[Objectscript-users] using mountJarFile

Hi,

How does one use pkg.system.mountJarFile  ?

I am attempting to instantiate an object of
class com.thoughtworks.xstream.XStream.
The class exists in this jar:

xstream-SNAPSHOT.jar

When I execute these commands:

import "reflection.os";
var file = new pkg.fs.File ( "xstream-SNAPSHOT.jar" );
pkg.system.mountJarFile 	( file );
var com = new JavaPackage ("com" );
var x = new com.thoughtworks.xstream.XStream();


I get this error:

oscript.exceptions.PackagedScriptObjectException:
NoSuchMemberException: no such member: JavaPackage:
thoughtworks


What must be done to mount xstream-SNAPSHOT.jar
and instantiate com.thoughtworks.xstream.XStream ?

Thanks
