本文介绍了如何在Struts框架中配置form-bean及action-mapping，包括具体的XML配置示例。通过这些配置，可以实现表单数据传递及业务逻辑处理。

You will need to add the Action mapping in your struts-config.xml file.
You
will also need the form-bean mapping that your form will use to pass the
form data to the action class.

Here is an example.

<form-beans>
    <!-- Loin form bean -->
    <form-bean      name="loginForm"
                    type="com.dextera.examples.forms.LoginForm"/>
</form-beans>

<action-mappings>
    <!-- Process a user login -->
    <action    path="/login"
               type="com.dextera.examples.actions.LoginAction"
               name="loginForm"
              scope="request"
              input="/login.jsp">
       <forward name="success"              path="/home.jsp"/>
</action-mappings>

All in all you will need the following:

1. A form bean to carry the data
2. Action servlet to perform your action
3. Form bean declaration in struts-config
4. Action mapping in struts-config

if you modify the struts-config.xml,restart tomcat5
Good luck.
