One of the very useful features in previous JBoss AS versions was the
ability of the server to identify and pick up changes to a .jsp page in
an exploded deployment and serve the updated content on next request.
Trying this out in JBoss AS 7.0.0.Beta3, I see that this no longer works:
1) Create and deploy a test.war (along with a test.war.dodeploy) in the
standalone/deployments.
2) test.war contains a test.jsp with an intentional syntax error in it
3) Access the jsp via browser and see the (expected) compilation error.
Now open the test.jsp file in a text editor, from the exploded test.war
deployment, and edit it to fix the error
4) Access the jsp via browser again. Tried it more than once. I still
see the compilation failure i.e. the jsp changes aren't being picked up
anymore. I had to undeploy and redeploy the exploded deployment for the
changes to be picked up.
I remember that in previous versions of AS there were some parameters
for the jsp compiler/executor which by default enabled this check for
jsp changes. Has this changed in AS7? Where and what values are set
currently? Or has this got something to do with the way we handle
exploded deployment in AS7?

Well, you have to enable either development mode, or the background
check for recompilation :)

IMO, before going to production with the server, any developer/team
would go through a development phase in which he would definitely like
this feature. So having this turned on by default (atleast in standalone

(My reply here isn't really specific to this issue but more towards the
changes that we do in AS7)
I do realize that AS7 is drastically different from previous versions
and we are trying to do our best to get it right. At the same time, I'm
sure many of us realize that, for various reasons from a user/developer
point of view, migrating to AS7 isn't going to be a straightforward
task. So I think, wherever possible (like this case), we should make it
easier for users to feel at home while using AS7 instead of adding to
their learning list yet another server specific configuration.

Well, everything can be easily updated, like static files, and there are
plenty of dynamic pages tech out there. JSP is actually not dynamic
because it uses compilation, although this is hidden, they are actually
servlets with a small runtime.
There are plenty of possibilities for you:
- Make your updates in place, then add a .dodeploy. That's more robust
(it allows classes changes), and still far faster to use an exploded
deployment.
- Add the development mode in the JSP config if you're working with
exploded deployments, and anticipate only JSP updates. Sorry, but this
is a rather specific situation right now, it's no longer 2001.

The dev scenario I described using a marker (or the equivalent API call
to trigger a redeploy) seems far more sustainable, even if it takes a
bit more time (framework init, etc).

JSP is a bit specific, and I explained why.
Hopefully. Development mode for JSPs is a relic of the past, deprecated
if you prefer. So it is enabled back using a flag, for the folks that
were really in love with it back then, and still use straight JSPs. This
flag is JSP specific. Looking at your new email: facelets are not JSPs.

It is called "development" because that's the name of the init-param
that has been used by the Jasper servlet, starting in 1999. Other
subsystems will likely not have a dev flag. As it is in the
jsp-configuration portion, I think it should be obvious this is JSP
specific.

As we do today, I am thinking you need to have configs out of the box that can be

Production
Development
Maybe even JMS

or....
I think prepackaged tested configs are a good idea as one size will not fit all. We have
done this for a long time and am wondering out loud why that notion would be removed?

The default for JSF is production mode. JSF actually has four modes,
"Development", "UnitTest", "SystemTest", and
"Production". But
"Development" and "Production" are the only ones used by the JSF impl.
Usually, the developer would set this as a context param in web.xml.
It can also be set via JNDI.
As I was pointing out earlier, Development mode for JSF Facelets xhtml
files acts like JSP. We need to support exploded deployment to make
it worthwhile.

Name is fine, problem is configuration + default
Other
subsystems will likely not have a dev flag.
This is where I am not that sure, portal will need one, we already have
such a flag to not cache built resources. I'm sure some other parts will
also want to make a distinction.
As it is in the
jsp-configuration portion, I think it should be obvious this is JSP
specific.
It is obvious, it's not the problem. The problem is to be user friendly.
I don't want to tell my users that to be able to do quick turnaround
development they have to:
- enable the JSP development flag...
- enable the GateIn development flag...
- enable the xyz development flag...
It's good to be able to "fine-tune" but would be nice to share a flag
too IMO.

There is a requirement in the PRD to have a development configuration and a production
configuration, but that is specific to EAP. Traditionally, we have made the AS
distribution more "development" focused out-of-the-box.
I'm not sure, in this specific case what is the best option, but EAP will have a
production and development configuration (perhaps a script that sets things up for either
using the management API).

This is where I am not that sure, portal will need one, we already have
such a flag to not cache built resources. I'm sure some other parts will
also want to make a distinction.

It is obvious, it's not the problem. The problem is to be user friendly.
I don't want to tell my users that to be able to do quick turnaround
development they have to:
- enable the JSP development flag...
- enable the GateIn development flag...
- enable the xyz development flag...
It's good to be able to "fine-tune" but would be nice to share a flag
too IMO.
It shouldn't be a global setting at all. It should be per-deployment
and it should default to "on" when there is exploded content and "off"
otherwise. In other words: the user should never even need to know
about it.

