FileUpload NullPointerException Problem

[ume]

How do you do.

I am a Japanese. Name is Ume.
I am sorry that I am not good at English.
This mail post first time at English.

I met the following exception using commons-FileUpload.
(I found same Problem ,
http://www.mail-archive.com/[EMAIL PROTECTED]/msg03431.html)

I found the solution method.

Problem

java.lang.NullPointerException
        at 
org.apache.commons.fileupload.FileUploadBase.createItem(FileUploadBase.java:507)
        at 
org.apache.commons.fileupload.FileUploadBase.parseRequest(FileUploadBase.java:390)
        at HogeSrv.doPost(HogeSrv.java:65)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)
...

HogeSrv.java
63:     FileUpload fu = new FileUpload();
64:     fu.setSizeMax(1000000);
65:     List fileItems = fu.parseRequest(req);
---

It was OK, when I add 
fu.setFileItemFactory(new DefaultFileItemFactory());
before 65 line.

I see source

FileUpload.java 1.24

    /**
     * Constructs an instance of this class which uses the default factory to
     * create <code>FileItem</code> instances.
     *
     * @see #FileUpload(FileItemFactory)
     */
    public FileUpload()
    {
        super();
    }

and 

DiskFileUpload.java 1.4
    /**
     * Constructs an instance of this class which uses the default factory to
     * create <code>FileItem</code> instances.
     *
     * @see #DiskFileUpload(DefaultFileItemFactory fileItemFactory)
     */
    public DiskFileUpload()
    {
        super();
        this.fileItemFactory = new DefaultFileItemFactory();
    }

therefore

FileUpload.java

    /**
     * Constructs an instance of this class which uses the default factory to
     * create <code>FileItem</code> instances.
     *
     * @see #FileUpload(FileItemFactory)
     */
    public FileUpload()
    {
        super();
                // add line
        this.fileItemFactory = new DefaultFileItemFactory();
    }

It seems OK, this Source.
Is it solution method?
