about freemarker

[hdalang]

I'm begginer in web developing, I have started to learn freemarker template, but I'm not sure about .ftl how can I use it in web user interface?
Cause I've done some tutorial using eclipse. and all result are showing in console, but I didn't try it with web browser, to see it's features.
What I understand until now it's used to create html, xml, …etc. but I'm not sure how developers are using it in web development. can someone explain how developers using it in web development?

Also try to create a simple webscript in alfresco for that you need to create an ftl file.

Until now I didn't get further in developing it with alfresco share, cause I need some time before starting with alfresco share, that's why my question was how does it work ?
I mean if I viewed some output html file, then how to let this html execute the java which has loaded the .ftl file, to return it back to html?
My problem is in executing the java from html(web browser, which will return the output. how can it be done?
