+# Kotlin Servlet Web Application Example With Maven
+
+This example is a **maven** version of **servlet-web-applications** example built using gradle.
+
+Since this example illustrates the use of a REST endpoint, you will need to run this on a web application server.
+
+## Prerequisites to running the example
+
+ * download Maven directly from the [Apache Maven homepage](http://maven.apache.org/download.html)
+ * install and configure your system as described in [the installation section](http://maven.apache.org/download.html#Installation)
+
+## Folder Structure
+
+Sources
+
+    /src/main/kotlin
+
+Build/War File
+
+    /target/kotlin-test-servlets.war
+
+
+## Compiling/Building the example's war file
+
+If you have maven on your path, type:
+
+	mvn clean package
+
+This will compile:
+ * src/main/kotlin/HomeController.kt and builds a war file named **kotling-test-servlets.war** into **/target** folder
+
+
+## Running the example's war file
+
+Once you compiled the sources with previous 'mvn clean package' command, you can see the 'war' file under '/target' folder. 
+
+Now copy the 'war' file and deploy to any web application server like Tomcat, Jetty etc.
+
+After the deployment is done successfully, open a browser and point to a url like this
+
+    http://localhost:8080/kotlin-test-servlets/hello
+
+You should see an output as below:
+
+    Hello, World!
