Full Content Camel 2.12.0 release (currently in progress) New and Noteworthy Welcome to the 2.12.0 release which approx XXX issues resolved (new features, improvements and bug fixes such as...) Endpoint Annotations along with automatically created HTML documentation for the endpoint parameters; this makes it easier for component developers to add a few refactoring-safe annotations to their Endpoint or Consumer implementations and, (along with javadoc comments on the field or setter method), get nice user documentation on how to use the endpoint for free. ComponentConfiguration API provides a handy API for tools developers to introspect on a Component to find all the possible parameters, their types and any extra annotations (like Bean Validation Annotations) to be able to create/edit endpoints or URI strings so that tools can generate nicer UIs for configuring endpoints than just letting folks edit Strings. EndpointCompleter API provides a hook so that command line tools (like Karaf's shell), IDEs and web tools can get (bash tab like) auto-completion on endpoint paths (such as file or directory names, message queue names, database table names) when creating or using new endpoints Reduced stack-frames in use during routing, that also makes Camel's stack traces being logged much less verbose. This also allows people to easier debug the internals of Camel as less AsyncCallback callbacks are in use during routing. Easy to use Message History out of the box. And included message history as "route stack-trace" when exceptions logged by Error Handler to make it easier for end users to spot where the exception occurred. Spring Web Services now supports setting/receiving SOAP headers more easily using a header on the Camel Message. Evaluating Groovy expressions is faster as we cache the compiled scripts. Added base64 option to Shiro Security to allow transferring security token over JMS and other transports as base64 encoded representation. Made it easier to use Shiro Security as the credentials can be provided in headers, when sending a message to a secured route. Bindy now supports enums. Added new BacklogDebugger to perform live debugging of messages during routing. The BacklogDebugger has JMX API allows tooling to control the debugger. While using the Jackson library through the JSON Dataformat there's now a jsonView attribute you could make use of directly inside the DSL itself. SMPP now supports optional parameters in all commands where they are possible. JDBC now supports named parameters. Added timeout support for Direct producers to wait for consumer to become active. Added stats action to ControlBus to easily get performance statics in a single XML message. Added support for request timeout on Netty producer, and to configure logging level on Netty consumer to be less noisy for ChannelClosedException which can flood the logs when client disconnects abruptly. Spring Batch component producer now returns the JobExecution instance as the output message. Users can use the JobExecution instance to perform some operations using the Spring Batch API directly. Added support for NULL values in SQL with named parameters. Optimized Jetty streaming responses in non-chunked mode; and as well using buffer sizes based on HttpServletResponse.getBufferSize() instead of fixed size of 4kb. Added greedy option to scheduled polling consumer. Added support for accessing the length field on Java arrays in Simple language. Added support for using JAXB annotations with Camel's Jackson JSON component. Added the ability for Bindy to skip content when parsing fixed-length records. MongoDB now supports aggregation queries. Netty allows to use shared Netty boss and worker thread pools. The Camel Maven Archetypes for component and data format now packages as OSGi bundles out of the box. Easier Stream caching configuration using StreamCachingStrategy. Also allows spool directory per CamelContext instead of shared per JVM. And insight at runtime using JMX management. As well allowing to plugin 3rd party implementations. Improved Netty to be able to join an UDP multicast group. Using Camel Spring is now setting up Camel routes later in the process allow Spring to complete all of its dependency injection, before Camel RouteBuilder instances is configured. This allows to safely use Spring dependency injection in these RouteBuilder classes. Services in a CamelContext which can only be enlisted once (eg it similar to a static in a JVM) has simpler and fixed MBean names in JMX. JDBC based aggregation repository for the Aggregate EIP now supports optimistic locking, allows clustered Camel applications to use a shared database for the aggregation repository. Recipient List stores a property (Exchange.RECIPIENT_LIST_ENDPOINT) on the Exchange with the URIs of the Endpoint the message was sent to. Added sanitize option to Camel JMX to hide sensitive information such as passwords. Fixed Issues Fixed setting .id in Java DSL on some EIPs such as the Validate Fixed Dead Letter Channel always handled exception, which wasn't the case if an Exception Clause was in use, which didn't had handled=true. Fixed Using PropertyPlaceholder in attributes defined on <camelContext>. All Camel Components will configure their consumers when being created to ensure you can configure from URIs with consumer. as prefix. Fixed QuickfixJEndpoint to adhere a given InOut MEP correctly. Fixed using property placeholders in a Simple predicate