RE: Printing from browser

1998-10-14 Thread Tar . Zoltan


Sorry for my English.

I had this problem a month ago. I got this solution to it:

I suggest to read the Signing and Verifying
JAR Files tutorial, this is a part of the Java Tutorial on
java.sun.com

In short:
I use the Java plugin, and signed jar file.
Create a certificate, with the javakey utility. Then make
a jar file from your class fajl. With javakey, you can sign
the jar file.
On client you must have this certificate too. It is suffice:
copy your javakey database file to the client, and make
changes in the client java.security file. (lib/security)

https

1998-12-02 Thread Tar . Zoltan


Hello

I'm working on a project which needs to send information
such as credit card number to a web server, I'm thinking
of using protocol https, does java support https?

If it does, how?

Zoltan TAR



RE: https

1998-12-03 Thread Tar . Zoltan


It 's ok.

But I use the Sun's plugin, not the Netscape built-in Java
plugin.

Are you sure that, it is true for the Sun's plugin?
I didn't find any class that contains SSL, or HTTPS in their
name.

I use JDK 1.2 (or Java 2?) debugger, it has got a lot of
functionality
that in Jbuilder hasn't.
