关于ice:fileinput的问题

问题已经解决，但仍不知道原因。通过设置绝对路径，使得上传文件得以实现：

 <context-param>
         <param-name>com.icesoft.faces.uploadDirectory</param-name>
         <param-value>C:\Uploads</param-value>
     </context-param>
     <context-param>
         <param-name>com.icesoft.faces.uploadDirectoryAbsolute</param-name>
         <param-value>true</param-value>
     </context-param> 
 

以及：

 public void essaiDeplacer(ActionEvent event){
 		String id = ((HttpSession)FacesContext.getCurrentInstance().getExternalContext().getSession(false)).getId();
 		
 		InputFile inputFile =(InputFile) event.getSource();
 	      //file has been saved
 	       if (inputFile.getStatus() == InputFile.SAVED) {
 	            String fileName = inputFile.getFileInfo().getFileName();
 	            System.err.println("filename = "+fileName);
 	            File source = new File("c:\\Uploads\\"+id+"\\"+fileName);
 	    		File destination = new File("c:\\Uploads\\"+fileName);
 	    		source.renameTo(destination);
 	       }
 	}
