simplest java code to upload files in LIFERAY portal

1 in the jsp make a form to handle the upload

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<%@ page import="java.util.List"%>

<%@ page import="java.util.ArrayList"%>

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>

<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet"%>

<form action="<portlet:actionURL/>" method="post" name="form1" ID="form1" enctype="multipart/form-data">

</form>

2- in the process action method in the portlet class

@Override

public void processAction(ActionRequest req, ActionResponse res)

throws PortletException, IOException {

//getting the file

UploadPortletRequest ureq=PortalUtil.getUploadPortletRequest(req);

File file=(File) ureq.getFile("file");

copy(file,new File("c:/im/"+file.getName()));

System.out.println("file name is ===> "+file.getName());

// the following line to get the normal paramters from the multipart encoded form
String name = ParamUtil.getString(ureq, "name");

}

3- helper method for copying file to another

private void copy(File src, File dst) throws IOException {

InputStream in = new FileInputStream(src);

OutputStream out = new FileOutputStream(dst);

// Transfer bytes from in to out

byte[] buf = new byte[1024];

int len;

while ((len = in.read(buf)) > 0) {

out.write(buf, 0, len);

}

in.close();

out.close();

}
