freemarker with pojo and/or xpath

[paulc8712 <pa...@gmail.com>]

Hi All.

I'm fairly new to Camel - and very new to Freemarker.

There doesn't seem to be much out there in the way of camel-freemarker
examples other than the fairly simplistic email example in
http://camel.apache.org/freemarker.html

What I would like to be able to do is use freemarker with either a POJO
header or body, or XML using xpath.  Is this possible?

If it is - I would appreciate it greatly if people could share some sample
freemarker templates that use POJO as the data source.

Thanks, Paulc

For Freemarker itself the manual is on http://freemarker.org/docs/

Re: freemarker with pojo and/or xpath

Yep, totally possible.
So freemarker binds a "context" to the template, and populates the template
body with whatever is found in the "context"
So in the case of Camel integration, Camel will put some parts of the
exchange (and the whole exchange actually) which is then available in the
freemarker template.
The body and headers are all treated as POJOs when they are bound to the
freemarker context, so if you have your own pojo, MyPerson, and you wish
you access its members 'givenName' or 'familyName' within the freemarker
template, you can do so like ${body.givenName} or ${body.familyName}. Same
thing goes for headers.

Have a peek at this unit test to make it more clear:
