I wouldnt start java programs via exec.
I modified the tutorial example a litte bit.
Basically you iterate with AntContrib over the JARs and start them via <java>.
Jan
/src/oata/HelloWorld.java
package oata;
public class HelloWorld {
public static void main(String[] args) {
// Tutorial modified for printing the current location/actual JAR
java.net.URL location =
HelloWorld.class.getProtectionDomain().getCodeSource().getLocation();
System.out.println(location);
}
}
/build.xml

Well, there are several ways to do what you want. I'll show you just one of
these ways, I'm using it:
It's my build.xml, it's only a sample, okay ?
<?xml version="1.0"?>
<project name="Prova" basedir=".">
<target name="run">
<antcall>
<target name="taskServer"/>
<target name="taskClient"/>
</antcall>
</target>
<target name="taskServer">
<exec executable="java" spawn="true">
<arg line="-jar"/>
<arg value="EmployeeServer.jar"/>
</exec>
</target>
<target name="taskClient">
<exec executable="java" spawn="true">
<arg line="-jar"/>
<arg value="EmployeeClient.jar"/>
</exec>
</target>
</project>
You can use a lot of options and parameters to customize the behaviors of this
sample build.xml.
I hope this can give you some hints
Bye
Virgilio
