The following error may occur when starting the adapter:

==============================================

Product: TIBCO ActiveMatrix BusinessWorks Plug-in for Database Version: 7.3.x OS: All Supported Operating Systems

The above issue occurs if "slf4j-log4j12-1.7.31.jar" is loaded before slf4j-simple-1.7.31.jar or log4j-slf4j-impl-2.17.1.jar.
When the adapter starts, it loads the log4j jar files from TPCL_HOME/lib. The OS determines the order in which the jar files are loaded. Sometimes, the "slf4j-log4j12-1.7.31.jar" is loaded first, and this causes the above problem.

To resolve this problem, add "%TPCL_HOME%/lib/slf4j-simple-1.7.31.jar" to the beginning of tibco.class.path.extended in the adapter tra file to ensure that the adapter loads slf4j-simple-1.7.31.jar first.

"java.lang.NoClassDefFoundError: org/apache/log4j/Level" occurs when starting the adapter
