RE: How can I run Batch file from servlet ??

[Randy Layman <ra...@aswethink.com>]

	When you create a process like this, its up to you to read and write
to the process.  This means that any output from your batch file will be
lost unless you deal with is (Process has methods to get the input and
output streams for standard in/out/error).

	I would suggest you try running your batch file from the tomcat's
home directory.  The problem is usually one of two things.  Either you have
relative paths which aren't valid in the current context or you are
expecting environment variables that aren't valid.  (Or possibly its
actually working but you aren't catching the batch file's input to know
that).
