Example 1 with ApplicationContext

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

the class TomEEMyFacesContainerInitializer method isFacesServletPresent.

private boolean isFacesServletPresent(final ServletContext ctx) {
    if (ctx instanceof ApplicationContextFacade) {
        try {
            final ApplicationContext appCtx = (ApplicationContext) get(ApplicationContextFacade.class, ctx);
