I think you are nearly there.

First you should do everything on the command
line and log this.

Place the same commands in a sh file (connect.sh for example) and
see if sh connect.sh works.

Then if that works, the script may either be called
by <exec executable=3D"bash">
        <arg value=3D"connect.sh"/>
    </exec>
or the script may be placed in-line in the build file and
use made of <shellscript/>, remembing to excape
any xml characters like '<' and '--'

the ssh client from openssl looks like
ssh [options] host [commands]

If commands  are not present, the ssh program
logons to host and sends the std input to a shell overthere.

in a sh (or bash) script one may place std input to a command
by using the "here document" syntax - see man bash (or google
man bash) for detailed explaination. This is

command << END
 input for the command...
END

The first shellscript you did looks correct except for
missing the "<< END" and not placing the terminating
END at the start of a line.
The following sh script should work.

         ssh -l michaeltaft jyotish.sourceforge.net << END
         cd /home/groups/j/jy/jyotish/htdocs/
         gunzip FJWeb.tar.gz
         tar xf FJWeb.tar
         rm FJWeb.tar
END

placing this inline in a build script means that you must excape
the '<' character as it is a xml token character. This can be
excaped by using &lt; or by placing the text in a CDATA block.
The following should work.

    <taskdef resource=3D"net/sf/antcontrib/antcontrib.properties"/>
    <shellscript shell=3D"bash"  output=3D"dir2.txt">
         ssh -l michaeltaft jyotish.sourceforge.net &lt;&lt; END
         cd /home/groups/j/jy/jyotish/htdocs/
         gunzip FJWeb.tar.gz
         tar xf FJWeb.tar
         rm FJWeb.tar
END
         </shellscript>

:::NB:::
at the moment shellscript does not send the in-line text
to the shell as std input. When ant 1.6 is released, shellscript
will be updated to do this.
