The document discusses Apache Camel and Enterprise Integration Patterns (EIPs). It provides an overview of Camel, its architecture including CamelContext, Registry, Exchange, and Components. It then discusses how various EIPs like Content Based Router, Message Filter, Recipient List, Dynamic Router, Splitter, Aggregator, Resequencer, and Dead Letter Channel are supported in Camel using nodes like filter, multicast, dynamicRouter, split, aggregator, resequence. It concludes with a brief mention of a demo.

2. Agenda
• What is Apache Camel ?
• What is EIP ?
• EIP with Apache Camel
• Example
• Demo

21. • CamelContext object represents the Camel runtime system.
• Registry:Holds all the bean necessary for routings.
• Exchange: contains message related headers properties.
• TypeConverter:Type conversion utility for converting types.
• Component is a factory for creating Endpoint instances.
• Endpoints implemented with many different communication
technologies.
• JMS queue
• Web service
• File
• FTP server
• Email Address
Camel Architecture

23. EIP with Camel

25. Content Based Router

26. • Camel supports the
message translator
using the processor,
bean or transform
nodes.

27. Message Filter EIP
• Camel has support for Message Filter using
the filter node
from("jms:queue:inbox")
.filter(header("test").isNotEqualTo("true"))
.to("jms:queue:order");

28. Recipient List
• How to route messages based on a static or
dynamic list of destinations
• Camel has support for Message Filter using the
filter node
from("jms:queue:inbox")
.multicast().to("file://backup",“seda:inbox");
from("seda:confirmMails").beanRef(processMails)
.recipientList(“destinations")

29. Dynamic Router
from("jms:queue:order")
.dynamicRouter(bean(new MyRouter()));

30. Splitter EIP
• Camel has support for Splitter using the split
node
from("file://inbox")
.split(body().tokenize("n"))
.to("seda:orderLines");

31. Aggregator EIP
• Camel has support for Aggregator using the
aggregator node
from("jms:topic:stock:quote")
.aggregate()
.xpath("/quote/@symbol")
.batchTimeout(5 * 60 *1000)
.to(“seda:quotes");

32. Resequencer EIP
• Camel has support for Resequencer using the
resequence node
from("jms:topic:stock:quote")
.resequence().xpath("/quote/@symbol")
.timeout(60 * 1000)
.to(“seda:quotes");

33. Dead Letter Channel EIP

36. Wiretap
from("jms:queue:order")
.wireTap("seda:tappedOrder")
.to("bean:processOrder");
