, WebLogic Server returns a proxy object that is encapsulated by the resource adapter and returned to the client. WebLogic server uses this proxy to provide functionality to help applications use the WebLogic Server's "Java EE Connector Architecture" implementation. These features include the (1) connection leak detection feature and (2) a connection request that delays XAResource enlistment when it is issu

these technologies are based on the request-answer model, which is not really a real time technology; each time they request and answer, they waste a certain amount of traffic in the same header information, and the development of complexity is also large. With the websocket of HTML5, real time communication of the web is realized, which makes the B/s mode have the real-time communication ability of C/s mode. The WebSocket workflow is this: The browser sends a request to the server to establis

.= "Reference variable is not necessarily stored in stack memory, eg,3 dimension array* Easy to confuse: When does a reference variable refer to its own province, and when does it refer to its referenced object in heap memory?does not call its method or property, refers to itself, and vice versa, refers to the object it references in heap memory6. Primitive type array: Each element is a value type (base type)Array of reference types: Each element is also a reference type, and you need to point t

First, IntroductionTomcat is the smallest Web server that implements the Java EE Standard and is a core project in the Apache Software Foundation's Jakarta Project, developed by Apache, Sun, and other companies and individuals. Because of advanced Tomcat technology, stable performance, and open source free, so deeply loved by Java enthusiasts and have been recogn

methods: Some places also called functions, in order to improve the reusability of the code, the content can be defined as a separate function, the embodiment of this function is the method in Java.Java inside method defines the format:modifier Returns a value type method name (parameter type form parameter 1, parameter type form parameter 1, ...) { Execute the statement;If you do not have a type that defines the return value, you do not have to return any content, otherwise:return return value;
