Description:
----------------

The dbstore_classpath has been set in the tibemsd.conf as follows:

dbstore_classpath       = C://tibco/components/eclipse/plugins/com.tibco.tpcl.org.hibernate_3.2.5.001/hibernate3.jar;C://tibco/components/eclipse/plugins/com.tibco.tpcl.org.com.mchange.c3p0_0.9.1.001/c3p0-0.9.1.jar;C:\tibco\ems\5.1\bin\antlr-2.7.6.jar;C:\tibco\ems\5.1\bin\asm-attrs.jar;C:\tibco\ems\5.1\bin\asm.jar;C:\tibco\ems\5.1\bin\cglib-2.1.3.jar;C:\tibco\ems\5.1\bin\commons-collections-2.1.1.jar;C:\tibco\ems\5.1\bin\commons-logging-1.0.4.jar;C:\tibco\ems\5.1\bin\dom4j-1.6.1.jar;ehcache-1.2.3.jar;jta.jar;C:\sqljdbc_2.0\enu\sqljdbc4.jar

All other configurations are fine. While starting the EMS server from the command line at C:\tibco\ems\x.x\bin with the same config file, the EMS server starts correctly. However, when the EMS server is configured as a Window service, it fails to start with the same config file.

Environment:
-----------------

1).  TIBCO Enterprise Message Service – 5.x+
2).  Microsoft Windows


Symptoms:
---------------

The following messages are seen in the EMS server log:

2010-05-16 14:35:18.479 java.lang.NoClassDefFoundError: javax/transaction/Synchronization :
:
2010-05-16 14:35:18.480 SEVERE ERROR: Unable to open store [$sys.failsafe]: [ ESTATUS = 230, ERRSTR = java.lang.NoClassDefFoundError: javax/transaction/Synchronization ]
2010-05-16 14:35:18.571 ERROR: Initialization failed: storage for '$sys.failsafe' not found.
2010-05-16 14:35:18.572 FATAL: Exception in startup, exiting.


Cause:
--------

As per the configuration, ehcache-1.2.3.jar and jta.jar are pointing at the current directory and are required to start EMS server using a database store. These two jar files are located at C:\tibco\ems\x.x\bin directory. When the EMS server is started from command line from C:\tibco\ems\x.x\bin, the EMS server finds them in the current directory and loads them. But while starting as a Windows service, the EMS server cannot find those files in the current directory as there is no absolute path for those two jar files.

Resolution:
--------------

Set the absolute PATH for these two jar files in the main config file of the EMS server.

TIBCO Enterprise Message Service (EMS) server starts correctly from the command line but when starting the server as a Windows NT service with the same config file, the server fails to start.
