Logging
You can use the following log4j flags to enable the logging in the Method Server.
log4j.logger.wt.ixb.publicforapps.extendedmapping =DEBUG or TRACE
log4j.logger.wt.ixb.publicforapps.extendedmapping =DEBUG or TRACE
The DEBUG level would identify the exact mapping rule that has come into effect while the TRACE level would provide you additional details on what different candidate mapping rules were evaluated.
