API Developer Portal 3.5 includes Apache Tomcat as following:
|Non-CR to CR3||Apache Tomcat/6.0.39|
|CR4 or later||Apache Tomcat/8.5.14|
When upgrading to CR4 or later from the earlier version, you may find that some attribute names of <Resource> element are incorrect in Tomcat server.xml file.
File location: /opt/Deployments/lrs/server/conf/server.xml
Attribute name to be corrected:
|Original Name||Correct Name|
The "validateQuery" is an incorrect value even for Tomcat 6.0.39.
validationQuery is the correct attribute for Tomcat 6.0.39 and 8.5.
The presence of validateQuery in the server.xml of old Portal is a bug.
If you are using CR4 or earlier Portal 3.5 (or Portal 3.1) you also have to modify the validateQuery.
