XDocletActionForms

1. Even after creating this <actionform> task, I found that Hibernate doclet still seemed to need XDoclet's ejb module in the classpath. This is because the apache module has references to a bunch of tasks that depend on EjbDoclet. Removing these tasks when building is a workaround, but adding the xdoclet-ejb module to the classpath is the easiest solution.

2. If using Ant 1.5.x, and you're using Struts, you will get the following error when you run "ant compile" with 1.5.

    compile-web:
       [xdoclet] (XDocletMain.start                   47  ) Running 
    <actionform/>

    xdoclet.TemplateSubTask.generateForClass(TemplateSubTask.java
    :751)

3. If I define the "xdoclet" task inside the "compile-web" target, it will work, but only when I call that target explicitly. When I make another target depend on it, I get the following error with Ant 1.5.x.

    file:c:/Source/appfuse/build.xml:779: Class 
    xdoclet.modules.apache.struts.Action
    FormSubTask doesn't support the nested "packageSubstitution" element.

5. My final solution: Move the xdoclet/actionform task into it's own target and prevent it from executing if it doesn't need to.

Below is a list I created while comping up with a solution.
