Informix 4gl Web service

I am exploring new Informix 4gl web serrvice feature. The new version of Inforix 4gl is installed and all environment variable are set as required for AXIS2C webs erver. The examples web services - $INFORMIXDIR/$AXIS2C/services/math is working properly when I run the sampel client program - $INFORMIXDIR/$AXIS2C/bin/samples/math locallly on the box where Informix and Axis are installed. When I tried to test the same webservice via Eclipse web service explorer and provide the URL - http://servername:9090/axis/services/math?wsdl, it shows various methods (Add, Sub etc) and request for the integer parameters. But when I supplied the values and try to get result, it comes back with unknown error. The log files are not showing any errors. Similarly, as per Axis/2C manual, I should be able to see default web page with http://servername:9090/axis/. That is also not hapeening. Am I missing something or what should I check to ensure that everything is setr properly. Thanks
