Sorry for asking this question but i searched all java realted question but i got more confused. I am still not clear what should i start with

1)My main is build website in Java because someone told me that there are some machine learning or AI libraries available in java which i can use in java. so i decided to use that as it can reduce my work.

Now i don't know java at all some people say following are used to build websites like

1)Servelts alone can build webiste
2)JSP alone can also build webiste
3)Struts
4)Spring with Hibernate
5)SEAM
6)JEE also for webistes

Now guys i am confused where should i start from. Where does core JAVA fits in here.

i was thinking of perhaps learning python as i know i have to learn Python only not its variations

SO please guide me one thing which can solve my basic purpose of using ready made libraries of AI

If i can do that with JSP then i will start with that. But i need to learn all of them then its better if can start learning python.

I have 5 months to finish webiste.

I really don't know why there are many braches of java for doing one thing

Please help me.
