JAR resources in JNLP file are not signed by same certificate

I am running my application under Java Web Start with different jars signed. I following the advances use multiple JAR files in JNLP files below.
But i message error "+*JAR resources in JNLP file are not signed by same certificate*+" is posted still.
Could you please help me to solve it?

Answer 1

Are all of the jars in extlib.jnlp signed by the same cert? I think that the extension mechanism lets you get around having all of the jars for an overall app have the same signer, but I think it's still required that all of the jars within a given jnlp file have to have the same signer. So for you, all the jars in index.jnlp have to be signed by "cert A" and all the jars in extlib.jnlp have to be signed by "cert B". If that's not the case, you may need to split it up into multiple extensions.
