Hi,
Not sure if anyone has used NIO connector in embedded tomcat 7 but I am
out of luck so far. It seems so simple but I could not get it work. I am
wondering if this is a bug in embedded version of tomcat because it works
fine on standalone version. If this turns out to be a bug in tomcat 7
embedded, then I may have to think about moving to Jetty but it would be
ideal if I can figure this out with tomcat 7 itself.
I am pasting the complete method that create Tomcat instance with NIO
connector and starts it. If I don't have NIO connector all rest requests
works perfectly. But with this NIO connector I can't connect to server. I
looked at the tomcat unit tests and they don't seem to be doing anything
special for NIO connector. Any help would be appreciated.
public void init() throws LifecycleException, IOException {
log.debug("Initializing Tomcat");
final File base = createBaseDirectory();
log.info("Using base folder: " + base.getAbsolutePath());
final Tomcat tomcat = new Tomcat();
tomcat.setPort(TOMCAT_PORT);
tomcat.setBaseDir(base.getAbsolutePath());
Context context = tomcat.addContext("/perfmon",
base.getAbsolutePath());
//handle rest requests
Wrapper cxfServlet = Tomcat.addServlet(context, "CXFServlet",
new
CXFServlet());
cxfServlet.addInitParameter("config-location",
"classpath:perfmon-rest-server.xml");
cxfServlet.setLoadOnStartup(1);
context.addServletMapping("/rest/*", "CXFServlet");
context.addApplicationListener(ContextLoaderListener.class.getName());
context.setLoader(new
WebappLoader(Thread.currentThread().getContextClassLoader()));
//atmosphere websocket support
Wrapper atmosphereServlet = Tomcat.addServlet(context,
"AtmosphereServlet", new TomcatAtmosphereServlet());
atmosphereServlet
.addInitParameter("org.atmosphere.cpr.packages",
"com.kiva.perfmon.prototype.pubsub.websocket");
atmosphereServlet.setLoadOnStartup(0);
context.addServletMapping("/pubsub/*", "AtmosphereServlet");
context.addParameter("contextConfigLocation",
"classpath:perfmon-context.xml");
// add nio connector for websocket support
Connector nioConnector = new
Connector(Http11NioProtocol.class.getName());
nioConnector.setPort(TOMCAT_PORT);
nioConnector.setProperty("address",
InetAddress.getByName("localhost").getHostAddress());
tomcat.setConnector(nioConnector);
tomcat.start();
tomcat.getServer().await();
}
Thanks in advance.
