I have FreeBSD 3.3 server and just had the FreeBSD Java JDK 1.1.8 installed.

I can run the "java" executable from my normal login.   The problem is that when I try to execute the "java" program from within a Perl script and read back the results it is not returning anything.

$PipeMsg = 'java |';
open(JAVACALL, $PipeMsg) || print 'Error opening java call';
while (<JAVACALL>) {
   $RetVal = $_;
   print "<br>Return = $RetVal";
}

This should just retrieve and display the java help output, but nothing is returned, it also doesn't retrieve anything if I pass in a java class and parameters.   Which do work if I run them from the command line, outside the perl script.

What else do I have to configure on the server to get the Perl script to execute the java program?




Best regards,
Ian
