Getting 404 Error when deploying ROO project on Server in STS

[fortm]

I was following tutorial from "Getting Started with Roo" book and everthing went fine until I began moving project root to server, when error 404 is coming..

persistence setup --provider HIBERNATE --database MYSQL --userName root --password
entity --class ~.model.Customer
field string --fieldName lastName --notNull
field string --fieldName firstName --notNull
database reverse engineer --package ~.domain --schema rootest
controller scaffold --entity ~.domain.Customer --class ~.web.CustomerController

scaffold command ended successfully, I am not able to undersnand why this URL is giving 404 error -
http://localhost:8080/crm/customers

CustomerController ->

@RooWebScaffold(path = "customers", formBackingObject = Customer.class)
@RequestMapping("/customers")
@Controller
public class CustomerController {
}

Server Log message:

Also "perform eclipse" command sys -

OK.. i was able to workaround this by first manually adding log4j jar to library with same version as before.
Then, somehow tc server is not able to run the project that I created.

So, ran it as a maven build with command as "-e clean tomcat:run" and it runs..

But, there is another thing I have to fix.
When I run project for first time, tables were created for different entities. But, data is not persisted between runs.
So, closing tomcat and running a new is creating new tables and deleting data every time stored from before.

Please suggest on this.

I have 2 controllers - PageController and ArticleContoller.
So, there are 2 entity - articles and pages

I think I am replying myself ..
Anways, since I figured out solution for persistence, I am posting it here -

I changed "hibernate.hbm2ddl.auto" property from create to validate as below -

            <property name="hibernate.hbm2ddl.auto" value="validate"/>

This ensures that data is not deleted between runs.

Try:

C:\Users\viji>mvn -version

If you see something like:

Apache Maven 3.0.2 (r...)
Java version: 1.6.0, vendor: ...
Java home: C:\Program Files\Java\jdk1.6.0_...
Default locale: es_ES, ...
OS name: "windows vista"...

I don't know the problem.

Otherwise, install maven (or add the mvn.pat to the PATH), because it's necessary for Roo.

In STS, the maven plugin adds a Maven library that contains the maven dependencies as JARs, so you don't need to add them manually. In fact, in a web application they will be included in the war file, in the WEB-INF/lib (unless you avoid it with some configurations in the maven-war-plugin).

Because in STS with the maven plugin you can (right button click):
1.- Configure your project as a maven project.
2.- Update project configuration (and dependencies)
3.- Add the project to the TC Server that comes with STS
4.- Deploy, run, and go to http://localhost:8080/crm/customers

I hope it helps you.

Thanks jbbarque As soon as I added path for maven in Environment Path and then also had to add JAVA_HOME ,internal server started working. I had to also do "update Maven Project Configuration" for the project. But, I am faced with anoher problem for which I opened a thread - "http://forum.springsource.org/showthread.php?123870-Unable-to-run-database-reverse-engineer"

To start with, I am not able to do - "database introspect --schema rootest"
Even though it was working before. I had once successfully reverse enginner using ROO.
Then, I deleted those classes. It is not working now asking me to install same extension every time..
