Is Java Web Start applicable for this?

I need to create a new feature on my website. It will be some kind of sound recorder: a user logs in, records a new message using this feature and his microphone. His record is temporary cached on the client, so the user can listen to it before sending somewhere and make necessary corrections.

When the user clicks "Save", his record is saved on the server, and then the user has the ability just to send a link to his friends, so that they could listen to his record.

Is Java Web Start applicable here? Or applets are enough? Or this feature is not the best application for Java Technology at all?

It's certainly possible to do this in Java - the required APIs (in the javax.sound.sampled package) have been part of the JRE for years. I'm not sure how well it's possible to control the interaction with the host operating system, but if you search for "java sound record" you'll find plenty of descriptions from people who've done it.

If you use an applet, it will need to be signed in order to access a client-side resource like a microphone.

Yes, Java can do this. You can also check out Java Media Framework that has rich media capabilities. (

I feel Java Web Start gives you more freedom compared to applet and more importantly execution is independent of client browser. If your java web start application is digitally signed users can trust.

Thanks a lot for your replies.

By the way, can a Java Web Start application be embedded directly into an HTML page, like applet? I mean, just not to open it in a separate window. I guess, it can, right?

You can put the link into your web page, but clicking on the link causes the program to be downloaded to the client. The program doesn't run inside the browser, if that was your question.

I agree. Here's the link:
