我想把JSP中JAVA片段得到的值通过超连接或者提交按钮传到对应的ACTION类中 怎么实现?(有代码片段)

<% String s = (String)request.getAttribute("idd");  %>
        <html:form action="/update?iddd=  " >
        <bean:message key="xingming" /><html:text property="xingming" />
            <html:errors property="xingming" />
            

            <bean:message key="dianhua" /><html:text property="dianhua" />
            <html:errors property="dianhua" />
            

            <bean:message key="dizhi" /><html:text property="dizhi" />
            <html:errors property="dizhi" />
            



            <html:submit />
            <html:cancel />
        </html:form>
