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

CR102119Summary: A serializable custom object wraps Ejbobject (a reference to an EJB). The custom object is stored in an HTTP session. This design causes classcastexception when a session is copied.Workaround: This issue will be completely resolved in a later version of WebLogic Server. The current w

of Selenium 2004 at ThoughtWorks, a company called Jason Huggins to reduce manual testing, he wrote a set of JavaScript libraries that can interact with pages and repeat tests on different browsers. This set of libraries later became selenium Core. Provides a solid core foundation for the Selenium Remote control (RC) and selenium IDE Selenium's role is epoch-making because it allows you to control browsers in multiple languages. The browser's security
