setDefaultCellBorder cannot find method in itext 2.1.0

[purnama]

why setDefaultCellBorder method cannot find in itext 2.1.0 ?
before i use itext 1.4 and running well. And when i use itext 2.1.0,
java cannot find setDefaultCellBorder method :
my source :table.setDefaultCellBorder(0);
so what should i do ? how to change this source ?

If your code uses a method that is not defined in a class. The class coming from a jar file.
Either get a new jar file with the class having the desired method
Or read the API doc for the class and see if there are other methods that will do what you want.

i use 2 itext library jar in my application. i text 2.1.0 and itext 1.4.
is it good or bad ?

s it good or bad ?

I don't use either so I have no idea.

Its bad to use multiple jars of the same product in any application as this may cause issues with classes getting used that weren't expected(Older ones getting built instead of the newer ones, or vice-versa).
