inconsistent output for java process thru perl

[harishram]

Folks,
This is my code snippet. I am running a java process and forwarding the output onto a file.

$mycommand1 = "java -jar cmd.jar -job status -txnid $tid";
$tpid1 = open(OPNTXNPIPE, "$mycommand1 2>&1 |");
open (OUTPUTFILE,">out")
while($line = <OPNTXNPIPE> )
{
print OUTPUTFILE $line;
}
close (OUTPUTFILE);

My problem is that the output file "out" does not give me consistent results, it misses some of the lines from the output.
I get all the lines when the same java command is executed at the shell prompt.

What is missing? Are any of the missing lines a false value in Perl (empty string or zero)? Perl would quit reading at that point. Also, be sure to close your pipe.

Can you repeat the results with a more basic command (something some of us may have around to test with)? What kind of output does the java generate?
