HelloServlet not running ?

[raghu tv]

i am using Tomcat 4.1
i am able to run HTML and JSP from browser.
But i am unable to run the servlet........
i kept the HelloServlet.class in the
Tomcat\webapps\ROOT\WEB-INF\classes.
and http://localhost:8080/servlet/HelloServlet
is not working.Actually there was no classes
directory in WEB-INF i created it and kept the class file in it. is that it wont work with higher versions of Tomcat ? then what i have to do......

You have to prepare a web.xml file and put it in the WEB-INF directory to run servlets. Here is an example of web.xml:

  
<?xml version="1.0" encoding="ISO-8859-1" ?> 
  <!DOCTYPE web-app (View Source for full doctype...)> 
- <web-app>
  <display-name>Welcome to Tomcat</display-name> 
  <description>Welcome to Tomcat</description> 
- <servlet>
  <servlet-name>HelloServlet3</servlet-name> 
  <servlet-class>moreservlets.HelloServlet3</servlet-class> 
  </servlet>
- <servlet-mapping>
  <servlet-name>HelloServlet3</servlet-name> 
  <url-pattern>/servlet/moreservlets.HelloServlet3</url-pattern> 
  </servlet-mapping>
  </web-app>

thanku for the response
i kept your web.xml in WEB-INF directory but already a web.xml file is there in it anyhow i kept both the xml files but still i am getting the 404 error

I think you can do one of two things.
1. Use servlet mapping in the web.xml of your web application like JiaPei Jen began explaining.
2. In tomcat's web.xml under the /conf directory. You can uncomment the mapping for invoker servlet and then it should work like were hoping in your first posting with http://localhost:8080/servlet/HelloServlet.
Here is a link where they addressed the same problem, and the explanation is in more capable hands than mine. https://coderanch.com/t/82236/Tomcat/requested-resource-not-availabe

[raghu tv]

once again thank u for ur response.Both the things didnot work....
1)i made the web.xml as follows in WEB-INF directory
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
-<web-app>
<display-name>Welcome to Tomcat</display-name>
<description>
Welcome to Tomcat
</description>
- <servlet>
<servlet-name>HelloServlet</servlet-name>
<servlet-class>HelloServlet</servlet-class>
</servlet>
- <servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/servlet/HelloServlet</url-pattern>
</servlet-mapping>
</web-app>
but still my servlet is not working .
2) i removed the comments for the invoker servlet in tomcat's web.xml under conf directory
but still it ia not working
3) and the link u gave is very complex to understand .please help me in solving the problem

take those '-' out of your web.xml file. IE will add little plus and minus signs to XML files when it displays in a browser. If you copy and paste directly, you get the - and + symbols. It's not good to have them.

hi,
i had encountered same problem with 4.1 vers.
then i changed location from the one to <HOME>/
webapps/examples/WEB-INF/classes for testing
purpose & it worked fine. then u need to
configure server.xml,web.xml to make ur own
pckgs.
dont forget to change context path.type in brw.

good luck.

raghu tv,
Take another look at the aforementioned thread. I just posted the exact steps I used to resolve this issue on my installation of Tomcat 4.1.
Oh, and...
