TIBCO Spotfire Server may fail to start with the following error in both server.log and catalina log file when there are multiple versions of spring-web.jar files deployed in Spotfire. This error is specific to spring-web.jar but similar errors can be seen if you have duplicate jar files.

To resolve, check if there are any duplicate jar files placed in "<server installation dir>/tomcat/custom-ext" , "<server installation dir>/tomcat/lib" and "<server installation dir>/tomcat/webapps/spotfire/WEB-INF/lib" folders and delete accordingly. In this example, spring-web.jar was placed in both <server installation dir>/tomcat/custom-ext and <server installation dir>/tomcat/webapps/spotfire/WEB-INF/lib folders, where as it supposed to be deployed only in "<server installation dir>/tomcat/webapps/spotfire/WEB-INF/lib" folder

Please note that any custom JAR files you add to the server (e.g. additional database drivers or custom extensions) should in general be placed in "<server installation dir>/tomcat/custom-ext".

TIBCO Spotfire Server may fail to start with "More than one fragment with the name [spring_web] was found. This is not legal with relative ordering" exceptions logged in the catalina.log and server.log. This can be caused by duplicate jar files.
