Is there a way I can do console redirection when I run my Java class
files within Eclipse. For example, I want to use a file called
input.txt as my standard input, but typing "< input.txt" in the program
arguments section of my java application configuration doesn't seem to work.
Thanks,
-mike

To use java instead of javaw:
See the JRE Tab for your launch configuration.
Specify to launch in an Alternate JRE and then you are able to specify the
Java executable that will be used.
