Java application blocking security Java 8 Update 45 -

my applet application blocked java security.

• i tried adding site trusted sites , didn't worked
• the medium security removed java 8 update 45

i know how remove security? wondering makes application unsafe , how make safe?

be have manifest entries such sample (adjust unique circumstances):

permissions: all-permissions codebase: https://app.mycompany.com/applicationfolder application-name: helloworld 

you may apply manifest through along lines of:

"%jdk_home%\bin\jar.exe" ufm ..\dist\application.jar manifest.txt
