File upload in specific folder

[Rakesh Goswami, modificado 12 Anos atrás.]

I am using liferay 6.0.5. I am uploading file using following code.

UploadPortletRequest uploadRequest = PortalUtil.getUploadPortletRequest(actionRequest);
 String submissionFileName = uploadRequest.getFileName("file");
    File submissionFile = uploadRequest.getFile("file");

this works fine and upload file in tomcat's temp directory with some different file name. What I want is.."There is one folder docs in my project directory. I want uploaded file in this directory with same name". How to do this in liferay.?

[Jitendra Rajput, modificado 12 Anos atrás.]

i guess thats the manual stuff ..You need to write your own code ..once file is available inside temp folder ..you can rename it to original name ..once it is rename you can store this to any specific folder/document library.

I explain full flow. I am creating auto generated doc file with some data from UI input replacing the bookmark in my template file. Then I am putting that file in doc library. Now On my custom portlet I am providing link to view/download doc file that is created. And on that same page one file upload is available. Now what I am trying to do is replace the old doc library file with the uploaded file in doc library. and in tomcat temp directory on every file upload,uploaded document is getting different names..how to identify which one is the last one. Please suggest any alternative way to achieve what I am trying to do..Thank you.

you can use below code to rename your uploded fie to original name.

UploadPortletRequest uploadRequest = PortalUtil.getUploadPortletRequest(actionRequest);
File  tempFile = uploadRequest.getFile("file");

         File destination = null;
        String path = tempFile .getPath();
        path = path.substring(0, path.lastIndexOf(StringPool.BACK_SLASH) + 1);
        String fileNm = uploadRequest.getFileName("file");
        if (Validator.isNotNull(fileNm))
        {

            path = path.concat(fileNm);
            destination = new File(path);
            FileUtil.copyFile(tempFile , destination);
            FileUtil.delete(tempFile );
        }

Thank you for you quick response..
I have tried code given on this forum
http://www.liferay.com/community/forums/-/message_boards/message/11489818?_19_redirect=http%3A%2F%2Fwww.liferay.com%2Fcommunity%2Fforums%2F-%2Fmessage_boards%2Fsearch%3F_19_keywords%3Dfile%2Bupload%26_19_searchCategoryId%3D0%26_19_breadcrumbsCategoryId%3D0%26_19_redirect%3Dhttp%253A%252F%252Fwww.liferay.com%252Fcommunity%252Fforums%252F-%252Fmessage_boards%252Fmessage%252F13060502
and it stores document on specific folder with same name. That's what I was trying to do..Thanks again.

Hai..All..how to use attribute of below for uplaoding file..<aui:form tag...

I dont find this attribute..in aui.tld file...

enctype="multipart/form-data"

[Manish Yadav, modificado 11 Anos atrás.]

in place of alloy UI you can use
<form name="UploadForm" action="<portlet:actionURL/>" enctype="multipart/form-data" method="POST">
<input type="file" name="fileName" size="50"><br>
</form>

[sheela mk, modificado 11 Anos atrás.]

Hai..My complete..Project is on AUI tags..I cant change..it..for normal HTML tags..Pls Let me know any other Solution...

if you find..

if you find..

then you can use
<aui:form action="<%= editArticleActionURL %>" enctype="multipart/form-data" method="post" name="fm1">
</aui:form>

it will work

But its not working..if i put file uploading field with other fields,..other fields values only..will not come..in the list..

On removing..File Upload..List values gets populated..from jsp.

you can use UploadPortletRequest object for uploading file with other attribute in form

process action method

public void requestMeeting(ActionRequest actionRequest,
		ActionResponse actionResponse) throws IOException, PortletException, SystemException, PortalException {
	

	PortletURL portletURL = getPortletURL(actionRequest);
	
//	
	try {	
		
		UploadPortletRequest uploadRequest = PortalUtil.getUploadPortletRequest(actionRequest);
		ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);
		ServiceContext serviceContext = ServiceContextFactory.getInstance(DLFileEntry.class.getName(), actionRequest);
		
		
		String title = Integer.toString(ParamUtil.getInteger(uploadRequest, "title"));
		String email = ParamUtil.getString(uploadRequest, "email");
		String name = ParamUtil.getString(uploadRequest, "name");
		String sourceFileName = uploadRequest.getFileName("file");
		File file = uploadRequest.getFile("file");	


