2、ework for JAVAEE 1. JSP Profile  JSP (Java Server Pages) is initiated by Sun Microsystems, Inc., with many companies to participate in the establishment of a dynamic web page technical standards. JSP technology somewhat similar to ASP technology, it is in the traditional HTML web page document

3、(*.htm, *. html) to insert the Java programming paragraph (Scriptlet) and JSP tag (tag), thus JSP documents (*.jsp). Using JSP development of the Web application is cross-platform that can run on Linux, is also available for other operating systems.  JSP technology to use the Java programming l

4、anguage prepared by the category of XML tags and scriptlets, to produce dynamic pages package processing logic. Page also visit by tags and scriptlets exist in the services side of the resources of logic. JSP page logic and web page design and display separation, support reusable component-based des

5、ign, Web-based application development is rapid and easy. Web server in the face of visits JSP page request, the first implementation of the procedures of, and then together with the results of the implementation of JSP documents in HTML code with the return to the customer. Insert the Java programm

6、ing operation of the database can be re-oriented websites, in order to achieve the establishment of dynamic pages needed to function.JSP and Java Servlet, is in the implementation of the server, usually returned to the client is an HTML text, as long as the client browser will be able to visit. &nbs

7、p;JSP 1.0 specification of the final version is launched in September 1999, December has introduced 1.1 specifications. At present relatively new is JSP1.2 norms, JSP2.0 norms of the draft has also been introduced.  JSP pages from HTML code and Java code embedded in one of the components. The s

8、erver was in the pages of client requests after the Java code and then will generate the HTML pages to return to the client browser. Java Servlet JSP is the technical foundation and large-scale Web application development needs of Java Servlet and JSP support to complete. JSP with the Java technolog

9、y easy to use, fully object-oriented, and a platform-independent and securemainly for all the characteristics of the Internet. JSP technology strength: (1) time to prepare, run everywhere. At this point Java better than PHP, in addition to systems, the code not to  make any changes.(2) the mult

10、i-platform support. Basically on all platforms of any development environment, in any environment for deployment in any environment in the expansion. Compared ASP / PHP limitations are obvious. (3) a strong scalability. From only a small Jar documents can run Servlet / JSP, to the multiple servers c

11、lustering and load balancing, to multiple Application for transaction processing, information processing, a server to numerous servers, Java shows a tremendous Vitality. (4) diversification and powerful development tools support. This is similar to the ASP, Java already have many very good developme

12、nt tools, and many can be free, and many of them have been able to run on a variety of platforms under. JSP technology vulnerable： (1) and the same ASP, Java is the advantage of some of its fatal problem. It is precisely because in order to cross-platform functionality, in order to extreme stretchin

13、g capacity, greatly increasing the complexity of the product. (2) Java's speed is class to complete the permanent memory, so in some cases by the use of memory compared to the number of users is indeed a "minimum cost performance." On the other hand, it also needs disk space to store a

14、 series of. Java documents and. Class, as well as the corresponding versions of documents.  2. J2EE Development Framework Java2 Enterprise Edition middleware unified ideology played a significant role. For example, J2EE for distributed transaction management, directory services and messaging se

15、rvices provide a standard programming interface. J2EE-based -Java2Standard Edition (J2SE), successfully access for Java provides a standard relational database. But, as this article "J2EE programming of the lack of support", as mentioned, J2EEplatform does not provide a satisfactory applic

16、ation programming model. Sun and some of the major application server vendors wanted to use the development tools to reduce the complexity of J2EE development, but these tools are no other outstanding JAVA development tools, which have advanced refactoring tools, and. NET platform compared, J2EE too

17、l support appeared to be very inferior. Many J2EE development tools automatically generate the code for the same complex as the tools themselves. In many small-scale J2EE open source community developers chose another way of development - some can be difficult to reduce the development of J2EE development framework, the more popular such as: Struts, Hibernate, and Spring Framework, J2EE project types in many of today they play an important the role.
