404 - Request resource is not available - Spring MVC

Question

I'm trying to use Spring framework in my website but I'm having troubles while trying to set it up. I know a lot of people has asked something similiar to my question, but I couldn't have my problem solved with all the hints I've seen.

Please refer below for my code which tries to open an .jsp file using Spring framework.

@Controller
public class OlaMundoController {

    @RequestMapping("/olaMundoSpring")
    public String execute() {
        System.out.println("Executando a lógica com Spring MVC");
        return "ok";
    }
}

ok.jsp

<html>
  <body>
    <h2>Olá mundo com Spring MVC!</h2>
  </body>
</html>

My Project

enter image description here

I'm using localhost:8080/WebProjetoFinal/olaMundoSpring to access.

What could I be missing here?

EDIT:

Here's the full stack trace when I'm initializing my TomCat server or trying to access the page. (The exceptions are the same in both case)

There are few thing you can check, 1) is there any warning in there in ther server logs 2) is the controller loaded (You can create a default constructor and put a `sysout` stmt there to see whether it is actually loaded) — Arun P Johny, Mar 02 '13 at 00:50

it looks like some sort of compilation problem see this http://stackoverflow.com/questions/1980452/what-causes-java-lang-incompatibleclasschangeerror — Arun P Johny, Mar 02 '13 at 01:43
Yes.. it was.. My Jars files of Spring framework were crashed. I'm using version 3.0.5 now and it finally works! Thanks all — Felipe Mosso, Mar 02 '13 at 03:02

I think your servlet mapping should actually be this:

<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Yeah. Sorry, my current version is in the way you said, but it still doesn't working. But thanks! I've edited my question – Felipe Mosso Mar 02 '13 at 00:26

I believe you are missing the file springmvc-servlet.xml

This file is derived from name of your dispatcher servle plus "-servlet.xml"

Also, try moving your component-scan and your bean definition to the springmvc-servlet.xml file.

copy and paste the spring-context.xml and rename it to springmvc-servlet.xml
move the component scan to the springmvc-servlet.xml
move the bean definition to the springmvc-servlet.xml
have your serlvet mapping map to "*.mvc"
have your web page call /olaMundoSpring.mvc, this will invoke the dispatcher servlet

Moving forward... (optional) Also consider using maven. It will save you from having to hunt down jar files on the internet. It will manage your dependencies automatically.

I don't understand what you mean. But I've created an springmvc-servlet.xml and copied all the content of my old spring-context.xml to it. I've also removed the declaration of spring-context.xml in web.xml but the error persists – Felipe Mosso Mar 02 '13 at 00:30
keep the spring-context.xml declaration, it's needed. – Joe Wilson Mar 02 '13 at 00:36
now i'm getting this error: org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: – Felipe Mosso Mar 02 '13 at 00:56
move mvc:annotation-driven to the -servlet.xml file and see if that fixes it. Otherwise, provide the full stack trace. – Joe Wilson Mar 02 '13 at 01:02
it seems like your web.xml is not in the WEB-INF folder. Is this true? – Joe Wilson Mar 02 '13 at 01:14
Yes, it wasn't. Now i put it in it. But the problem continues :( – Felipe Mosso Mar 02 '13 at 01:20

Try these

Remove spring-asm-3.0.3.RELEASE.jar and see if it works.
If the above suggestion do not work, instead of spring-asm-3.0.3.RELEASE.jar download spring-asm-3.1.4 jar from here and add it to your lib

I was using Spring 3.1, migrated to Spring 3.2 getting following error:

nested exception is java.lang.IncompatibleClassChangeError: class
org.springframework.core.type.classreading.ClassMetadataReadingVisitor has interface 
org.springframework.asm.ClassVisitor as super class

solution: Exclude asm from the cxf dependency

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-bundle-jaxrs</artifactId>
    <version>${cxf.version}</version>
    <exclusions>                
        <exclusion>
            <artifactId>spring-asm</artifactId>
            <groupId>org.springframework</groupId>
        </exclusion>
    </exclusions>
</dependency>

similaryly, exclude asm or other jar which creates the problem

Your spring-asm jar seems to be the wrong version. Try spring-asm-3.1.1.RELEASE.jar.

The only other thing I can see is in web.xml, change init-param to

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/spring-context.xml
    </param-value>
</context-param>
