當有訪問時 public void event(CometEvent event) throws IOException, ServletException 這個方法為什么沒執(zhí)行

public void event(CometEvent event) throws IOException, ServletException {

HttpServletRequest request = event.getHttpServletRequest();

HttpServletResponse response = event.getHttpServletResponse();

// 昵稱

String name = "wo";

System.out.println("+++++++++++23");

System.out.println(response);

if (event.getEventType() == CometEvent.EventType.BEGIN) {

// Http連接空閑超時

event.setTimeout(Integer.MAX_VALUE);

log("Begin for session: " + request.getSession(true).getId());

// 創(chuàng)建Comet Iframe

PrintWriter writer = response.getWriter();

writer

.println(""-//w3c//dtd html 4.0 transitional//en\">");

writer

.println("

");

writer.println("

writer.println("var comet = window.parent.comet;");

writer.println("");

writer.flush();

// for chrome

if (request.getHeader("User-Agent").contains("KHTML")) {

for (int i = 0; i < 100; i++) {

writer.print("");

}

writer.flush();

}

writer.flush();

synchronized (connections) {

connections.put(name, response);

}

} else if (event.getEventType() == CometEvent.EventType.ERROR) {

log("Error for session: " + request.getSession(true).getId());

synchronized (connections) {

connections.remove(name);

}

event.close();

} else if (event.getEventType() == CometEvent.EventType.END) {

} else if (event.getEventType() == CometEvent.EventType.READ) {

InputStream is = request.getInputStream();

byte[] buf = new byte[512];

do {

int n = is.read(buf); // can throw an IOException

if (n > 0) {

log("Read " + n + " bytes: " + new String(buf, 0, n)

+ " for session: "

+ request.getSession(true).getId());

} else if (n < 0) {

return;

}

} while (is.available() > 0);

}

}

tomcat 配置都配好了。

web.xml也

CServlet

/CServlet

grails
