Problem getting simple servlet to run in tomcat

i am trying to get a servlet to run that is explained in wrox Professional JSP second edition. i am using tomcat as the book explains.
1. i have created the ch03/WEB-INF/classes directory within the webapps folder in tomcat.
2. in the classes folder i created the directory
com/wrox/projsp/ch03/myfirstwebapp.
3. in the folder myfirstwebapp i have the compiled file
MyFirstServlet.class
4. i made sure the code is exactly as in the book.
5. it states that if i go to
http://localhost:8080/ch03/servlet/com.wrox.projsp.ch03.myfirstwebapp.MyFirstServlet i should get the correct output.
6. the only way i can get this to work is if i create a web.xml
file and point it to
com.wrox.projsp.ch03.myfirstwebapp.MyFirstServlet and then in the
browser i type in
http://localhost:8080/ch03/com.wrox.projsp.ch03.myfirstwebapp.MyFirstServlet thus leaving out /servlet in the URL
7. this seems fine but i would like to get it to work how the book shows which is without having to use the web.xml. am i missing something? do i need to set up anything (eg. a context tag for this app)within the server.xml.
any help would greatly be appreciated,
gary bushek

I don't know how the book you're using instructed you to setup the server but my web.xml simply has the following in it:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
</web-app>
I'm using tomact 3.2 and am able to run my servlets using
http://localhost/servlet/package_name.servletName

Just can't run HELLOWORLD servlet on Tomcat!

Hi there, I worked with servlets all summer long and now I'm getting back to build one, and I'm totally confused... My problem's there :
I try to run a simple HelloWorld servlet on Tomcat 4.1, and I get a 404 Error - Not found
Well, here's the structure of my web application, contained in simpleservlet.war :
WEB-APP
-web.xml
-CLASSES
-servlet.class
-LIB
-servlet.jar
Here's now the content of the web.xml file :
<web-app>
     <servlet>
          <servlet-name>serv</servlet-name>
          <servlet-class>servlet</servlet-class>
     </servlet>
     <servlet-mapping>
          <servlet-name>serv</servlet-name>
          <url-pattern>/test</url-pattern>
     </servlet-mapping>
</web-app>
AND FINALLY here's how I invoke my servlet, I TRIED :
http://localhost:1977/servlet/test
AND ALSO
http://localhost:1977/test
AND BANG, I GET "ERROR 404 - NOT FOUND"
A little help would be appreciated A LOT, well it's not supposed to be a hard problem... and by the way, I'm using port :1977, the problem's not there though.
regards, Pierre

Hi,
First try http://localhost:1977 and see if you are getting Tomcat. As you said, this is not a problem. So, you should get the index.html of the Tomcat. Now, click on the one of the example. From the Address Bar, you will know the path of this example. Try putting your page at that location and then run.
This should work.

Problem Running my servlet

Hi,
I use Tomcat 5.5.17 to run servlets. I can run the example servlets that come with Tomcat successfully. I have configured the java_home and class path variables. When I create a new servlet in the webapps/servlets-examples folder, I can run it.
However, when I try creating a new folder under webapps (named trial) and when I try to run my servlet from there I get the 404 Servlet not found error.
The steps I followed are:
1.Created a new folder trial under C:\apache-tomcat 5.5.17\webapps
2.Created the WEB_INF folder under trial and then the classes folder under it.
3. Put my servlet HelloServlet.class under the classes folder.
4.Put WEB.XML under the C:\apache-tomcat 5.5.17\webapps\trial\WEB_INF folder and made the following entry
<servlet>
<servlet-name>HelloServlet</servlet-name>
<servlet-class>HelloServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/HelloServlet</url-pattern>
</servlet-mapping>
5. I tried to access my servlet using the following URL:
http://localhost:8080/trial/HelloServlet
and that gives the 404 error.
Are there any additional steps when we are running a servlet a folder we create?
I searched the internet and found something about setting the context path but I could not understand how to do it for Tomcat 5.5.17 as the documents I found on the net were for older versions.
I would be grateful if someone could help me out. Thanks in advance!
Aniticipating your help!
Thanks and Regards,
Asana

Hi.. You can check your application context path through Tomcat Manager application.
URL is :
http://localhost:8080/manager/list
or
http://localhost:8080/manager/html/list

Problem compiling simple servlet

I am trying to compile a very simple servlet.
When I do, I get the following error message:
Package javax.servlet does not exist
I am using the Java 2 SDK, Standard Edition Version 1.3.1.
I have downloaded the servlet api (zip file servletapi2_1_1win.zip)
from Sun's site. I unzipped these files in my lib directory; there are two folders,
one called api and the other called src. Api and Src directories have their own
sub-folders, javax/servlet/http etc.
I am using W2K ; I had to create a CLASSPATH system variable in the environment
variables section of control panel since there was none defined.
I added the following line:
C:\jdk1.3.1_01\lib\api\javax\servlet;C:\jdk1.3.1_01\lib\api\javax\servlet\http;
I also did this for the PATH statement..
My servlet looks like this:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class howdy 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><TITLE>Hello World </TITLE></HEAD>");
out.println("<BODY>");
out.println("<BIG>Hello World </BIG>");
out.println("</BODY></HTML>");

Thanks. I was able to figure it out by specifying the
full classpath
at the command line, like this:
C:> javac -classpath
C:\jdk1.3.1_01\lib\servletapi2_1_1-win.zip\MyServlet.ja
a
Apparantly the system doesn't acknowledge the
environmental variable that
I created in the control panel; also I have no
autoexec.bat file...so it
looks like I have to write out the full path whenever
I need to compile
something. Kind of bothersome, but at least it
works.
You shouldn't have to do this. What operating system are you using?
If you are using win2000, winNT or winxp, you should set the classpath in your system environment varialbes. You can also make a config.bat file and put everything in there. Then just run this config.bat file to set up your environment once for every session.
Here's a file that I have set up on one of our NT machines. I just double click the icon for this file on my shortcut, and it gives me the window where I can compile my java programs.
Hope this helps.

