Issue/Introduction

CA Gen 8.6 Web client and EJB successfully deployed to the same WildFly 10.1 instance in a single ear file.
When the Web client calls the EJB server it fails with error:

TIRM158E: A communication error was encountered on the client 
[Function: EJBRMIDynamicCoopFlow.processException.EJBRMI.Exception]java.lang.IllegalStateException: 
EJBCLIENT000025: No EJB receiver available for handling [appName:, ModuleName: xxxxxxxx, distinctName:]... 

Environment

CA Gen 8.6. WildFly10.1 support PTFs installed

Cause

The commcfg.properties file has been included from the CA Gen installation directory (%GEN86%\Gen, default: C:\Program Files (x86)\CA\Gen86\Gen) using Build Tool Assemble step "Include optional runtime property files". That file contains an incorrect trancode mapping for calling the Gen EJB server manager.

Resolution

To call a local EJB under same WildFly instance this syntax should be used in the commcfg.properties file:
<server trancode>=EJBRMI W <ear_filename>
<server trancode> = Server  Manager trancode or alternatively a wildcard '*' e.g. *=EJBRMI W <ear_filename>
<ear_filename> =  name of the ear file deployed to WildFly (NOTE: the .ear extension should not be included)
