struts

问题 i am using mvc struts framework in my web application. i am displaying dynamic values from my database in jsp page using scrilets <% %> its been bad practice doing that way but i followed links of how to do it without scriptlets but cant understand much ..i am using struts and i have action and bean class this is my jsp page <%@page import="java.sql.ResultSet"%> <%@page import="com.pra.sql.SQLC"%> <%@page import="java.util.ArrayList"%> <%@page contentType="text/html" pageEncoding="UTF-8"%>

问题 I face this problem. I have a filter that sets the character encoding of the request according to the filter's config (for example, to UTF-8). This works with forms coded using the struts html:form tag. However, if I use the ordinary HTML form tag, the data are not encoded correctly.

问题 Hello i have an url in my jsp and i want to pass an array of string in this url to recover in my ActionForm 回答1: You can use 'standard' html way of passing arrays of data: http://mywebsite/mypage?myarray=value1&myarray=value2&myarray=value3 . Then you can fetch all values of parameter myarray from request object (if framework doesn't provide more elegant ways of handling arrays). But seeing your comment, I would recommend to leave JavaScript and just declare a form for it. If you need a link

问题 I am a newbie in web development. I'm using servlets and JSP for web development.However, I've learnt lately that Spring Framework is apt for that which incorporate servlets, jsp etc. So, my question is that can I now run my program using Spring framework ? Like, I have 2 jsp codes, and 1 servlet class. So, how can I migrate the code in Spring Framework ? what additional things or codes do I need to maintain ? 回答1: Migrating an existing J2EE project is easy. You will get rid of a lot of

问题 Problem and my idea on it is just vague as I'm still in design phase. I just wanted to know something to get a head start on the problem and how/where to proceed to solve it.
