Uploading files with Liferay

This is a short tutorial for those of you who want to upload a file using Liferay portlets. First you need to give your form in your JSP the correct encoding type:

<form name="<portlet:namespace/>fm" method="post" enctype="multipart/form-data" action="<portlet:actionURL />">

This makes sure that the data you upload is really uploaded. Next you should add the upload button like this :

<input type="file" name="<portlet:namespace/>yourfile" id="<portlet:namespace/>yourfile" />

That´s all in the JSP. If you now add the following in your processAction method, you have access to your uploaded file:

public void processAction(ActionRequest request, ActionResponse response)throws PortletException, IOException {

UploadPortletRequest uploadRequest = PortalUtil.getUploadPortletRequest(request);

String sourceFileName = uploadRequest.getFileName("yourfile");

File file = uploadRequest.getFile("yourfile");
