Should i add the attributes in manifest.mf file of other jars also ?
My observations are:
After adding Trusted-Library : true and Permissions: all-permissions in all jars(doesn't matter whether they are signed or unsigned) it works fine. All the jars are loaded.
But why do i need to add these particular attributes in all the jars(Some of jars are third party jars)? According to definition of Mixedcode and usage of the attribute Trusted-Library: true it should allow other jars once it is updated in Manifest.mf file of jar containing the applet.
