doubt in run the servlet in tomcat 5.5

[joseph prabhu]

hello joseph here

In the classes folder i have servlet called lifecycle, which i compiled and have lifecycle.class file.

how to run. i request the url as

[URL=http://localhost:8080/website/lifecycle[/url]

it gives 404 error.

If you want to run the servlet directly by typing url in the address bar then the servlet should support doGet method. Secondly the url should be in accordance with the url-pattern tag of servlet mapping in web.xml

[Sagar Rohankar]

Have you mapped the servlet in your web.xml file as, If not then look at this !

[joseph prabhu]

where i can find the web.xml . did i have to write explicity in the WEB-INF directory.

[Sagar Rohankar]

Yes, you have to ! Its in WEB-INF/web.xml

[joseph prabhu]

without the web.xml the jsp program are running.

did i have to write the web.xml. for this . is there any way to create the web.xml automatically.

[Sagar Rohankar]

Yes, when we request the .jsp pages, its get compiled and retrued by servlet container to browser.

But the servlets are mapped by the URL pattern to actual stored Servlet class

e.g

 
 
<servlet servlet-name='lifecycle'
         servlet-class='test.lifecycle'>
  
</servlet>  // map servlet class  to servlet name
 
<servlet-mapping url-pattern='/lifecycle'
                 servlet-name='lifecycle'/>
//map url to servlet name
   

Here is the basic web.xml file from tomcat

[joseph prabhu]

is any command to create the web.xml automatically as like in weblogic server

[Sagar Rohankar]

No, as far as my knowledge is concerned there is no command to build web.xml from tomcat server, but you can use build tools like Ant and there are IDE like Netbeans which add the entry of each new Servlet class you creates !

But I suggest you crate or write the web.xml elements yourself, that makes your basic clears and helps in understanding the things !
