Java 7 Update 51.


As a workaround, you can use the Exception Site list feature to run the applications blocked by security settings. Adding the URL of the blocked application to the Exception Site list allows it to run with some warnings.

Steps to Add URLs to the Exception Site list

  • Go to the Java Control Panel (On Windows Click Start and then Configure Java)
  • Click on the Security tab
  • Click on the Edit Site List button
  • Click Add in the Exception Site List window

    Add url to Exception Site list
  • Click in the empty field under the Location field to enter the URL of the DFWorks webpage

    (URL should begin with http:// or https://)
  • Click OK to save the URL that you entered
  • Click Continue on the Security Warning dialog
