It turns out that you have not done anything in Java and started to try the new version of jdk and it turns out when you wanted to run an applet, I realized I could not run on the local environment and even worse in web then I see some suggested reading sign the applet so I could run, sign the jar but the results were not running the same applet.
Then I realized it was nothing to certificate, as indicating the execution log was that I did not have the necessary permissions, I realized it was the famous «manifest.mf» was not configured properly, and that security policies and changed is only the upper and middle (was implemented according to the documentation I see from the version 7u51)
To not write more had to set the manifest.mf
Manifest-Version: 1.0
X-COMMENT: Main-Class will be added automatically by build
1. Codebase: *
2, Permissions: sandbox
3. Application-Name: MiApplet
4. Entry-Point: MiApplet.ejemplo
1. We indicate the domains you want to run if you’re going to run it locally we write 127.0.0.1 in my case I put «*» indicates that you can run in all domains.
2. We indicate jre to be executed in the sandbox and do not require other permissions is something like a sandbox.
3. The application name or title of the application.
4. Here we present our main class (the package is: MiApplet and my main class instance).
Remembering that this is a simple example if you are using another library must include it too. if you have a certificate we Trusted-Only: true only if we remember that we have purchased a certificate with some identity, as in my case do not buy anything, the economy 🙂
With that we have our list applet to run only one step left:
In html we add this to our applet to run.
<APPLET> code="MiApplet/ejemplo.class" archive="PruebaUno.jar" param name="permissions" value="sandbox" width=350 height=200 </APPLET>
If we add to this list as we run our applet.
now time to add to the list of exceptions to the folder that you can run your applet in a browser.
If you use windows 7 or 8:
Key in java (sometimes said set java or java set).
Now we‘ll open the security tab.
and go bottom where it says «Edit Site List«, we click and give add.
what we must do if we have a server either add http://www.choccac.com demos himself «http://www.choccac.com» but never like «http://www.choccac.com /miejemplo.html «because it does not work, if you want to add a folder must indicate the name eg http://www.choccac.com/miApplet, see I do not include any hTML. If you have wamp server or xamp only add «http: // localhost or ip of the machine». Remember that if you want to access from the local network must add the IP of the host machine that can run the applet. eg
server ip 192.168.43.5 -> copy the ip and add it to the list.
If you want to run it without any server, wamp, xamp, then you must add the address of the folder: eg file: /// c: / MiApplet /, noticing it was not put back the html because if you put it is not execute and file to be recalled that the three /// because it works.
This applet should now run without any certificate and remember.
applet example and set the jar manifest in netbeans and ready in html.

link(update 2) : MiEjemploV2
nyway this was the solution that worked I tried it on windows 7, windows 8 and windows xp (rip) and it works.
Now only plays open our applet firefox, internet explorer and chome or work.
