Custom context-param config for web.xml in Warbler

pletisan · August 29, 2008, 7:48pm

Hi there,

Has anyone successfully configured custom context parameters in
web.xml via config/warbler.rb?

I tried:

config.webxml.foo.bar.baz = “something”

as well as

config.webxml.context_params[‘foo.bar.baz’] = “something”

but both of them seem to be ignored.

I can edit config/web.xml.erb if I really have to, but it would be
cleaner if I could use warbler.rb for this.

Anyone had better luck with this?

I’m using warbler 0.9.10

thanks,
Igor

I’ve done these:

Value of RAILS_ENV for the webapp

config.webxml.rails.env = ‘production’

Application booter to use, one of :rack, :rails, or :merb. (Default

:rails)
config.webxml.booter = :merb

successfully for a Merb app. But I don’t think that they actually
cause changes to the web.xml file itself.

For customizations to the web.xml file, I created a config/web.xml file
and that gets copied into the tmp/war/config directory when you warble.

I have tests that ensure custom context parameters are possible.
You’re not seeing anything rendered into the resulting web.xml? Are
you sure you don’t have an old web.xml.erb or pluginized warbler lying
around somewhere?

Hi Nick,

You are right, it works in some cases:

config.webxml.foo.bar.baz = ‘something’ —
OK
config.webxml.context_params[‘foo.bbb.bz’] = ‘something’
---- doesn’t work
config.webxml.context_params[‘com.’] = ‘something’
---- doesn’t work
config.webxml.com. = ‘something’
---- error below

rake aborted!
wrong number of arguments (1 for 0)
/usr/local/jruby/jruby-1.1.3/lib/ruby/site_ruby/1.8/builtin/
javasupport/java.rb:42:in method_missing' (eval):80:in initialize’

The property I’m trying to set is com.. and
currently I can’t find a way to do that via warbler.rb

my warbler.rb and web.xml.erb are up to date and there are no older
versions in my project.

What is the exact value of ? You might be running into
an odd method name collision issue with OpenStruct.

It looks like it can be really anything:

sun -> com.sun
sun.dse.timeoutproxy -> com.sun.dse.timeoutproxy
foo -> com.foo
…

#context_params is meant to be a read-only helper, not for assignment.

Do the specs run for you? Can you write a new failing spec
demonstrating the problem?

Aha, it’s java integration getting in the way here. How can I disable
that method_missing for OpenStruct?

I explicitly undef the %w(java javax com org) methods in trunk, plus I
added square-bracket accessors to work around future name collisions.

They’ll be in the next release, due soon.

Something like that…
