Hello,
I tried to learn more about JAVA WebStart, and have a question. I
successfully created a HelloWorld application using Eclipse 3.0.
I also got the JAVA WebStart running for my application. If I install now
this application via WebStart (offline allowed) on another machine (just JRE
installed) I can run it successfully.
Now I want to find the JAR file of my application on that machine. If I do a
local search for that JAR file there is no result. It seems this JAR file
does not exist on that machine, even I can execute my application using
WebStart (online AND offline).
So where is the JAR file located? Is it compressed and in hidden in another
file / another filetype?
Thanks for any help!

Hi,
Java Web Start is a technology which enable you the following features:
- web based client application install
- automatic version checks and updates for the application
- a sandbox to run your application within
If you want to learn about more for this topic you should start on the java
web start page: http://java.sun.com/products/javawebstart/. The white paper
give you a lot of information about this technology.
I think that files in the cache with RT... prefixes contains some computed
codes which helps jws to decide if the cached version is up-to-date (you can
see its content, it is not a jar but a plain text file). Typically an
end-user who uses your application do need to know nothing about these files
(they are always cached within the ...\cache\javaws directory afaik).
HTH,
