i would set up pd to listen on the port _before_ sending data to it
(swap #2 and #3)


whether this is a good setup depends on "the data" you want to send.
(you are rather vague about that).

if the data is more complex (images,...) i would suggest to NOT use OSC
to directly send the data (even though OSC itself can afaik handle
blobs, pd/OSCx is not so good at it).

personally i would just setup a "server" process (be it written in java,
python, C or whatever) which continously reads in the data (either via a
cron-job, or an internal or external loop), store it on the harddisk and
then tell pd where it should look for the data.
mostly i use pdsend for this, but that is why a lot of my servers are
written in bash (hey, it's fun...); you might as well send the
push-command directly from your java-app.
