Exange of informations and objects between PERL and JAVA

[Lionel]

Hi all,

I would like having more informations on how we could exchange
informations and/or objects between PERL and JAVA.

We have a Java programs that open, maintain and close telnet
connections, for PERL scripts...

Is it possible, to echange the Java telnet session object to PERL
programs ? Or thoses two languages could not exchange objects or such
structure ?

If it's not possible, how could I exchange textual informations
between a Java program and a PERL script on the same UNIX computer ?
Socket, Pipe,... ?

Or mayby, there is another solution ?

Thanks a lot for your help.

Best regards.

Lionel.

That is obvious from the excessive
cross-posting to the groups..
comp.lang.java,
comp.lang.java.api,
comp.lang.java.developer,
comp.lang.java.help,
comp.lang.java.misc
...most of which are invalid.

As well as to the multi-posted messages to
comp.lang.java.programmer and comp.lang.java.tech.

Please
a) do not cross post.

b) do not mutli-post

c) choose the single group to which you post
from a list of valid groups, such as..
<http://www.physci.org/codes/javafaq.jsp#groups>

*Note*, follow-ups set to the only appropriate
group in this circumstance, c.l.j.help..

You could, maybe, use a FIFO. If the Java application is getting data
via telnet and then using the Perl script to parse the data, you could
just write to a FIFO from the Java application and let the Perl script
read the data coming into the FIFO. This, of course, opens up a host of
issues (such as the fact a FIFO isn't like a regular file, so reading
isn't done the same way as with a regular file - it's done with an
infinite loop).

Just a question for you to ponder .... why not just use one or the other
language? Regular expressions were introduced to Java in version 1.4
and Perl has the Net::Telnet module to open, read, and close telnet
connections. Seems like a lot of extra work if you have the question
you have asked. :-)
