Answer 1

The destination is only a file like in Java.

def f = request.getFile('some_file')

//validate file or do something crazy hehehe

//now transfer file
File fileDest = new File("Path to some destination and file name")
f.transferTo(fileDest)

OR if you want to store it at some path relative to user home:

def homeDir = new File(System.getProperty("user.home")) //user home e.g /home/username for unix
File fileDest = new File(homeDir,"path/to/some_folder")
f.transferTo(fileDest)

UPDATE As per why your getFile is not working, you are not submitting your form:

<g:form action="list" enctype="multipart/form-data" useToken="true">

<span class="button">                   
                    <input type="file" name="filecsv"/>
                    <input type="button" class="upload"
                                        value="Upload"
                                        onclick='location.href = "${createLink(url: [action: 'upload'])}"'/>

            </span>

</g:form>

Should be:

<g:form action="upload" enctype="multipart/form-data" useToken="true">

<span class="button">                   
                    <input type="file" name="filecsv"/>
                    <input type="submit" class="upload" value="upload"/>

            </span>

</g:form>

if you need to use javascript you should submit the form instead of adding a link to another page.
