Never encountered one of those before -- maybe that is a good thing! :) After a little study, I was able to write a simple servlet, compile it with Leiningen, and make a WAR using Maven. This might be no big news to the Java literati in the audience, but it's all new to me. :) I thought I'd share my notes here, in case anyone else is trying to do the same thing. There is a copy of my work here: http://github.com/gmfawcett/simplest The basic recipe I followed is there, and for lazier readers it also appears below. Many thanks to yogthos' clojure-maven-examples, which answered many questions (though it uses clojure-maven-plugin, and does not use Leiningen): http://github.com/yogthos/clojure-maven-examples Best, Graham * Start a new project with Leiningen (I'm using Leiningen 1.0.1): $ lein new simplest * Add your servlet. I put mine in 'src/simplest/servlet.clj': (ns simplest.servlet (:gen-class :extends javax.servlet.http.HttpServlet)) (defn -doGet [this req resp] ...) * Add your dependencies to the project file. I added [javax.servlet/servlet-api "2.5"]. * Set the :compile-path, so that the classfiles end up where Maven will expect to see them: (defproject simplest "1.0.0-SNAPSHOT" :compile-path "target/classes" ...) * Compile it with Leiningen, to make sure there aren't any errors: $ lein compile [copy] Copying 3 files to /tmp/simplest/lib Compiling simplest Compiling simplest.servlet * Add the web.xml file and whatever static resources you want under 'src/main'. I added: src/main/webapp/WEB-INF/web.xml src/main/webapp/index.html My web.xml is basic: <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns="http://java.sun.com/xml/ns/javaee"; xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"; xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"; id="simplest" version="2.5"> <display-name>Simplest Clojure Servlet</display-name> <servlet> <servlet-name>simplest</servlet-name> <servlet-class>simplest.servlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>simplest</servlet-name> <url-pattern>/simplest/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> </welcome-file-list> </web-app> * Make your POM file for Maven: $ lein pom Wrote pom.xml * Generate the WAR file: $ lein compile; mvn war:war .... $ ls target/*.war target/simplest-1.0.0-SNAPSHOT.war * QED! * If you want, you can add a 'Jetty plugin' to your pom.xml. This will enable Maven to run your servlet(s) for you in a standalone Web server, for testing: Edit pom.xml: see http://github.com/gmfawcett/simplest/commit/44d978c55ae02112647a743b6f957156787fba25 $ lein compile; mvn jetty:run # visit your servlet at http://localhost:8080/ Lacking proper Leiningen/Maven integration, it's a good idea to always call 'lein compile' before you run a Maven command.
