Obviously you CAN modify third party jars. There is nothing
technically stopping you. What you need is permission to do so.  That
is a political problem.  Perhaps that limitation can be bypassed if
you can't find another solution.

What you can do is open them the jars up and bundle them back into a
big jar that you sign.

I have heard it is possible to have different signers on different
jars if you use Java WebStart.

You might also explore the possibility of resigning an already signed
jar so that all jars have the same signer.

Another possibilty it so pre-install the needed jars in the client ext
dirs. You might write a little installer to do that. I think then it
does not matter how they are signed.

you are just creating more places you will have to search for them.
