Run exe using Signed Applet

[raktim banerjee]

Hello Sir!

I had been trying to run executable file encryption.exe in client side that is placed in the client's computer, using signed applet. I checked this:http://java.sun.com/developer/onlineTraining/Programming/JDCBook/signed.html

I have done step 1 to 6. But I am not able to understand :

7: Create the Policy File

There is no exact procedure described to use policytool. The signed applet is running in applet viewer. I want to run the applet in browser without involving the end user in the following steps manually:

6. Import the Certificate as a Trusted Certificate
7. Create the policy file
8. Run the applet 

Is there any way to check the signature without involving the end user?

It is not necessary to change the policy file if the applet is signed - both accomplish the same thing.

so if the applet is signed will it work on the client side simply without doing anything in the client side extra? Is it necessary to send the certificate to the client? or the end user will get the certificate automatically?

Yes

or the end user will get the certificate automatically?

Yes

The only thing you may have to do is to run the code as privileged code. See HowCanAnAppletReadFilesOnTheLocalFileSystem for how to do that.
