[virgo-dev] [snaps] Support for listeners in snaps

[Dmitry Sklyut <dmitry@xxxxxxxxxxx>]

Hi All,

I have a need or more like desire to register context and request listeners in a snap (1 and 2) web.xml.  NOTE: listeners work just find in the host app.

So I started looking at the code base to see how it can be implemented.

From my limited research, I could only come up with a way to do it by including a tomcat context.xml (3) to plugin into web.xml parsing and request processing pipeline by basically overriding a starting valve.

Does anyone have any other thoughts around using listeners in snaps?  Different approaches that do not involve container specific extensions?

Regards,
Dmitry
