Make sure the application can call
the java compiler and you have the jsf-api.jar
library in the <current>/lib/
directory.
You forgot to include the path to the
faces servlet in your URL. Therefore JSF doesn't find its controller.
It should look like: http://myhost/MyForm.jsf
(if you use the standard URL pattern *.jsf).
Put your changes in a derived class
of the backing bean and change the faces-config.xml
(<managed-bean> section) to use it
instead. Then you can safely recreate the backing bean without
loosing your changes. As long as you don't change the old fields it
should still work.
The FormBuilder uses Velocity
to generate the files. The template for the Java backing beans is
stored in templates/bean.java.vm and for
the JSPs in templates/form.jsp.vm.
Please see the Velocity
tutorial on how to adapt the templates for your own project.
