The document provides an introduction to Apache Camel, an integration library for Java that facilitates enterprise application integration (EAI) and employs enterprise integration patterns (EIPs). It outlines key features of Apache Camel, including its lightweight nature, ease of configuration, and routing capabilities, as well as basic architectural concepts such as Camel context, routes, and endpoints. The document emphasizes the importance of etiquette during presentations and includes a dependency example for using Apache Camel with Spring Boot.
Introduction to Apache Camel
- 1. Presented By: Mohd Uzair & Akshit Kumar Introduction to Apache Camel
- 2. Lack of etiquette and manners is a huge turn off. KnolX Etiquettes Punctuality Respect Knolx session timings, you are requested not to join sessions after a 5 minutes threshold post the session start time. Feedback Make sure to submit a constructive feedback for all sessions as it is very helpful for the presenter. Silent Mode Keep your mobile devices in silent mode, feel free to move out of session in case you need to attend an urgent call. Avoid Disturbance Avoid unwanted chit chat during the session.

- 4. What is EAI Enterprise application integration (EAI) is the task of uniting the databases and workflows associated with business applications to ensure that the business uses the information consistently and that changes to core business data made by one application are correctly reflected in others. EAI provides a methodology that helps these disparate applications share data and workflows to reduce manual steps and errors and to provide better insight into organizational data.
- 5. What is EIP EIPs (in short) are known design patterns that provide solutions to issues/problems faced during application integration. Need of EIP: ● Applications are heterogeneous in nature, they are developed using different languages, runs on different OS’es, understand different data formats. ● Applications undergo a lot of change, they are subjected to upgrades, and their API’s change over time. ● They need to exchange data over networks in a reliable and secure manner.
- 6. Introduction to Apache Camel Apache Camel is an integration library for Java. It provides a set of Java APIs which help you integrate and process data between different computer systems. In other words, Camel is like the glue between different applications.
- 7. What is Apache Camel used for? Whenever you need to move data from A to B, you can probably use Apache Camel. Using Apache Camel we can do the following: • Pick up invoices . • Moving document. • Invoking a web service. • Turn some XML documents into CSV files. • Make a web service.
- 8. Features Apache Camel provides the following features. 1. Light-weight Open Source 2. Easy Configuration 3. Routing and Mediation Engine 4. A domain-specific language (DSL) 5. Enterprise integration patterns (EIPs)
- 9. Architecture
- 10. Camel Context ● Camel provides a runtime engine, called the Camel Context, which runs your integrations. It’s kind of like a mini application server, embedded inside your Java application. ● The Camel Context runs your integrations and is generally responsible for moving data through the system. ● The simplest way of starting Camel is to create an instance of DefaultCamelContext (which implements the CamelContext interface) and call the start method: CamelContext context = new DefaultCamelContext(); context.start();
- 11. Route A route usually consists of a series of steps. The first step receives or fetches some data, and then the data is passed through subsequent steps to the end of the route. A simple route definition looks something like this (in Camel’s Java syntax): from("file:documents/invoices") .to("file:documents/done");
- 12. Endpoint ● In Camel, an Endpoint is an interface through which Camel exchanges a message with another system. Camel can receive a message from an Endpoint, or send a message to an Endpoint. ● Endpoints are the physical representations of the external applications in your routes, and you declare them using a URI.
- 13. Component ●To allow Camel to create an Endpoint, it uses a Component. ●A Component is simply a specialised plug that allows you to connect to an external system, such as a file on disk, a mailbox, or an application like Dropbox or Twitter.
- 14. Apache Camel- Dependency Here is the dependency for Apache camel using spring boot: <dependency> <groupId>org.apache.camel.springboot</groupId> <artifactId>camel-spring-boot-starter</artifactId> <version>3.17.0</version> </dependency>
