How to build runnable JAR using Javalite framework as standalone http? - jar

Question

As questioned, how to build runnable JAR using Javalite framework?
Javalite doesn't have known entry point / main class. I browse some of the examples but not found any clue.
This jar will run as stand-alone on server using java -jar command.
Below snippet of my plugin on pom.xml file
Packaging
<modelVersion>4.0.0</modelVersion>
<groupId>org.javalite</groupId>
<artifactId>activeweb-simple</artifactId>
<packaging>jar</packaging>
<version>1.1-SNAPSHOT</version>
<name>ActiveWeb Example WebApp</name>
Plugin
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<!-- Jar file entry point -->
<mainClass>com.company.Application</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
And the Application.java,
public class Application {
public static void main(String[] args) throws Exception {
String webappDirLocation = "src/main/webapp/";
Tomcat tomcat = new Tomcat();
String webPort = System.getenv("PORT");
if(webPort == null || webPort.isEmpty()) {
webPort = "8081";
}
tomcat.setPort(Integer.valueOf(webPort));
StandardContext ctx = (StandardContext) tomcat.addWebapp("/", new File(webappDirLocation).getAbsolutePath());
System.out.println("configuring app with basedir: " + new File("./" + webappDirLocation).getAbsolutePath());
File additionWebInfClasses = new File("target/classes");
WebResourceRoot resources = new StandardRoot(ctx);
resources.addPreResources(new DirResourceSet(resources, "/WEB-INF/classes",
additionWebInfClasses.getAbsolutePath(), "/"));
ctx.setResources(resources);
tomcat.start();
tomcat.getServer().await();
}
}
Note : I'm currently using tomcat as embedded http-server to enable the JAR file run as stand-alone. But, Javalite ActiveWeb probably has a way for this.

You can build any number of different types of JavaLite projects, such as standalone that use some features: JavaLite HTTP, ActiveJDBC, JavaLite Async, etc. In addition, if you want to build a web application, you also will need ActiveWeb.
Here is a list of examples from the JavaLite repo:
ActiveJDBC:
https://github.com/javalite/standalone-example
https://github.com/javalite/simple-example
https://github.com/javalite/ant-example
https://github.com/javalite/activejdbc-gradle
https://github.com/javalite/multiple-db-example
ActiveWeb:
https://github.com/javalite/activeweb-simple
https://github.com/javalite/kitchensink
https://github.com/javalite/activeweb-secure
https://github.com/javalite/activeweb-bootstrap
https://github.com/javalite/activeweb-lessc
Every example app has a README file you can read to see what the example is for.
In order to start any project, just clone a repo, get it running then start modifying it to your liking.
Additionally, pay attention to the Releases page http://javalite.io/releases and keep your dependencies up to date.
