Guacamole Java Web application

[Simone Caronni]

Hello,

sorry for double posting to devel and java-devel but the last seems not so
crowded.

guacamole-common and guacamole-common-ext are now into rawhide and I've
been struggling a couple of days for the next parts.
I need some help with the guacamole-common-js [1][2]; the last step before
packaging the web application itself [3].

The build itself is normally generated with the command "maven package"; so
replacing it with "mvn-rpmbuild package" generates the following file.

How's the supposed guideline for packaging it? Where should I put the zip
file and how should the spec file be structured?
All the other java classes for Guacamole are into jars in
/usr/share/java/guacamole/.

I can't find any useful information for it in the Java packaging pages [4].
I tried to look at at least 20 java packages in fedora and could not find
one that was not packaging a jar file.

Warning: I know nothing about packaging a web app, so please take
all that I say with several grains of salt!  ;)

It seems that in the past there was some effort at standards for
packaging javascript libraries[1].  But even these do not seem to
cover your case, or at least not without you needing to patch the
upstream build extensively, and the guidelines effort seems to have
gone stale.

Maybe some others with more Guru-like qualities would have a different
opinion, but here is what I would do I think:

1. Patch the build to produce a .jar instead of .zip (with the same
contents; a .jar is not much more than .zip with different extension).

2. Install this .jar and related .pom as you normally would.

3. Patch the webapp itself if needed to find the .jar instead of .zip

This is assuming that the webapp needs to use maven to find this
dependency.  Maybe there is some better way.  Like put the zip in
%{_datadir}/%{name} and configure the webapp build to find it there?
Or, maybe the %add_maven_depmap macro can somehow be coaxed into
mapping to the .zip in %{_datadir} and no renaming necessary?  Just
trying to throw out some ideas.

Good luck, hope this helps, or at least does not harm!!

Hello,

thank you very much for your input. I used the packaging draft
guidelines you pointed out, as I'm thinking of asking FPC for a review
of the packaging drafts for javascript and web applications.

I filed the review here, it is a simple rpm containing 6 Java scripts:

https://bugzilla.redhat.com/show_bug.cgi?id=831975

This is the only prerequisite I miss for the main Guacamole Web Application!
Will you take it for review?

Thanks,
--Simone

Hi Simone,

Sorry for slow reply, I had a few days away from keyboard ;)

(and then a few really busy days to make up for it!)

I would be happy to review this final piece for you, but won't get
to it until next week.

cheers,
jon

No problem, thank you very much for the reply.
I will try to post the main Java Web application for review tomorrow
and make 831975 a blocker for it.

As packaging Java web apps in Fedora is still rough [1] I don't know
with what I will come out :D
