I'm working with leiningen for the first time and trying to use
clojure.java.jdbc. All the docs I see use 'sql' before the jdbc
commands. How do I set up the sql symbol. Nothing I've tried seems to
work.

I think I understand what you're looking for. I have the same
concern.
There very best Java book I have found is "The Java Developer's
Almanac"
by Patrick Chan. Volume 2 covers Swing and Volume 1 covers
everything
else. No nonsense, just answers with great examples.

Can anyone help me with this? I get the following error:

Line 22 is the ns statement - no other error line in my program is
listed. I've used dosync many times. Every

If you are looking for a very good editor for Clojure try Bluefish.
It's been around for ever, is very stable, and does everything you
would want an editor to do. And it now works with Clojure.

Hi,
I have a simple general question about variables used in Clojure.
Often you have an object that must be referenced because it is
established at run time and not known beforehand. Lets say we have
an block object and it has a certain height. We create a reference
to the block's height and u

I'm trying to get the midi sound class in Java to work in Clojure.
Everything seems to work fine except for the conversion of the

used for retrieving data dynamically from a map?

Hi,
Can anybody explain to me how to create a multidimensional array of
floats such as:
[[1.0 1.0 2.0 2.0] [3.0 2.2 4.0 0.0]]
Anything I try gives me errors.

Hi all,
Can anyone help me with this? I have a program with multiple
files. The program uses various data references, which may be
accessed from different files. To facilitate this I usually put ref
variables in a separate file and then :use that file in all the
various modules that make up
.This is done all the time, but I have
no idea how to do it in Clojure.

I have a keyboard paste problem, but I think it has more general

the clipboard will be pasted into the text. I want to act on that
pasted text. I can easily capture the keystroke. The problem is
that my capture takes place BE
Yes, but I don't want to load all the parts at once. I may have four

it's dynamic and why I have the
problem in the first place.

It is as simple as that. What I'm really working on is my own

The confusion over type and instance was a sloppy example. Sorry.
But in your solution I'm confused by one thing. You create and

it.
This has two problems. One is that the loaded data is not
permanent. The other is that th
