[Mifos-developer] Executable WAR: java -jar mifos.war (MIFOS-4919)
Michael Vorburger
I've started looking into an "Executable WAR" (java -jar mifos.war) for Mifos.
If you want to follow analysis & development, please watch
https://mifosforge.jira.com/browse/MIFOS-4919.
If you think this is an utter waste of my time, shout STOP! ;-)
Comments welcome.
Regards,
Michael

I think this is interesting and useful!
I also think that getting a war to run is *not* the trickiest part
of starting up Mifos. Most folks are able to download & unzip an
app server, grab a Mifos war, and throw it in the right place.
And the log messages from Jetty and Tomcat are pretty clear if
and why a war doesn't run. But "java -jar mifos.war" would totally
make it foolproof to run the war.
Something else I see as a blocker for many, many folks: connecting to
the database. All of us have run into this at some time or other.
Mifos assumes a database is present, and crashes horribly if it is not.
Wouldn't it be awesome if, instead, a Web page would come up that
would *immediately* say "hey, I can't see the database!" and would
force you to
1. change database settings right there
2. test the connection
3. fix/create your local.properties file (or at least display what
should go into MIFOS_CONF/local.properties)
and *then* start Mifos?
Heck, why can't we have both the war shortcut and the db helper? :)

Michael Vorburger
thanks for the interest! I'll make sure to keep the list informed as I
progress (slowly, few nights here and there).
Adam, re. DB set-up, what if we were even more ambitious... not only
simplify connecting to the database, but actually doing away with the
need for an external DB download/install/config?! Have a look at
http://mifosforge.jira.com/browse/MIFOS-4926 ...
http://dev.mysql.com/downloads/connector/mxj/ ... looks interesting to
me.
Ed or anybody, do we have any contacts in the openMRS dev community? I
have a suspicion that they are actually using exactly this approach
I've (independently) stumbled upon, because Googling for MXJ on Maven
I've (by chance) found their
https://tickets.openmrs.org/browse/TRUNK-2149... I'd love to contact
them e.g. by leaving a comment on that issue and pointing them to
http://mifosforge.jira.com/browse/MIFOS-4927, may be we could join
forces to get MXJ to Maven Central - but unfortunately their JIRA is
locked down and self service account creation is disabled. They may
also have thoughts re. http://mifosforge.jira.com/browse/MIFOS-4928 ?
Best,
Michael

Nod. You can't combine them at a low-level (ie: compile them together or
embed MySQL in Mifos and call it "Mifos") since the licenses are
incompatible.
Someone *could* create a Mifos "distribution", including Java, Mifos,
the stand-alone MySQL server, Pentaho, and a Tomcat or Jetty application
server. You'd have to pick an architecture and operating system, and
maintenance of this distribution is also a bit tedious.

Ed Cable just pointed out this out to me via direct email: "OpenMRS
<https://wiki.openmrs.org/display/docs/Running+as+a+Standalone+Application>
hasn't fully thought through that yet but they weren't too concerned
because of this FOSS exception:
http://www.mysql.com/about/legal/licensing/foss-exception/".
I had not found that page when I looked into the matter earlier.
Indeed this "FOSS License Exception" appears to confirm that we
actually *ARE* legally be allowed to use (embed) Oracle's MySQL ...
"MySQL Connectors" including the
http://dev.mysql.com/downloads/connector/mxj/ 'MySQL Connector/MXJ' in
question here into Mifos!
If anybody has strong objections, please speak now. Otherwise I'll
assume "approval", and (time permitting!) look into
http://mifosforge.jira.com/browse/MIFOS-4926. First I'd need to get
http://mifosforge.jira.com/browse/MIFOS-4919 done anyways. If anybody
wants to take over / actively collaborate on either, please contact
me...

falls under the FOSS license exception. I couldn't find anything
online that said for sure either way. I'll share my findings.
One thing I notice is that the Connector/MXJ is about 200M in a
.tgz. So, add that to the existing download. Kinda big, but probably
still reasonable with today's disk space and bandwidth. Especially
given the added ease in configuration/installation. Can't put a
price on that. :)

Hi Adam.
I saw you emailed our Sales Support alias and had a question.
Does Connector/MXJ fall under the FOSS license exception?
Here is a link that should answer most of your questions.
http://www.mysql.com/about/legal/licensing/foss-exception/
Strictly speaking Connectors do not qualify for FOSS exception:
The FOSS License Exception does not apply to Oracle’s MySQL dat! abase server or any Oracle or MySQL software other than the GPL-licensed MySQL Client Libraries.
Hopefully this helps. Please let me know if you have any questions.

