[ HELP!!! ] Ultra Simple Souce Code Running Problem

[eva500]

Hi, I'm a spring newbie.
I'm trying to run a very simple project in STS run on Server. http://localhost:8080/springbook/hellospring.jsp
There is no errors in Console when I run it, but I got the following message
================================================== =================
HTTP Status 404 - /springbook/hellospring.jsp

type Status report

message /springbook/hellospring.jsp

description The requested resource (/springbook/hellospring.jsp) is not available.
================================================== =================
I attached the zipped project file.
Could you please take a look and let me know what was wrong with it.
(Note: I removed all related .jar files in WEB-INF/lib since they are too big to be attached)

You have no JSP files in the WebContent directory. You only have them in the WEB-INF directory. A request to /springbook/hellospring.jsp will return a 404 because there's nothing at that url.

Thank you for letting me know.
After I put hellospring.jsp file in WebContent Directory, I got another errors when I click http://localhost:8080/springbook/hellospring.jsp as follows
I google it to fix this problem, but couldn't find.
Could you please let me know again what was wrong in this case?

Actually, when I 'run on server' in STS, HelloSpring.class file was not automatically created.
So I just manually compiled HelloSpring.java in the command line,
then I created directory manually in the command line under WebContent --> WEB-INF-->classes --> springbook --> temp
and then put HelloSpring.class under the WebContent --> WEB-INF-->classes --> springbook --> temp --> HelloSpring.class

It looks like your source tree isn't added as a source tree in the project, or perhaps it doesn't know it's a web application.

It also sounds like you're including the "javax.el.*" package in your webapp. I believe that the container should be providing that. I think you should remove that jar from your webapp.
