Hi,
Here I am assuming that you have already downloaded and intalled the tomcat on your machine and you are able to access http://localhost:8080. On typing http://localhost:8080 your browser shows the tomcat?s default page.
Now I am going to explain you the process to create web application, write hello world jsp file and then check on the tomcat server.
Step 1:
Stop the tomcat
Step 2:
Go to tomcat?s webapps directory and create the following directory:
[tomcat-root]/webapps
|_ test
|_ WEB-INF
|_ classes
here test is the name of web application.
Step 3:
Now create hello world jsp page in the test directory. Here is the code of hello.jsp
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE>Hello World</TITLE>
<BODY>
<%="Hello World!"%>
</BODY>
</HTML>
Step 4:
Now Start the tomcat server.
Step 5:
Now you can test your application. To test the example type http://localhost:8080/test/hello.jsp
You browser should display the hello world message.
Hope you will help in getting started with JSP in tomcat.
Thanks

Hi, Here is the code of web.xml: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">; </web-app> Save the web.xml file into WEB-INF directory. You can declare your servlet into web.xml file. <!-- Hello World Servlet --> <servlet> <servlet-name>HelloServlet</servlet-name> <servlet-class>HelloWorld</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>HelloServlet</servlet-name> <url-pattern>/Hello</url-pattern> </servlet-mapping> To access the servlet you have to type http://localhost:8080/test/Hello into browser. Thanks
