问题
I am trying to migrate application deployed on weblogic 12 to tomcat 9 and while doing so I am facing following exception
java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml!
content of my web.xml is as follows
<?xml version="1.0" encoding="UTF-8"?>

Note : Tomcat would not be able to understand weblogic.xml hence I have created context.xml file in META-INF folder of my application and content of context.xml is as follows
<Context path="/temp-service-v2"/>
Name of my war file is temp-service-v2.war
