Templating without a SlingRequest

[Hakim Sadikali <ha...@contentthread.com>]

Hi,

Is it possible to dispatch/include a templating file (HTL/JSP) from within
an OSGi service?

Here is the use-case:

1. Nightly schedule job that finds all resources that have expired
2. Create an email with the content of the resources (title/path/links etc)
3. Send the email to a user for them to act on it.

You could easily create a static email and then build on top of that, but
since sling is already a templating engine it would be great if you could
leverage that to generate the email by invoking a script with the
parameters passed in. I believe earlier versions of the Health Check had
something similar setup.

Hi,
Yes, this is possible via the SlingRequestProcessor service[1]. You need to
construct "fake" request and response objects which provide the information
needed to execute the script/servlet. You can use [2] for these
request/response objects or roll your own.

Justin
