Re: Perl won't Open() when called from Java

How do you determine it hangs in the open? What happens if you add a die statement right after your open?

I don't know what you are doing inside your while loop, but if you aren't printing enough so your buffer gets flushed, you won't see anything. And normally speaking, your while loop will never terminate; if you actually don't print to STDOUT from there, you will never see the output of your print statement.

Perhaps you should turn off buffering.

Buffering was actually the problem. I assumed it was hanging but really it just wasn't showing any output for the print. Thanks. For others, this was solved by adding `$\|=1;` to my code to disable buffering	[reply] [d/l]
