Rack, Warbler and servlet filter behavior

Ruby JRuby
1

Hi,

I’m trying to get my rack app to run as a true servlet filter within
another
java web app. I’ve got it running fine as a standalone servlet handler
(basically the same web.xml file that warbler created). Is it possible
to
run an embedded rack app and still be able to do something for each
request
(like a servlet filter)?

Thanks,

Matt

Try the new Go Web Framework at http://www.tudbc.org/goweb which
allows you to run Ruby natively inside a Java EE Server, and you still
have full access to the Java EE Server.

The only problem is that this is an existing, tomcat-deployed app. I
can’t
change that aspect unfortunately. But Go looks pretty interesting.
Thanks,

Hi Nick,

I mean #1, run a Rack app as a filter of some sort. Is this something
that
might be possible in the future?

Thanks,
Matt

Do you mean use a Rack application as a servlet filter? Or just run
other servlet filters in front of your Rack-based application? For the
former, it’s not possible today without some modifications to
JRuby-Rack. For the latter, it should work fine as long as you pay
attention to ordering of the filters.
