The following example shows the usage of ActionForm to accept values from the web page and process them.
package org.mybusiness.strutstutorial.forms; import org.apache.struts.action.ActionForm; public class AddUserForm extends ActionForm { private static final long serialVersionUID = 1L; private String userId; private String password; private String name; public String getUserId() { return userId; } public void setUserId(String userId) { this.userId = userId; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
AddUserAction.java
package org.mybusiness.strutstutorial.actions; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.struts.action.Action; import org.apache.struts.action.ActionForm; import org.apache.struts.action.ActionForward; import org.apache.struts.action.ActionMapping; import org.mybusiness.strutstutorial.forms.AddUserForm; public class AddUserAction extends Action { @Override public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { AddUserForm userForm = (AddUserForm) form; System.out.println("User ID : " + userForm.getUserId()); System.out.println("User Name : " + userForm.getName()); return mapping.findForward("SUCCESS"); } }

The Struts html tags are used to get inputs from the user.
