will you also use the part of the interface, that would allow the user to accept the terms
and conditions in Eclipse? It may look better if you do.

Subject: $0 subscription downloads - Stacks integration with download manager
Rafael (and others):
So I spent an hour or so yesterday chatting with David Hladky about the
new download manager rest services which JBosstools intends to use to
help us download EAP 6.x. It allows for a workflow that can help us get
terms and conditions, verify credentials, verify agreements have been
signed, and then provide a download utility with a temporary url that
expires to download the EAP.
The api and the test server I played with look good so far. JBossTools,
though, pulls all of its runtime information from jdf-stacks. We
typically pull our download urls from there.
Currently in stacks, community editions have a "url" for the project
page, and a "downloadUrl" for a link to a permanent url for the given
runtime to download.
EAP instances in stacks.yaml only have a url for a project page. When
the download manager written by David goes live, we'll need to consider
what to do for stacks.yaml, and I'd prefer to get this stuff sorted now.
I'd like to suggest that we add a new attribute "downloadManagerUrl".
This will ensure clients know that this is a workflow url and not a
static url for downloading a file.
There's 2 parts to the rest service written by David. First is the rest
service url itself, and the second is the file we're requesting.
Currently a url for one part of the rest workflow (in this example, to
get terms and conditions) looks like this:
You can see the two parts are the rest service url (on test server,
) and the second part
is what we're requesting (in this case,
I see a few problems here. The first is that, in my opinion, those urls
are pretty long to be including in stacks.yaml... but luckily the
download-manager allows for shortened urls, so we could have the
download-manager server respond to a url like
The download manager would then map the attribute to the
/content/blah/blah/sha path and proceed accordingly. So this is easily
The second, is that the rest services do not point to the next url to
request. For example, if I go to the tc-accepted rest service to see if
the terms and conditions were accepted yet, it does not point me to the
next url in the workflow. Because of this, there's really no single
entry-point in the workflow, and each rest service url is kind of a
With the second point in mind, we might just want our stacks.yaml
attribute to say downloadManagerPath=jboss-eap-6.0.0.dv.ci-installer.jar.
The client (in this case jbosstools) would pass that string to the
download manager rest service it chooses to use. The download-manager
server would resolve jboss-eap-6.0.0.dv.ci-installer.jar to its more
specific /content/sha256/23423823423/etc path, and proceed normally.
One concern with this approach is that the stacks.yaml will never
include the actual url of the rest service entry point. Even if we
wanted to have stacks.yaml point to the entry point, there's no one
entry-point since the rest services do not point to the next step in the
I personally have no problem using the service as it's written now, and
with stacks.yaml only having a shortened path available, but I wanted to
get your (and others) feedback on the situation before this gets pushed
to production, after which we probably won't have much chance to change it.
