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.

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.

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".
