Help compiling BookStore SERVLETS tutorial classes

I am new to Java. Please be patient with my errors. I need help with compiling the servlets given as part of the SERVLET tutorial. I have previously installed JDK1.3.1.01. I have also downloaded the JSDK2.1 as part of the tutorial. As part of the tutorial several servlet classes were provided. Almost all of them have these import statements.
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
However, the javac is unable to compile the classes. I think it is because javax.servlet is installed under /root/jsdk and JDK is installed under /usr/java/jdk1.3/bin. I can find the javax directory under /root/jsdk but not under /usr/java. I tried giving the classpath option to javac as:
javac -classpath /root/jsdk BookStoreServlet.java
But it did not work.
I believe once the servlet classes are compiled it will be possible to view them from the JSDK browser. I was able to successfully start the jsdk browser with startserver script given with the distribution. And the example SnoopServlet worked fine.
In summary, I believe the authors of the tutorial left out the details of compiling the classes and viewing from browser. I could be wrong about it.
I will appreciate any help from the users of the tutorial and anyone who knows servlets.
Many thanks.

i found this info on how to set the classpath in linux
http://java.sun.com/products/jdk/1.2/docs/tooldocs/sola
is/classpath-linux.htmlThanks imp-cat. I could compile the BookStoreServlet.java into its corresponding class. I get the following error when I try to run it. What should I do? Thanks. Regards. Murthy

Compiling a servlet with utility class

Hello,
I am having trouble compiling a servlet that uses a utility class.
The compiler doesn't seem to recognize the utility class for some reason.
my classpath is set to:
.;C:\ServletDevel;C:\Program Files\Apache Software Foundation\common\lib\servlet-api.jar
the error:
Cannot find symbol: ServletUtilities
the servlet code:
package coreservlets;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
/** test the use of packages and utilities on the server */
public class helloservlet3 extends HttpServlet {
public void doGet(HttpServletRequest request,
 HttpServletResponse response)
 throws ServletException, IOException {
 response.setContentType("text/html");
 PrintWriter out = response.getWriter();
 String title = "Hello (3)";
 out.println(ServletUtilities.headWithTitle(title) +
 "<body bgcolor=\"#FDF5E6\">\n" +
 "<h1>" + title + "</h1>\n" +
 "</body></html>");
the utility class:
package coreservlets;
import javax.servlet.*;
import javax.servlet.http.*;
/** time saving static methods */
public class ServletUtilities {
 public final static String docType =
 "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +
 "Transitional//EN\">";
public static String headWithTitle(String title){
return (docType + "\n" + "<html>\n" +
 "<head><title>" + title + "</title></head>\n");
any help wouldbe greatly appreciated.

Nope still getting an error
helloservlet3.java:17:cannot find symbol
symbol : class ServletUtilities
location: package coreservlets
out.println(coreservlets.ServletUtilities.headWithTitle(title) +
thanks for the help, i'll keep on trying to figure it out.

Help compiling with .class files

I am using JGrasp and I am trying to compile a program that uses .class files instead of the .java files, but JGrasp will not recognize these at compile time. How do I get my program to compile with these .class files?

I prefer using Jenuity:
[http://www.nmmu.ac.za/jenuityIDE]
It's much simpler to use than JGrasp and isn't nearly as confusing.
For the record, you compile .java files into .class files. There is no need to "compile" existing .class files. If you have the class files you can run them from the command line. e.g. if you have a class file named Orange.class you should be able to type "java Orange" from the command line to run it. If Orange is inside a directory structure based on packages you may need to execute this command from just outside the 'highest" folder.
If you just need to link to these class files, copy them into the "/jre/lib/ext" folder of your JDK.

10 Duke Dollars if you help me set up tutorial

After several posts to this forum w/o any success, I am now offering 10 Duke Dollars to get this problem fixed:
I am trying to work through the j2ee tutorial on a Windows XP platform, specifically the servlets section which requires me to build the bookstore1 example (chapter 11). I am having problems with using asant to compile and package the project. I have been at a complete standstill for about a week now because I cant get the example to run - Im tearing my hair out, so plese help me!!!
The command I am using is asant create-bookstore-war. This throws about 80 compilation errors because classes referenced within the source files are not found . I therefore know that the compiler cant find the classes (suggesting CLASSPATH problems), but I dont know what settings Im supposed to be using.
Some info for you:
I tried adding JAVA_HOME and J2EE_HOME to the environemt variables, pointing to the java sdk (inside the app server) and J2EE application server installation location respectively. This didnt work. Initially I had JAVA_HOME pointing to a seperate installation of the SE SDK I had, but since discovering the SDK inside the appserver, I uninstalled J2EE, J2SE SDK, and re-installed J2EE, using the enclosed sdk as JAVA_HOME. None of this solved my problem.
I think I know now that the environment variables are not anything to do with the tutorial - this is just for the locations of the J2EE and J2SE SDK command path files - is this correct? In which case, using J2EE_HOME and JAVA_HOME is just for shorthand declarations in the environemtn/system variables?
(As you can probably guess by now I have spent a lot of time trying out different things!!!).
I also tried setting the j2ee.home and j2ee.tutorial.home attributes in the build.propoperties file located in <INSTALL>/j2eetutorial14/examples/common. This didnt work. I also tried setting the admin username property in this file, and the corresponding password in the password file (cant remember offhand what its called). Again, no luck.
In another post, somebody asked for the following oputput from my system:

Heres the last couple of errors on running asant creat-bookstore-war. All errors are cannot resolve symbol, so im sure its a classpath problem.
I only have PATH properties set in the environment variables, and the set CLASSPATH only points to my own J2SE packages.

