auditing in java application

In the design of today's multi-tier Web applications, we can use both Java applets and servlet. Applets provide a convenient mechanism for creating powerful dynamic interfaces that provide an efficient means of processing requests from Web servers or other application servers. The Sun's application model describes the best specification for developing enterprise

As we all know, Java Web Start (JWS) supports distributing applications in a web-based manner. So why do you want to distribute the Java Web Start (JWS) application over the CD-ROM? There are many reasons for this. For larger applications, a full installation can be a pet-heavy download task, even with high-speed bandwidth. Second, not all desktop systems are onl

1. Using a thread poolWhen an application needs to handle multiple tasks, such as a Web server processing the requests it receives, you can use the thread pool. By reusing existing threads rather than creating new ones, you can apportion the huge overhead of thread creation and destruction as you process multiple requests. Another advantage is that when a request arrives, the worker thread usually already exists, so it will not delay the execution of

And Parrot has both of these capabilities, so we have both flyable and talkabl

account number, update cycle, and so on. Next, create the Listserver instance, and finally go to the infinite loop "read the new message and forward it to the subscriber/wait until the next check time arrives". The core functions of listserver (that is, reading and forwarding all new messages) are implemented in the process () procedure, and the main procedures are: Gets the Javax.mail.Session instance and then obtains the Javax.mail.Store instance. Use the Javax.mail.Store instance to get the

A regular expression is a formula that uses a pattern to match a type of string, and the regular expression consists of some ordinary characters and some metacharacters (metacharacters). Ordinary characters include uppercase and lowercase letters and numbers, while metacharacters have special meanings, whether they are. NET platform or Java platform, the meaning of the expression is the same, the following we mainly analyze the
