Type converter for serialized object?
I'm working on an app that's using akka camel (the akka camel extension) to
send/receive JMS messages to/from another application that is using Spring
Integration.
In our first baby steps in integration testing we're getting the following
exception when trying to convert a message whose body is a serialized
instance of an application-specific class C via
camelMessage.getBodyAs(C.class, ctx):
Caught exception: org.apache.camel.NoTypeConversionAvailableException: No
type converter available to convert from type: byte[] to the required type:
C
I've verified that the camel message body is the serialized object of type
C as I can deserialize it into the object in separate test code that I
wrote to check that.
Do the default type converters that Camel uses not include one that can
deserialize a serialized object? If that's true, is there a type converter
that does this that I can include, or do I need to write a custom
converter? Aren't serialized objects as message bodies quite a common use
case?
thx,
Chris

Thanks Willem, that's exactly what I needed. I'm new to Camel and hadn't
realized there were multiple ways to do data transformation and had
prematurely found and tried to use type conversion.
I found this<http://stackoverflow.com/questions/14501119/which-camel-construct-is-suited-for-transforming>thread
on SO as well as chapter 3 and esp. table 3.1 in the Camel in Action
book were helpful in calling out the different options.

Hi,
Camel has a serialisation data format can do this kind of work.
