You could, I believe, but AFAIK it's not recommended. The Struts form beans 
are really part of the view layer and should be kept separate from the 
business and persistence layers where possible. A better approach is to use 
a DynaBean for collecting the form data and have the actions copy it into 
the appropriate model class.

Have a look at the commons-beanutils package that comes with Struts. In 
particular, you'll probably find BeanUtils.copyProperties() quite helpful.

Hope that helps,
