Software Updates for my program in Java

I'm working on an application in Java for a client, and I'm having some doubts about how to distribute it. I have read about Java Web Start, and have some questions:

• Should it be valid for updating my app if I install it and launch from the start menu?
• Could I run my java开发者_JS百科 application offline?

Do you know another alternative rather than WebStart for deploy and update?

Thanks in advance.

PS: Sorry if is a duplicate post, I've been digging in SO for a couple of days and I haven't found an answer yet.

In answer to your first question, the user will always see that latest version of your application, even if they are using a Start Menu entry. This is stated clearly in the FAQ; see the answer to Q5.

In answer to your second question, yes an application can be run offline, provided that it has already been cached. This is mentioned in the FAQ answer to Q25. For more details, refer to the documentation of the information element of the JNLP file; specifically look for the section on "offline-allowed" and what it means.

I'd recommend that you read the material on Oracle's Java Web Start web page to understand what JWS can (and can't) do.
