CXF producer

From Camel 1.5.1 the camel-cxf producer's serviceClass parameter should be Interface, before that you could specify the serviceClass as a Class or Interface.

Changes to existing interfaces

• add getTypeConverterRegistry() to CamelContext

Removal of deprecated items

• "initialRedeliveryDelay" in RedeliveryPolicy has been renamed to "delay". You will need to make this change in the Java/Spring DSL usage of the deadLetterChannel, redeliveryPolicy, transactionErrorHandler, and onException.

• CamelTemplate has been removed, use ProducerTemplate instead. It can be created using org.apache.camel.CamelContext.createProducerTemplate().

• exception() has been renamed to onException().

• The beanShell method on ExpressionClause has been removed. Use language("beanshell", text) instead.

• handleAll in try-catch has been renamed to finallyBlock

• trace() has been removed. Please use Tracer Support instead.

• setOutBody() has been removed. Please use transform(Expression) instead.

• setHeader(String name, String value) has been removed. Please use setHeader(String, Expression) instead.

• convertOutBodyTo has been removed. Please use convertBodyTo(Class) instead.

• The "methodName" parameter on a bean endpoint has been renamed to "method".

• On the file endpoint excludedNamePrefixes and excludedNamePostfixes have been renamed to excludedNamePrefix and excludedNamePostfix.

• The QueueCompoenent has been removed. Please use the seda: URI format instead of queue:

• ListPollingConsumer has been removed.

• InvalidHeaderTypeException has been removed. Use InvalidTypeException instead.

• camelContext "useJmx" attribute has been removed. Please use the jmxAgent element instead.

• CamelContext no longer has the following methods: addSingletonEndpoint, removeSingletonEndpoint, setRoutes

• When using TransactionErrorHandlerBuilder, you must use DelayPolicy instead of RedeliveryPolicy.

• The BeanInjector in camel-spring has been removed.

• On Endpoint, getContext() and setContext(CamelContext) have been renamed to getCamelContext() and setCamelContext(CamelContext)

• To set the ignored headers in the http component you must use the HeaderPropagationStrategy instead of setIgnoredHeaders(...)

• JettyHttpProducer has been removed. Use org.apache.camel.component.http.HttpProducer instead.

• In MailConfiguration, getDestination() and setDestination(...) have been renamed to getRecipients() and setTo(...).

• shouldHeaderBePropagated() in HttpBinging has been removed in favour of using HeaderPropagationStrategy

• In camel-ognl, RootObject class has changed getIn/Out to getRequest/Response

• In JmsBinding, instead of get/setIgnoreJmsHeaders, use DefaultHeaderFilterStrategy.get/setOutFilter

• In JmsProducer, getTemplate has been renamed to getInOnlyTemplate

• get/setRequestTimeout on the JmsEndpoint has been removed. You will need to specify this in the JmsConfiguration.

• In CxfBinding, createCxfMessage, storeCxfResponse, and copyMessage all require a HeaderFilterStrategy as a parameter. You can use 'new CxfHeaderFilterStrategy()' for instance.

• In CxfSoapBinding, getCxfInMessage and getCxfOutMessage require a HeaderFilterStrategy as a parameter.

• CxfSoapBinding.setProtocolHeader has been removed, please use CxfHeaderHelper.propagateCxfToCamel instead.

• get/setContext() on the CxfSoapEndpoint has been renamed to get/setContext()

• In camel-jms the RuntimeJmsException, MessagePropertyAccessException, MessagePropertyNamesAccessException, and MessageJMSPropertyAccessException have been removed. CamelRuntimeException will be thrown instead.

• The beanShell method on ScriptBuilder has been removed. Use script("beanshell", text) instead.

• In camel-stream usage of StreamMessage has been replaced by DefaultMessage

• In StreamEndpoint, setFile has been removed. You should use the camel-file component instead.

• In StreamEndpoint, setUrl has been removed. You should use the camel-http component instead.

• serviceActivation has been removed

Aggregator specification in Spring DSL changed

The aggregator expression is now enclosed in a correlationExpression element. You now need to specify an aggregator as:

<aggregator>
  <correlationExpression>
    <simple>header.cheese</simple>
  </correlationExpression>
  <to uri="mock:result"/>
</aggregator>

Known Issues

Important changes to consider when upgrading

JAXB data format

If you use XJC to create the java class from the schema, you will get a ObjectFactory for you JAXB context. Since the ObjectFactory uses JAXBElement to hold the reference of the schema and element instance value, from Camel 1.5.1 jaxbDataformat will ignore the JAXBElement by default and you will get the element instance value instead of the JAXBElement object form the unmarshaled message body.
If you want to get the JAXBElement object form the unmarshaled message body, you need to set the JaxbDataFormat object's ignoreJAXBElement property to be false.
