<h1>Creating a Generator</h1>

<p>One of the most common types of components to create in Cocoon is to create a
Generator.  Whether you realize it or not, every time you write an XSP page, you
are creating a Generator.  XSP pages do a number of things for you, but there is
a considerable amount of overhead involved with compiling and debugging.  After
all, when your XSP page isn't rendering like you expect and the XML is
well-formed, where do you turn?  You can examine the Java code that is generated
from the XSP, but that can have its own set of challenges.  I had a perfectly
valid Java source file generated for Java 5's javac program, but it wouldn't
compile in Cocoon.  Why?  The default compiler included with Cocoon doesn't
support Java 5.</p>

<p>Sometimes our needs are so simple and so narrowly defined that it would be
much easier for us to create our Generator right in our own IDE using all of the
creature features that are included.  Eclipse and IDEA are both wonderfully rich
environments to develop Java code.  Generators are much simpler beasts than your
transformers and your serializers, so it makes creating them directly even more
enticing.  Cocoon does have some wonderful generators like the
JXTemplateGenerator and others, but we are going to delve into the world of
creating our own.</p>
