Examples with ServletException javax.servlet.ServletException used on opensource projects

Example 1 with ServletException

use of javax.servlet.ServletException in project jetty.project by eclipse.

the class WebSocketCdiInitializer method onStartup.

@Override
public void onStartup(Set<Class<?>> c, ServletContext context) throws ServletException {
    ContextHandler handler = ContextHandler.getContextHandler(context);
    if (handler == null) {
        throw new ServletException("Not running on Jetty, WebSocket+CDI support unavailable");
    }
    if (!(handler instanceof ServletContextHandler)) {
        throw new ServletException("Not running in Jetty ServletContextHandler, WebSocket+CDI support unavailable");
    }
    ServletContextHandler jettyContext = (ServletContextHandler) handler;
    try (ThreadClassLoaderScope scope = new ThreadClassLoaderScope(context.getClassLoader())) {

    }
}
