Config Struts-menu in application

freefly — Wed, 05 Apr 2006 07:23:00 GMT

Background

         Usually,When we develop our web application,we need create menu.We can use Javascript to design web menu,but if thus,we have to compile many codes,and our application hasn't good revisability and maintainability .Struts-menu provides us a convenient web menu design way,we can put our web menu data in  a menu-config.xml configuration file,and read the data with struts-menu lable.

   2.  Struts  Menu Example

        You can go here http://demo.raibledesigns.com/struts-menu/ to see the example;
        Or download the example application :struts-menu-2.3.zip,follow the below instruction:
              Unzip it to a local directory.
               Download and install Tomcat or another Java Servlet container.
              Put struts-menu.war in Tomcat's webapps folder and start the server.
               Go to http://localhost:8080/struts-menu

3. Integrating Struts Menu into your application

      1. Place struts-menu-2.3.jar into your app's WEB-INF/lib directory.(maybe you also need put common-lang.jar)
      2.  Place struts-menu.tld,and struts-menu-el.tld into your app's WEB-INF directory
      3. Copy the common,images,scripts,template,styles directory from the above struts-menu.war exmaple application to your web directory.(if use Myeclipse,put those directorys in webroot directory)
      4. Add the plug-in settings to your struts-config.xml file.


                                                              value="/WEB-INF/menu-config.xml"/>


        5. You will need to declare your menu's attributes in a your App /WEB-INF/menu-config.xml file.Here's  a short snippet of what might look like:

         6.   Add a taglib declaration to the top of your JSP:

        <%@ taglib uri="http://struts-menu.sf.net/tag" prefix="menu" %>

       7. Add taglib code to render your menu in your JSP:

                                  bundle="org.apache.struts.action.MESSAGE">




       8. Below is a whole test.jsp
           <%@ page contentType="text/html; charset=UTF-8" %>
           <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
           <%@ taglib uri="http://struts-menu.sf.net/tag" prefix="menu" %>



                menu


                                                     href="styles/global.css" />
                                                  href="styles/coolmenu.css" />








                                bundle="org.apache.struts.action.MESSAGE">

solution for mess code in struts+spring+hibernate+mysql4.1

freefly — Thu, 23 Mar 2006 05:07:00 GMT

Here is my solution for mess code on page,hope this can help you!
The point is your database coding should be consistent with the coding of character that you plan to insert into the database.
Attention: Here,I take "UTF-8" as default character coding way .
There are three steps:
1. set page charset
     e.g      <%@ page language="java" contentType="text/html; charset=UTF-8" %>

2. create character filter:
     package com.victory.util;

     import javax.servlet.http.HttpServlet;
     import javax.servlet.Filter;
     import javax.servlet.FilterConfig;
     import javax.servlet.ServletException;
     import javax.servlet.ServletRequest;
     import javax.servlet.ServletResponse;
     import javax.servlet.FilterChain;
     import javax.servlet.http.*;
     import java.io.IOException;
   public class CharacterEncodingFilter
      extends HttpServlet
     implements Filter {

private FilterConfig filterConfig;
private String targetEncoding = "ASCII";

   /**
     * Called by the web container to indicate to a filter that it is being placed
      * into service.
    *
     * @param filterConfig FilterConfig
     * @throws ServletException
    * @todo Implement this javax.servlet.Filter method
     */
     public void init(FilterConfig filterConfig) throws ServletException {
      this.filterConfig = filterConfig;
    this.targetEncoding = filterConfig.getInitParameter("encoding");
     }

    /**
     * The doFilter method of the Filter is called by the container
    * each time a request/response pair is passed through the chain due to a
     * client request for a resource at the end of the chain.
    *
   * @param request ServletRequest
   * @param response ServletResponse
    * @param chain FilterChain
   * @throws IOException
   * @throws ServletException
   * @todo Implement this javax.servlet.Filter method
   */
   public void doFilter(ServletRequest srequest, ServletResponse sresponse,
                       FilterChain chain) throws IOException, ServletException {
     try {
      HttpServletRequest request = (HttpServletRequest) srequest;
      request.setCharacterEncoding(targetEncoding);
       chain.doFilter(srequest, sresponse);
         }
     catch (ServletException sx) {
       filterConfig.getServletContext().log(sx.getMessage());
        }
      catch (IOException iox) {
       filterConfig.getServletContext().log(iox.getMessage());
       }
    }

   /**
    * Called by the web container to indicate to a filter that it is being taken
    * out of service.
     *
    * @todo Implement this javax.servlet.Filter method
    */
    public void destroy() {
     filterConfig = null;
     targetEncoding = null;
    }
}

  3.config web.xml
    attention: add these to your web.xml

     EncodingFilter
     com.victory.util.CharacterEncodingFilter

       encoding
       UTF-8



    EncodingFilter
    /*

  4.set database configration
     modify the file:    my.ini
     [client]     default-character-set=utf8
     [mysqld] default-character-set=utf8
  5.restart Mysql server
6.modified your table coding way to utf8
     or ceate your table like this :
     CREATE TABLE `user` (
   `ID` int(11) NOT NULL auto_increment,
    `USERNAME` varchar(50) NOT NULL default '',
   `PASSWORD` varchar(50) NOT NULL default '',
PRIMARY KEY (`ID`)
    ) ENGINE=MyISAM DEFAULT CHARSET=utf8;
7.restrart your tomcat sever

OK,it's all.

   Authrougn I have sovled   my problem, I think I  don't have enough understanding for it,  So hope    communicate with you!

Attention:mess code also exist in your database,through page hasn't mess code.
