Attempting to inline Java into Perl via the Inline::Java module

Question

This is my first attempt to inline Java code in Perl. We cannot use the standard SFTP command on our system. This is out of my power. We have a jarfile called SFTP.jar which can

Answer 1

Okay. I figured it out. I had several things wrong:

• Under Study, I had both the Methods and Class, but I only should have the Class.

Wrong

use Inline (
    Java => 'DATA',
    J2SDK => $ENV{JAVA_HOME},
    CLASSPATH => $PERL_CLASSPATH,
    STUDY => ["SFTP", "close", "list", "get", "put", "remove"],
#    DEBUG => 4,
);

Right

use Inline (
    Java => 'DATA',
    J2SDK => $ENV{JAVA_HOME},
    CLASSPATH => $PERL_CLASSPATH,
    STUDY => ["SFTP"],
#    DEBUG => 4,
);

• When I declare the SFTP object as new, I have to give it the full Perl namespace:

Wrong

eval {$self->{CONNECTION} = new SFTP($server, $user, $password);};

Right

eval {$self->{CONNECTION} = new FMS3::Sftp::SFTP($server, $user, $password);};

You spend several hours on something like this, give up, and then suddenly the light in the ol' dusty attic comes on. I'm a fairly smart guy. Stick a screwdriver in a live socket, and after the third or fourth time, I go "Hey, maybe that's not a good idea".

Answer 2

Try Net::SFTP::Foreign, if you use it with plink (the command line ssh client from the PuTTY package) you would not need any other module to get it working.
