Liferay File Upload

Liferay file upload tutorial provides sample code to upload files and how to handle it in MVC Portlet.

Let’s jump into creation of Portlet  to upload a file.

  • view.jsp: view.jsp file contains form that will have file input
    1. <%@ taglib uri="" prefix="portlet" %>
      <%@ taglib uri="" prefix="aui" %>
      <%@ taglib uri="" prefix="liferay-theme" %>
      <%@ taglib uri="" prefix="liferay-ui" %>
      <%@ taglib uri="" prefix="liferay-util" %>
      <%@ taglib uri="" prefix="liferay-portlet" %>
      This is the <b>Fileupload</b> portlet.
      <portlet:actionURL var="uploadFile" name="uploadFileAction">
      <aui:form action="<%=uploadFile %>" method="post" enctype="multipart/form-data">
       <aui:input type="file" name="sampleFile" />
       <button type="submit" class="defaultButton" style="margin-left: 10px;">Upload</button>
  • Action Controller:   In the action method,  use the below line of code to get UploadPortletRequest from actionRequest and use uploadPortletRequest.getFile(“{form-input-name}”) to get the File contents Directly
    •      UploadPortletRequest uploadPortletRequest = PortalUtil.getUploadPortletRequest(actionRequest); 
  • file
    1. public class UploadPortlet extends MVCPortlet {
       public void uploadFileAction(ActionRequest actionRequest,ActionResponse actionResponse){
             UploadPortletRequest uploadPortletRequest = PortalUtil.getUploadPortletRequest(actionRequest); 
             ByteArrayFileInputStream inputStream = null;
              try {
                   File file = uploadPortletRequest.getFile("sampleFile");
                   if (!file.exists()) {
                     System.out.println("Empty File");
                 if ((file != null) && file.exists()) {
                        inputStream = new ByteArrayFileInputStream(file, 1024);
                         byte[] data;
                         try {
                                data = FileUtil.getBytes(inputStream);
                           } catch (IOException e) {
       finally {

Deploy the portlet and access the portlet on page.
