I’m going to start this out by saying I’m not a Java programmer, I’m a PHP programmer.
I ran into a situation were websockets weren’t going to cut it and I found this site that offered a solution:
http://stephengware.com/proj/javasocketbridge/
It’s basically a Jar that you can load in and control with JavaScript. It works great, I’d highly recommend it to anyone needing similar functionality. However, since the Jar was not signed, every time the page loads, it shows a security warning. It’s a little annoying and I thought that if I self-signed the Jar, it would have the ‘Never show me this again’ / ‘Allow Forever’ check box enabled. This is to be deployed internally to our organization, so signing it with a paid cert doesn’t seem necessary.
The problem is that as soon as I sign the Jar, it doesn’t work. I get a class not found error. I’ve looked at dozens of sites that show you how to sign Jar files and googled this to page 10, and I can’t find anyone that’s had this kind of issue.
I’m going to include the parts that I think are needed, if you need something else let me know and I’ll get it.
Applet code:
<applet id="JavaSocketBridge" archive="JavaSocketBridge.jar" code="JavaSocketBridge.class" width="400" height="30"></applet>
How I signed the Jar (in an administrator command prompt):
C:\Program Files\Java\jdk1.7.0_07\bin>keytool -genkey -keyalg rsa -alias crtlive
Enter keystore password:
What is your first and last name?
[Unknown]: first last
What is the name of your organizational unit?
[Unknown]: Tech
What is the name of your organization?
[Unknown]: ourorg
What is the name of your City or Locality?
[Unknown]: city
What is the name of your State or Province?
[Unknown]: ST
What is the two-letter country code for this unit?
[Unknown]: US
Is CN=first last, OU=Tech, O=ourorg, L=city, ST=ST, C=US correct?
[no]: yes
Enter key password for <crtlive>
(RETURN if same as keystore password):
C:\Program Files\Java\jdk1.7.0_07\bin>keytool -export -alias crtlive -file crtlive
.crt
Enter keystore password:
Certificate stored in file <crtlive.crt>
C:\Program Files\Java\jdk1.7.0_07\bin>jarsigner JavaSocketBridge.jar crtlive
Enter Passphrase for keystore:
Warning:
The signer certificate will expire within six months.
C:\Program Files\Java\jdk1.7.0_07\bin>keytool -export -alias crtlive -rfc -file s
ig.x509
Enter keystore password:
Certificate stored in file <sig.x509>
C:\Program Files\Java\jdk1.7.0_07\bin>
I’ve opened up both the unsigned and signed Jars and the source files are identical, there are just two additional files in the META-INF folder on the signed Jar: CRTLIVE.RSA and CRTLIVE.SF.

I’ve googled for everything I could think of, any help would be appreciated.
Thanks!
When we moved from java 6 to java 7 for our java web start product, we found that java 7 would not let our previously self signed jar files run.
We found that java 7 would not accept a Root CA that we had created. Once we used a trusted Root CA the problem went away.
Now, it might be possible to find a way around this. I suggest looking into this (search for keytool): http://www.oracle.com/technetwork/java/javase/jdk7-relnotes-418459.html
Specifically:
Area: Tools
Synopsis: A new keytool command (-gencert) is provided to generate a non self-signed certificate. A new option (-ext) is provided to generate several X.509 v3 extensions for the -gencert, -genkeypair, and -certreq commands. There are also other new commands and options for the keytool and jarsigner tools. See the keytool and jarsigner tool docs for more information.
