Along with adding compiled code in the form of classes and JARs, a module should also contain any other resources needed for utilizing the code. As I stated at the beginning of this chapter, many modules do not contain any compiled code, but are made up entirely of documents, templates, and JSP pages. As we've seen in Chapter 4, adding content to a module is no different than adding content to any other location in the VFS. Simply stated, anything that exists in the module's directory (in this case /system/modules/com.example.genericxml.xslt/) will be exported with the module. It is also possible to attach content in other parts of the VFS to the module, and we will do that in the Managing the Module section later.

Before we get to that, though, we will create some XML content to transform, the XSLT stylesheets for transformation, and a JSP page that will do the transformation, using the class we just created.
