If it's any use, my InnoSetup file is here -
https://github.com/praxis-live/praxis-live/blob/master/resources/pl-installer.iss.template
 It's fairly simple, really, and could do more, but does the job.  I
only recently stopped running this manually and templated it for use
with Ant - only replaces ${app.version}

Should be easy enough to adapt and experiment with.  It's more
flexible more easily than the NetBeans installer, and handles things
like in-place upgrades and shortcut icons much more simply.  But the
primary benefit is not having to rely on the embedded JRE to run.  In
fact, I did start looking at the possibility of a NetBeans IDE
installer with it that could offer to download the JDK as part of the
installation process.

Looks great!  My own first degree (some time ago) was in music, and I
can think of at least one other person around here who should
appreciate a jazz application on NetBeans platform! :-)

Reminds me a little of Frinika, which at one point had a fork on to
NetBeans RCP.  And there's also Blue of course.

I'd be very interested to hear more about the underlying architecture
in use - I write / maintain a variety of audio and media Java
libraries as well.

In this case wouldn't there be a need for a netbeans GUI based option to 
bundle a JDK/JRE for each OS installer by default without manual 
modifying the build.xml and so on.

 Thanks all for your feedback.
I checked the new Oracle license : I understood that I can use JRE on my own 
computer, but I can NOT bundle it and redistribute it. 

So I have the following choices:
1/ bundle a JRE and it must be OpenJDKor
2/ have the installer check if a JRE is there, and if not, ask user to install 
a JRE on its own (then he can choose Oracle or whatever). I assume that after 
JRE installation my Netbeans app will automatically find this JRE ? 


InnoSetup is probably be a good idea: I guess it's more powerful and flexible 
than Netbeans installers, but I'm concerned by the time needed to learn yet 
another topic... Does InnoSetup simplifies the "installer signing" ?

Are you using Ant or Maven? PraxisLIVE has an Ant target to build an
installer with InnoSetup and a bundled JDK. Personally I'd l recommend that
approach over NetBeans installer if bundling.

Eg. https://github.com/praxis-live/praxis-live/blob/master/build.xml#L70

Interested in seeing your application!

Well, you could have installation instructions initially explaining how and
where to get the JRE from and where to reference it in the conf file of the
app for your initial release.

 I can’t speak for general users, but in enterprises you can’t assume Java - 
much less an ancient one like 7.   I don’t even think that’s available for 
download anymore, is it?  If that’s all you’ve tested with, i think you’d have 
to include it with your installation.
Just my opinion, of course.tom

Hello,
I develop in my spare time a Netbeans platform music application targeted at 
individual musicians (professional or amateur). The application is based on 
NB11/Java7. I test it on Win10(x64) and on a Linux Mint distribution, though I 
expect most of the users will be on Windows. At the beginning I won't release a 
Mac version.

In a few weeks I will put it online for the first time, and I'm interested to 
get recommendations from experienced people regarding possible 
installation/configuration problems on user machines.

For example is it realistic to assume that most users will have Oracle JRE7 
already installed ? Is it better to embed a JRE in my download package ? etc.

ThanksJerome

Especially for non technical users you can assume they will have no Java so
you must include a JRE. I recommend AdoptOpenJDK 11.

Signed installers would be nice if you don't want Windows to scare away
your users.
