problem in deploying the webapplication on a web server

[kris_121]

Hi friends,
Iam trying to deploy a simple java web application(servlet)..it gives me the following error in the browser:
type Status report
message /hello
description The requested resource (/hello) is not available.

I tried deploying on tomcat and java web server...it is able to open html files..Kindly help me out..

Thanks,
Kris

Please cross check the directory in which you are placing your servlet. Generally both HTML and Servlets don't sit in same directory in servers.

Thanks,

Hi Kris,

Did u specify the Servlet name and Servlets mapping in the web.xml file in the WEB-INF folder. If not you have to specify, that is why it is giving that error message "requested resource is not available". for HTML and JSPs you dont need to specify them in the web.xml, the web container automatically takes the pages in the web appn folder when you give the context root.

Please let me know your questions

Thank You

Hi Kris,

Pls get the log the and paste it over here, I 'll examine it and let u know the problem.
To get the logs ,go to your tomcat folder/logs and get the jakarta_service.log and localhost_latestdate.log and paste it over here or attache the log files over here, I'll tell u what the problem is

Let me know your questions

The problem is of the Context creation. Please do the following
First uncomment the context which you are currently working.
second start your web server check whether it is starting properly or not
if it started properly then un comment the context
and again restart the app server
For commenting and un commenting the context of your application
see server.xml file in tomcat-home/config folder
do this and one more thing i observed from the discussion is the context is not created properly in your app server try to do resolve the context problem.

It went well starting up the web application. When I start the servlet the problem arises.I tsimply gives the following message:
HTTP Status 404 - /KrisWApp/
--------------------------------------------------------------------------------
type Status report
message /KrisWApp/
description The requested resource (/KrisWApp/) is not available.

--------------------------------------------------------------------------------
Apache Tomcat/5.5.16


I even uncommented the servlet invoker in TomcatHome/conf/web.xml.but of no use.other sample servlet applications,which come along with Tomcat, are also not running, they are alos giving me the same error.Please help me out.

Thanks,
Kris

Hi Kris,

If the example web applications are also not working ,then it not a problem in deploying the webapplication. it is the problem of the tomcat, some thing has gone wrong with the server itself.

Re-install your tomcat web server again, make sure that sample web applications are also working and then deploy your web application.

Let me know your questions

Thank You
