This is being done with help of interceptors, struts2 provides a set of
interceptors to do some work for you and transferring form values to
actions properties is one of them.
Have a look at
http://struts.apache.org/release/2.3.x/docs/parameters-interceptor.html and
see how this interceptor will work.
This is responsible for transferring data, also there will be type
convertors in place which will convert String values being sent form form
to desired data types.
Have a look at
http://struts.apache.org/release/2.3.x/docs/struts-defaultxml.html
to see what all interceptors are configured.
See also http://struts.apache.org/release/2.3.x/docs/interceptors.html to
get more understanding about them.
