NOTE: In order to run this tutorial you will first need to install the java example available at Downloads. If you don't have a Java server, then start with the Writing Servers part and change the access url from the client accordingly.
First we will write a Hessian client that calls a Java service, then we will write and publish a service. The assumed Hessian Java service returns simple user information. This service exposes a method called findUser() which takes a username and returns an object of type User that contains user information or null if user is not found.
