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.
