Hi Adam,
is it possible to see an example/demo of the newly added webslinger
feature in the actual OFBiz trunk ?

Yeah, go to /webslinger in your browser.  The files that drive that
are at framework/webslinger/websites/webslinger/www,
framework/webslinger/modules/ofbiz/www, and
framework/webslinger/modules/defaults.zip.

It's not a full-featured demo yet.  I've been slowly reimplementing
the things that webslinger supports, in a more proper fashion, as time
permits.

Hmm, cute.  I run with java 1.6, so hadn't noticed this.  I need to
add the concurrent.util backport, then this will automagically work(I
have a proxy factory creator.

Fixed in revision 753474.

Adrian,
unfortunately I got the same error as before.

What version of java are you running?

[Bruno Busco]

java version "1.5.0_14"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03)
Java HotSpot(TM) Client VM (build 1.5.0_14-b03, mixed mode, sharing)

Grumble.  webslinger test cases work with 1.5.0_16.  But it fails when
run inside ofbiz.  I've duplicated it here, stay tuned.

[Bruno Busco]

Thank you

Gah, this is an issue.  The concurrent backport doesn't actually
implement *any* java.util.concurrent interfaces that exist in 1.5 or
1.6, so you can't swap them around.  In otherwords, I never tested
this particular part of webslinger. :(

For now, running on java 1.6 will allow it to work, until I get this
fixed in a more permanent situation.  I won't require 1.6 yet, so this
is a show-stopper bug.
