JSP vs.HTML

(1)JSP simply puts Java inside HTML pages.

 You can take any existing HTML page and change its extension to ".jsp" instead of ".html".

Now load the new file, with the ".jsp" extension, in your browser. You will see the same output, but it will take longer! But only the first time. If you reload it again, it will load normally. What is happening behind the scenes is that your JSP is being turned into a Java file, compiled and loaded.
This compilation only happens once, so after the first load, the file doesn't take long to load anymore. (But everytime you change the JSP file, it will be re-compiled again.)

 (2)can enclose Java expressions and java code (called a scriplets), which are evaluated at run time. use <%= and %>

 It is true that JSPs are primarily HTML with embedded Java code. However, they have many advantages, such as requiring less (typically none) configuration, and being easy to modify and deploy. Therefore they can lend themselves to other usages, such as writing simple and straightforward controllers.

 JSP's eventually are turned into servlets, and though JSPs are much simpler than servlets, for some cases servlets are still useful.

Eclipse: Install Plug Ins

If one can connect to internet, it is easy to install Eclipse Plug Ins.
Go to "Help" --> "Install New Software" --> enter url in "Work With"

But what to do when it is not possible to connect to Internet from Eclipse?

two ways:
(1) find the plug in Zip, download it to local, then use
"Help" --> "Install New Software" --> click on "Add" beside "Work With",
click on "Archive" , select the zip file from your local disk, then Open it.


(2) find the internet proxy which can be used to access internet.
Or use Fiddler (IE browser web debugging tool) to find the proxy Fiddler is using and configure in Eclipse to use it to access the plug in web sites.
