Guys i am completely new to this servlets stuff and am reading it from Head first servlets and JSP.
Currently i have the servlet code ready.
The book uses command prompt for all compiling,etc but i have always used eclipse till date.But as i am new to this stuff this time i decided to do everything as the book says as i have no idea how to do all the servlets stuff in eclipse.
Before we are running servlets we need to do many things. here the following example helps a lot for running servlets from command prompt.
Creating a Servlet without any IDE I want to show how to create a simple servlet without using any IDE like NetBeans or Eclipse. I will use Tomcat 6.0 and Notepad to create a simple test servlet and run it.
The article assumes, you have JDK 5.0/6.0 and Tomcat 6.0.
The following are the steps to be taken by you to create a simple servlet.
Download Tomcat 6.0 from http://tomcat.apache.org Install Tomcat 6.0 into c:\ApacheTomcat6.0
Go to webapps directory of Tomcat and create the following directory structure for demo application. Any directory placed with required structure of Java EE web application is treated as a web application by Tomcat.
Creating Servlet Source Code
The following is the code for TestServlet.java. It simply sends a message to browser.
Deployment Descriptor - web.xml
Create web.xml as follows. It is better you copy web.xml from some other application in Tomcat webapps directory instead of typing it from scratch. Make sure it is placed in WEB-INF (in uppercase) folder of demo application with the following content.
TestServlet is associated with url pattern /test in web.xml. From the client, we have to make request for url pattern /test.
Go to classes directory, where .java file is placed as enter the following commands at the command prompt to compile the servlet.
Make sure you change JDK and Tomcat directories according to your installation.
Set path to the directory where JDK is installed. Servlet-api.jar contains API related to servlet like HttpServlet, HttpServletRequest etc., so it must be placed in the classpath. Compile the servlet (.java) to create .class file.
Starting Tomcat and Running Servlet
Start Tomcat by taking the follwing steps from BIN directory of Tomcat.
Once, tomcat is successfully started, go to browser and enterer the following URL.

Since you are new, I have added code tags to your post, and you can see how much better it looks Please avoid very long lines in code; the left-to-right scrolling makes them difficult to read.

Hey thanks a lot.I did all the steps as you said but this is the error i get:
This may be a five year old discussion, but I just wanted you to know that the clear instructions here just saved my life! I got these little bits and pieces of instructions from all over, but the way you put it all together here made the whole thing finally work! Thank you for really getting the ignorance of newbies....