used inside a when in a Content Based Router when using Java DSL Fixed a race condition in File consumer which may lead to a tiny window for another process to pickup a file, as the read lock is committed before the file is moved afterwards etc. Now read locks is executed last. HTTP4 now validates that only one instance of org.apache.camel.util.jsse.SSLContextParameters is used per component, as multiple is not supported, and could lead to undesired side effects. Fixed possible dead-lock during Graceful Shutdown if a route starts from SEDA and uses Splitter or Multicast and maximumRedeliveries was enabled as well. Fixed TokenizeXML to support self closing tags. Fixed Blueprint Testing to work with isMockEndpointsAndSkip and other similar functionality of the CamelBlueprintTestSupport class. Fixed Routing Slip to emit ExchangeSentEvents also Fixed Quartz routes with stateful jobs may not trigger if redeployment with changed endpoint uris. Fixed Routing Slip and Dynamic Router EIPs to work with Stream caching New Enterprise Integration Patterns New Components camel-disruptor - SEDA behavior using the ultra-fast LMAX Disruptor library. camel-geocoder - For looking up geocodes (latitude, longitude) for a given address, or reverse lookup with Java API for Google Geocoder camel-leveldb - Added docs for this component. camel-mustache - For templating using Mustache camel-mvel - For templating using MVEL camel-netty-http - HTTP component using Netty as transport camel-sap-netweaver - For integration with SAP NetWeaver Gateway camel-stomp - For communicating with Stomp compliant message brokers, like Apache ActiveMQ or ActiveMQ Apollo camel-weather - For polling weather information from Open Weather Map camel-yammer - Allows you to interact with the Yammer enterprise social network camel-rabbitmq - Allows you to interact with the RabbitMQ. New DSL New Annotations New Data Formats New Languages New Examples MyBatis Example Netty HTTP Server Example New Tutorials API changes The interface org.apache.camel.api.management.mbean.ManagedTracerBacklogMBean has been renamed to org.apache.camel.api.management.mbean.ManagedBacklogTracerMBean Added inMemory, and length methods to org.apache.camel.StreamCache Changed the parameter type ProcessorDefinition to NamedNode on method getObjectNameForProcessor in interface org.apache.camel.spi.ManagementNamingStrategy Added removeTypeConverter method to org.apache.camel.spi.TypeConverterRegistry Known Issues Dependency Upgrades AHC 1.7.11 to 1.7.19 AWS Java SDK 1.3.27 to 1.5.1 Beanio from 2.0.5 to 2.0.6 Bouncy Castle 1.47 to 1.49 Commons Codec 1.6 to 1.8 Commons Net 3.1 to 3.3 Commons Httpclient 4.2.3 to 4.2.5 Commons Httpcore 4.2.3 to 4.2.4 CXF 2.7.4 to 2.7.6 Ehcache 2.5.2 to 2.7.2 HAPI 2.0 to 2.1 Groovy 2.1.3 to 2.1.6 Hawtdispatch 1.13 to 1.17 Hibernate Validator 4.1.0.Final to 5.0.1.Final Jackson 2.1.4 to 2.2.2 Jersey 1.13 to 1.17.1 Jettison 1.3.3 to 1.3.4 JRuby 1.7.2 to 1.7.4 Krati 0.4.8 to 0.4.9 Leveldbjni 1.6 to 1.7 Mail 1.4.5 to 1.4.7 MongoDB Java Driver 2.9.1 to 2.11.2 MQTT Client 1.4 to 1.5 MVEL 2.1.3.Final to 2.1.6.Final Netty 3.6.5 to 3.6.6 OpenEJB 4.5.1 to 4.5.2 OpenJPA 2.2.1 to 2.2.2 Saxon 9.4.0.4 to 9.5.0.2 Scala 2.10.1 to 2.10.2 Shiro 1.2.1 to 1.2.2 Spring 3.1.4.RELEASE to 3.2.3.RELEASE Spring Batch 2.1.9.RELEASE to 2.2.1.RELEASE Spring Data Redis 1.0.3.RELEASE to 1.0.4.RELEASE Spring Security 3.1.3.RELEASE to 3.1.4.RELEASE Spring Web Services 2.1.2 to 2.1.3 TestNG 6.8 to 6.8.5 XStream 1.4.3 to 1.4.4 Internal changes The following classes in org.apache.camel.processor has been removed as they are no longer needed due internal optimization: UnitOfWorkProcessor, ChildUnitOfWorkProcessor, RouteContextProcessor, RouteInflightRepositoryProcessor, and RoutePolicyProcessor Changes that may affect end users The File and FTP consumers when using idempotent repository will no longer invoke contains with a directory name; this has been changed to only be checked for files. Shutting down using Graceful Shutdown now requires the timeout value to be positive. And improved logic to avoid getting stuck in waiting for inflight messages, and having counter go negative. Tracer now requires explicitly to be enabled on CamelContext to be available and in use. The class org.apache.camel.processor.interceptor.BacklogTracerInterceptor has been removed as it was no longer needed due internal optimizations. The Stream caching default threshold for spooling to disk has been changed from 64kb to 128kb. The unary operators in Simple is now only applied on functions Using Camel Spring is now setting up Camel routes later in the process allow Spring to complete all of its dependency injection, before Camel RouteBuilder instances is configured. This allows to safely use Spring dependency injection in these RouteBuilder classes. Changing destination using JMX on org.apache.camel.api.management.mbean.ManagedSendProcessorMBean no longer supported. Camel now uses xxxxxx instead of ****** when masking passwords (sanitize) when logging URIs in the log. Using xxxxx is more friendly with JMX naming. Important changes to consider when upgrading Spring 3.0.x is no longer supported. The usage of the deprecated built-in CommonsHttpMessageSender has been replaced with HttpUrlConnectionMessageSender by Spring Web Services. Consider this in case either the timeout or sslContextParameters option is used through the Producer of this component. camel-scala-29 module has been removed.
