從http客戶端獲取404

Question

這裏我使用HTTP-CLIENT來調用servlet，但是如果我只點擊「http：//：8080/RemediPRMS/WritePingData」這個鏈接，它會給我響應代碼200，但是如果我運行它小程序它給了我404

Deployment descriptor mapping is : 
    <servlet> 
     <servlet-name>WritePingData</servlet-name> 
     <servlet-class>com.clientToServer.FileUploader.WritePingData</servlet-class> 
     </servlet> 
     <servlet-mapping> 
     <servlet-name>WritePingData</servlet-name> 
     <url-pattern>/WritePingData</url-pattern> 
     </servlet-mapping> 

    try{ 
       System.out.println("folder.listFiles().length"+folder.listFiles().length); 
       if(folder.listFiles().length > 0){ 
        System.out.println("inside if file found[][][[[][][][][][]["); 
        String remediEndpoint = "http://<endpoint>:8080/RemediPRMS/WritePingData"; 
        FileInputStream fis = null; 
        System.out.println("above for loop"); 
        File arr[] =folder.listFiles();//file array 
        System.out.println("array pass"); 

         PostMethod post = null; 
         System.out.println("just above for loop"); 
         for(int i=0;i<arr.length;i++){ 
          try{ 
           System.out.println("inside for loop"); 
           File targetFile = new File(path+"\\"+arr[i].getName()); 
           fis = new FileInputStream(targetFile); 
           post = new PostMethod(remediEndpoint); 
           post.setRequestEntity(new InputStreamRequestEntity(fis, targetFile.length())); 
           post.setRequestHeader("Content-type","text/plain; UTF-8"); 
           HttpClient httpclient = new HttpClient(); 
           httpclient.setConnectionTimeout(10000); 
           int status = httpclient.executeMethod(post); 
           fis.close(); 
           //boolean deletestatus= targetFile.delete(); 
           System.out.println("status from server : "+status); 
          }catch(Exception e){ 
           LOGGER.info("Exception in file upload (http client): "+e); 
          } 
         } 
         post.releaseConnection(); 
        }else{ 
         LOGGER.info("THERE IS NO MORE FILE TO UPLOAD "); 
        } 
       }catch(Exception e){ 
        LOGGER.info("No directory inside LogData: "+e); 
       }

您需要您所輸入的網址

例如部分主機名

http://myserver:8080/RemediPRMS/WritePingData 

或者假設你是，這仍然是沙箱不能

他們無法從任何第三方服務器（比它的起源服務器以外的任何服務器）連接到或檢索資源的applet。
