Got it. Yah you currently can't pass binary data over the JavaServer connexion.
Other than encoding the data (base64 would be easy), you can open a socket
between the JavaServer process and the perl process & pass the data that way.
Check out 'sever.pl' in the perl examples - a ServerSocket & created &
opened on the Java side & then lines are passed to it - all from within perl.
Mash your ByteArrayInputStream on top of the ServerSocket & you may have
something.

Mark,
My Java objects are zipped together in a zip file. I use perl to
iterate through the entries. For each entry I have an $entry->contents
that I want to pass to the Java side. My original workaround was to
write the contents out to /tmp. That doesn't work when I'm not on the
same machine as the Java server.=20
I could uuencode the contents and pas them over, but then I
would have to write more Java code than I want to. All I really want to
do is:
my $bis =3D $java->create_object("java.io.ByteArrayInputStream",
$entry->contents);
my $str =3D $java->create_object("java.io.ObjectInputStream",
$bis)->readObject->toString();

I don't know what you mean here. You want de-serialize java objects right?
Why not just have the Java side do it?

Just one or two objects, but I'm using the server as a catch-all. So I am running multiple short-lived scripts against it, with large gaps of downtime. The trouble usually occurs after a couple of days of usage. Matt |

Hey Matt,
I have thought about switching to an XML-protocol - SOAP/XML-RPC/roll
my own/even jabber. Unfortunately those things take time I just don't have.
However if you'd like to step up I won't stop you!
I have never tried passing binary data but I am sure the protocol would
get in the way - you could uuencode the data & then send that over - & just
have the Java stuff uudecode it & be back in business.
There currently is no way to dump the cache - although I think it would
be quite easy to implement - a better solution is to figure out what it's
getting confused! What platform are you running on & how many objects are
you creating & how long does it run before there's trouble?
thanks,
Mark

Hi, I'm trying to use JavaServer to read an ObjectStream. I'd like to open the file on the perl side and send the binary data across to the server as a blob. Is there anyway to do this at the moment? I played around for a bit and it looks like the protocol is getting in the way... This leads me to question number two. Any plans to move to, say, XML?=20 I also noticed that after running for a long period of time, my JavaServer gets 'confused' restarting it always solves the problem, is there anyway of dumping the cache on the server?

d'oh - sorry about that. Debug.java is available from sourceforge CVS
& will be included in the next release (it hasn't changed since the 5.1
release).
Is that sufficient or do you need a whole new tarball?

I noticed the other week that the 5.1 source tarball doesn't contain Debug.java, could you please regenerate the tarball to include it, for those of us who like to compile things ourselves? Thanks, Dave |
