MapInfo的web发布——长征第一步

最简单的web页面显示地图，eclipse + jsp + MapInfo mapxtreme
1、打开eclipse，建立tomcat工程，将mapxtreme安装目录下的lib目录下的三个文件夹（client，comments，server）里面的文件（注意是文件，不要连文件夹一起拷贝）拷贝到刚才建立的工程目录下的WEB-Info/lib目录下，在eclipse中右击工程名——》属性——》javabuliderpath——》labraries，点击add external jars，将刚才拷贝的文件全部选择，添加到工程的工程的应用中

2、建立MakePNG类：

Code

3、建立输出图片的servlet：

package Map;
2

import java.awt.Color;
4

import java.io.IOException;
6

import javax.servlet.http.HttpServlet;
7

import javax.servlet.ServletException;
8

import javax.servlet.http.HttpServletRequest;
9

import javax.servlet.http.HttpServletResponse;
10

import com.mapinfo.mapj.MapJ;
12

import com.mapinfo.mapxtreme.client.MapXtremeImageRenderer;
13

import com.mapinfo.xmlprot.mxtj.ImageRequestComposer;
14

public class outMap extends HttpServlet {
15

static final long serialVersionUID = 1L;
16

/* (non-Java-doc)
17

* @see javax.servlet.http.HttpServlet#HttpServlet()
18

*/
19

public outMap() {
20

super();
21

}
22

/* (non-Java-doc)
24

* @see javax.servlet.http.HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
25

*/
26

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
27

// TODO Auto-generated method stub
28

response.setContentType("image/png");
29

MakePNG mp3 = new MakePNG();
30

MapJ mj = mp3.initMap();
31

String mjHttp = "http://localhost:8080/mapxtreme471/servlet/mapxtreme";
32

MapXtremeImageRenderer mxir = new MapXtremeImageRenderer(mjHttp);
33

try{
34

mxir.render(ImageRequestComposer.create(mj, ImageRequestComposer.MAX_COLORS_256, Color.white, "image/png"));
35

mxir.toStream(response.getOutputStream());
36

}catch(Exception e){
37

e.printStackTrace();
38

}
39

}
40

/* (non-Java-doc)
42

* @see javax.servlet.http.HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
43

*/
44

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
45

// TODO Auto-generated method stub
46

this.doGet(request, response);
47

}
48

}
49

4、建立用于显示地图的jsp页面：

1 <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
2 pageEncoding="ISO-8859-1"%>
3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
4 <html>
5 <head>
6 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
7 <title>Insert title here</title>
8 </head>
9 <body>
10 <img src="outMap">
11 </body>
12 </html>
13 <%
14 out.println("hello money");
15 %>
