[xmlblaster] Socket connection: warning after disconnect

[Michael Justin <michael.justin at freenet.de>]

Dear all

I have managed to replace the xml-rpc based protocol layer by a sockt 
protocol implementation, however the disconnect give a warning and I am 
not sure if this is a serious problem.

It looks like xmlBlaster tries to read from the socket after the client 
has sent the disconnect command. The protol entry says "Error parsing 
TCP data from '/192.168.178.22:1076', check
if client and server have identical compression or SSL settings: 
java.net.Socket
Exception: Software caused connection abort: recv failed".

I have found this information about the disconnect: "The server sends 
the response (ACK) immediately from the SOCKET layer. It can't send it 
later because the socket is shutdown during server side disconnect." - 
so do I understand correctly that the client should handle disconnect in 
a different way? Currently it waits for an asynchronous response.

Here is the full log:
