Tomcat requires a default Web application in /webapps/ROOT. In PAS for OpenEdge, the default root application is a deployment of oeabl.war. To suit the requirements of your particular development or deployment environment, you can replace ROOT with your own Web application and redeploy oeabl.war. For example, you can:
1. Delete the existing root application in a PAS for OpenEdge instance's /webapps folder.
2. Rename your Web application as ROOT.war.
3. Deploy your ROOT.war to the PAS instance.
4. Redeploy the default oeabl.war application, which can be found in $CATALINA_HOME/extras, under a folder other than ROOT.
