Question: I am using spring mvc for developing my portlets. Is it mandatory that we have to use spring taglibs in the jsp too? I used and aui tags. Can I map ModelAndView object to aui tags? I need to populate the fields using the model I set from the render method. Or is there any other wrokaround for this? I also have a model bean autowired in my controller. For eg: I should be able to set the **model** in **modelandview** object and retrieve that model in jsp to **populate aui** fields.

Answer: 
I set a bean from the controller and used the bean attribute of aui tags. It worked.`<aui:input bean="${questionnare}" ...`. This works fine for me and if bean has value, it gets prepopulated.

```
class YourModel{
 String someValue;
}

```

In the controller we add to the rendermapping method the parameter `@ModelAttribute("yourModel") YourModel yourModel`

and in the liferay jsp page, just add

```
<aui:input type="text" name="someValue"... bean="${yourModel}"/>

```

this will populate the value if it is present.
i think you can use @modelAttribute annotation, spring will bind the request parameters to model.
