Using SpEL and eval to call a controller method

[ufasoli]

Hi,
I was wondering if it was possible to call a controller method using the <s:eval> tag from a JSP page, a bit like the way it's done in JSF.

@Controller(value="planesController")
@RequestMapping({"/planes"})
public class PlanesController {

	@Autowired
	private PlanesDAO planesDAO;
	
	

	public List<Plane> allPlanes(){
		
		return planesDAO.getAll();
	}

<sf:form>
<s:eval expression="planesController.allPlanes()" var="planes" />

<sf:checkboxes items="${planes}" path="planes"  id="avions"/>
	     
</sf:form>

I keep getting the exception :

org.springframework.expression.spel.SpelEvaluationException: EL1007E:(pos 0): Field or property 'planesController' cannot be found on null

I know I can use model.addAttribute but I call this method from several JSP pages and I thought one of the of the <s:eval> tag was to allow access to beans from views.

I'm using Spring 3.0.5


Thanks in Advance

You have to prefix the bean name with the character @

This
<s:eval expression="@planesController.allPlanes()" var="planes" />
should do the job.

You can add parameters too. Something like this should work
<s:eval expression='@planesController.allPlanes(true, "aParameter", 10)' var="planes" />

You find more information in the documentation: http://static.springsource.org/sprin....html#d0e12033
