The Research And Development Of Network Testing System Based On JAVA

At present, The test-on-the-web at many tests such as the training test,certificate test, subject test and so on, will be conducted on the net. The test on theweb will be used widely, and its superiority will be displayed. The test-on-the-websystem developed by Jave has become a popular international way of test andcertification for its fairness, safety, accuracy, flexibility, randomization, timelinessand convenience.But nowadays some imperfections such as the unsafety, the web factor andhigh-technology cheating and so on, still exist in many test-on-the-web systems. Theprimary dispirits include the unstandardization, the weakness of expand and contract,the service difficulties. At the same time these systems can't share the openresources.According to the above situation, the system strives to remedy the defects, andThe system chooses the present most popular way of web applicated developmentJ2SE+XML the advanced technology, as the development platform in order to satisfythe application, mutual conduct and development contents such demands.J2SE+XML is sure to be the most popular way of web application development withits efficiency, safety and easy handing.The system is made up of two subsystems for test application and testmanagement, also including two clients, one for students to have a test, another forteacher to complete corresponding management. Fully considering the safety andextensibility of the test surrounding, the system use three-layers structure to designand develop, at the same time, to offer the application service as the middle platformcompleting the data conduct.
