Symptoms:
The class path is incorrect and the log4j jars has a wrong reference with other TIBCO products (BW and Hawk) or has different jar files loaded in a different order.
Cause:
Try starting the BE engine in command line mode with debug enabled.The '--debug' added to the command line executing is to see what classes are being loaded.
Example:
cd $BE_HOME\examples\standard\FraudDetection
$BE_HOME\bin\be-engine --propFile $BE_HOME\bin\be-engine.tra --debug -u default -c FraudDetection\fd.cdd fd.ear >FDEngineDebug.log
Resolution
Make the correct reference of log4j jars in the BE engine TRA file.
Add the property “%PSP%%BE_HOME%/lib/ext/tpcl/apache%PSP%” to front of tibco.env.STD_EXT_CP ( TIBCO standard classpath) to reference the correct log4j jars.
tibco.env.STD_EXT_CP =%PSP%%BE_HOME%/lib/ext/tpcl/apache%PSP% (followed by other properties)
tibco.env.STD_EXT_CP =%PSP%%BE_HOME%/lib/ext/tpcl/apache%PSP% (followed by other properties)
