APAR status

• Closed as program error.

Error description

• Issue sending data in GZIP format via a Java Stream to a
  servlet deployed in WebSphere. In WebSphere Application Server
  v6.0.2 instance a read of the input stream triggers an
  EOFException. This functionality works in WebSphere Application
  Server v5.1, but does not work in 6.0 or 6.1.
  
  SystemOut.log shows the following error:
  ---------------------------------------
  [9/28/06 9:35:13:847 PDT] 00000019 WCCByteBuffer E Failed to get
  next body buffer
  
  Note: EOFException may or may not be logged.

Problem summary

• ****************************************************************
  * USERS AFFECTED: WebSphere Application Server version 6       *
  *                 users of the HTTP channel using both         *
  *                 compression and chunked encoding.            *
  ****************************************************************
  * PROBLEM DESCRIPTION: The HTTP channel is receiving a body    *
  *                      decompression error on the second chunk *
  *                      read off the network.                   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The proper HTTP handling of both body compression and chunked
  encoding is that Content-Encoding (compression) is applied to
  the entire body and then Transfer-Encoding is applied as it is
  sent. This means the server side that receives that body must
  read the entire chunked body first, then decompress. The HTTP
  channel was attempting to decompress each individual chunk,
  thus it received the decompression error on the second chunk.
  

Problem conclusion

• The HTTP channel has been updated to apply the encodings in the
  proper order when reading in such a body, as well as now
  applying the encodings correctly with outgoing messages.
  
  The fix for this APAR is currently targeted for inclusion
  in fixpacks 6.0.2.17 and 6.1.0.5.
