I need to be able to pipe a spring configuration file into standard input.
So I have a simple spring program that works when it reads the input from a
file. The spring framework complains when I try to pipe the configuration
file from standard input.
How can I use eclipse to read my config file from standard input so I can
single step thru the spring source (assuming I can figure out how to attach
the spring source to the jar file) and get some clues as to how to alleviate
the problem?
Thanks,
Siegfried
