java - Difference between getLocalPort() and getServerPort() in servlets -


मैं सर्वलेटों का अध्ययन कर रहा हूं, मैं getLocalPort () और < कोड> getServerPort () । getLocalPort () का अर्थ है सर्वर साइड केवल तभी getServerPort ()

धन्यवाद

एक साधारण सेटअप में (जहां आपका एप्लीकेशन सर्वर / सर्वलेट कंटेनर सीधे क्लाइंट के अनुरोध को स्वीकार करता है) दोनों तरीकों से एक ही मान वापस आ जाएगा।

जब सर्वलेट कंटेनर क्लाइंट अनुरोध को स्वीकार करता है कि वह अनुप्रयोग नहीं है (उदाहरण के लिए जब आप अनुरोध को स्वीकार करने के लिए एक अपाचे HTTP सर्वर का उपयोग करते हैं और अनुरोध को स्वीकार करने के लिए और एजीपी के द्वारा टॉमकेट इंस्टॉलेशन को अग्रेषित करने के लिए), तो बंदरगाह से जुड़े ग्राहक (शायद 80, जब डिफ़ॉल्ट पोर्ट का उपयोग किया जाता है) और वह पोर्ट वापस करेगा जो टोमकैट HTTP सर्वर से कनेक्शन को स्वीकार करने के लिए प्रयोग किया जाता है (संभवत: 800 9 या ऐसा कुछ)।

.net - C# List<T>.Find(x=>x.Rectangle.Contains(Point)) FAIL -

For my life, I can not understand why this code generates the following output ... I think there is a bug or something while using the list and lambda, if type one rectangle exposes the property and you use the included method of rectangle object ... and the clear statement proves true while Find list method fails .... Onway Code Public Gridskeyr Warldtokapadsb (Point location) {location = _Map.WorldToClient (location); Gridsquare gs = this.find (x => x.Rectangle.Contains (location)); GridSquare KP = G.Find (X => X. laxative canteen (location)); & Lt; GridSquare & gt; List = kp.FindAll (x => x.Rectangle.Contains (location)); U.dp (list.Count); Gridskare sub = KP.Fid (X => X. laxative canteen (location)); If (sub == faucet) {u.dp (place to look for "location"); U.dp ("The location found in the grid category" + GS toaster ()); U.dp ("Grid Square Bounds" + gs.Rectangle.ToString ()); U.dp ("location found in keypad" +...

c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -

Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title? I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on. The first thing to look at after the code is that I stand by: The sample uses the main.cpp: qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show (); Some name changes in my name. CPP qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml"))); I'm not sure that the difference in using QQmlApplicationEngine...
