Upload File Portlet

[Concetta Carone, geändert vor 16 Jahren.]

Hi,
I'm using Lifaray 4.3.6 on server Tomcat.

I have a problem with portlet that has to allow the user to upload a file and
store it into a database.
I have tried throughout the forum but have not found anything that can help
me...It is really REALLY so much that I am trying to find a way!!!

I have deployed sample-struts-liferay-portlet-4.3.6.1.war and tried to upload
file. I got "Upload Success" message.
But I could not find where the file locates, I checked the code, and could
not figure out where the file is stored!! Can I modify the code to specify a
location for the file on disk?

Is there anyone who can help?

I saw that we have so many this type of problem, so, for all those who like me
have this ugly problem:
there is someone who can definitely provide a complete code?
He would be very kind!!!
Thanks in advance
C.C.

Hi,

Is there a solution for portlet upload withouth struts?

I must integrate portlet upload in my portlet application (Sibecs-Liferay) that consists of portlets jsp-existing, ie I must pass it the APPLICATION SCOPE and save uploaded files in my database, and then, being fasting struts, I noticed that I would not know how to combine the two things ... indeed, for what I need, is not the right solution.

To have a portlet upload without passing by struts, the only system seems to use libraries FileUpload Apache Commons.

Carryover here:

• upload.jsp

<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>
<portlet:defineObjects/>
<script language="javascript">
function submitForm (form) {
form.submit();
return true;
}
</script>
<form action="<portlet:actionURL/>" method="POST" enctype="multipart/form-data">
<h3>Upload image form </h3>
<table>
<tr>
<td>Image file</td>
<td><input type="file" name="imageFile"></td>
</tr>
<tr>
<td><input type="submit" name="submit" Value="Submit"></td>
<td><input type="reset" name="Cancel" title="Cancel"></td>
</tr>
</table>
</form>

• FileUploadPortlet.java

import java.io.*;
import java.sql.*;
import java.util.Vector;
import javax.portlet.*;

import javax.servlet.http.*;

import org.apache.commons.fileupload.portlet.*;
import org.apache.commons.fileupload.servlet.*;
import org.apache.commons.fileupload.util.*;
public class FileUploadPortlet extends GenericPortlet {
private String error;
public void doView(RenderRequest req, RenderResponse res)
throws IOException, PortletException
{
WindowState state = req.getWindowState();
res.setContentType("text/html");
PortletSession session = req.getPortletSession(true);
PortletContext context = getPortletContext();
PortletRequestDispatcher rd;
rd = context.getRequestDispatcher("/WEB-INF/jsp/upload.jsp");
rd.include(req, res);

}
public void processAction(ActionRequest req, ActionResponse res)
throws IOException, PortletException
{
PortletSession session = req.getPortletSession(true);
DiskFileItemFactory diskFileItemFactory = new DiskFileItemFactory();
PortletFileUpload portletFileUpload = new PortletFileUpload(diskFileItemFactory);
try {

while (portletFileUpload.parseRequest(req).iterator().hasNext()) {
FileItem fileItem = (FileItem) portletFileUpload.parseRequest(req).iterator().next();
byte[] data = fileItem.get();
session.setAttribute("photo",data,PortletSession.APPLICATION_SCOPE);

}
}
catch (FileUploadException e) {
error = e.getMessage();
System.out.println("[ERRORE]: " + error);
}
}
}

But hot depoly fails!! Nor with the 4.3.4 or 4.3.6!!

make sure you configured your xml files correctly:

Thanks for your answer.
Until the inclusion of this code in my application I have no problems!

My file liferay-plugin-package.xml is:

<?xml version="1.0"?>
<!DOCTYPE plugin-package PUBLIC "-//Liferay//DTD Plugin Package 4.3.0//EN" "http://www.liferay.com/dtd/liferay-plugin-package_4_3_0.dtd">

How can I configure this?
What should I put in module-id?

[Alex Kudinov, geändert vor 16 Jahren.]

module-id should be in format

<module-id><company>/<whatever-your-package-is>/<LR-version>/war</module-id>

Well, the above portion of the package description will only run on Liferay version 4.3.4. If you want it to run on all 4.3 version, make the version specification "4.3.*". I believe there's also a "+" modifier, but you'll have to confirm that.

I usually just edit it to be whatever major/minor version I'm on with a star modifier.

As for dealing with plugins, your best bet is to always look at a working plugin for format/content of the liferay specific files.
