Error The requested resource is not available

[Mark Chan]

I am trying to learn Spring MVC, and I've followed the tutorial in http://static.springsource.org/docs/ to build my first spring project and so far everything was going OK up to the Deploy step then when I tried to test it using the URL: http://localhost:8080/springapp/index.jsp

I got the following error:

HTTP Status 404 - /springapp/index.jsp

type Status report

message /springapp/index.jsp

description The requested resource (/springapp/index.jsp) is not available.

So can someone please tell me what I might doing wrong?

Thanks for your time and help

Note: I have Apache, Tomcat 6, Ant installed and running

Please TellTheDetails.
Post the server log files and with relevant code snippets. First, we need to see, if the application is deployed successfully.

The link I provided earlier contains all the code, I've just copied and pasted code from the website 'as is'. If you want me to copy and paste the code from the website to here again, i really have no problem in this yet I thought it will be like stuffing the post with code which is already in the link

Regarding the log files, any idea what kind of log files you are looking for? I am pretty new to Spring and web apps and still learning so i am not sure what type of log files you are looking for, yet I will be more than glad to get them once I know which log files

Thanks for your time

I will see the code from that link, can you please post the logs from file located under your tomcathome/logs, file will be named catalina-<date>.log.

P:S: If you are very new to web applications, I would suggest you first learning Servlets and JSP's first, because servlets are the building blocks of any MVC framework.

Thanks a lot for your advice and help. I've no problem in learning Servlet, JSP...the problem all raised when I tried to test

I don't see the application getting deployed at all. Where have you placed the war file, is it under tomcathome/webapps? Also, you can try restarting tomcat, once you place the war file under webapps.

As per the tutorial in http://static.springsource.org/docs/Spring-MVC-step-by-step/part1.html I've deployed it using ANT and i can clearly see it under /usr/share/tomcat6/webapps/

There is no war file there, if you checked the tutorial in the link you will notice I am just testing a simple JSP file with static text This is a very basic spring tutorial, and it is like the first step in the tutorial...please check it to know what I am referring to

Thanks for your help!

[Mark Chan]

I just wanted to add that I've tested Servlet / JSP examples that come with Tomcat and all work OK, which means that Tomcat is running without a problem

[Prasad Krishnegowda]

From the link you posted. please post the output when you follow section 1.4. i.e ant list.

As you can only see, the springapp example is not deployed. Can you please try restarting the tomcat, after you run the ant script to deploy the application.

I have done so many times and same result Actually this is my problem from the start which is the I keep trying, restarting and nothing happens which make the problem even weirder

This is all I have here

Thanks for your help

[Mark Spritzler]

You could also just manually copy the war file to your webapps directory and bypass ant if ant isn't doing the copying correct.

Looking at your properties

# appserver.home=${user.home}/apache-tomcat-6.0.24
appserver.home=/usr/share/tomcat6
# for Tomcat 5 use $appserver.home}/server/lib
# for Tomcat 6 use $appserver.home}/lib
appserver.lib=${appserver.home}/lib

deploy.path=${appserver.home}/webapps

Are those directories correct? Is your tomcat installed at /user/share/tomcat6?

[Mark Chan]

I found it now it works

See the problem is that we never thought when deploying the command shall be
ant build
OR
ant buildwar

with the last one, I was able to build war file which was placed in /usr/share/tomcat6/webapps/

then from the tomcat6 manage I just selected the war file, deployed it and voila it worked

Thanks a lot for your time and help
