How to download localy file with Struts 2

Question

I want to download xml file with my struts application. I recup my xml in JAVA (in my action) . When I click to my link, the download window doesn't open . This my code : ACTION :

@Action(value = "download", results = {
            @Result(name = "success", type = "redirectAction", params = {
                    "actionName", "testMM"}),
            @Result(name = "input", location = "testMM.jsp") })
    public String dowload() {
        setFilePath(getSession().get("filePath", String.class));
        setFileName(getSession().get("fileName", String.class));

        try {
            fileInputStream = new FileInputStream("c://mm.xml");



        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return SUCCESS;
    }

/**
     * @return the fileInputStream
     */
    public InputStream getFileInputStream() {
        return fileInputStream;
    }

MY JSP:

<s:url id="fileDownload" namespace="/adminMM" action="download" ></s:url>

When downloading a file with Struts2, you need to use the Stream result type:

@Action(value = "download", 
    results = {
        @Result(name = "success", type = "stream", params = {
                "contentType"        , "text/xml",
                "inputName"          , "fileInputStream",
                "contentDisposition" , "attachment;filename=\"foobar.xml\""
        }),
        @Result(name = "input", location = "testMM.jsp") 
    }
)

Return an ERROR in case of file not found, you are just printing the stacktrace and returning SUCCESS the same;
Correct the typo in the dowload method that must be download.
