Hello and help!
I need some serious hand holding to get me up and running with servlets.
I purchased two books on the subject: "Professional Java Server
Programming", published by Wrox; and "Java Examples in a Nutshell",
published by O'Reilly. And I really don't know what I'm doing.
I wish to run Servlets on a Windows 2000 machine. With instructions from
PJSP, I downloaded the servlet package from Sun. The file I downloaded
was "servlet-2_3-fcs-classfiles.zip", in the directory
http://java.sun.com/products/servlet/download.html. The files I got were
in three directories, javax/servlet/http. Then I attempted to compile the
following "Hello World" program they provided:
-----------------------
// Import Servlet Libraries
import javax.servlet.*;
import javax.servlet.http.*;
//Import java Libraries
import java.io.*;
public class HelloWorld extends HttpServlet
{
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("<HTML>");
out.println("<HEAD>");
. . . Finish generating html document with "Hello World" in
the body.
out.println("</HTML>");
out.close();
}
}
-----------------------
I could not get the compiler to recognize the javax class files, and this
problem persisted no matter where I placed the javax directory. I tried
placing it directly under the root and beneath my Java (c:\jdk1.3.1_01)
directories, to no avail.
Then I turned to my other book, JEIAN, and they recommended going to
Tomcat's website, http://jakarta.apache.org, and this time I downloaded
jakarta-tomcat-4.0.1.exe. This download has a richer set of files and
directories, downloaded to "C:\Program Files\Apache Tomcat 4.0", but
there's no help file (*.hlp) in the bunch.
Still I flounder. Questions: 1) Do either of the programs I downloaded
come with decent documentation for neophytes? 2) How do I get the java
compiler to recognize my javax files and successfully compile my program?
3) Which download is better for my situation: Sun or Tomcat? And the
second phase: 4) Where do I place the successfully compiled file to get my
browser to recognize it? 5) When I get beyond "Hello World", do I have to
worry about Explorer and Netscape treating the compiled files differently?
Thank you.
