Re: ClassCastException com.dev.model.Form cannot be cast to java.lang.String
Look at your execute() method or whatever method you're calling from your
JSP. I suspect that you are returning a com.dev.model.Form object instead
of a String like success or input.

2009/3/24 foward fow...@gmail.com:
the method getForm() return a object Form where before with the respective
id is obtained and returned.
You put method getForm() in s:form as a action, which means such
method will be called by Struts 2 and the framework will expect a
String - result name, which you have to define in struts.xml.
You shouldn't return an object like Form. To do that, implement
ModelDriven interface and return your Form object from method
getModel() and in your jsp use ${name} instead ${form.name}
Yes I m reading a book struts in action, I don't know if you recomend me a
good one.
That is good one

What's utente?
In any case, you don't say where the exception is, but
for whatever reason your DAO isn't getting a user (if
that's where the exception is).

RE: ClassCastException when usig multiple web applications
definition name=baseDef path=/am/WEB-INF/pages/mainLayout.jsp

change your tile-defs to not include the context name of your application ie
definition name=baseDef path=/WEB-INF/pages/mainLayout.jsp
put name=menuPanel value=/amMenupanel.jsp/
Also, why place your jsp's under WEB-INF ? Is there a security concern you are trying
