Java 1.7 Update 45 - Unable to run unsigned jar

I am able to run applets that have signed jar files on Internet Explorer with Java 1.7 Update 45.
I am however not able to run applets with unsigned jar files.
I tried clearing the cache.
I have also changed the security java control panel settings to Medium.
I still get the error JarSigningException.

Is there any way I can proceed here?
Are only signed jar files allowed? This looks like a major limitation.
Is there anyway I can tweak some settings to get unsigned applets to load?

Any help is appreciated.

  • Is there any way I can proceed here?

    Sure. Digitally sign the code with a certificate that links back to a trusted key chain.

    Are only signed jar files allowed?

    It is progressing towards that, yes.

    On your own machine? Probably for a little while longer, as Oracle continues to tighten the security along the lines you have discovered.

    For the users? No, nothing that is practical beyond 'educate your users as to the advantages of the digitally signed code', and to 'click OK when prompted'.
