Example 1 with ApplicationContextFacade

use of org.apache.catalina.core.ApplicationContextFacade in project tomee by apache.

the class TomEEMyFacesContainerInitializer method isFacesServletPresent.

private boolean isFacesServletPresent(final ServletContext ctx) {
    if (ctx instanceof ApplicationContextFacade) {
        try {
