Hello,
weird, I know, but I have keywords in a map like this:
:first/second
I want to convert such a keyword to a string and I'm doing this with the
"name" function. This doesn't work with a slash:
(def x :first/second)
(name x)
"second"
(The reason why I have such keywords at all is that d

Thanks for the quick response!
BTW: Does someone know how I can keep the connection always open? If I

each time it gets called. Isn't this quite inefficient?

Interesting, I can run the code by building it via "Run ..". It works
fine within IDEA. But not via Idea's REPL.
So no firewall issue (I have no zonealarm or any other local firewall
running).
Looks like the REPL in IDEA has really a problem establishing a socket
connection.

package that ships with Stuart's "Programming Clojure" and that was
success!
So I think there is a problem with my "la clojure" REPL. Looks like
it does not allow me to establish a tcp/ip connection?
Any ideas?
