Research On Web Application Based On J2EE And Struts Mode

Along with the development of Internet, the field of computer has changedincredibly. We can share the information in all parts of the world , render servicefor the customer, even carry on the electronic commercial activity. At thecontinual renovations of technology, we need faster, lighter, strongger going onapplication online that announce through Web. SUN corporation,for offering servers side solution with good expand andhigh transplantation, Embody nowadays Web application in using prevailing thestandard technologies of separately dealing with content show, business logic anddata source fully, has developed a kind of new technology which is calledSERVLET. The SERVLET, with high-efficient and platform-independent,applying an intermediate level of Object Oriented and well expand, Can visit APIfunction and EJB of enterprise edition JAVA, like JNDI and JDBC.On the basisof this, a series of new technologies such as Struts,etc. have appeared. This thesis,emphased the combination of J2EE and based on Struts of MVC,has introduced the idea of MVC pattern and the Tomcat Web server's loadbalancing .We realized the " address book" system with this method . At first, project background introduced the development trends of Webapplication and development study, and the subject meanings of reality combinedproject.Secondly project relevant background introduced the N-layer Architecturein software development, The software developer has put forward the concepts of 3-layers of structure in recent years. Whole to use and finish dividing into three a piece of thelogic ones of separations, each have one a suit of definition kind interfaces. The first layershows that layer is a figure interface that is represented to the user under general situation;The intermediate level is formed from logic of using, the third layer include and use thenecessary data. the general situation of the MVC pattern, which were comparedand analyzed. Then the author probed into J2EE and Web development approach.J2EE is the system structure of complicated problem that a kind of development,arrangement of making use of 2 platforms of Java to simplify a grade of application solution 53吉林大学硕士学位论文of a great deal of enterprises are correlated with management, Have offered calculationmodel and running environment of grade to an enterprise to use for developping anddisposing the application of the multilevel system. It calculates various kinds of essentialservices of environment through offering the enterprise, Make the multilevel applicationdisposing on J2EE's platform can realize high usability, security and can expand the sex anddependability ;based on Struts of MVC structure deeply.LDAP, based on the projectrequirement related to this thesis, extremely extensive that LDAP uses abroad atpresent whereas in developing stage at home, is exactly used in the administrativesystem of Beijing University. In recent years, with the LDAP( Directory Access Protocolof Light, visits agreements in lightweight catalogue) rise of technology and constantexpansion of the application, Catalogue serve technology become new-type technologiesesrealize information store, manage and first-selected scheme that inquire about, Especially innetwork resources look for, The user visits and controls the respects, such as inquiry,new-type network service, the in common use data bases , Need and use catalogue servetechnology come and realize each in common use perfecting, use simple and system that maybe expanded. In the following the edition controlled software CVS used in thecourse of software development is introduced summary.J2EE and the MVC'spattern Web's technique finally introducing to based on is living the realization in" notebook of address " system , and consists of the systematic needs analysis ,design of system together with realization , and unite the system realization , andintroduced the conformity of Tomcat+...
