AW: Error sending email from Camel application
Hi Charles,
I'm not sure if I can help you out, but a couple of days ago I had an error
with sending multiple REST requests to a remote server. I aggregated the
responses values of each request in a complicated Map of Map of Maps structure
that resided in the Camel header. After a couple of requests, the http
handshake threw an exception. After some debugging I figured out: Camel uses
the complete Camel Header to setup the http header. So the toString() result of
my Map of Map of Maps went into the http request as a header, and that grew too
large. What helped me out was to implement a custom headerFilterStrategy in
which I managed to keep all of my custom header values out of the way.
Maybe this will help you...
Regards,
Christian

Betreff: Re: Error sending email from Camel application
The route is taking properties from a POJO and building up a message to use to
send an email. I add the from, to & subject headers in the route which are
just string values. The message body is created using a Velocity template
which extracts some values from the POJO.
I included some tracers in the route and here is the info that is logged by
Camel immediately before calling the SMTP endpoint (I've anonymised some of the
data):

Re: Error sending email from Camel application
Looks like I've managed to fix this, with some help from this post on
StackOverflow:
https://stackoverflow.com/questions/33397359/how-to-configure-jackson-objectmapper-for-camel-in-spring-boot
What I did is to create a new ObjectMapper instance and disabled the
SerializationFeature.FAIL_ON_EMPTY_BEANS feature:
private static ObjectMapper getCustomObjectMapper() {
ObjectMapper om = new ObjectMapper();
om.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);
return om;
}
I then added this instance to the JNDI registry using the name "json-jackson":
registry.bind("json-jackson", getCustomObjectMapper());
This code is executed in the CameContextLifecycle.beforeStart method.
I also had to modify the Content-Type of the request to text/plain so
that the message text was included in the email body rather than as an
attachment.

The message suggests that I should disable
SerializationFeature.FAIL_ON_EMPTY_BEANS but I'm not sure how to
achieve that. I'm researching that just now and I was looking at
doing something like this:
JacksonDataFormat df = new JacksonDataFormat(java.util.Vector.class);
df.disableFeature(SerializationFeature.FAIL_ON_EMPTY_BEANS);
in beforeStart method of my CamelContextLifecycle class.
Re: Error sending email from Camel application
Hi
>From the stacktrace it seems its some kind of header that is causing
this jackson conversion as its .toString method is called.
What objects do you store in the headers? Maybe use tracer, or debug
your Camel application and see which header has the problem.

Error sending email from Camel application
Hi,
I have the following route in my application which sends an email
based on a template filled out with data from the SingleImageModel
class:
from(ACTIVEMQ_EMAIL_QUEUE)
.routeId(ROUTE_EMAIL_NOTIFICATIONS)
.convertBodyTo(SingleImageModel.class)
// set subject, from address & to address
.setHeader("subject", constant(EMAIL_SUBJECT))
.setHeader("to", simple("${body.email}"))
.setHeader("from", constant(EMAIL_FROM))
// format the message body
.to(VELOCITY_EMAIL)
.log("${body}")
// send email
.to(SMTP_URL)
.end();
When it tries to execute the SMTP step the message fails with the
following error:
2017-12-21 17:30:08,034 []
