Hello,
I want to use jacksonXml as the xmlDateFormat for my Rest bindings.
restConfiguration()
.bindingMode(RestBindingMode.json_xml) // or auto
.jsonDataFormat("jackson")
.xmlDataFormat("jacksonXml“)
Note, I am also using Spring Boot and have the following dependency added.
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-jacksonxml-starter</artifactId>
</dependency>
camel-jaxb is not on the classpath.
When I start my application, I get this:
Caused by: java.lang.IllegalArgumentException: Cannot find
RestBindingJaxbDataFormatFactory on classpath. Add camel-jaxb to classpath.

When I add camel-jaxb, then I get this:
Caused by: java.lang.ClassCastException: class
org.apache.camel.component.jacksonxml.JacksonXMLDataFormat cannot be cast to
class org.apache.camel.converter.jaxb.JaxbDataFormat
(org.apache.camel.component.jacksonxml.JacksonXMLDataFormat and
org.apache.camel.converter.jaxb.JaxbDataFormat are in unnamed module of loader
'app')

~[camel-support-4.14.1.jar:4.14.1]
Looking at the code, it seems like even though jacksonXml has been defined as
the data format, it will still try to load the JaxbDataFormat via the
RestBindingAdviceFactory.
if (jaxb != null) {
// to setup JAXB we need to use camel-jaxb
PluginHelper.getRestBindingJaxbDataFormatFactory(camelContext).setupJaxb(camelContext,
config,
bc.getType(), bc.getTypeClass(),
bc.getOutType(), bc.getOutTypeClass(),
jaxb, outJaxb);
}
The variable jaxb is not null, because "jaxb =
camelContext.createDataFormat(name);“ and it will be of type
JacksonXMLDataFormat.
Am I missing a configuration, or is Jackson XML not meant to work with Rest?
Thank you in advance.
Regards,
Arne B.
