Hi,
While trying to run Server program (StepByStepServer.java) with modified configurations from JCO3 distribution on unix platform , it failed with below exception.
The same program runs fine on Windows XP but not on Linux5(32 bit,x86) as well as Solaris10(64bit,sparc) . Am i doing something wrong here? How come it is working on windows but not on unix platform. Please provide suggestion on how to fix this.
Stack trace was same on both Linux and Solaris.
********************************************************Stack Trace*******************************************
Stack trace suggest it as Communication failure but i made sure this is not case with successful ping.

This is caused by either a) erroneous server settings, b) the backend system has been shutdown, c) network problems. Will try next startup in 1 seconds.

Did you make the required port entry in the /etc/services file? You will need to add the gateway service port there. Then try to run your program.
