Manoj,
require is for Clojure libraries only.
You probably want import:
http://clojure.org/api#toc297
but note that you don't need to *load* Java libraries per se, so long
as they're in the classpath: import simply makes the names available
in the current namespace.

Hi,
I am basically a .Net programmer, trying out Clojure on both java

Hi
Instead of:
(conj (drop-last 1 [1 2 3]) 4)
You could use into []:
(conj (into [] (drop-last 1 [1 2 3])) 4)
[1 2 4]

Hi Emeka,
I'm glad you're interested in my library. You're welcome to use it,
and I'd be happy to answer any questions you have. I should warn you
that it's still very rough, and I'm changing things around on a
regular basis. I can't guarantee that any program you write against

I've noticed that changing namespace with ns and then doing a def
doesn't behave the same inside a do form:
Without the do form it works as expected:
user=> (ns a) (def foo "foo")
nil
a=> #'a/foo
a=>
If the same code is executed inside a do form the var is defined in
the original namespace. I
Hrm, I've never found it all that hard to type "ant" when I want my

I will admit, when I first used ant, I was scared to death because of

Using conj and pop on vectors for stack operations should work just
fine. Don't use subvec though; nest
the sequence functions operate on sequences. if you pass in something
that is not a sequence, like a vector, they call seq on it internally.
so what you get back from filter or map is a sequence. conj has
consistent behavior across types, you just get a different type out of
map/filter/etc then wh
I've been trying to implement stacks using vectors in Clojure. In case
you wonder why, it's because I need stacks with a fast item count
operation. While experimenting I discovered some vector properties which
were unexpected.
conj adds at the end of the vector as expected:

Yes, you are right! WinCommand is the repl!
I think that the problem that you have is with java location.
Did you set JAVA_HOME in wincommand.ini? this variable will replace
JAVA_HOME in the path of clojure application config (last two lines of
the [applications] area).

Hi :
I would like to simulate a simple database with the STM of clojure.
The rules are
1. There can be many rooms, and each room has its own attirbute
2. One room contains many people, and each person has its own
attribute
3. rooms can be created, and deleted, and people can be added into or

Another Java STM is multiverse: http://code.google.com/p/multiverse/ -
the focus here is on performance. Multiverse is based on MVCC, like
the Clojure STM.
