Apache Commons FileUpload getString() method - Java

Apache Commons FileUpload getString() method - Java

My FileUpload Servlet code:
public void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
NewsItems ni = new NewsItems();
if (isMultipart) {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
try {
List items = upload.parseRequest(request);
Iterator iterator = items.iterator();
String [] myValues = new String[6];
while (iterator.hasNext()) {
FileItem item = (FileItem) iterator.next();
int i = 0;
if (item.isFormField()) {
myValues[i] = item.getString();
System.out.println("my vals: "+myValues[i]); //PRINTS
THE VALUES
}
i++;
}
String newsContent = myValues[2]; //PRINTS NULL
System.out.println(newsContent);
} catch (FileUploadException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Here I'm trying to assign getString() values to a String Array. In above
the code , System.out.println which is inside the While Loop prints the
values but the System.out.println outside prints NULL. Any reasons for
this and can someone please provide me a solution. Thanks for the help.
