From spring documentation:

5.10.6 Naming autodetected components

When a component is autodetected as part of the scanning process, its bean name is generated by the BeanNameGenerator strategy known to that scanner. By default, any Spring stereotype annotation ( @Component, @Repository, @Service, and @Controller) that contains a name value will thereby provide that name to the corresponding bean definition.

If such an annotation contains no name value or for any other detected component (such as those discovered by custom filters), the default bean name generator returns the uncapitalized non-qualified class name. For example, if the following two components were detected, the names would be myMovieLister and movieFinderImpl:

@Service("myMovieLister") 
public class SimpleMovieLister { }

@Repository 
public class MovieFinderImpl implements MovieFinder { }

Try to use compteMarcheService instead of CompteMarcheService.

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="exposedContextBeanNames">
    <list>
      <value>compteMarcheService</value>
    </list>
  </property>
</bean>

<c:set var="clients" scope="request" value="${compteMarcheService.test()}"/>

thanks , but i still have the same problem , i get an empty field . — nedal jedidi, Mar 04 '15 at 13:59

If you would like toe xpose classes (beans) to JSP's you could do it as either a Tag library or there is also one more way

<bean    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
   <property name="exposeContextBeansAsAttributes" value="true"/>
</bean>

<bean id="myBean" class="com.x.MyClass"/>

Just have done the same thing using annotations:

@Bean
public ViewResolver tilesViewResolver() {
  final UrlBasedViewResolver = new UrlBasedViewResolver();
  ...
  viewResolver.setExposeContextBeansAsAttributes(true);
  viewResolver.setExposedContextBeanNames("myBean");
  return viewResolver;
}

And in my .jsp:

<c:set var="myBeanData" scope="request" value="${myBean.myMethod()}"/>
<a id="id" href="${myBeanData}">Link</a>
