struts codenips
1.
ActionMessage errors=new ActionMessage();
errors.add(“username“,new ActionMessage (“hello.no.username.errpr“));
return errors;
2.
每一个actionBean执行execute方法最后调用return (mapping.findForward("SayHello"));
如果局部的mapping找不到就到全局global forward里面去找.
3.
<html:link forward="BeanServlet">
BeanServlet
</html:link>
<forward name="BeanServlet" path="/BeanServlet.jsp"/>
4.
<bean:cookie id="cookie" name="/tags/cookiedemo" value="firsttime"/>
<%
if (cookie.getValue().equals("firsttime")) {
Cookie c = new Cookie("/tags/cookiedemo", "Hi Linda!");
c.setComment("A test cookie");
c.setMaxAge(3600); //60 seconds times 60 minutes
response.addCookie(c);
}
%>
The cookie value is: <bean:write name="cookie" property="value"/>
