Upload portlet

[audran12]

Hello,
I try to create an upload portlet.
I have downloaded Jboss portal sources but there is no simple portlet like I need.
So, if you can help me with a simple java code to upload a file.

Thank you.

Hi Audran,

here you can see an example to implement an upload portlet using PortletFileUpload class:

http://commons.apache.org/fileupload/apidocs/org/apache/commons/fileupload/portlet/PortletFileUpload.html

You can follow the example below ;)

Hope this helps.

FileUploadPortlet.java:

package com.yourcompany.yourapp.view.portlet;

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Iterator;
import java.util.List;

import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.PortletRequestDispatcher;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;


import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.portlet.PortletFileUpload;

public class FileUploadPortlet extends GenericPortlet {

 protected void doEdit(RenderRequest renderRequest,
 RenderResponse renderResponse) throws PortletException, IOException {
 renderResponse.setContentType("text/html");
 PortletRequestDispatcher requestDispacther = getPortletContext()
 .getRequestDispatcher("/yourFileUpload.jsp");
 requestDispacther.include(renderRequest, renderResponse);
 }

 public void processAction(ActionRequest actionRequest,
 ActionResponse actionResponse) throws PortletException, IOException {
 DiskFileItemFactory diskFileItemFactory = new DiskFileItemFactory();
 PortletFileUpload portletFileUpload = new PortletFileUpload(
 diskFileItemFactory);
 try {
 List fileItemList = portletFileUpload.parseRequest(actionRequest);
 Iterator fileIt = fileItemList.iterator();
 while (fileIt.hasNext()) {
 FileItem fileItem = (FileItem) fileIt.next();
 InputStream is = fileItem.getInputStream();
 String filePath = "yourFilePath";
 FileOutputStream fis = new FileOutputStream(filePath+fileItem.getName());
 int c;
 while((c = is.read()) != -1) {
 fis.write(c);
 }
 }
 } catch (FileUploadException e) {
 e.printStackTrace(System.out);
 }
 }
}

yourFileUpload.jsp:

<%@ taglib uri='http://java.sun.com/portlet' prefix='portlet'%>
<portlet:defineObjects/>
<form action="<portlet:actionURL/>" method="POST" enctype="multipart/form-data">
Upload your file
 <table>
 <tr>
 <td>Your file</td>
 <td><input type="file" name="yourFile"></td>
 </tr>
 <tr>
 <td><input type="submit" name="submit" Value="Submit"></td>
 <td><input type="reset" name="reset" title="Reset"></td>
 </tr>
 </table>
</form>

portlet.xml:
