Quick start

Your first application

Dependencies

Just add in any Maven pom.xml - or gradle build.gradle the following dependency:

<dependency>
  <groupId>org.apache.meecrowave</groupId>
  <artifactId>meecrowave-core</artifactId>
  <version>${meecrowave.version}</version>
</dependency>

If you intend to reuse our Cli main you should also add:

<dependency>
  <groupId>commons-cli</groupId>
  <artifactId>commons-cli</artifactId>
  <version>1.4</version>
</dependency>

Runtime

Meecrowave relies on JAX-RS and CDI so to start you just need to write a JAX-RS endpoint:

@Path("kitchen")
@ApplicationScoped
public class HelloKitchen {
    @GET
    public String getMenu() {
        return "good things";
    }
}

Then booting Meecrowave is as easy as launching - or reuse org.apache.meecrowave.runner.Cli provided main:

try (final Meecrowave meecrowave = new Meecrowave().bake()) {
    new Scanner(System.in).nextLine();
}

You should get some output containing:

[19:54:55.397][INFO][main][.meecrowave.cxf.CxfCdiAutoSetup] REST Application: / -> org.apache.cxf.cdi.DefaultApplication
[19:54:55.399][INFO][main][.meecrowave.cxf.CxfCdiAutoSetup]      Service URI: /kitchen  -> org.app.HelloKitchen
[19:54:55.401][INFO][main][.meecrowave.cxf.CxfCdiAutoSetup]               GET /kitchen/ ->      String getMenu()

And you can check it works doing:

curl http://localhost:8080/kitchen

You’re in a hurry? Use groovy!

this feature is supported starting from version 0.3.0 only.

Create a file called hello.groovy:

@Grab('org.apache.meecrowave:meecrowave-core:0.3.0')

import org.apache.meecrowave.Meecrowave

import javax.ws.rs.GET
import javax.ws.rs.Path
import javax.enterprise.context.ApplicationScoped

@Path("hello")
@ApplicationScoped
class Hello {
    @GET
    hi() {
        "hi"
    }
}

new Meecrowave().bake().await()

then

groovy hello.groovy

Finally you can test it:

curl http://localhost:8080/hello

And my war?
