The Applet seems great and recordes the voice input perfectly.
It fails at uploading tht voice file to the server though.

I read and reread the documentation and installation instructions, and I concluded that the error lies with an exception in the servlet code somewhere.


Using the WAV recorder and the "WAV_JBOSS_JSP" files. But instead of JBOSS, using Weblogic.(Should'nt matter I suppose).
Using a local server with url "localhost:7001"

Here is the Java Console output. It has the output of 2-3 tries of reloading and rerecording.

You use Java Plug-in Version 1.4.1_06. It is not so new. Last version is 1.6. Please update it. If this problem will be again, please contact me.
Thanks.

Seregy, Please can you provide me with the source code of the java servlets where the error is occuring ? The code of the corrosponding php file is available to everyone. .

A big thank you for helping me out over here.

[Sergey]

Please send me source code of applet call. I need to know applet parameters values
Thanks.

[udkl]

For good measure, I included the whole page and highlighted the applet part.

[Sergey]

unfortunately that information you gave me is not enough. Please, send me server console after error was occured. I would like to analize it. Thanks.

[udkl]

The server console does not have any messages. It remains blank.

Once, it did give a " /voicefiles/ not found " kinda error. It dosen't give it now though.
Wish I could peek into the source code that deals only with uploading.....

[Sergey]

Please, put the demo of recording applet on the server which is accessible for me and give me login&password to it.
We will figure out why applet can not upload audio file on the server.

[Joel]

I seem to be getting the same error using the demo applet downloaded from your site:

I'm using the applet embedded in an HTML page. The page it's supposed to be trying to upload to is never touched--no requests for that page appear anywhere in my web server's logs. Here's the applet tag in my page:

We did some modification of applet. Applet file is attached to this post. Unzip it before using. Inform me about result.

[Sergey]

Applet can upload files only on server that it was loaded from. So if you try to upload files on "localhost" you should load applet from web page on "localhost". Maybe you run web page with embeded applet by doubleclicking and web page loads by "file:///..." protocol instead of "http://localhost/.."

[Joel]

No, I am definitely loading the webpage that contains the applet from http://localhost, and trying to upload to http://localhost

[Joel]

Ok, it looks like the behavior did change with the update you provided. I do now see the POST in my server's log files.

The request was still failing because the page which I had set up to handle the upload was in a directory that required authentication. I moved the page for handling the upload to a directory that allows anonymous access, and now it looks like it's working as expected.

Thanks!

[Joel]

Well... it posts to the correct page now, but I'm not getting any POST values, it's completely empty. No file is uploaded, and there are no POST values. I'm using the ASP.NET sample project from one of the other forum posts, and the applet downloaded from this post.
