      Hi ,

       

       

      I am working on migration project from Spring to SpringBoot and also we are changing Web app server to Redhat Enterprise App server . Currently I am trying to run the project after doing all changes on my machine where EAP has been installed .

       

      I tried to find and remove the duplicate declaration in pom.xml , removed all default dependancy of Tomcat from pom file but still I am facing the same issue . Please note that SpringBootServletInitializer has been extended in main class and configure method has been overriden , not sure if this is relevant or not .

       

      Following is an error when I deploy to RedHat EAP 7.2.0.ga (WildFly Core 6.0.11.Final-redhat-00001)

      I am not able to deploy the project in JBoss EAP 7.2.0.GA (WildFly Core 6.0.11.Final-redhat-00001) due to mentioned exception.
