Web Application Development in Clojure

I did some coding in Scheme and Ruby last couple of months and felt that writing Java code is not fun anymore. But Java as a platform is really good for
most of the tasks and I started to learn some Clojure because there is support for reusing Java libraries in Clojure and it’s a really good mordern [Lisp](http://en.wikipedia.org/wiki/Lisp_(programming_language) derivative.

I’m new to Clojure and I found the series of blog posts by Eric Rochester is really helpful to understand basic stuff for a beginner like me. Please keep in mind that there are some incompatibilities in the code of above blog posts with the new Clojure versions.

As a start I started to re-wrtie a partially done Java Web Service in
Clojure as a REST service. So I googled for resources on Clojure web
appliction development and found this tutorial. That is really good tutorial for beginners and it covers most of the basic concepts of Ring, Compojure and Hiccup. But there were some small issues and most of the solitions can be found in the comments section. My code for above tutorial can be found here.

There are slight changes in my code when compared to code in the

I learned several things by doing this excercise. One thing is support
for WAR deployment is still in early stage. Mostly it’s hard to find
good resources online. And the other thing is some of the most popular
tutorials available online are outdated. This is mainly due to rapid
changes(development) in Clojure eco-system. Finally there are some stuff
which works with Jetty adapter doesn’t work when deploy the WAR in a
custom context and I couldn’t find any tutorial which talks about these
things. I think wrap-if concept introduced in Clojure web app development [tutorial]((http://mmcgrana.github.com/2010/07/develop-deploy-clojure-web-applications.html) I mentioned above will be really helpful to handle development and production configurations.

IMO, If you are new to web application development in Clojure following
resources will be really helpful to you.

If you are thinking of developing web applications in Java, consider
moving to Clojure. It’s really fun than developing in Java ;-).

LaTeX is the de-facto standard for academic writing. And there are several editors available for LaTeX. But the problem with these editors and generally editing LaTeX in any editor like Emacs is the fact that LaTeX is not writer... Continue →
