Re: J2ME or network programming or...what do you recommend?

hiya

My head is spinning just from thinking how much I must learn. My
biggest fear is that by the time I learn most of this stuff, it will
already become obsolete ( I'm talking about XML, DHTML, XHTML, JSP )


More of you guys answer my first three question, more I will be able
to draw some conclusions about how and what :)

1)
a) Would you recommend learning as much different technologies as
possible ( JavaScript, servlets, DHTML, XHTML ... ), or would you
recommend more of specialization ( knowing less technologies, but can
go deeply when trying to understand them ) ?

b) Are you guys more of specialized type or do you know alot of
different technologies ?

c) what technologies do you use on regular basis when programming
apps?


2)
Say you guys want to build Yahoo like chat server-client program. What
technologies ( servlets etc ) would you use on:
a) server side
b) client side



3)
Uh, I have 1000 pages long Java book in pdf format, which includes
chapter on servlets, but no mention of J2SE or J2EE. So will I have to
buy a book about J2EE specifically, even if the book I have already
explains Servlets?


4) do you also recommend learning in addition to java some lover level
language ( like C ), to provide additional functionality ( when
needed ) to java server programs?

So what are the technologies I should learn regardless of the kind

applets AND javascript AND XML and ...)?

How deep do you want to go? Are you doing the entire Web page, or are
you simply supplying data which someone else will extract to the
screen?


Truth be told, I have no idea if doing entire Web page all by myself
is even possible. Only thing I can do is ask all of you guys if that
is even recommendable ( I thought that the more different technologies
you know, less good you are at each of these technologies ) and if
you're able to do entire Web pages by yourself and some time span of
how long would it take for me to become somewhat proficient at this?


Client side:
JSP - well OK, it is on the server, but given to the client.
XHTML
DHTML - for dynamic effects such as mouseover
CSS - for layout, colours, fonts
Javascript - for interactive support
AJAX - not the entire set (though you can), but enough to be able to
communicate in the background.


If I am to do anything at client side then I should learn all of the
above? *faints*



...AND javascript ..
Only relevant if you want the (D)HTML GUI.

So thin-client GUI ( made by servlets ) is not the same as (D)HTML
GUI?


thank you kindly for your input

cheers
