Hi,
The FallbackTypeConverter just create a JAXB context based on the type class that is annotated with @XmlRootElement,the jaxb context doesn't has all the packages class, but JAXB will add all the types thats relates to this types class.
I just committed [a small unit test|http://svn.apache.org/viewvc?rev=1092615&view=rev
] to reproducer the error, but I had no luck with it. Maybe you can consider to add some annotation to work around this issue.
If you want to camel marshal and unmarshal the data rightly, you can use JAXB data format directly, and you can set up other JAXB context options that you want.
Here is the example:
{code}
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="direct:marshal"/>
<marshal>
<jaxb prettyPrint="false" contextPath="org.apache.camel.example"
partClass="org.apache.camel.example.PurchaseOrder"
partNamespace="{http://example.camel.org/apache}po" />
</marshal>
<to uri="mock:marshal"/>
</route>
<route>
<from uri="direct:unmarshal"/>
<unmarshal>
<jaxb prettyPrint="false" contextPath="org.apache.camel.example"
partClass="org.apache.camel.example.Partial" />
</unmarshal>
<to uri="mock:unmarshal"/>
</route>
</camelContext>
{code}

> FallbackTypeConverter method throws JAXBException when marshalling nested, non-ObjectFactory, JAXB annotated, classes. These are classes that are annotated with the @XmlRootElement, but not generated using XJC, so there is no ObjectFactory class for them. The intention is to provide the package names containing the jaxb.index files to build the context.
> FallbackTypeConverter does not marshal or unmarshal using the package names, but rather uses the value's Class as the context. Thus everytime a JAXB annotated object contains another JAXB annotated object, there is an exception that looks like this:
