Apache Camel is an open source integration framework designed to facilitate application messaging using enterprise integration patterns. It supports over 180 components and provides a domain-specific language (DSL) for configuring routing and mediation tasks across diverse technology stacks. The document outlines its architecture, use cases, and integration goals exemplified through various code snippets.

4. What is Apache Camel
 Quote from the web site
 http://camel.apache.org
Apache Camel is a
powerful Open Source
Integration Framework
based on known
Enterprise Integration Patterns

5. What is Apache Camel
 Why do we need integration?
 Your apps are build using different tech stacks
 Critical for your business to integrate
 Why Integration Framework?
 Framework do the heavy lifting
 Focus on business problem
 Not "reinventing the wheel"

send to
B
filter
message

12. Camel’s architecture

13. Filter Route
Endpoint A =
endpoint("activemq:queue:quote");
Endpoint B = endpoint("mq:quote");
Predicate isWidget =
xpath("/quote/product = ‘widget’");
from(A).filter(isWidget).to(B);

14. Filter Route
import org.apache.camel.builder.RouteBuilder;
public class FilterRoute extends RouteBuilder {
public void configure() throws Exception {
Endpoint A = endpoint("activemq:queue:order");
Endpoint B = endpoint("mq:inventory");
Predicate isWidget = xpath("/quote/product = ‘widget’");
from(A).filter(isWidget).to(B);
}
}

15. Content Based Router

16. Content Based Route – Java DSL
from("activemq:orders")
.choice()
.when() .jsonpath(“$..order[?@.type==’cod’)]”)
.to("activemq:codOrders")
.otherwise()
.to("activemq:prepaidOrders");

17. Camel Components

18.  Summary
 Integration framework
 > 180 components out of the box
 Enterprise Integration Patterns (EIP)
 Routing and mediation
 Domain Specific Language (DSL)
 Endpoints as URIs
 Predicate and Expressions
 Very extensible and configurable
 No heavy specification
 No container dependency
 Payload agnostic
 Connectivity to a great wealth of transports
 Apache licensed

19. Code Example
 Goals
1) Pickup files from a directory
2) Make sure we only pickup 3 files per 30 seconds
3) Store into JMS queue
4) Listen on JMS queue
5) And upload file to FTP server
