For example the two dimensional array "test" has this data:

Col1 Col2 Col3
Row1 a b c
Row2 d e f

and JSP will read this from request variable and display it.

These values (a,d) are displayed as hyper links to a page testpage.jsp.

...
'Row1, Col1'
<a href='thetarget.jsp?Col2=b&Col3=c'>a</a>
....
'Row2, Col1'
<a href='thetarget.jsp?Col2=e&Col3=f'>d</a>

What I need to do is, when user clicks a , I need to set b and c in a
variable array

'Variable array'? Why not simply include it as the
parameters of a (plain old) hyperlink?

2. Do I need Javascript ? or it can be done in Java? I prefer to have all
the code in Java.

Do it in HTML. Use whatever (server) side language you
like to generate the HTML, but leave JS out of it - it is an
unnecessary complication.

3. How is it possible to access and change a request variable from
JavaScript ?

Between pages? See above.
'In-place' in a single page - that would
require JavaScript.
