I have used jboss-4.0.5.GA version before and now I need to upgrade it to wildfly latest version. In old version I have used jbossweb-tomcat55.sar to deploy war files. In wildfly12 it has to do with undertow subsystem in standalone.xml file. But I wasn't able to do the configurations correctly. Is there any way to keep jbossweb-tomcat55.sar without undertow subsystem configuration?
