  1. PONo file being uploaded in Flex
    text
    copied!<p>I am trying to upload a single text file that is 1kb to the server. For whatever reason the data that I receive does not contain the file info. So FileItem.Write(file) does not work. Since FileItem says the size is 0.</p> <p>I don't think this is a connection issue because I managed to receive the URLVariables. The only thing that doesn't come through is the actual file.</p> <p>I followed the adobe flex guide, but it still doesn't work. (<a href="http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_7.html" rel="nofollow">http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_7.html</a>)</p> <p>No errors get thrown and a event complete gets triggered.</p> <p>Any suggestions?</p> <p>flex 3.2 sdk Jboss server java doPost</p> <p>EDIT: Added source code</p> <p>CertificateUploadServlet.java</p> <pre><code>import java.io.BufferedWriter; import java.io.File; import java.io.FileWriter; import java.io.IOException; import java.io.PrintWriter; import java.util.List; import java.util.ListIterator; import javax.servlet.ServletConfig; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.commons.fileupload.FileItem; import org.apache.commons.fileupload.FileUploadException; import org.apache.commons.fileupload.disk.DiskFileItemFactory; import org.apache.commons.fileupload.servlet.ServletFileUpload; public class CertificateUploadServlet extends HttpServlet { public void init(ServletConfig config) throws ServletException { super.init(config); } public void doPost(HttpServletRequest request, HttpServletResponse response) { File disk = null; FileItem item = null; DiskFileItemFactory factory = new DiskFileItemFactory(); ListIterator iterator = null; List items = null; Servlet FileUpload upload = new ServletFileUpload(factory); try { items = upload.parseRequest(request); }catch (FileUploadException e1) { // Oh Noes! } iterator = items.listIterator(); while(iterator.hasNext()) { item = (FileItem) iterator.next(); if(item.isFormField()) { }else { try { PrintWriter out1 = new PrintWriter(new BufferedWriter(new FileWriter("C:/Test/processUploadedFile2.txt",true))); out1.println("item.getContentType():\t\t "+item.getContentType()); out1.println("item.getName:\t\t "+ item.getName()); out1.println("item.getSize:\t\t" + item.getSize()); out1.println("item.getString:\t\t" + item.getString()); out1.println("item.getFieldName:\t\t"+item.getFieldName()); out1.println("item.isInMemory:\t\t" + item.isInMemory()); out1.println("item.toString():\t\t" + item.toString()); out1.close(); } catch(IOException e) { // oh Noes~ } } } } </code></pre> <p>}</p> <p>dataTest.mxml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="horizontal" creationComplete="init()"&gt; &lt;mx:Script&gt; &lt;![CDATA[ import flash.netFileReference; import mx.controls.Alert; private var fileRef:FileReference = new FileReference(); private function init():void { fileRef.addEventListener(Event.SELECT, selectHandler); fileRef.addEventListener(Event.COMPLETE, completeHandler); } private function selectHandler(event:Event):void { Alert.show("Selected..."); var request:URLRequest= new URLRequest("https://localhost/scm/uploadServlet"); fileRef.upload(request); } private function completeHandler(event:Event):void { Alert.show("File got uploaded"); } ]]&gt; &lt;/mx:Script&gt; &lt;mx:Button id="mBrowseButton" label="browse..." click="fileRef.browse()" /&gt; &lt;/mx:Application&gt; </code></pre> <p>item.getName: returns the correct file name that I want to upload</p> <p>but item.getSize always returns 0 and thus when I try to write the file on the server it is always empty.</p> <p>More info:</p> <p>I am able to add variables to URLVariables class and retrieve it in the java class.
