How to configure an EAP6 ejb-client to fail fast if the network connection fail

Solution Verified - Updated -

Issue

  • My ejb client is blocked for a long time if the network connection failed, how can I avoid this?
  • I use a UNIX command to simulate a network failure and my clients stuck, how can I configure a faster failure?
iptables -P INPUT DROP ; iptables -P FORWARD DROP ; iptables -P OUTPUT DROP
  • The ejb client hang for longer and the configuration of org.xnio.Options.READ_TIMEOUT and org.xnio.Options.WRITE_TIMEOUT does not help, which property need to be configured?
  • To test the client failover behaviour a network administrator shuts down the switch port of one machine.
    Afterwards the client tries to call a remote function which fails with an error after waiting for the configured invocation-timeout.
