As you've seen, the dynaClass is required before you use a
DynaActionForm. The dynaClass is what tells BeanUtils what properties
your DynaActionForm has. To create a DynaActionForm with the
DynaClass initialized, call formBeanConfig.createActionForm(). You
can get a formBeanConfig instance through
ModuleUtils.getInstance().getModuleConfig(request).findFormBeanConfig("formName").
