mapxtreme java新建web项目下servlet问题
我在这个MayServlet.java内写下：import java.awt.Color;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.mapinfo.mapj.MapJ;
import com.mapinfo.mapxtreme.client.MapXtremeImageRenderer;
import com.mapinfo.util.*;
import com.mapinfo.xmlprot.mxtj.ImageRequestComposer;
//import com.myservlets.DoubleRect;
//import com.mapinfo.unit.LinearUnit
import com.mapinfo.dp.*;
import com.mapinfo.dp.util.*;
import com.mapinfo.graphics.*;
import com.mapinfo.mapj.Layer;
import com.mapinfo.mapj.Layers;
import com.mapinfo.mapxtreme.client.MapXtremeDataProviderRef;
import com.mapinfo.mapdefcontainer.MapDefContainer;
public class MyServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public MyServlet() {
super();
}
//输出图片的格式
private static String mimeType = "image/gif";
//定义mdf文件的位置
private static String m_mapPath =
"E: \\MapXtremeJava471\\MapXtreme-4.7.1\\examples\\server\\data\\PCOS-02220523\\guizhou.mdf";
//定义mapxtreme servlet的URL
private static String m_mxtURL
=" http://localhost:8080/mapxtreme471/servlet/mapxtreme";
//实现httpService的doget（）方法
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//设置contentType的类型
response.setContentType(mimeType);
//设置返回响应的输出流
ServletOutputStream sos = response.getOutputStream();
//创建mapJ对象
MapJ m_mapj = new MapJ();
//加载地图
m_mapj.loadMapDefinition(m_mapPath);
//设置地图大小
m_mapj.setDeviceBounds(new DoubleRect(0,0,800,600));
try {
//设置图像请求器（包装mapJ、图片的色位、底色、contentType类型）
ImageRequestComposer irc =
ImageRequestComposer.create(m_mapj,ImageRequestComposer.MAX_COLORS_TRUECOLOR,Color.white,mimeType);
//创建图片渲染器
MapXtremeImageRenderer renderer = new MapXtremeImageRenderer(m_mxtURL);
//用渲染器渲染请求器
renderer.render(irc);
//渲染器输出图片流到输出流，客户端显示之
renderer.toStream(sos);
//释放渲染器
renderer.dispose();
//刷新输出流
sos.flush();
//关闭输出流
sos.close();
}
catch (Exception e){
System.out.println("Error");
e.printStackTrace();
}
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doGet(request, response);
}
}
出现错误：：：：

包已经都易做图去了，有时候建同样的项目好的，有时候就这样出错，哎
--------------------编程问答-------------------- 楼主现在解决了吧，可以交流会吗？
