I don't want to build an application. I am a beginner, I want to learn,
I have a book for beginners where the examples are simple and supposed
to be runnable, but some of them are not. My question is very simple :
how the XML editor can be activated in a very simple project without
modules ? The method given in the book does not work, and the only help
I get here is "try disabling modules one by one until it works". OK, I
give up and I unsubscribe this list.

Don’t use the book like that. It is not there to follow step by step.
It is there as a guide to implement the application you want to build.
As you can see, what you’re doing doesn’t work. You can continue being
frustrated or use the book and the NetBeans Platform in the way
they’re meant to be used — especially if you’re putting an IDE
together, start with what there already is rather than developing from
scratch.
And with the book, ask yourself what it is you’re going to be
developing and then use the book to guide you with that.

The answer is very simple : I don't want to build an application,
I just want to follow the examples in the book step by step. You
suggested me to purchase this book and to read it carefully, that
is what I am doing.
In chapter 1, we are just testing the effect of selecting ide
modules in the library on a sample project built from scratch that
contains no module : activating the Image editor, activating the
Utilities module, etc... and seeing how menus are modified and haw
images can be edited. Using the sample code downloaded from the
link given in the book gives the same result as my project built
from scratch.
As I said in the previous mail, the approach that you suggest for
the XML editor is very long and not understandable for a beginner
: how can I guess which modules are not needed ? For most of them,
I have no idea of what they are doing ! I thought that at least
the error message could help in finding the missing modules, but
it does not help.
I was trying this approach for almost an hour but I could not
identify the missing modules.
OK, forget this mail, I give up with NB Platform.

The question is what it is you’re trying to achieve here. Given
what you’re trying to do right now, your approach could be
considered to be “wrong”, i.e., start by thinking of the larger
idea of the application you’re trying to build and the features
you need for that.
A better approach than building up an IDE from scratch, as you
seem to be doing, is to start from the full IDE and remove the
parts you don’t need. It’s the exact opposite to what you’re
doing, please consider it.

Thank you Geertjan
This is a simple exercise to look at the possibilities that
each ide module can give. I tried successfully the image
editor and the Utilities module, but it is clear that some
other ide modules need to be selected for the XML editor
since I can run with all ide modules selected.
But how can I find the missing modules ? Of course, I could
start with all ide modules selected and try to unselect one
module at each run until it fails, but it would take a very
long time. How the error message can help ?

Hello.
Running Netbeans 12.0 with OpenJDK11 on Linux Mint 19.3 x64.
Trying to run some examples in chapter 1 of the
nbp4beginners book. I
just created a sample project without any module, and
tried to select
some modules from the ide cluster in the
properties-libraries window,
such as Image or Utilities. All is OK.
Then I followed the 1.2.5.5 chapter in order to activate
the XML Text
editor :
> 1.2.5.5 XML Editor

another in your

Some other related modules are selected when clicking
the "Resolve"
button, all seems to be OK, but running the project
fails, and I get an
error message (see the attached document). This message
does not help me
in finding which module is missing.
Trying again with selecting the whole ide cluster (all
ide modules are
selected), and running again the project is fine : I get
a colored
syntax when opening xml files, and there is a contextual
menu for XML
options.
So, selecting only the XML Text editor module and the
related modules by
the "Resolve" button is not enough. Could anybody help
me in finding
what modules are really needed ? I join the log file
that contains the
errors.
Note for Geertjan : this is NOT the tutorial that we
discussed yesterday
and that works perfectly :)
