how does Java code run in client browser's JRE?

Hello ranchers,
Dont quite know which forum this question fits into.....

Recently have been moved into a team that is developing rich client applications.

My questions are ::

1 >Browser is supposed to execute some java code on client side

so how does the client browser receive the java class files from server ?

I am only aware of the html that is simply rendered in case of typical j2ee applications

In such a case is it necessary to have signed jars ?

Thanks,
anagha

There will be a tag in your HTML that tells it which jar file to download. It's a while since I worked with applets so I'm not absolutely sure of it's anme and format.

Depends what you want the applet to do. If you need to access the local computer's file system then it will need to be signed.

Doesn't your new team have a leader who can explain all this to you ?
