Generating email from template outside request/response cycle
Hello-
I'm attempting to use the Wicket 6 email templating mechanism to render an
HTML email from a Panel OUTSIDE the normal request/response cycle -- in a
timer thread. I have already been successful generating email from within a
normal request by following the examples at
http://www.wicket-library.com/wicket-examples/mailtemplate/
The timer thread periodically checks the database for a particular situation
and, if the requirements are met, an email is generated.
I have searched in vain in this forum for a solution. Two main problems I am
running into are:
- Getting the error message "There is no application attached to current
thread"
- Using @SpringBean does not work outside the Wicket context. This is true
even if I start the time thread within Application.init()
I'd prefer to generate the email from a Panel as I already have those in
place but would definitely be willing to do so from a page.
Thanks!

Hi,
You can export the Application as thread local manually.
See for example:
https://github.com/apache/wicket/blob/442932d4e4c5cc27940bc2ef956cb24c1ba54df0/wicket-experimental/wicket-native-websocket/wicket-native-websocket-core/src/main/java/org/apache/wicket/protocol/ws/api/AbstractWebSocketProcessor.java#L200
Make sure you reset it to null at the end.

Derived from Wicket's ComponentRender class:
https://bitbucket.org/shadders/wicket-el/src/a41127f0771a4b792255cfc0c2ec47c500db1b1b/src/main/java/com/shadworld/wicket/render/Renderer.java?at=default
Not sure if it will solve the SpringBean problem but it it will work
outside a wicket application.
Renderer.init();
CharSequence html = Renderer.renderComponent(myPanel);