//then you can wtrite your logic here

jsp you can use normal html or aui whichever you feel comfortable

I used only Jquery Ajax .I haven't use AUI for ajax.
below is jquery Ajax for submitting form

view.jsp file

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>

function ajaxcall()
{   
var  empname= document.SubmitForm.empname.value;
var employeeId=document.SubmitForm.employeeId.value;
var ajaxdata=name+":"+employeeId;

    jQuery.ajax({
                type     : "POST",
                url      : "<%=ajaxUrl%>",
                data     : "ajaxdata=" +ajaxdata,
                success  : function(data){
               
                //write your logic here
               
                }
                   
                },
                async    :    false,
                });

   
}

<form name="SubmitForm" id="SubmitForm" action='#' method="post"  >
<input type="text" size="30" id="empname" name="empname">

Hi! I'm posting you a full working example

You can specify the upload folder in the portlet.xml

	<init-param>
			<name>uploadFolder</name>
			<value>/home/laura/uploads/</value>
		</init-param>

The File is uploaded to the folder identified by the "uploadFolder" portlet initialization parameter.

view.jsp:

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<%@ taglib uri="http://liferay.com/tld/aui" prefix="aui" %>
<%@ page import="javax.portlet.PortletPreferences" %>
<portlet:defineobjects />

You can upload a new clinical case clicking on "Upload case". 
<br>

<portlet:renderurl var="editCaseURL">
<portlet:param name="jspPage" value="/edit.jsp" />
</portlet:renderurl>

<aui:button onClick="<%=editCaseURL%>" value="Upload case" />

edit.jsp:

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet"%>
<%@ taglib uri="http://liferay.com/tld/aui" prefix="aui"%>
<%@ taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui"%>
<%@ page import="com.liferay.portal.kernel.util.ParamUtil"%>
<%@ page import="com.liferay.portal.kernel.util.Validator"%>
<%@ page import="javax.portlet.PortletPreferences"%>

<portlet:defineobjects />
&lt;%  //... %&gt;
<liferay-ui:success key="success" message=" YEAH. Case uploaded successfully!" />
<liferay-ui:error key="error" message="Sorry, an error prevented the upload. Please try again." />

<portlet:actionurl var="editCaseURL" name="uploadCase">
	<portlet:param name="jspPage" value="/edit.jsp" />
</portlet:actionurl>

<aui:form action="<%= editCaseURL %>" enctype="multipart/form-data" method="post">
<aui:input type="file" name="fileName" size="75" />


<aui:button type="submit" value="Save" />
</aui:form>

And this is the portlet class :

package it.laura.test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

import javax.portlet.ActionRequest;

import com.liferay.portal.kernel.util.FileUtil;

import java.io.File;
import com.liferay.portal.util.PortalUtil;
import com.liferay.util.bridges.mvc.MVCPortlet;


import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;


public class UploadCase extends MVCPortlet {


	protected String realPath=null;
	private static Log logger = LogFactory.getLog(UploadCase.class);

	public void uploadCase(ActionRequest actionRequest, ActionResponse actionRresponse) throws PortletException, IOException
	{  
		String folder=getInitParameter("uploadFolder");
		realPath = getPortletContext().getRealPath("/");
		byte[] bytes = null;
		PortletContext portletContext = actionRequest.getPortletSession().getPortletContext();
		logger.info("RealPath"+realPath+" UploadFolder :"+folder);
		try{ 
			logger.info(" Into the Try");
		    UploadPortletRequest uploadRequest = PortalUtil.getUploadPortletRequest(actionRequest);

		     String sourceFileName =uploadRequest.getFileName("fileName");
		
	File file = uploadRequest.getFile("fileName");

			try {   	
				bytes = FileUtil.getBytes(file);
			} catch (IOException e2) {			
				e2.printStackTrace();
			}
			File newFile=null;
			
			if ((bytes != null) && (bytes.length > 0)) {
			
			try {
			newFile = new File(folder+sourceFileName);
			FileInputStream fileInputStream = new FileInputStream(file);
			FileOutputStream fileOutputStream = new FileOutputStream(newFile);			
			fileInputStream.read(bytes);				
			fileOutputStream.write(bytes, 0, bytes.length);					
			fileOutputStream.close();
			fileInputStream.close();
			SessionMessages.add(actionRequest, "success");
		} 
			catch (FileNotFoundException e) {
				System.out.println("File Not Found.");				
				e.printStackTrace();
				SessionMessages.add(actionRequest, "error");
			}
			catch (IOException e1){
				System.out.println("Error Reading The File.");
				e1.printStackTrace();
				SessionMessages.add(actionRequest, "error");
			}
		}
	        
} catch (Exception e) {
		System.out.println("Exception::::"+e.getMessage());
		SessionMessages.add(actionRequest, "error");
	}
}
 

Enjoy it! :-)
