Thanks for your help.

I put the Struts.xml file where you can see the Struts2 actions and the javascriptFunctions.js that contains de borrarPerfil() where as you can see I need to call Struts2 action

Struts.xml

<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />

    <action name="registrar" class="registrar.action.Registrar"

javascriptFunctions.js

function borrarPerfil() {
    if(confirm("Are you sure to delete this profile?")){
        alert("deleted");
       //CALL STRUTS2 ACTION borrar 

    } else {
        alert("no paso nada");
     //CALL STRUTS2 ACTION logout   
    }   
}

Answer 1

Finally, I solve how call from javascript function. It should be like this:

javascriptFunctions.js

function borrarPerfil() {
    if(confirm("Are you sure to delete this profile?")){
        alert("deleted");
        window.location = "/Barcelona_Business_World_v2/borrar";
    } else {
        alert("no paso nada");
        window.location = "/Barcelona_Business_World_v2/logout";
    }   
}

I was wrong because I used the next to call the strut2 action:

window.location = "${pageContext.request.contextPath}/logout";

I read that it's the correct way to do but I don't know why in my function fail. I will read more about contextPath.

Thanks.
