Java with apache from perl script?

[i5513]

Hi, I'm running Apache server with mod_perl active.

I can run my script from command line and all is fine, but when I run
my script from navigator, it doesn't run fine because my script is:

....
system "java program_java";
....

How can I do Apache to run java programs?

Thanks you, I read on google about Tomcat and about Apache Jserver,
but I don't know where can I start.

PD: I'm sorry for my poor english.

Not like that. Not, in fact, using Perl at all.

Start in an Apache or Java newsgroup.

Why not? It just looks like "java" isn't in the CGI process's $PATH...
Since the OP's script runs from the command line but not the browser,
I'd recommend the troubleshooting links in the FAQ.

% perldoc -q 500

If you want to have a Java Applet server, visit:

http://jakarta.apache.org/tomcat/index.html

You _could_ use Perl to execute a Java application, but IMHO it would
be better to use an actual Java server to perform the task.

CGI is run under a special user with restricted rights and
an empty path variable.

You should always, yes *always* check the results
of system operations and return the error ($! for
internal processes, $? for daughter process).

Give it the full path to java and the program.

my $java = '/full/path/to/java';
my $program_java = '/full/path/to/program_java';
system ($java $program_java) == 0 or die $?;

Thanks you, my 'particular' problem was the classpath.

I solved it with:
$Output = qx/"java -cp /full/path/to/classes
/full/path/to/program_java"

on my local apache it seems like perl had C:\winnt\system32 on
$ENV{PATH}. Java.exe was on winnt\system32 ... I think my perl script
isn't a CGI program where you says path is empty.

Thanks you again.
