<a name="appgen"></a>__The AppGen Tool__

As part of 1.6.1, I created an __AppGen__ tool that can be used to generate all the classes for the rest of these tutorials. This tool was based on contributions from [Lance Lavandowska|https://appfuse.dev.java.net/issues/show_bug.cgi?id=60] and [Ben Gill|https://appfuse.dev.java.net/issues/show_bug.cgi?id=78]. At first, I didn't want to add a code-generation feature like this b/c you'd end up with a 1-to-1 relationship between tables/pojos, DAOs and Managers. On most of my projects, I have far fewer DAOs and Managers than POJOs.

By default, AppGen will generate only Actions/Controllers, Action/Controller Tests, test data, i18n keys and JSPs. It will also configure Actions/Controllers for you. It uses the generic BaseManager and BaseDaoHibernate classes (configured as "manager" and "dao") to reduce the number of files that are generated. However, I realize that sometimes you will want to generate all the DAO and Manager classes (as well as their tests), so I've added that option too.

To use the AppGen tool (after installing your web framework), perform the following steps:

# Create your POJO (in the model directory) and <a href="#ref-CreateDAO-5">configure the mapping file</a> in applicationContext-hibernate.xml.

# cd into the ''extras/appgen'' directory and run "ant -Dobject.name=Person -Dappgen.type=pojo". In this example, the __Person__ class should exist in your "model" package. This generates all the files you create in the tutorials on this site (for your chosen web framework).

# To install the generated files, run "ant install". You can run "ant install -Dmodel.name=Person -Dmodel.name.lowercase=person" if you want to do everything in one fell swoop. __WARNING:__ You might want to backup your project before you do this - or at least make sure it's checked into a source code repository. I've tested this code, and I think it works well - but it ''is'' modifying your source tree for you.

The reason for the "lowercase" parameter is to rename the JSPs to begin with a lowercase letter. If I tried to rename them and change the filename programmatically, it took 1MB worth of BSF and Rhino JARs (+5 lines of code) and this just seemed easier. Speaking of JSPs - it's up to you to modify the *Form.jsp and make it look pretty. This is covered in Step 5 of each respective web framework's "Create Action/Controller" tutorial: <a href="http://raibledesigns.com/wiki/Wiki.jsp?page=CreateActions#ref-CreateAction-5">Struts</a>, <a href="http://raibledesigns.com/wiki/Wiki.jsp?page=SpringControllers#ref-SpringControllers-5">Spring</a> and <a href="http://raibledesigns.com/wiki/Wiki.jsp?page=WebWorkActions#ref-WebWorkActions-5">WebWork</a>.

__NOTE:__ If you'd like to generate all the DAOs/Managers/Tests, run "ant install-detailed" instead of "ant install". Before you install anything, the files will be created in the extras/appgen/build/gen directory (in case you want to look at them before installing). If you just want to test the tool, you can cd to this directory and run "ant test" to see the contents of these tutorials created.

I encourage you to read these tutorials even if you decide to generate all your code. That way you'll understand what's being generated for you and you'll only need to mailing list for [asking smart questions|http://www.catb.org/~esr/faqs/smart-questions.html]. ;-) Hopefully this tool will remove the pain of writing simple CRUD code and let you concentrate on developing your business logic and fancy UIs!</div>
