How to pass value from controller to javascript in spring mvc

I am trying to get a variable for a javascript function from an object that sends it to view by the controller.

The object with which I am working is Bpmsn.

Through the controller I injected the object into view.

My method of the controller is:

@RequestMapping(value = "/display")
public ModelAndView index2(@RequestParam int bpmsnId) {
    ModelAndView result;
    Bpmsn bpmsn;

    bpmsn = bpmsnService.findOne(bpmsnId);

    result = new ModelAndView("editor/display");
    result.addObject("bpmsn", bpmsn);

    return result;
}

This method I use to make a display of the object.

In the jsp view I inject the attributes of the object, except the textXML that I will use in a javascript script.

    
: 
    
: 
    
: 
    
: 
    
: 
    
: 

With the textXML attribute I want to create a javascript function to import that xml into a bpmn modeler, but I do not know how to get the textXML attribute of the object injected into the view from the javascript script

I tried to call the attribute as in the view but it does not work
