Exception using Jackson JSON library with camel - json

Question

I am having trouble using the Jackson JSON library with camel.
The exception is:
FailedToCreateRouteException: Failed to create route... because of Data format 'json-jackson' could not be created. Ensure the data format is valid and the associated Camel component is present on the classpath
Here is the beginning of classpath notice that the Jackson libs are there:
<<< camel-maven-plugin:2.9.0:run (default-cli) # portlistener <<<
--- camel-maven-plugin:2.9.0:run (default-cli) # portlistener ---
Classpath = [file:/C:/Users/andrew.b-ext/Workspace/portlistener/target/classes/, file:/C:/Users/andrew.b-ext/.m2/repository/org/codehaus/jackson/jackson-asl/1.9.13/jackson-core-asl-1.9.13.jar, file:/C:/Users/andrew.b-ext/.m2/repository/org/codehaus/jackson/jackson-mapper-asl/1.9.13/jackson-mapper-asl-1.9.13.jar, file:/C:/Users/andrew.b-ext/.m2/repository/org/codehaus/jackson/jackson-jaxrs/1.9.13/jackson-jaxrs-1.9.13.jar, ...snip...
My pom has Jackson:
<properties>
<camel.version>2.12.2</camel.version>
<cxf.version>2.7.8</cxf.version>
<activemq.version>5.6.0</activemq.version>

</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-jaxrs</artifactId>
<version>1.9.13</version>
</dependency>
Here is my definition of the Dataformat object:
<bean id="jsonDataformat" class="org.apache.camel.model.dataformat.JsonDataFormat">
<property name="unmarshalType" value="java.util.Map" />
<property name="library" value="Jackson"></property>
</bean>
I tried changing the jsonDataformat declaration to:
<camel:dataFormats>
<camel:json id="jsonDataformat" library="Jackson"/>
</camel:dataFormats>
When I do that I get a different error:
Configuration problem: Cannot locate BeanDefinitionParser for element [dataFormats]
Can anyone see what I'm doing wrong?
Thanks,
Andrew

Answer 1

You are missing the camel-jackson dependency:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-jackson</artifactId>
<version>${camel-version}</version>
</dependency>
This pulls in jackson-core-asl and jackson-mapper-asl, but unfortunately not jackson-jaxrs. For the latter you still need an explicit dependency in a compatible version.
