I have a Network Rail IT does web site Atrium Property - LIVE Web Link https://ap.networkrail.co.uk when you open the top link “Atrium Property Live” there is a problem with machines not running Java 6 update 18  .. I know but network rail won’t change it.

The problem revolves around the JAR file manifest does not contain the Permissions attribute.  

The Permissions attribute is used to verify that the permissions level requested by the RIA when it runs matches the permissions level that was set when the JAR file was created. This attribute is used to help prevent someone from re-deploying an application that is signed with your certificate and running it at a different privilege level. You set the attribute to one of the following values:

## permissions: sandbox - Indicates that the RIA runs in the security sandbox and does not require additional permissions.

## permissions: all-permissions - Indicates that the RIA requires access to the user's system resources.

After even java 7 update 45 java put in checks to make sure that was set.

Can I someone emulate 6 update 18 or maybe even java 7 update 45 on a Surface RT 8.1, fully updated in the UK as of 09/04/2014

I know that it does not support JAVA .. that's why I said run / emulate? I know it can be jail broken . but I don't want to do that.

you've actually found a version of java that supports the ARM processor AND Wini RT? The official position is that it is not supported. You could edit the signed code and then sign it yourself

David Johnson, CD - you can brake the RT and tweek an install, but I said that was  not wanted as it would open up risks.

you can still not accept unsigned .jar files all you have to do is setup a CA and create a code signing cert.
