Re: How do I get local terminal to work for cross platform development Windows - Debian Buster

Do you need the Terminal window on the RPi3? Don't you already have a
terminal window there that you can use? How is this blocking you?

Re: How do I get local terminal to work for cross platform development Windows - Debian Buster

 Thanks for the quick response but I think that you have answered a different 
problem.If I run Netbeans on Windows locally and try to open a Terminal Window 
I get the message 
""Local Terminal requires cygwin. Please install cygwin and restart the IDE".
This is annoying but it is not the problem that I am trying to fix (at least at 
the moment).

My problem is that, from Windows, I have opened a project not on the local host 
but on the RPi3. I have then manged to compile, build and run it on the 
RPi3.However if in Netbeans I try to open a terminal window which I assume is 
on the RPI3 I get the message "Local Terminal is not supported on this system" 
- this is not the same error message as opening a terminal on the windows 
machine.
Are you saying that installing cygwin on the Windows machine would allow me to 
open a terminal window on the Windows machine and on the RPi3?In my head, at 
least for now, these are separate issues?

I am running Apache Netbeans 12.2 on Windows 10.My target machine runs 
Raspberry Pi OS (Debian Buster).
I have managed to develop a very simple C program using Netbeans on the Windows 
machine and to get it to compile and build on the RPi3.When I run it though the

a Carriage Return (CR) and Line Feed (LF) only the LFs appear.
If, in NetBeans on the Windows machine, I try to open a terminal window I get

What is the problem, how can I get Netbeans running on the Windows machine to 
open a terminal window on the Linux machine ?

Re: [Netbeans Platform] Error when activating XML Text Editor in a new project

[Geertjan Wielenga]

Indeed, that’s not what the NetBeans Platform is for. It is an advanced
framework for handling complex task, definitely not a beginner’s tool.

Just like you shouldn’t start with power tools in other fields, i.e., don’t
start with the chainsaws if you’re getting started with basic carpentry.

But also don’t walk out of the carpenter’s meetings just because you’re
uncomfortable with the chainsaw. :-)

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

As you can see, what you’re doing doesn’t work. You can continue being

they’re meant to be used — especially if you’re putting an IDE

 Geertjan, I do not understand why the transfer to Apache is so complex and

are welcome, but not needed if the text of the tutorial gives enough details 
and is OK. Thank you for the cleaned piece of code, I could rebuild and run the 
XML tutorial.
 
 I cannot contribute to improve tutorials if I do not understand them, as my 
knowledge in Java and Netbeans is rather low. But I consider that pointing out 
errors in the doc is also a contribution. Maybe the users list is not the right 
place to do that, but I don't want to do anymore and create a new account on 
github in order to contribute, at least until I have a better knowledge to be 
efficient.
 
 Maybe you think that I am only a "consumer", but I am still at the learning 
stage with the Netbeans Platform. I am reading the nbp4beginners book, and I 
need also good tutorials. But you can't say that I am only a "consumer" : I 
know what is an open source project and a community, and I am a contributor for 
the community of Apache OpenOffice and LibreOffice users for which I spent most 
of my free time using Netbeans to develop and update a JavaDesktop tool that

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

Re: [Netbeans Platform] Error when activating XML Text Editor in a new project

[Richard]

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.

A better approach than building up an IDE from scratch, as you seem to

need. It’s the exact opposite to what you’re doing, please consider it.

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 ?

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

So, selecting only the XML Text editor module and the related

 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

 options.

 So, selecting only the XML Text editor module and the related modules

 errors.

Does this have anything to do with removal of XML binding in Java 11
timeframe?  And maybe need to add a dependency for this to the project?

Re: [Netbeans Platform] Error when activating XML Text Editor in a new project

[Geertjan Wielenga]

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.

Text Editor and you will be prompted via the red Resolve button to 
include other XML-related NetBeans

modules


Some other related modules are selected when clicking the "Resolve"

Re: NetBeans installed but can't execute

[Laszlo Kishalmi]

Well, first make sure that you have removed the netbeans package with apt:

sudo apt remove netbeans

When that's installed the Snap package does not work


Also I've noticed that your JAVA_HOME is bad. It should not point to the 
java executable, but a the directory where Java is being installed. On 
Ubuntu it is usually: /usr/lib/jvm/ java-8-openjdk-amd64 or 
/usr/lib/jvm/ java-8-openjdk-amd64


However the best thing you can do is not set the JAVA_HOME at all. So 
I'd recommend to remove the your JAVA_HOME from wherever you set that 
and reboot your machine.
