PTC recommends deactivating the scanning of JAR files from Tomcat, for example to increase startup performance or to avoid some error messages in the log files. See PTC® article numbers CS434417 and CS344564.
For customers who follow this recommendation, it is important to activate the scan for the innoface-wc-client.jar library from IFConneX, as otherwise the interface will not function fully. To activate the JAR scan for this one library only, the following configuration must be defined for Tomcat:
<JarScanner>
<JarScanFilter defaultPluggabilityScan="false" pluggabilityScan="innoface-wc-client.jar"/>
</JarScanner>
