32 * This is my example of a class that writes a list of a service's
33 * ports to a file named <serviceName>Lst.lst.
34 *
35 * Note: because of a name clash problem, I add the suffix "Lst".
36 * I hope to remove this in a future version of this example.
37 *
38 * Details of the JavaWriter bug: JavaWriter looks to make sure a
39 * class doesn't already exist before creating a file, but not all
40 * files that we generate are .class files! This works with
41 * deploy.wsdd and undeploy.wsdd because these files just happen
42 * to begin with lowercase letters, where Java classes begin with
43 * uppercase letters. But this example shows the problem quite
44 * well. I would LIKE to call the file <serviceName>.lst, but
45 * JavaWriter sees that we already have a class called
46 * <serviceName> and won't let me proceed.
