How to use stdin/stdout with exec
I am using Ant to automate the creation of some Java classes and compile
them. I also want to be able to execute one of these generated Java classes
(which has a builtin command processor). The commands are entered by the
user (interactively) and the output is sent back to the console (via
System.out).
I simply want to use either the JAVA or EXEC task to invoke the class, but I
can't get the stdin and stdout to be routed to the class. I can see lots of
ways to wire up the input/output to files, but no way to have them wired
back to the Ant console. Am I missing something? Without specifying
anything, I don't see anything and can't enter anything. Is there a way I
can specify the console/terminal in Windows using the input and output
attributes?
I am using Ant 1.6.5 on Windows.

Urgent : Send me some Initial Docs
Posted by Vipin Batra <vb...@coulera.com>.
Hello all !
I am a new user to the group. I wanna use ANT for automated testing (In
Webservices). Please send me the Initial docs on ANT covering all the basics
and Examples.
I need to understand the use of ANT with examples so that I am able to
bridge my project.
Thanks in advance,
Vipin Batra.

Re: How to use stdin/stdout with exec
Posted by toadFrog <ke...@comcast.net>.
I read through all the responses to your question. I saw nothing that
addressed this.
Your question addresses an issue with is the same problem as running a KSH
interactive script from the ant exec command. Specifically, ant does not
block for user input when a script executes a read command ,at least,
using the following configuration:
ant build.xml snippet:
<target name="promote" depends=""
description="Usage: ant promote">
<echo message="running: build-promote.sh"/>
<exec
dir="${clearance.dir}"
spawn="false"
executable="/bin/ksh">
<arg line='-c "build-promote.sh < $STDIN"'/>
</exec>
</target>
ksh: build-promote.sh snippet:
echo
echo "Select kit number: "
typeset -i akit
read aKit
echo "Is this kit number ok? $aKit"
Upon execution of the read command, ant must stop and allow the user to
enter a response. Instead what is happening is execution continues with the
next line in the shell pgm. I can't enter a response to any of the reads in
the pgm.
Seems this is just operator error on our part. But, I've messed around with
this too long and tried several different approaches.
Were you able to get this working?
thx in advance. kev.
