Struts 2 annotation error when calling action

Hi all I'm having problems using Struts 2 Annotated Actions

In my pom.xml I have:

<!-- STRUTS2 annotation -->
<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-convention-plugin</artifactId>
    <version>2.3.16.3</version>
</dependency>

<!-- STRUTS2 SPRING integration -->
<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-spring-plugin</artifactId>
    <version>2.3.15.1</version>
</dependency>

in my web.xml:

<filter>
  <filter-name>struts2</filter-name>
    <filter-class>com.agiletec.apsadmin.system.dispatcher.StrutsPrepareAndExecuteFilter</filter-class>
      <init-param>
      <param-name>struts.devMode</param-name>
      <param-value>true</param-value>        
      </init-param>
      <init-param>
      <param-name>struts.objectFactory</param-name>
      <param-value>spring</param-value>        
      </init-param>        
<init-param>
    <param-name>actionPackages</param-name>
    <param-value>it.aicof.projects.openMED.aps.internalservlet.actions</param-value>
</init-param>          
</filter>  
  
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/do/*</url-pattern>
</filter-mapping>
<filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/struts/*</url-pattern>
</filter-mapping>

I have two action classes:

@Namespace("/budget")
@SuppressWarnings("serial")
public class BudgetAction extends BaseAction {
    
    @Action(value = "/start", results = { @Result(name = "success", location = "/WEB-INF/openmed/aps/jsp/internalservlet/budget/budget.jsp") })
    public String start(){
.......


@Namespace("/upload")
@SuppressWarnings("serial")
public class UploadAction extends BaseAction {

    @Action(value = "/init", results = {
        @Result(name = "success", location = "/WEB-INF/openmed/aps/jsp/internalservlet/upload/upload.jsp")})
    public String init() {
        .....

if I call the first one http://localhost:8080/openMED/do/budget/start.action all works but when I call the second one http://localhost:8080/openMED/do/upload/init.action i get this error

 There is no Action mapped for namespace [/do] and action name [init] associated with context path [/openMED]. - [unknown location]

What's wrong? Two classes are configured in the same way.

According to the error message

2014-07-18 15:49:15,454 - ERROR - Dispatcher - Exception occurred during processing request: There is no Action mapped for namespace [/do] and action name [init] associated with context path [/openMED]. - [unknown location].

you have used url /openMED/do/upload/init.action but your action is mapped to the namespace /upload. A namespace is a path from the context path to action name. You can find more information about namespace configuration. You can also look at this example to better understand namespaces concept.

You should change action mapping

@Namespace("/do/upload")
@SuppressWarnings("serial")
public class UploadAction extends BaseAction {

@Action(value = "init", results = {@Result(name = "success", location = "/WEB-INF/openmed/aps/jsp/internalservlet/upload/upload.jsp")})
public String init() {
