Developed a program with JSP for some time, but it feels not enough to master the JSP. Now analyze the * _jsp.java file after compilation of * .jsp.java files. First write a simple my.jsp file as follows: <% @ Page ContentType = "text / html; charset = GB2312" Language = "Java" IMPORT = "java.sql. *" ErrorPage = ""%> "HTTML>
baiming </ title> </ head></p>
<p><Body> Hello </ body> </ html> ******************************************************* ************************************************************************************************************************* Run Tomcat, enter http: // localhost: 8080 / my.jsp in the address bar, you generate a MY_Jsp.java file under Tomcat root of directory / Work / Catalina / localhost / _ / org / Apache / JSP. Let's take a look at this file: package org.apache.jsp;</p>
<p>Import javax.servlet. *; import javax.servlet.http. *; import javax.servlet.jsp. *; import java.sql. *;</p>
<p>Public final class my_jsp extends org.apache.jasper.Runtime.httpjspBase imports org.apache.jasper.runtime.jspsourceDependent {</p>
<p>Private static java.util.vector _jspx_dependants;</p>
<p>Public java.util.list getDependants () {return_jspx_dependants;</p>
<p>Public void _jspservice (httpservletRequest Request, httpservletResponse response) throws java.io ioException, servletexception {</p>
<p>JspFactory _jspxFactory = null; PageContext pageContext = null; HttpSession session = null; ServletContext application = null; ServletConfig config = null; JspWriter out = null; Object page = this; JspWriter _jspx_out = null;</p></div><div class="text-center mt-3 text-grey">
