I am getting error in unmarshalling to custom data format. It is working
successfully in Java DSL approach, now I need to convert it in Spring DSL
where I am getting error.
camel-context.xml
<bean id="wynFlatFileDataFormat"
class="ign.wyn.integration.common.dataformat.csv.WynFlatFileDataFormat" />
<camelContext trace="true"
xmlns="http://camel.apache.org/schema/spring";>

<camel:from uri="direct:processFileImport"/>
<camel:unmarshal>
<camel:custom
ref="wynFlatFileDataFormat"/>
</camel:unmarshal>
<camel:to uri="direct:generateOutput" />
</camel:route>
</camelContext>
WynFlatFileDataFormat -

}
}
WynFlatFileDefinitionBean -

Working Java DSL Statement for the same -
from("direct:processFileImport").unmarshal(new
WynFlatFileDataFormat()).to("direct:splitData");
Would appreciate any help!
Thanks,
Amruta
