I have a jar file which contains several classes that have contained in them. This code is 'attached' to another far bigger application which runs a Swing GUI but doesn't have a DOS window. Is it possible that having these System.out.printlns could cause a problem when they are reached - because there's nowhere to write to. At least nowhere that I can see. I don't have any way of making the GUI application launch a DOS window. Thanks. Paul
As far as I know, these are not a problem; the Swing GUI is probably running by invoking javaw instead of java (the latter has a command prompt, the former does not), and I've never had any problems with my printlns.

In your case i would use a logging framework like log4j or logkit (based on log4j) there you can easily set up logging into a file. (You see log4j in all App Servers and most of the tools) It is a jakarta framework which you can findhere There you can write to so called appenders (console, syslogd, file etc.) Olli [ June 06, 2003: Message edited by: Oliver Refle ]
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
