On Connection Test, I get the error - ICM_HTTP_CONNECTION_FAILED
On running the trace in SMICM, I get the following:

[Thr  5] *** ERROR => IcmJ2EEScheduleFunc: Connection to srpidev.srhouse.com:8000 failed - please check host configuration (-8)
I get the foll on running the report: SPROX_CHECK_HTTP_COMMUNICATION
HTTP communication contains errors (see long text for diagnosis)
Message no. SPRX086

Hello Michal,
Thanks for your response.
Part of this problem has been solved right now...the http port on the R/3 server is 8002 and not 8000!!
Changing the port solved my problem from XI to R/3.
But the R/3 to XI error persists with the same behaviour. I have checked with BASIS, no firewall exists in between.
I have used the ip add while creating the http conn....do I have to change this elsewhere?
