tomcat转到weblogic

51qsx

1. 用XmlHttp获取xml，responseXml为空。
  
   解决方法：
   在web.xml中加入
   <mime-mapping>
      <extension>xml</extension>
      <mime-type>text/xml</mime-type>
   </mime-mapping>
   <mime-mapping>
      <extension>xsl</extension>
      <mime-type>text/xml</mime-type>
   </mime-mapping>

2. 用SmartUpload下载文件时出错   
   出错信息：
   java.io.IOException: 文件名、目录名或卷标语法不正确。
        at java.io.WinNTFileSystem.canonicalize0(Native Method)
        at java.io.Win32FileSystem.canonicalize(Win32FileSystem.java:395)
        at java.io.File.getCanonicalPath(File.java:531)
        at weblogic.servlet.internal.WebAppServletContext.getRealPath

        解决方法：自己写了一个Servlet来下载文件，代码如下：
  

 1 public class DownLoad extends HttpServlet
 2 {
 3     private static final long serialVersionUID = -84138329260803824L;
 4     public void init() throws ServletException
 5      {
 6     }
 7
 8     public void doGet(HttpServletRequest request, HttpServletResponse response) 
 9         throws ServletException, IOException
10      {
11         OutputStream os = null; 
12         FileInputStream fis = null;
13         try
14          {            
15             String fileName = request.getParameter("filename");  //要下载的文件,包括路径
16             String downFileName = fileName.substring(fileName.lastIndexOf("\\") + 1); //去掉路径
17             
18             os = response.getOutputStream();
19             File f = new File(fileName);
20             
21             response.setHeader("Content-type:", "application/octet-stream");
22             response.setHeader("Accept-Ranges:", "bytes");
23             response.setHeader("Accept-Length:", Long.toString(f.length()));
24             response.setHeader("Content-Disposition", "attachment; filename=" + downFileName);
25                 
26             fis = new FileInputStream(f);
27             byte[] b = new byte[1024];    
28             int i = 0;    
29             while((i = fis.read(b)) > 0) 
30               os.write(b, 0 ,i);
31         }
32         catch (Exception e)
33          {
34             e.printStackTrace();
35         }
36         finally
37          {
38             fis.close();
39             os.flush();
40             os.close();
41         }
42     }
43
44     public void doPost(HttpServletRequest request, HttpServletResponse response) 
45        throws ServletException, IOException
46      {
47          doGet(request,response);
48     }
49 }
