Now let's create a PersonManagerImpl class that implements the methods in PersonManager and uses [BeanUtils.copyProperties|http://jakarta.apache.org/commons/beanutils/api/org/apache/commons/beanutils/BeanUtils.html#copyProperties(java.lang.Object,%20java.lang.Object)] 
to convert POJOs &rarr; ActionForms and ActionForms &rarr; POJOs. To do this, create a new class in src/web/**/service and name it PersonManagerImpl.java. It should extend BaseManager and implement PersonManager.
At line 150 added 94 lines.
;:''The [BaseManager|http://raibledesigns.com/downloads/appfuse/api/org/appfuse/webapp/service/BaseManager.java.html] is for registering different Converters (i.e. DateConverter) so that BeanUtils.copyProperties knows how to convert Strings &rarr; Objects.  It currently does not have any convenience methods, but does provide a nice place to add them for all your managers.''

You should be able to compile everything now using "ant compile-web".  Doh!  I guess not:
{{{
PersonManagerImpl.java:11: cannot resolve symbol
    [javac] symbol  : class PersonForm 
    [javac] location: package form
    [javac] import org.appfuse.webapp.form.PersonForm;
}}}
We need to add XDoclet tags to the Person.java Object to create our Struts ActionForm.  In the JavaDoc for the Person.java file, add the following @struts.form tags (use User.java if you need an example):
{{{
* @struts.form include-all="true" extends="BaseForm"
}}}
;:''We extend org.appfuse.webapp.form.BaseForm because it has a toString() method that allows us to call log.debug(formName) to print out a reader-friendly view of the Form object.'' 

Now, running "ant compile-web" should work just fine.
