MultipleFileUpload extension discussion

Tuesday 28 March 2006 1:13:19 am

I've used this extension with success on earlier eZ systems, but on my latest install it just won't work. I'm running eZ 3.6.0 on Apache/1.3.33, PHP/4.3.10.

Accessing the select-page works fine, but on the upload-page the java just won't load. I did some testing, and found out that the rewriterules that's distributed with 3.6.0 isn't compatible with the multiplefileupload directory structure:

This is default:
RewriteRule ^/extension/[^/]+/design/[^/]+/(stylesheets|images|javascripts?)/.* - [L]

I added this rule:
RewriteRule ^/extension/[^/]+/design/(stylesheets|images|applets|javascripts?)/.* - [L]

The default rule demands a directory between /design/ and /javascripts, /images etc (e.g. /design/<b>base</b>/applets/), but this isn't the case in the multiplefileupload-extension. It doesn't include the applets-dir either, so I added that too.

Doing this, I can now access the files from my webbrowser (mysite.com/extension/multiplefileupload/design/applets/jupload.jar).

But the Java still won't load. Trying to open the files in Java 2 Platform, I get the following error message: "Failed to load Main-Class manifest attribute from ../jupload.jar".

In the upload window, the following is displayed in the Java console:

java.lang.ClassFormatError: Incompatible magic value 171712813 in class file JUploadPlugin_FolderChooser
	at java.lang.ClassLoader.defineClass1(Native Method)
	at java.lang.ClassLoader.defineClass(Unknown Source)

	at sun.applet.AppletPanel.runLoader(Unknown Source)
	at sun.applet.AppletPanel.run(Unknown Source)
	at java.lang.Thread.run(Unknown Source)

This is repeated for several class files:

java.lang.ClassFormatError: Incompatible magic value 171712813 in class file JUploadPlugin_FiletypeChooser
java.lang.ClassFormatError: Incompatible magic value 171712813 in class file JUploadPlugin_SimpleFileChooser
java.lang.ClassFormatError: Incompatible magic value 171712813 in class file JUploadPlugin_ImagePreview
java.lang.ClassFormatError: Incompatible magic value 171712813 in class file JUpload/startup
java.lang.ClassFormatError: Incompatible magic value 171712813 in class file JUploadPlugin_ProgressMeter

So, I'm pretty stuck here. What can I do to resolve these issues?

I have verified that I have access to the file, so the rewriterules should be working.

I tried to download the newest version of JUpload, but still get the same error..

Do I perhaps need something installed on my server to get this working?

i need a solution to upload lots of photos and directly extract exif/iptc data from the images and store them as attributes of the uploaded objects. would this be possible with your solution. or would this require big changes in the code?
i haven't even installed your extension yet, but will do so soon. looks great!

Hi all,

I have the same problems as Eivind (at least when it comes to this module..). I run ez 3.7.5 and php 4.4.x.

I use this module on a number of sites, and for some reason I get this error on some of them.

I see nobody has posted here for a long time but I'm hoping there is still somebody around who can help.

I have installed the extension but the java applet doesn't display.

I guess that this is because the jar file is being blocked by EZP (I had a similar problem with files types with the sjsd editor extension)

However, I have tried the same solution (added the jar to the .htaccess file) but it still doesn't display the java.

The error trace is below

Can anybody help?

Hi,

I know this extension was published 3 years ago but I'm trying to make it works with ezp 4.0.1.

It stucks on :

Fatal error: Call to a member function instantiate() on a non-object in /var/www/photo.studiotmedia.com/extension/multiplefileupload/modules/multiplefileupload/upload_process.php on line 132

// Create object by user id in the section of the parent object
$contentObject =& $class->instantiate( $userID, $object->attribute( 'section_id' ) );

It's just in case there is still someone who works on it and to add a warning for futur users.

Regards.
