Camel 1.5.0 release

New and Noteworthy

Welcome to the 1.5.0 release which approx 266 issues resolved (new features, improvements and bug fixes such as...)

• support for Guice for dependency injection along with a new Guice JMS Example
• major improvements in FTP and File components
• File consumers now default uses exclusive read locking when it consume files, meaning that they wont consume files that are in the progress of being written by third part. The FTP consumer has this support as well, however it is disabled by default as it requires write privileges.
• File and FTP component supports expression to set dynamic filename patterns instead of using the FileComponent.HEADER_FILE_NAME header. See File Language for samples and use cases.
• important changes in ProducerTemplate (see below)
• Exception Clause now supports marking exceptions as being handled so callers doesn't receive the caused exception, but you can set the response to return instead. This is a very important feature.
• various improvements in Flatpack and XMPP components
• minor improvements in CXF, SpringIntegration, HTTP, Mail and Mina components
• minor improvements in Aggregator supporting a better fluent builder, etc.
• splitter now handles streaming avoiding reading entire content into memory (consuming very big 1gb files is now possible)
• introduced new jt400, HL7, LDAP and Smooks components
• introduced Delay Interceptor to slow down processing to show how things is happening nice and slow, so you are not bombarded with zillions of logging output.
• Mail can now send html mails with the new contentType option
• Camel Maven Archetypes now available in m2eclipse Maven project creation
• Java WebStart support
• refinements in loading resources using OSGi bundles, should now handle different OSGi platforms much better
• Type Converter now supports Exchange as 2nd parameter to allow converters access to the Exchange and thus the CamelContext as well. To be used for setting encoding in the future.
• New Loop api in DSL allows processing of a message a number of times, possibly in different ways.
• Spring DSL improve
• improved Tracer formatting and more options for configuration
• improved support for all Endpoints, not just singletons in CamelContext.
• minor tweaks to the Visualisation generator
• IBM JDK support (notable exceptions)

• refinements to run in OSGi containers
• some internal refactorings of package structure to avoid cycle dependencies
• @deprecated some core classes, that will be removed in Camel 2.0

JavaOne Meetup 2008

Come meet with the folks behind Apache ActiveMQ, Camel, CXF and ServiceMix at JavaOne!

In an attempt to help predict the head count, please add your name to the registration page.

A couple weeks ago I spoke at ApacheCon EU 2008 in Amsterdam, The Netherlands about Apache Camel. If you weren't able to attend, don't worry as the presentation, named Take Apache Camel for a Ride can be downloaded now. If you have any questions, please contact me as my presentations don't contain many bullet points because I tend to elaborate verbally on the topic.

We are very pleased to announce the new Camel 1.3.0 Release which includes 208 new features, improvements and bug fixes such as...

• improved Bean Integration
• improved testing via Spring Testing along with the Mock, Test, DataSet components

• default to more efficient JMS usage when working with Spring 2.5.x to avoid a previous Spring bug
• various improvements in the DSL and with error handling
• improved automatic Type Converter implementations
• method invocations now supported in EL expressions
• CXF transport API now supported in CXF component, you could leverage the power of Camel mediation in Apache CXF

New Components

• AMQP
• DataSet for easier load testing
• JCR for JSR 170 support

The Camel riders

I'm pleased to announce the Apache Camel 1.2.0 Release has been made! Its packed with a ton of new feature such as:

• Data Format to support pluggable marshalling and unmarshalling of data in various formats like JAXB, XML Beans, Serialization or Artix Data Services
• hugely improved CXF integration for working with JAX-WS and Apache CXF while reusing powerful Camel routing.
• improved support for Asynchronous Processing within components such as for HTTP and SEDA
• improved OSGi support with both component discovery using the OSGi registry and turning Camel into OSGi bundles.
• improved Visualisation
• support for the full WSDL Message Exchange Patterns
• more powerful Bean Integration

Go take it for a ride!

There is a new short ScreenCast from James Strachan which gives a brief introduction to Apache Camel and the Enterprise Integration Patterns. Check them out!

• Introduction to Camel and Enterprise Integration Patterns (Medium Resolution)
• Introduction to Camel and Enterprise Integration Patterns (High Resolution)

We now have a nice EIP Visualisation maven plugin available! So you can now easily generate nice graphical reports of your EIP routing rules from your application code.

We've also added the generation of these EIP diagrams to the standard maven reports via the Camel Maven Plugin. For example here's the generated example routing rules for the camel-spring module. Notice how you can click on most of the EIP nodes to go to the pattern page! And hover over a node to get more detailed description etc.

For a description of theplugin and how it works is see here.In summary; just add the camel-maven-plugin to your <reporting> section of your pom.xml then make sure you have a META-INF/spring/*.xml in your classpath which configures your EIP routing rules (via Java or XML). Note that if you do not intend to include a META-INF/spring/*.xml file in your jar, you could put this in the src/test/resources directory so it will only be used for generating the reports.

James Strachan was interviewed by Dana Gardner on Apache Camel and its DSL and support for Enterprise Integration Patterns. Read the transcript or check out the podcast.