How to insert the new Servlet Api Class files?

Hi,
I need to know how do I add the Servlet Api Class to my java directory
after i download it from the net? Thanks for your help in advance!

niceguyme,
If you downloaded the J2EE 1.3.1 API and installed it to (for example) c:\j2ee131, then what you need to add to your class path is:
c:\j2ee131\lib\j2ee.jar
I also add c:\j2ee131\lib\ejb10deployment.jar to the classpath, but it is not necessary.
there are several ways to add these to your classpath. It depends on what Operating System you are using. On windows 98 type OS, you can edit the autoexec.bat and add these directly to your already existing classpath. Windows NT,2000, and XP: you can add them to the system environment variables classpath. Hopefully you know how to do this on your machine. What I like to do on the windows machine is create a batch file that will start it from within a command prompt. I do this because there are times when I need to compile my code using different versions of the Java api. I am enclosing an example of one for J2se1.4.1 and j2ee1.3.1.
contents of java141.bat
@ECHO OFF
ECHO JDK 1.4.1 and J2EE 1.3.1 are current versions

Trouble compiling a Servlet using the JSWDK-1.0.1

I have an old Win95 box on which I had a JDK 1.2 install and I then installed the JSWDK-1.0.1. I have the servlet.jar and jspengine.jar files in the "\lib" directory and have added them to my classpath.
I created a simple servlet but it does not read any classes from the JSWDK .jar files and throws an error saying class HTTPServlet not found. The first few lines of my servlet look like:
import javax.servlet.*;
import javax.servlet.http.*;
public class TestServlet extends HTTPServlet
Any idea why the "javac" compiler cant see the class from the proper jar file? I am using JBuilder as my source code editor and it too shows all the servlet related class/package names in red (i.e. doesnt recognize them).
Regular java apps compile and run fine on this machine.

Hi,
It should be definitely a CLASSPATH problem. You can double check the CLASSPATH in command prompt like this
echo %CLASSPATH%
If the CLASSPATH is set properly, you should see something like this
c:\jdk1.2\lib\tools.jar;c:\jswdk-1.0.1\lib\servlet.jar
Hope this helps.
Best Luck!

Compiling a Servlet that uses JavaBean

I have a servlet that will get data from a JavaBean which is created before in a jsp file. While I trying to compile the servlet I am getting this message:

Process completed.
Where is the problem. SimpleBean is successfully being initializing in my jsp file. But I couldn't compile my servlet that will get data from that bean. Both my servlet and bean are in the same package. I am using JCreator to compile servlets. I think the problem is the compile string that JCreator uses. Can you help me. Thx in advance.

Looks like an import Problem.
The Compiler is not able to "see" the SimpleBean Class.
Take care of the Classpath and your imports.
Happy Coding. :-)

How to compile a servlet

I have included the servletapi2_1_1-win package from the sun site containing the servlet.jar in my classpath. Still it refuses to compile. Besides does anybody know how to compile using the servlet packages available in Tomcat or j2ee, both of which I have on my machine , but can't figure what to include.
Please help.

have you actually included the servlet.jar file in your classpath or just the directory, as you need to explicity declare jar files in the classpath...
javac -classpath %CLASSPATH%;C:\[servlet-jar-path]\servlet.jar Servlet.class

Problem with Servlet Tutorial

I am going through the servlet tutorial with a specific end in mind. I found a section that I think relates exactly to what I want to do. I want to have servlet redirect the user to another URL. The following code is given as an example.
public class Dispatcher extends HttpServlet {
   public void doGet(HttpServletRequest request,
      HttpServletResponse response) {
      request.setAttribute("selectedScreen",
         request.getServletPath());
      RequestDispatcher dispatcher = request.
         getRequestDispatcher("/template.jsp");
      if (dispatcher != null)
         dispatcher.forward(request, response);
   public void doPost(HttpServletRequest request,
}The problem is that I can't compile this. There is no HttpServletRequest.getRequestDispatcher(String) method. Am I misssing something here? Am I even on the right track?

An extract from one of my servlets that redirects to
another URL is
this:response.sendRedirect(response.encodeRedirec
URL("NoLogon"));But it appears you want to
forward, rather than redirect. There's a difference,
but I don't exactly know what it is. The forwarding
example in my servlets book looks like
this:RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher(address);
dispatcher.forward(request, response);
I tried pasting your first example into my code and got the follwoing error:
Method encodeDirectURL(java.lang.String) not found in interface javax.servlet.ServletResponse
It seems like there is still something missing here. When I look at the API I only see four methods for this class.

What's the easiest way to compile a servlet?

What on earth is the easiest way to compile a servlet? I have ant and I know how to use it, but there has to be an easier way. I write my programs in Textpad and it'll only spit out errors when i try to compile:

I have my JAVA_HOME variable set to C:\j2sdk1.4.1_01 and my J2EE_HOME set to C:\j2sdkee1.3.1 and that is exactly where each are installed. How would a person compile a servlet say.. on the command line? It seems there would be an easier way than having to do a build file and all that. Any help would be greatly appreciated. I've written a lot of stuff that works great but for some reason this stuff is giving me fits. thanks in advance

I got 7 total errors that time, more than before, all of them dealing with packages in the j2ee. The classpath is 100% correct for the way I installed everything; I have checked it about three hundred times. Could htere be some other small detail I missed?
