Spring TCP Socket client not receiving data from Mainframe

Question

I am trying to use this example to send and receive the data to and from a Mainframe machine that uses HEX data to communicate. So I have the following in my config

Answer 1

This is not a DEBUG log, only INFO; your log4j configuration must be wrong.

inside deserialize

This is simply the receiving thread waiting for data; it is stuck in your for loop waiting for the mainframe to close the connection - I suggest you add some debug inside the loop.

EDIT

Commons-logging is missing from your POM...

    commons-logging
    commons-logging
    1.2

or switch to log4j2

    org.apache.logging.log4j
    log4j-core
    2.7

and create a log4j2 config file.

Spring Framework 5 now uses its own implementation of commons-logging that does not support log4j 1.x.
