Creating Signed Applets

Hello Friends,


I am trying to create a signed applet using jdk 1.1.8(it's old times
back for me...), so I am trying to use the "javakey" tool that comes
with this jdk. Now, for some reason when I am doing the step of
actually signing the jar file by doing:

"javakey -gs sign.directive MyApplet.jar"

I am getting following error:

error generating signature: java.util.zip.ZipException: invalid entry
compressed
size (expected 9525 but got 9270 bytes)[invalid entry compressed size
(expected
9525 but got 9270 bytes)]

Could you guys & gals please see if you could remember seeing and
resolving something like this from the days of jdk1.1. I would really
appreciate your help and time. Thanks in advance.

Regards,
Manjari.

Why on earth would you do that?
If you wanted to target the MS 1.1VM
(whcich I advise people to get rid of
for security concerns, you really need
to develop in the last Java that MS spoke,
1.1.4

I noticed that Java compiled to be
readable by 1.1 JVM's (the -target
option) was slightly bigger in bytes
than for the 1.4 VM.  That may be it..

I don't get it.  What do you mean
"installs it's own java plug-in" when
you have the code?  Comment out
the bit(s) that install 1.1.8 and you
can likely compile and run under
1.4 (and use jarsigner, ..while
you're at it!)

I went looking for further info
on the 'javakey' tool you mentioned
and found that most of Sun's links
either go nowhere, or lead you to a
page mentioning it has entered 'EOL' process,
http://java.sun.com/docs/books/tuto...gn/signing.html
has several such links..

Mabe it's time to update!

(and please do not top-post, it
destroys the thread of a
conversation)
