[ale] Crazy Perl + Java question

[Christopher Fowler]

Here is what I came up with.

I created an interface that used Getopt to allow the user to pass all
arguments needed to create a JD object.  I then added a -e (exec)
options that allowed the user to pass the method and arguments for that
class that needed to be executed.

In this example I called up my remote JCD server and asked it for the
console buffer contents of my Soalris 9 machine.

./jcd.pl -u ensign -p password -s 192.168.2.231 -S -e
"get_buffer('Solaris')"

What I got back was:


sol9 console login: root
Password: 
May 21 14:28:38 sol9 login: ROOT LOGIN /dev/console
Last login: Thu May 20 23:53:11 on console
Sun Microsystems Inc.   SunOS 5.9       Generic May 2002
# passwd
passwd: Changing password for root
New Password: 
Re-enter new Password: 
passwd(SYSTEM): They don't match.

Please try again
New Password: 
Re-enter new Password: 
passwd: password successfully changed for root
# ^D
sol9 console login: 
sol9 console login: 
sol9 console login: 


The beauty of this is that the '-S' switched used SSL as the connection
and I did not have to waste my times with the problems of java not
allowing a connection to a remote site that did not have a signed cert.

Unless there is a way to call perl code directly from Java I think this
would be the best way.  I guess I could write a JNI interface that can
return Java objects but that might be a royal PITA.
