public synchronized void reset() throws IOException { throw new IOException("mark/reset not supported"); } 1. 2. 3. 综上所述,在request.getinputstream读取一次后position到了文件末尾,第二次就读取不到数据,由于无法reset(),所以,request.getinputstream只能读取一次。 总结: 这个问题最根本还是对java IO...
EVALUATION I reclassified this as a JAF doc RFE, since it's not a bug in JavaMail. The DataSource docs should make it clear that getInputStream should produce a new InputStream every time it's called. ###@###.### 2002-02-23 This is clearly documented in the 1.0.1 docs. 23-02...

they support it. These parsers must be able to mark the stream, read enough data to determine whether they support the stream, and reset the stream's read pointer to its original position. If the input stream does not support these operation, this method may fail with an IOException. ===...
