This week's book giveaway is in the Agile and other Processes forum. We're giving away four copies of The Mikado Method and have Ola Ellnestam and Daniel Brolund on-line! See this thread for details.
Hi I have created a chapter01 directory under C:\jakarta-tomcat-4.1.18\webapps Next, I created a WEB-INF directory under C:\jakarta-tomcat-4.1.18\webapps\chapter01 I developed a HelloWorldServlet, the code is as follows:
I compiled the servlet and copied it under C:\jakarta-tomcat-4.1.18\webapps\chapter01\WEB-INF\classes The C:\jakarta-tomcat-4.1.18\webapps\chapter01\WEB-INF also has web.xml
I started the tomcat as follows: C:\jakarta-tomcat-4.1.18\bin>startup I opened the browser and typed the following url http://localhost:8080/chapter01/servlet/HelloWorldServlet I got the following response: description The requested resource (/chapter01/servlet/HelloWorldServlet) is not available. What must be the reason? Thanks Ravi

Use <servlet-mapping> in the web.xml file it will work. <servlet-mapping> <servlet-name>HelloWorld</servlet-name> <url-pattern>/HelloWorld</url-pattern> </servlet-mapping> BY! gurcharan

Hi Gurucharan What url must be used to invoke the servlet mapping? I guess that url pattern modifies the root context. Thanks Ravi

The <servlet-mapping> tag is required with Tomcat 4.1.18 - it wasn't previoulsy so it can cause some confusion since previous versions of Tomcat (4.0.x, etc.) did not require this tag.

Put the below servlet mapping in web.xml and this will lead your all servlet to execute without doing servlet mapping individually <servlet-mapping> <servlet-name>invoker</servlet-name> <url-pattern>/servlet/*</url-pattern> </servlet-mapping> BY! guru

I had the same problem with tomcat-4.1.24. Uncommenting the code (gurcharan singh above refers to) in %CATALINA_HOME%\conf\web.xml solved the problem.
