+## Camel 1.0 Tribute - JMS to File
+
+A tribute to the very first Apache Camel example ever written.
+
+When Apache Camel 1.0 was released in June 2007, the project shipped with just
two examples.
+The first and most iconic was `camel-example-jms-file` - a simple route that
consumed messages
+from a JMS queue and saved them to the file system.
+
+Back then, Camel was still part of the Apache ActiveMQ project. The README was
signed
+_"The Apache ActiveMQ team"_, the website lived at `activemq.apache.org/camel`,
+and classes like `CamelTemplate` (later renamed to `ProducerTemplate`) were
brand new.
+
+The original example looked like this:
+
+```java
+CamelContext context = new DefaultCamelContext();
+
+ConnectionFactory connectionFactory =
+ new ActiveMQConnectionFactory("vm://localhost?broker.persistent=false");
+context.addComponent("test-jms",
+ JmsComponent.jmsComponentAutoAcknowledge(connectionFactory));
+
+context.addRoutes(new RouteBuilder() {
+ public void configure() {
+ from("test-jms:queue:test.queue").to("file://test");
+ }
+});
+
+CamelTemplate template = new CamelTemplate(context);
+context.start();
+
+for (int i = 0; i < 10; i++) {
+ template.sendBody("test-jms:queue:test.queue", "Test Message: " + i);
+}
+```
+
+That was 40+ lines of Java, a Maven project, ActiveMQ embedded in-process,
+and manual component wiring.
+
+Today, the same example is a single YAML file and one command.
+
+### Running the example
+
+Start an Apache ActiveMQ Artemis broker:
+
+```sh
+$ camel infra run artemis
+```
+
+Or with Docker manually:
+
+```sh
+$ docker run --detach --name mycontainer -p 61616:61616 -p 8161:8161 --rm
apache/activemq-artemis:latest-alpine
+```
+
+Then run the example:
+
+```sh
+$ camel run *
+```
+
+Camel will send 10 test messages to the `test.queue` JMS queue (just like the
original)
+and consume them back, saving each message as a file in the `test` directory.
+
+### What changed in 19 years
+
+| | Camel 1.0 (2007) | Camel CLI (today) |
+|---|---|---|
+| **Language** | Java (40+ lines) | YAML (25 lines) |
+| **Build** | Maven project with pom.xml | No build needed |
+| **Broker** | Embedded ActiveMQ (in-process) | Apache ActiveMQ Artemis
(container) |
+| **Component setup** | Manual `ConnectionFactory` wiring | Auto-configured
via properties |
+| **Run command** | `mvn camel:run` | `camel run *` |
+| **Dependencies** | Declared in pom.xml | Auto-downloaded |
+
+What stayed the same: `from("jms:queue:test.queue").to("file://test")` - the
core routing idea
+that made Camel what it is today.
+
+### Help and contributions
+
+If you hit any problem using Camel or have some feedback, then please
+[let us know](https://camel.apache.org/community/support/).
+
+We also love contributors, so
+[get involved](https://camel.apache.org/community/contributing/) :-)
+
+The Camel riders!
