Apache Camel is a powerful integration framework that allows you to build robust and reliable applications by connecting different systems and components. Exception handling is a crucial aspect of building fault-tolerant Camel routes. In this tutorial, we will explore two approaches for handling exceptions in Apache Camel: using onException to handle multiple exceptions and utilizing .doTry(), .doCatch(), .doFinally() blocks.

How to use Camel JPA with Spring Boot
In this tutorial, we’ll learn how to use the Camel JPA component to read and write data from a PostgreSQL database. Specifically, we’ll cover how to create a Camel route that reads data from a JSON file, maps it to a JPA entity, and then inserts it into a PostgreSQL database using the Camel JPA component. We’ll wrap it all into a Spring Boot application.
How to send JMS Messages from Camel to WildFly
This tutorial discusses how to send messages using the Camel JMS Component to a remote ArtemisMQ embedded in a WildFly distribution. This example will use a Camel standalone application. If you want to use a Spring Boot application, then check this article: JMS Messaging with Spring Boot and Artemis MQ
Using the Routing Slip EIP with Camel
The Routing Slip EIP (Enterprise Integration Pattern) is a powerful tool that enables us to route a message through a series of processors based on a predetermined set of rules. The routing slip is essentially a list of destinations that a message must pass through before reaching its final destination. In this tutorial, we will learn how to use the Routing Slip EIP in Apache Camel.
Camel Processor made simple
The Camel Processor is a key building block of Camel, and gives you full access to the message being transferred including the message body, any headers, and any properties associated with the message. By creating a Processor you can modify any of those elements, for example you can alter the body of the message transforming it from XML to CSV or you can add custom properties or headers to it. Let’s see how to build a custom Processor which transforms the body of a Message.
How to transform data from XML to JSON with Camel
This article discusses how to transform data in a Camel route from XML to JSON using Jackson data format XML library. To test our Camel Route, we will include it in a Spring Boot application which receives as input an XML in its REST Controller.
How to integrate Camel Java DSL with XML
Integrating a Camel DSL with an XML DSL in a Spring Boot application can be a powerful way to combine the flexibility and ease of use of Camel’s Java DSL with the simplicity and readability of XML configuration. This tutorial will guide you through the process of integrating the two DSLs, using the provided code as an example.
