Getting an array of an object from a web form using the Spring structure

Question

I have a JSP form web page, this form contains several instances of the same Java object. I use the Java Spring Framework to control the "communication" with the controller and view.

My problem is that I would like to get from the view a simple array containing instances of my objects that are currently on the page (probably changed).

When I want a specific type of element, I usually call it in the declaration of the controller method, however for an array (or any collection) this will not work.

so something like:

@RequestMapping
public String edit(...SomeObject[] objectName, ...){
}

will just return me an error, however I can get an array of String, so this works:

@RequestMapping
public String edit(...String[] objectString, ...){
}

    // do stuff with fooCmd.getMyCollection() 
}
