摘要：本文章主要是以tomcat jasper 2编译jsp档案为servlet的java源档案。就像JBuilder产生Servlet的功能，有助于jsp开发者debug。
标签：Java Eclipse Tomcat Jasper

产生Servlet源档案：
右键点选build_servlet.xml -> Run As -> Ant Build
然后Refresh Jasper2Sample Project
就会显示output_servlet -> org.apache.jsp.index_jsp.java

內容如下所示：

index_jsp.java

package org.apache.jsp;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
public final class index_jsp extends org.apache.jasper.runtime.HttpJspBase
implements org.apache.jasper.runtime.JspSourceDependent {
private static java.util.List _jspx_dependants;
public Object getDependants() {
return _jspx_dependants;
}
public void _jspService(HttpServletRequest request, HttpServletResponse response)
throws java.io.IOException, ServletException {
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;
PageContext _jspx_page_context = null;
try {
_jspxFactory = JspFactory.getDefaultFactory();
response.setContentType("text/html; charset=BIG5");
pageContext = _jspxFactory.getPageContext(this, request, response,
null, true, 8192, true);
_jspx_page_context = pageContext;
application = pageContext.getServletContext();
config = pageContext.getServletConfig();
session = pageContext.getSession();
out = pageContext.getOut();
_jspx_out = out;
out.write("\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" 
content=\"text/html; 
charset=BIG5\">\n<title>Jasper2 Sample</title>\n</head>\n<body>\n");
out.print("Hello Joeyta" );
out.write("\n</body>\n</html>");
} catch (Throwable t) {
if (!(t instanceof SkipPageException)){
out = _jspx_out;
if (out != null && out.getBufferSize() != 0)
out.clearBuffer();
if (_jspx_page_context != null) _jspx_page_context.handlePageException(t);
}
} finally {
if (_jspxFactory != null) _jspxFactory.releasePageContext(_jspx_page_context);
}
}
}
