just tried it , you can delete the file.
I need is to generate reports with jfreeChart picture, and then export to Excel , and there I generate a picture with each stream up into Excel , Excel finally available for download with a stream form .
need wound tomcat / temp folder generated files can do:

      String filePath = D:/tomcat/temp/
      File[] tempFiles = tempFileDir.listFiles();
      File tempFileDir = new File(filePath);
      for (int i = 0; i < tempFiles.length; i++){
         //我生成的图片是*.png格式的
         if(tempFiles[i].getName().indexOf(".png") > 0){
             tempFiles[i].delete();
          }
      }
