market, production, development of each part, and most of the development is an existing, mature program, the key point is not much, only need to solve the key problems.Don't make technology look so important, technology is not 100%, just a small part.What is the team's common goal? Not release technology, but do a good product and then sell products,

technology, which is no longer confined to a desktop system on a single machine, but rather targets a broader intranet, or even an international interconnection network. COM + and Multilayer architecture models (Windows DNA architecture, see the next section) and the Windows operating system provide a complete set of solutions for enterprise applications or Web applications."Problem".

, the waking thread must be the thread that waits the longest. However, in Java technology, this is not guaranteed.Note that notify () can be called regardless of whether the thread is waiting. If you call the Notify () method on an object, and there are no threads in the lock flag waiting pool for the object, then the Notify () call will have no effect.In Java, multithreading is a magical theme. It is "magical" because the running results of multi-th

I read a master's degree and climbed a circle in the academic circle. If in the academic circle, someone has proposed an idea, the theory, needs to go through the colleague to temper over and over, when you blow the good, the nonsense, then you basically in this line of fame is bad thoroughly.But in the work circle, why not have this atmosphere?Do not know the leadership of technology, loading force, take a big data, cloud computing come out to bluff

The review of Jsp/servlet technology is as follows 1. Requestdispatcher.forward () is on the server side, when using forward (), the Servlet engine passes HTTP requests from the current servlet or JSP to another servlet,jsp or normal HTML file, or your form commits to a.jsp, The forward () redirect to b.jsp is used in a.jsp, where all the information submitted by form is available in b.jsp and the paramete
