How do I get my java applets to work again

Question

So the java applets on my website stop working. I try updating browsers on all my computers (mac and windows), still the problem persists. Then as I did more research, I learn that I have to change my manifest . Does anyone have an example of what the new manifest should look like? Is there anything else I need to do? Please, please, provide an example. I have been reading about the new requirements , but I am still not clear on how to implement the changes.

Answer 1

So, your Applets must contain two things:

1. Code signatures from a trusted authority. All code for Applets must be signed, regardless of its Permissions attributes.

2. Manifest Attributes

   a. Permissions – Introduced in 7u25 , and required as of 7u51 . Indicates if the Applets should run within the sandbox or require full-permissions.

   b. Codebase – Introduced in 7u25 and optional/encouraged as of 7u51 . Points to the known location of the hosted code.

Sample of META-INF/MANIFEST.MF file:

Manifest-Version: 1.0
Created-By: 1.7.0_51
Permissions: sandbox
Codebase: www.java.com java.com
