Failed to create route route-t: >>> OnException[[com.sample] -> - apache-camel

Question

I am migrating from camle 2 to camel 3 as below configuration
<onException>
<exception>com.sample</exception>
<redeliveryPolicy disableRedelivery="true"/>
<handled>
<constant>true</constant>
</handled>
<log message="got here, before predict, ${exchangeProperty.firstCall}" loggingLevel="INFO"/>
<choice>
<when>
<method>operation</method>
<bean ref="Procs" method="SampleCommentRequestForError"/>
<setProperty propertyName="firstCall">
<constant>false</constant>
</setProperty>
<log message="got here, after predict, ${exchangeProperty.firstCallOf}" loggingLevel="INFO"/>
<to uri="direct:sample-comment"/>
</when>
</choice>
<bean ref="abc_errorhandler" method="abcException"/>
</onException>
and getting below exception :
Failed to create route route-nsm-client-call at: >>> OnException[[com.sample] -> [Log[got here, before predict, ${exchangeProperty.firstCall], Choice[[When[bean{abc} [From[direct:bbc-call ->... because of Bean language requires bean, beanType, or ref argument
Caused by: java.lang.IllegalArgumentException: Bean language requires bean, beanType, or ref argument
Any idea on this?

Answer 1

This will work camel 2.x operation but if you try to upgrade camel 3.x for existing code. So, in that case you need to change this code to like below sample . but rather than myBean provide whole class package path.
Try below sample code..
