Java Plug-in

[L Goundalkar]

Hi all..
"Java Plug-in software enables enterprise customers to direct applets or JavaBeansTM on their intranet web pages to run using Sun's Java 2 Runtime Environment, Standard Edition (JRE) instead of the web browser's default virtual machine."
I have following doubts..
1. When I am using the jsp :p lgin, does this plug-in download everytime I visit the page?
2. What happen's if I have JRE ( not browser JVM )installed on the client system which is of lower version.
3. What happens if it is of higer version.
Thanks a lot for the time.

It normally downloads only one time, the first time the client goes to the page that requests it.

After that it is stored on the client's computer and is dormant until the client goes to the page that requires at which time it loads and begins to run automatically with no interaction from the client.

2. What happen's if I have JRE ( not browser JVM )installed on the client system which is of lower version.

It works with the browser's JVM, not the JVM/JRE installed separately.

3. What happens if it is of higer version.
Depends on the html/jsp page that calls for the plug-in. It is configurable. If it is lower, it may or may not run without downloading the specific plug-in depending on what you have required. If it is higher, it will request the client to download the required plug-in.

So you mean to say,
When I use jsp lugin tag, the first time it compulsorily download the plug-in and install it on the client.
Then onwards it will check for the client JRE and if it is of lower version it will download and install the newer one on the client.
So in any of the cases it will not run in Browsers JVM. Right??
Thanks for the time.
