Hi,
I am trying to get my JPA entity classes to work with camel, but ran into a
problem. One one the fields is a compressed string, and I use
a org.eclipse.persistence.mappings.converters.Converter on my entity to
automatically convert it like this:
@Basic
@Column(name = "XML_Data")
@Converter(converterClass = CompressedStringConverter.class, name =
"CompressedStringConverter")
@Convert("CompressedStringConverter")
private String xmlData;
The conversion works OK in my other unit tests. But when I use it inside a
camelcontext using either a bean or jpa component, the entity manager throws
this error at me.

This looks like a classloader problem to me, because
the CompressedStringConverter really does
implement org.eclipse.persistence.mappings.converters.Converter.
Has anyone noticed something similar with camel?
