Hi,
The following is the JavaInputTask.java file
package com.channelpoint.build.ant.publiclib;
import org.apache.tools.ant.*;
import org.apache.tools.ant.taskdefs.*;
import java.io.*;
/**
* This is an enhanced Java task. It can run java programs in another
thread,
* pause while they startup, and give them input.
*
* Arguments include:
* <li>
* <ul>spawn (true or false to create a separate thread for this
execution)
* <ul>sleep (milliseconds to pause before returning)
* <ul>input (nested ex. <input line="blah"/>)
* </li>
*/
public class JavaInputTask extends Java {
private Input _input = null;
private boolean _spawn = false;
private long _sleep = 0;
public void setSpawn( boolean spawn ) {
_spawn = spawn;
}
public void setSleep( long sleep ) {
_sleep = sleep;
}
public Input createInput() {
if( _input == null ) {
_input = new Input();
}
return _input;
}
public void doit() throws BuildException {
super.execute();
}
public void execute() throws BuildException {
InputStream old = null;
if( _input != null ) {
old = System.in;
System.setIn( new ByteArrayInputStream( _input.getBytes() ) );
}
if( _spawn ) {
Spawn s = new Spawn( this );
s.start();
try {
Thread.currentThread().sleep( _sleep );
} catch ( InterruptedException e ) {
throw new BuildException( e );
}
} else {
doit();
}
if( old != null ) {
System.setIn( old );
}
}
public class Spawn extends Thread {
private JavaInputTask _ji;
public Spawn( JavaInputTask ji ) {
_ji = ji;
}
public void run() {
_ji.doit();
}
}
public class Input {
private StringBuffer _buf = new StringBuffer();
public void setLine( String line ) {
_buf.append( line + "\n" );
}
public byte[] getBytes() {
return _buf.toString().getBytes();
}
}
}
the
public void setSpawn( boolean spawn ) {
_spawn = spawn;
}
does exist, but is there a need to use a taskdef task to define the
new class that is to be used??

It doesn't matter how many say it cannot be done or how many
people have tried it before; it's important to realize that whatever
you're doing, it's your first attempt at it.

Subject: Re: how to use a new task
you probably forgot to define a method named setSpawn(Object x) in your
java class.
