Hi,
I've finally figured it out.
In order to link the form with the servlet, you have to map the
servlet in web.xml. It is similar to writnig the struts-config.xml
file.
After putting the servlet info there, you just need to pass the
servlet url in the form action, and on submit you will end up with the
execution of the servlet.
