Reading prop file bean error

Hy guys, I am trying to read a properties file and dispay it on the screen, but I am having trouble with my bean filE

Here is my bean file :

<context:property-placeholder location="classpath:fisier.properties." /> 

<bean id="fisier.properties" class="projectt.proiect.App">
    <property name="mesaj" value="${Hello}" />
    </bean>

</beans>

MY classes are this:

public class SecondClass {

    private String mesaj;

     public String getMesaj() {
            return mesaj;
        }

     public void setMesaj(String Mesaj) {
            this.mesaj = mesaj;
        }

     @Override
        public String toString(){
            return mesaj;
        }
}

And the main:

public class App 
{
    public static void main( String[] args )
    {

        String confFile = "bean.xml";

          ConfigurableApplicationContext context = new ClassPathXmlApplicationContext(confFile);

          SecondClass secClass = (SecondClass) context.getBean("mesaj");
          System.out.println(secClass.toString());
          context.close();

}
}

I am getting the following error in the bean file : Attribute : name The name of the property, following JavaBean naming conventions.

Data Type : string

Can someone help me with this?
