Signing Applets
Hi
For the past week i have been trying to sign an applet.
The reason for having my applet signed, is because i need to access a serial port. So the best solution i could come up with is signed applets.
I have been working off this site for the last week. I have managed to understand/and get to step 5 and then they sort of lose me, sigh
http://java.sun.com/developer/onlineTraining/Programming/JDCBook/signed.html#example
I have also visited
http://mindprod.com/jgloss/signedapplets.html
My applet also uses other JAR files because i need access to the protocols that my company uses in order to talk to the device on the serial port
So my questions are
1)How exactly does can my applet have permissions in order to access the serial port?In the example above they talk about the Write.jp file. I understand what is in the file, but how do i link it to my applet?
2)Are there other sites that i can go read that will explain things to me like a 5 year old? And yes i have googled "Signed applets" and i have read up on signed applets
MY APPLET CODE:
<HTML>
<Head>
<Title>ASimpleProgram</Title>
<Body>
<Applet archive="ajaxreports.jar,comm.jar,rtlib.jar" Code="ReadTagApplet.class" width="500" height="50" name="RA">
</Applet>
</Body>
</HTML>
And my Java Applet Code

System.err.println("********************************");
}
returntrue;
}
}
}
catch (Exception cme){
System.err.println((new Date()).toString()+" "+Thread.currentThread().getName()+
": Unable to read from ixp1.properties File");
}
returnfalse;
}
}
Do i have to sign the JAR files that have my other classes too?
Any and all suggestions would be great.
:)
