NAME=Billy  POST  There is not a limitation in the length of the transmission character string.  It is possible to transmit only by <form> tag. Web application Client Web browser Display reading page URL address Internet Application server Request Response Link in a Web page Run application Features of Web application  Application server  It has the execution environment such as Web containers,  the connecting function to database: MySQL, SQL Server, etc.  transaction management function to couple two or more processing, and more.  Web container :  an execution environment to execute the server applications (CGI) : Servlet and JSP, ASP, PHP, etc.  example is ‘Tomcat’, etc. Directory structure of Web application (Tomcat) Web server ROOT directory HTML file, JSP file, image files, etc. WEB_INF web.xml classes lib  configuration file  class file  class file  The contents are not open to the client  can be directly accessed from the Web browser Collaboration between Servlet, JSP and JDBC Web browser Display reading page Application server Request Response Servlet JSP pages DBMS JDBC  Servlet : Java program that runs on Server side (Web container)  JSP : Embedding the Java program into the HTML files Using directly JDK  Edit program : Editor (NotePad)  Execution program : Dos Prompt : [...]... role and composition of IDE   IDE : integrated development environment Characteristics :    editor and compiler are integrated All processes from editing to execution can be done with one set of software Java IDE Exemples :    Eclipse Visual Studio (Microsoft) Sun ONE Studio (Sun) Characteristics of Eclipse       Eclipse is an IDE (free, open source) for Java application Extension of Functions...