Andy,
So if AS 7 is more development focused, I agree it can/should be, can any and all
decisions made/discussed/etc on this list, make that experience the best it can be.
Worrisome threads in the last week:
Should a welcome page exist
Should it be enabled to have a .jsp to be hot deployed
How should lifecyles of datasource deployments be
"configured/monitored/changed"
On a side vein I still worry about adoption and the learning curve of all of this new
amazing stuff.
Probably a few others, but those have been on my mind this week.

My two cents,
As we do today, I am thinking you need to have configs out of the box that can be
started.
Production
Development
Maybe even JMS
or WS
or....
I think prepackaged tested configs are a good idea as one size will not fit all. We have
done this for a long time and am wondering out loud why that notion would be removed?
There is a requirement in the PRD to have a development configuration and a production
configuration, but that is specific to EAP. Traditionally, we have made the AS
distribution more "development" focused out-of-the-box.
I'm not sure, in this specific case what is the best option, but EAP will have a
production and development configuration (perhaps a script that sets things up for either
using the management API).

I'm not a customer, per se, but I do use JBoss for a few of my
production deployments.
I'm loving AS7. I'm a dev and an admin, and there's compelling stuff
going on in both those areas.
As far as the "default to development" or "default to production"
debate, I say (not that it matters) default to bare bones production,
and provide configs for various scenarios (similar to previous
releases, but with a bit more variety perhaps).
I'd rather have security out of the box, than comfort.
I'm not advocating no docs and hard to find configuration parameters,
by any means. I just think putting things in a less-than-secure (and
slower) mode should be the onus of the developer/end user, vs. coming
that way out of the box.
I acknowledge that I'm probably in the minority here, but especially
with a release as blazingly fast as AS7 currently is, it'd be a shame
to hide that away by default.
What's the "image" for AS7? Like, it's been pretty enterprise-y, but
it sounds like there's a move towards "Hey, it's for everybody!" type
of deal.
If I'm some random JEE guy, I'll probably be all like, "it's that much
faster, really? I'm gonna drop my WAR (is that like, soo 2004? ;]) in
there and see!", but I dunno what the target demographic is. People
new to JEE?, people new to AS7?, Developers?, Admins?, people X? What
are the main targets with AS7? "All of them" is swell, but hard to do
well. =)
I applaud the effort at "all of 'em". It is doable, IMHO. But I *am*
an optimist (mostly).

The dev scenario I described using a marker (or the equivalent API call
to trigger a redeploy) seems far more sustainable, even if it takes a
bit more time (framework init, etc).
Application developers do not care about sustainability. They care about turnaround and
development time.
Operations guys care about sustainability.

I will never allow this change to go in.
I read this entire thread again to try and understand why this is being
opposed. I see a couple of reasons, none of which I understand:
1) One of the reasons being mentioned is that enabling the option to
detect runtime .jsp changes breaks the TCK/spec. However, I don't know
what exactly this breaks? Can someone tell me what that is? If it breaks
some spec compliance then the rest of my arguments are irrelevant and
I'll stop asking for this flag to be enabled.
2) Enabling the option to detect runtime .jsp changes is bad for
performance. The suggested workaround is to redeploy the application,
which really doesn't make sense because that's worst if we are talking
about a developer's productivity. It's already been mentioned that the
community edition of JBoss AS is meant for developers and is _not_ meant
for direct production use. A application has to go through numerous
development lifecycles before it makes it to production (I didn't want
to state the obvious, but...).
Ultimately, this flag directly affects the end users (application
developers) and I think we should atleast take their opinion into
account before deciding not to allow this change. I'm sure that even if
we ship this as disabled, out of the box, a vast majority of the users
will end up enabling this flag as a first step during the development
lifecycle of their application.
Just to reiterate, I don't mind disabling this flag by default, if
there's a real valid reason for that. So far, I haven't seen any.

Bad performance + different behavior = it won't get in.
Now, I would have some sympathy if JSP was not being singled out among
the equivalent technologies, which are all running in production mode,
because you happen to use that for you hack testing. So change the
configuration, move on with your work, and stop wasting both of our
time. Thanks.
I'm ok if someone proposes a "master" development flag BTW.

Bad performance + different behavior = it won't get in.
Now, I would have some sympathy if JSP was not being singled out among
the equivalent technologies, which are all running in production mode,
because you happen to use that for you hack testing. So change the
configuration, move on with your work, and stop wasting both of our
time. Thanks.
I'm ok if someone proposes a "master" development flag BTW.
I may be wrong, but I believe that JSP is singled out because every
other resource type (other than classes of course) already behaves this
way when you have an exploded deployment.

Has anyone measured what is the true overhead of enabling it by default, anyway?

Dev mode:
- leaks details about the JSP source to give info on where and why the
error occurred (that's insecure, but important for dev)
- wraps exceptions for the same reason (TCK will fail)
- uses more memory (bad)
- uses a little bit more CPU (very little, so not bad)
I could enable some background reloading with fewer side effects, but
without the error reporting, it wouldn't help developers much.
So the domain model is a nice configuration format, well documented
(hopefully), so I think people will be fine using it and should be able
to configure this dev mode if they need it.
