Running java inside Catalyst

Hi,

Just curious, yesterday I was playing with Java inside Catalyst, and I put a code like:

system("java");

in one of my controllers, and when I accessed the URL, the whole computer: Fedora Core 8, froze and I had to restart. I am not sure whether it is an OS problem, since I later tried the same program on Windows XP with colinux(FC 7)/cygwin and the java ran as expected.

Anyone had a similar experience before ?

Re: Running java inside Catalyst [In reply to]

system function it's a bad idea, if you really need to run Java inside Perl,
i did not try that inside Catalyst, you can check Inline::Java
http://search.cpan.org/~patl/Inline-Java-0.52/Java.pod
I think that will not a problem to use Inline::* inside Catalyst.

Good Luck, and tell us your results.

You do know that Inline::Java uses system() to call java, right?

Re: Running java inside Catalyst [In reply to]

No, i didn't know, i looked at the source and it's true :(
at least Inline::Java it's better than a simple system("java ... ") ?

You can use Java.pm & there are no system calls...

What engine were you running when this happened?

Re: Running java inside Catalyst [In reply to]

Hi,

Not sure which specific engine you asked, but I'll just put all of them.

---
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Server VM (build 10.0-b22, mixed mode)

Linux version 2.6.25.4-10.fc8 (mockbuild [at] xenbuilder2) (gcc version 4.1.2 20070925 (Red Hat 4.1.2-33)) #1 SMP Thu May 22 23:34:09 EDT 2008

This is perl, v5.8.8 built for i386-linux-thread-multi

Catalyst 5.7014

He meant Catalyst engine... Catalyst::Engine::?????

Were you using the server script that comes with Catalyst? FastCGI?
mod_perl?

Re: Running java inside Catalyst [In reply to]

Hi,

I suppose that would be Catalyst 5.7014 ? I checked Engine.pm and there is no "VERSION" there.

I was using the server script that comes with Catalyst. Actually, I wanted to set up my app with Apache(FastCGI), but at that time I just would like to test if my app can call Java apps.
