Camel Project

You need an Camel Application to monitor. If you don’t have one yet, this guide briefly covers how to create an Apache Camel Project.

🎯 Quick Decision Matrix:

  • Camel JBang: Choose for prototyping, scripting, learning, and quick testing
  • Camel Core: Choose when you need full control and traditional Java application architecture
  • Camel Quarkus: Choose for cloud-native, microservices, fast startup, low memory footprint
  • Camel Spring Boot: Choose for enterprise applications with existing Spring ecosystem

Apache Camel with JBang

Quick Start

Install JBang and Camel CLI:

# Install JBang (Linux/macOS)
curl -Ls https://sh.jbang.dev | bash -s - app install --fresh --force jbang

# Install Camel CLI
jbang app install camel@apache/camel

# Create a simple route
camel init MyRoute.java

This gives you a simple Route:

import org.apache.camel.builder.RouteBuilder;

public class MyRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("timer:java?period=1000")
            .setBody()
                .simple("Hello Camel from ${routeId}")
            .log("${body}");
    }
}

Running

# Use Camel CLI
camel run MyRoute.java

Camel JBang is primary intended to be Camel standalone only but since Camel 4.6 it offers limited support for running with Spring Boot or Quarkus.

Don’t hesitate to run camel --help as CamelJBang supports multiple commands.
