帮助创建操作类（java）

Question

嗨，我有一个jsp在下面：

    <form action="testPage.do" method="post" name='testForm' id="testForm">


    <h2><bean:message bundle="test" key="label.header1"/></h2>

    <p><bean:message bundle="test" key="label.dropdown1/> </label>

    <select>
        <option selected="selected">Soccer</option>
        <option>Football</option>
        <option>Baseball</option>
        <option>Hockey</option>
    </select>
    </p>


    <p> 
    <label><bean:message bundle="test" key="label.firstName"/> </label>
    <input type="text"" name="firstname">
    </p>

    <p> 
    <label><bean:message bundle="test" key="label.lastName"/> </label>
    <input type="text"" name="lastname">
    </p>


    </form>

我正在尝试创建一个action类，它将为我填充下拉菜单，并获取输入到名字和姓氏文本框中的值。 对于动作类，我有：

public class SportAction extends BaseAction {


    public ProcessResult executeFirstTimeInLogic(ActionMapping mapping,
                    ActionForm form, HttpServletRequest request,
                    HttpServletResponse response,
                    ProcessResult processResult) throws Exception {
            log.info("executeFirstTimeInLogic");
     processResult.setForward(mapping.findForward("next"));
     return processResult;
    }

    public ProcessResult executeSubmitLogic(ActionMapping mapping,
                    ActionForm form,
                    HttpServletRequest request,
                    HttpServletResponse response,
                    ProcessResult processResult) throws Exception {
            log.info("executeSubmitLogic");

             return processResult;
     }

}

如何创建方法来将值输入文本框，以及如何创建方法来填充action类的下拉菜单
