JSP access with reusable ponents, such as Servlet, JavaBean and Javabased Web applications. JSP also supports directly in the Web page embedded Java code. JSP can be used two ways to access documents: JSP documents sent by the browser request, the request sent to the Servlet. JSP technology uses Java programming language, XMLtype tags and scriptlets, to have a package deal with the logic of dynamic pages. Page tags and scriptlets can also exist in the server access to the resources of the application logic. JSP logic and Web page design and display isolated and support reusable ponentbased design, Webbased applications more quickly and easily developed. The Web server w hen meets visits the JSP homepage the request, first carries out segment, will then carry out the result code to return together with JSP in the document HTML for the customer. The insertion Java segment may operate the database, again the directional homepage and so on, realizes the function w hich the establishment dynamic homepage needs. JSP and Java Servlet are the same, is in the server end execution, usually returns to this client side is a HTML text, therefore client side, so long as has the browser to be able to glance over. The JSP page is posed of the HTML code and the inserting Java code. The server in the page by the client side was requested that later will carry on processing to these Java code, will then produce the HTML page will return gives the client side the browser. Java Servlet is the JSP technology base, moreover the largescale Web application procedure39。s development needs Java Servlet and the JSP coordination can plete. JSP had the Java te chnology simply easy to use, plete objectoriented, had the platform independency, and safe reliable, mainly faced Inter39。s dynamic content originally. Production content39。s form transmits the result by HTML the browser. This both are helpful in the author protects ow n code, and can guarantee a ny based on the HTML Web browser39。s method, and causes each kind of organization obtains balanced in their existing skill and in the optimized result development endeavor. uses marking The Web page development personnel will not be the familiar script language programmers. The JSP technology has sealed many functions, these functions are easy to use, marking to carry on the dynamic content production with JSP in the related XML to need. The standard JSP marking can visit and the instantiation JavaBeans module, the establishment or the retrieval module attribute, dow nloads Applet, as well as the execution difficulty with codes and the time consuming function with other methods. adapts the platform Nearly all platforms support Java, JSP+JavaBeans to be possible to pass unimpeded nearly under all platforms. Transplants from a platform to other platform, JSP and JavaBeans does not even need to translate, because the Java byte code is standard has nothing to do with the platform. database connection In Java connects the database the technology is the JDBC, Java procedure is connected through the JDBC driver and the database, operations and so on execution inquiry, extraction data. Sun Corporation has also developed JDBCODBC bridge, uses this technical Java procedure to be possible to visit has the ODBC driver database, at present the majority database systems have the ODBC driver, therefore the Java procedure can visit such as Oracle, Sybase, MS SQL Server and databases and so on MS Access. In addition, through the development marking storehouse, the JSP technology may further expand. The third party development personnel and other personnel may found their marking storehouse for the monly used function. This enables the Web pa ge development personnel to be able to use the familiar tool and to be similar to marking same carries out the specific function ponent to carry on the work. The JSP technology very easy conformity to many kinds of application architecture, to use the e xtant tool and the skill, and can expand to the support enterprise distributional application. 3 Eclipse function synopsis More and more Java development personnel already started the productivity which and the quality ine appreciates Eclipse JDT to pro vide. It was the Java editor provides grammar Gao Liang to demonstrate that the formatting, the fold, the content were auxiliary, code template and so on many functions. It grows unceasingly available restructuring and the code generation function set perm its you in a higher rank the operation code, and automated usual code intensity duty and easy wrong duty. Moreover, in develops the code and uses JDT to pile and to carry out the JUnit test builtin support carries on the unit testing after the code, may use Eclipse the firstclass Java debugger debugging w hen the movement meets any question. Besides JDT, Eclipse SDK the most popular downloading also contains Plugin Development Environment(PDE). PDE used the specific function to expand JDT to construct the Eclipse plugin unit based on the Eclipse application procedure basic cons
