Issue/Introduction

Description:

When attempting to connect to EJBs deployed on Websphere 7 from a GUI C client via the CFB Converter service the following format error is returned:

TEST_SERVER TSRV

Solution:

In WAS 7 there is an additional step that should be performed in order for the connection from the CFB converter service to work.

Once the server EJB ear file has been deployed in WAS you must then run a batch job which will create the stub files required for communication with it. To do this in a command window on the WAS system navigate to where the EJB has been deployed e.g.

C:\Program Files\IBM\WebSphere\AppServer\profiles\AppSrv01\installedApps\server1Node01Cell\CFPMODEL.ear
14/06/2011 10:04 516,900 genrt.80.jar
17/06/2011 13:44 <DIR> META-INF
17/06/2011 13:43 12,876 TESTSRV.jar
2 File(s) 529,776 bytes
3 Dir(s) 52,904,849,408 bytes free

You will see the EJB jar file TESTSRV.jar in the above directory listing.

We need to run the WAS bat job createEJBstubs against this file as follows:

..\..\..\bin\createejbstubs TESTSRV.jar -newfile

Processing the TESTSRV.jar input file.
Command Successful

This will create a new jar file

17/06/2011 13:54 14,425 TESTSRV_withStubs.jar

This file needs to be placed on the CLASSPATH for the CFB server. So if the CFB server is running on a different system it is necessary to copy the file to the CFB location and then set the CLASSPATH in the CFB bat file. E.g.

SET CP=.
SET CP=%CP%;Z:\WebSphere_CFBServer8\TESTSERV_dpy.jar
SET CP=%CP%;Z:\WebSphere_CFBServer8\TESTSRV_withStubs.jar
SET CP=%CP%;Z:\WebSphere_CFBServer8\genrt.80.jar;Z:\WebSphere_CFBServer8\jcfb80.jar
SET CP=%CP%;Z:\WebSphere_CFBServer8\com.ibm.ws.ejb.thinclient_7.0.0.jar;Z:\WebSphere_CFBServer8\com.ibm.ws.orb_7.0.0.jar
java -cp "%CP%" -Djava.security.policy=CFBServer.policy com.ca.gen80.jcfbserv.server.CFBServer

This will then allow connection to the EJB via the CFB converter service.
