[Building Sakai] why i can't use sakai service in my app :( ?

[Small Cat]

Ok,
In ExternalLogic class, I add a function
*public String getOneSite(String locationId);*

In ExternalLogicImpl class ( I copy from function getLocationTittle )
*public String getOneSite(String locationId) {
        String title = null;
        try {
            Site site = siteService.getSite(locationId);
            title = site.getTitle();
        } catch (IdUnusedException e) {
            log.warn("Cannot get the info about locationId: " + locationId);
            title = "----------";
        }
        return title;
    }*
In main class, I call it
*public String getOneSiteTitle(){

        return
externalLogic.getOneSite(externalLogic.getCurrentALocationId());
        //return
externalLogic.getLocationTitle(externalLogic.getCurrentALocationId());
    }*
In .jsp file ( I use JSF to presentation )
*<sakai:instruction_message value="Hello,
#{MyportfoliosBean.oneSiteTitle}"/>*

Thank you very much ,
