STRUTS2 project, JSP page form submission

Recently wrote a simple registration page, but after submitting the form, the program did not invoke the corresponding action, but the submitted parameters are displayed in the URL address bar.

Detection of the half-day code, action various configurations are not wrong, but how to invoke the program did not call their own action, and finally carefully detect the JSP page found that

There is actually a form outside of your form form, which leads directly to the action you want after the submit, instead of invoking the form outside,

The parameters submitted by the form are passed to the URL address bar.

How careless mistake, this shows, usually write code must be serious!!!!
