The error message in the STAX JVM Log says it can't find class 
com/ibm/staf/service/STAFServiceHelper.  This class is provided in the 
JSTAF.jar file so my guess is that you don't have the JSTAF.jar file in 
your CLASSPATH when starting STAFProc.  Check your CLASSPATH and make sure 
that it contains the JSTAF.jar file (located in the STAF lib directory, 
e.g. /usr/local/staf/lib/JSTAF.jar).

See the STAF Installation Guide at 
http://staf.sourceforge.net/current/STAFInstall.pdf, section "7. 
Environment Variable Settings" for more information on the required STAF 
environment variables.  Note that if you used a STAF InstallAnywhere 
installer and used the default setting to have the install update the 
environment variables on your system for STAF, then the JSTAF.jar file 
would have been set for your by the install.

Or, if you use startSTAFProc.sh (in /usr/local/staf) to start STAFProc, 
then it runs STAFEnv.sh before starting STAFProc and it sets the 
environment variables for STAF, including adding the JSTAF.jar file to the 
CLASSPATH).

Subject:        [staf-users] STAF fails to start when STAX is added to the 
configuration file



Hi,

I have used the 64-bit installer to install STAF:
-bash-4.1# cat /usr/local/staf/install.properties
version=3.4.9
platform=linux-amd64
architecture=64-bit
installer=IA
file=staf.bin
osname=Linux
osversion=*
osarch=amd64


I also have 64-bit java installed:
bash-4.1# java -version
java version "1.6.0_23"
Java(TM) SE Runtime Environment (build 1.6.0_23-b05)
Java HotSpot(TM) 64-Bit Server VM (build 19.0-b09, mixed mode)

When  I add the following line to STAF.cfg, STAF fails to start:
SERVICE STAX LIBRARY JSTAF EXECUTE /data/STAF/src/stax/STAX.jar OPTION 
J2=-Xmx512m
SERVICE EVENT LIBRARY JSTAF EXECUTE /data/STAF/src/stax/STAFEvent.jar
SET MAXQUEUESIZE 10000

I get the following error message:
Error on Service definition line:
SERVICE STAX LIBRARY JSTAF EXECUTE /data/STAF/src/stax/STAX.jar OPTION 
J2=-Xmx512m
Error code: 27
Reason    : Error constructing service, JSTAF, Result: Unable to connect 
to JVM
Error in configuration file: /usr/local/staf/bin/STAF.cfg


JVMLog shows the following:
*** 20120702-12:58:38 - Start of Log for JVMName: STAFJVM1
*** JVM Executable: java
*** JVM Options   : -Xmx512m

Could not find the main class: com.ibm.staf.service.STAFServiceHelper.  
Program will exit.

This happens on a system running Rhel6.2. It seems to work on another 
system running Rhel 5.6.

Any ideas on what is preventing STAF from starting ?

Thanks
Anna