the mySQL GPL licensing mess apart for now, I've recently spent 2-3
nights moving forward with MIFOS-4919 for an "executable WAR" (java
-jar mifos.war) anyways - let's deal with the DB separately in another
JIRA such as MIFOS-4926 or MIFOS-4921 later, and finish up MIFOS-4919
first.
The hudsonBuild-MIFOS-4919_ExecutableWAR-Squashed branch has my
proposal for this - please review using e.g.
http://mifos.git.sourceforge.net/git/gitweb.cgi?p=mifos/head;a=commitdiff;h=10260c483837f5c26f96f7e4faba7042c33b076e
if interested.
Trouble is, and what I need help with: New
MifosPackagedWARBasicTest.testPackagedWARStartup works locally for me,
but fails on Hudson - because it can't find the DB. Adam confirmed
that there is indeed a ~hudson/.mifos/local.properties on birch - does
anybody have any idea why the "normal" (integration/acceptance) tests
that use the DB all pass on Hudson, but my new ones doesn't? Do they
do something special to configure DB? I'm confused.
Actually something more general seems very wrong with
https://ci.mifos.org/hudson/job/head-hudsonBuild/ - the
MifosPackagedWARBasicTest.testPackagedWARStartup should
SocketC...@0.0.0.0:4847 but instead uses port 7077 instead on
https://ci.mifos.org/hudson/job/head-hudsonBuild/1617/console - that
would happen if old code without my stuff was used... it's as if
Hudson got mixed up code and used from head while trying to build from
my branch? Indeed, while the head-master-commit installs to
/home/hudson/hudson-home/jobs/head-master-commit/workspace/.repository/,
the head-hudsonBuild installs directly to /home/hudson/.m2/repository/
- that can't be right?!
Best,
Michael

My "Executable WAR" stuff is, hopefully, finally finished and ready
for merge into master - now including actually working tests (don't
ask why it took forever).
Please code review proposed final patch on
hudsonBuild-MIFOS-4919_ExecutableWAR-Squashed2
(http://mifos.git.sourceforge.net/git/gitweb.cgi?p=mifos/head;a=commitdiff;h=9a171b4dcd11b98eadac985382a5a84e07de5fb0)
and shout if you have any issues with this approach - actually even
better go right ahead and fix what you don't like on that branch if
you like - no offense taken. Without hearing anything from anybody,
I'll merge it into master in let's say... one week?
Here is how it works: If you build that branch, you'll find that the
war/ module now packages two WAR files: the mifos-TEMP-nonexec.war
(which is the same as the one before), and the mifos-exec.war (81 MB
instead of the previous 76 MB; this mifos-exec.war is the ultimately
the final mifos.war artifact that gets deployed into Maven and bundled
in the mifos-${env.BUILD_TAG}.zip). For simplicity's sake and to avoid
any end-user confusion, I suggest that only that new one shall be
distributed as mifos.war, not two different ones. One could then start
Mifos, without requiring an external Jetty (or Tomcat 7.0), simply via
:
java -Xmx1024m -XX:MaxPermSize=256m -jar mifos.war 9090
The last (and only) CLI arg is the HTTP port. Configuration is "as
usual" (http://mifosforge.jira.com/wiki/display/MIFOS/Mifos+Configuration+Locations),
nothing changes about that with this approach.
The same mifos.war works, of course, still like a "normal" WAR that
can be deployed into a "classic" (non-embedded) external Jetty
container.
Best,
Michael
PS: I wish I had some smart idea how to avoid the -Xmx1024m
-XX:MaxPermSize=256m ... but short of forking another JVM or something
like that, addressing that leads into the launcher/installer
discussion; and I suggest we treat that as next step but separate
issue (closing MIFOS-4919 when the basic executable WAR is on master)
in a new thread - may be somebody else (student volunteer?) would like
to pick that up and build it on top of my contribution? C.f. our
earlier discussion on
http://groups.google.com/group/mifosdeveloper/browse_thread/thread/65a8a6ede5f8a953
... my personal favorite (now having the executable WAR) would
probably be the http://launch4j.sourceforge.net route there.

thanks to overwhelming responses (none) from everybody ;-) on my post
requesting review 2 weeks ago, I've just now finally merged this to
master, and propose to close
http://mifosforge.jira.com/browse/MIFOS-4919.
Usage as explained in previous post - let me know if any doc on Wiki
or INSTALL or anything would be needed, and if any of you would be
willing to create that?
Best,
Michael
PS: Now next on with http://mifosforge.jira.com/browse/MIFOS-5157 (any
volunteers to help with that?), and
http://mifosforge.jira.com/browse/MIFOS-4926 (I'm still hoping the
legal question surrounding MXJ can be solved; waiting for a response
from somebody).

Dear Michael & Ed,
Where is doc? May be I am looking to wrong place?
We need Mifos Installation Manual based on Jetty for beginners ( like it is for Tomcat on web site). If manual and installation process will be well organized (clear enough) then it is not a big benefit from EXE. (especially if it will make update process more difficult). Once again accept apologies , I am not a programmer and may misunderstood something.
