Hi Willem,

yes, I installed the camel-jaxb feature.
This route run in a pure camel project.

Thank you for looking into my problem.

Cheers,

Christian,

If you use the unmarshal instead of the convertBodyTo then I would assume it should work in OSGi as well.

Hi Christian,

I did a quick fix for the error to Apache Camel repository, but it will take some time to sync the apache change to fuse.

I will keep you posted when the fix snapshot comes out.

Hi Willem,

it's not critical for me, but I still received the warning

Hi Christian

It looks the Camel doesn't find a way to turn a File object into an InputStream object.
Can you try to add below line to convert the message body into InputStream?

.convertBodyTo(InputStream.class)

Hi Willem,

if I changed 'convertBodyTo(Matrics.class)' to 'convertBodyTo(InputStream.class)', I received the following log entry:

11:19:21,003 | INFO | Component@689490 | FileEventReader | ps4b.rfid.file.FileEventReader$1 24 | received body of type: class org.apache.camel.converter.stream.InputStreamCache

Hi,

Your route rule could be like this

from("file:/Applications/apache-servicemix-4.1.0.0-fuse/incomingEvents/")
.convertBodyTo(InputStream.class)
.convertBodyTo(Matrics.class)

Just make sure the JAXB converter get the right message body type.

Hi Willem,

if the route rule looks like this

from("file:/Applications/apache-servicemix-4.1.0.0-fuse/incomingEvents/")
.convertBodyTo(InputStream.class)
.convertBodyTo(Matrics.class)

I receive the following log entries:

The JAXB converter could not be called...

Hi

Could you try upgrading to latest SNAPSHOT release of FUSR MR? We did a fix recently on discovery of type converters in 3rd party bundles when running in OSGi.

The maven repo is here:

Hello Claus,

What did you mean exactly, with "upgrading to latest SNAPSHOT release of FUSR MR"?
Install the latest SNAPSHOT version of FUSE ESB or update some OSGI/JBI Bundles?

Upgrade all the camel-xxxx bundles from version
1.6.0.0-fuse
to
1.x-fuse-SNAPSHOT

The next release FUSE MR release 1.6.0.2 should contain this fix. The last release 1.6.0.1 does not.

Hi Claus,

I upgrade all installed camel-xxx bundles:

camel-core (1.0.0.x-fuse-SNAPSHOT)
camel-osgi (1.0.0.x-fuse-SNAPSHOT)
camel-spring (1.0.0.x-fuse-SNAPSHOT)
camel-jaxb (1.0.0.x-fuse-SNAPSHOT)

but I still receive the warning and the body is not converted:

12:40:29,707 | WARN | Component@eb5cdc | ConvertBodyProcessor             | l.processor.ConvertBodyProcessor   46 | Could not convert body of IN message: FileMessage: D:\tmp\inbox\sample_event.xml to type: de.ps4b.rfid.model.matrics.Matrics

I tried both variants

.from("...")
.convertBodyTo(InputStream.class)
.convertBodyTo(Matrics.class)
.process(
   ...
)
.to("..")

and

.from("...")
.convertBodyTo(Matrics.class)
.process(
   ...
)
.to("..")

Cheers,
Christian

JAXB can also be used as a data format. Try that instead of the dual convert body to.