Cannot run a servlet using Tomcat. Urgent

I have a webapplication which uses some jsp's and servlets. The jsp pages work fine when I use
http://hostname:8080/MyWebapp/Filename.jsp
However, when I developed a java servlet and put the class file in WEB-INF/classes directory of my web application and tried to access it.
I got a resource not found error.
The strange thing is that when I put the file in the web-inf/classes folder of examples webapplication (which comes with Tomcat) I am able to run the servlet using
http://hostname:8080/examples/servlet/Class file
I am not sure what is wrong.
Can someone help me.
Thanks in advance
Vamsi.

It's predictable. The Servlet and JSP specifications mandate that you cannot directly access resources under WEB-INF directory. You have to set up servlet mapping configuration in your web.xml to specify how to access the resources, both Servlet and JSP, there.
When you copied your files in a demo webapp of Tomcat, the web.xml of the demo app already set up the mapping like following for you. So you could use http://hostname:8080/examples/servlet/Class to visit the servlet.
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
The default setting since Tomcat 4.1 turned off servlet invoker in web.xml under conf directory. You can uncomment the above lines in this file to turn it on. Then you are able to visit your servlet without <servlet-mapping> configured using the following syntax,
http://hostname:8080/<your_app_name>/servlet/<your_servlet_name>

now start the server and type the url like : "http://localhost:8080/TestApp/TestServlet"
the port no. 8080 is the default port no. of tomcat. you have to give your port no. if u've modified it. and TestServlet is the <url-pattern> of your servlet.
go through some tutorials .. then you can easily know that

How can I run a servlet with tomcat

I'm a new learner in servlet,I recently write a servlet program,when I compile it,the compiler throws the error
"package javax.servlet.http does not exist",I have put the servlet.jar(which exist in d:\tomcat\bin directory) file into the classpath directory;my servlet source files are in D:\tomcat\webapps\mywork\web-inf\classes\com\stardeveloper\servlets;
"com.stardeveloper.servlets" is the package for my servlet source files,so I have write the sentence "package com.stardeveloper.servlets;" in my servlet source file.
I don't know how to resolve this problem.can you give me a help?

servlet.jar doesn't exist in the folder you mentioned, but rather, in C:\tomcat40\common\lib, so this should be included in your classpath, the other thing you should care about is how you compiled your servlets, so that the package statement match the hirarchy of the file.

Having problem running a servlet program in Tomcat5.5

Hi,
I wrote a sample servlet, HelloWorld.java and I compiled it and put the .class file in the WEB-INF\Classes directory in the Tomcat directory. Now when I do this,
http://localhost:8080/ it's working fine but when I do this, http://localhost:8080/servlet/HelloWorld I am getting an error message "*HTTP Status 404"*.
I have done no changes to web.xml and server.xml. Should I be doing anything?
My HelloWorld.Java file is as below.
package Users.Ravi.Desktop.CurrentProject.Servlets;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {
    PrintWriter out = response.getWriter();
    out.println("Hello World");
}Thanks.

Ah, I see the problem now. You need to put servlet class as
<code class="jive-code jive-java">Users.Ravi.Desktop.CurrentProject.Servlets.HelloWorld</code>
<code class="jive-code jive-java">So, your web.xml will have</code>
<servlet>
     <servlet-name>HelloWorld</servlet-name>
     <servlet-class></code><code class="jive-code jive-java">Users.Ravi.Desktop.CurrentProject.Servlets.HelloWorld</code><code class="jive-code jive-java"></servlet-class>
</servlet>{code}

Steps to create your directory and work in Tomcat 4.1
1.     Create your directory in Tomcat�s webapps Directory.
-----If your tomcat is in d:\ the your directory may look
----- D:\tomcat\webapps\<your directory>
     ------E.g. �d:\tomcat\webapps\test�
2.     In the test directory you can your html files directly or you can create a
directory to hold html files.
     --------E.g. �d:\tomcat\webapps\test\first.html (OR)
-------E.g. �d:\tomcat\webapps\test\html-files\first.html�
3.     Create a folder called WEB-INF inside test
-------E.g. �d:\tomcat\webapps\test\WEB-INF
------ Under the WEB-INF folder put your web.xml file
4.     Create another folder named classes under the same test
----- E.g. �d:\tomcat\webapps\test\classes
----- Here you need to place your servlet classes
----- E.g. �d:\tomcat\webapps\test\classes\testServlet.class
5.     Start any browser that are java enabled
6.     Type �http://<machine name (or) IP add.>:8080/<your folder
name>/<html file>�
----     E.g. http://localhost:8080/test/ html-files/first.html
-----E.g.http://127.0.0.1:8080/test/html-files/first.html
7.     Click the component (button, label�) to enable servlet
8.     That�s all! Now you should get your servlet executed.
Files:
1.     web.xml

Hi.
as Raphael says, check your libraries.
I think that adfpage is in adf-richclient-api-11.jar, check if this library is in your %CATALINA_HOME%/lib folder.
Anyway I will inform you that Tomcat is not a certificate server,http://www.oracle.com/technetwork/developer-tools/jdev/index-091111.html#Application_Servers
