jboss riftsaw installation problem

Hi, i'm new to this jboss riftsaw. Actually while Installation JBoss BPEL Runtime. i tried to deploy by giving a command like this
"D:\riftsaw-2.1.0.Final\install>ant deploy -Ddatabase=mysql -Dws.stack=native -Dws.version=3.2.2.GA" as mentioned in the JBoss BPEL User Guide.
But i'm getting a error as mentioned below.
