Issue/Introduction

This article relates to using Gen Web client/EJB server applications under Liberty Application Server.
It describes the various exceptions/errors javax.naming.NameNotFoundException, javax.naming.NoInitialContextException, "Using an invalid or unsupported application server" that may occur if the correct syntax is not used in the commcfg.properties file that is assembled into the Gen Java runtimes file genrt.jar:

1. The ear file name is incorrect e.g. cstest1.ear is used instead of cstest1 and this commcfg.properties entry is used:
*=EJBRMI Y cstest1.ear

Error received when client calls server:
TIRM030E: Application failed - Updates have been backed out
TIRM031E: Failing procedure exit data follows:
TIRM032E: Last or current action block id = 0022020097
TIRM033E: Last or current action block name = CLT1
TIRM034E: Last or current database statement = 0
TIRM035E: Current statement being processed = 0000000003

Environment

Gen 8.6 Web generation client calling EJB/EJB Web Services using EJBRMI under Liberty Application Server,.

Resolution

The correct EJBRMI syntax should be followed per commcfg.properties file comments:

#        For Liberty, when client and server are assembled in the same EAR, the format is:
#           <TRANCODE>=EJBRMI Y {EARFileName}
#                             Y                     : Flag for connecting to Liberty
#                             EARFileName           : Name of the server ear File
