[Steve Morrow]

static String oneWay() {
java.util.Random rand = new java.util.Random();
StringBuilder buf = new StringBuilder();
for (int i = 0; i < 6; i++) {
buf.append(rand.nextInt(10));
}
return buf.toString();
}
static String anotherWay() {
java.util.Random rand = new java.util.Random();
int result = rand.nextInt(1000000);
return String.format("%1$06d", result);
}
// I'm sure there are plenty others...

Have the appropriate service method (doGet() or doPost(), for example) call the the random-number generating method; that's all there is to it.
