Re: How to create property/getter/setter methods for JavaFX property using NB 22

[Will Hartung]

JavaFX properties look like this:

StringPrroperty nameProperty = new SimpleStringProperty();

public String getName() {
return nameProperty.get();
}
public void setName(String name) {
nameProperty.set(name);
}

public StringProperty nameProperty() {
return nameProperty;
}

There's also a lazy version that won't create the actual property until
it's used.

StringPrroperty nameProperty;

public String getName() {
if (nameProperty == null) {
return null;
} else {
return nameProperty.get();
}
}
public void setName(String name) {
if (nameProperty == null) {
nameProperty = new SimpleStringProperty();
}
nameProperty.set(name);
}

public StringProperty nameProperty() {
if (nameProperty == null) {
nameProperty = new SimpleStringProperty();
}
return nameProperty;
}

Finally, there's this version that delays creating a property until it's
legitimately needed. This is nice if you're doing a bunch of Swing/JavaFX
crossover stuff. No need for all the properties if the bean is being used
in, say, a Swing form or table. Also nice for raw loading of beans from a
DB for a report. JavaFX properties are a bit heavy. But the bean code is
just a bit much.

String _name;
StringProperty nameProperty;

public String getName() {
if (nameProperty != null) {
return nameProperty.get();
} else {
return _name;
}
}

public void setName(String name) {
if (nameProperty != null) {
nameProperty.set(name);
} else {
_name = name;
}
}

public StringProperty nameProperty() {
if (nameProperty == null) {
nameProperty = new SimpleProperty(_name);
}
return nameProperty;
}

I just use the first, easy style in my work. I'm not working with volumes
where the properties have been an issue.

Netbeans has never had JavaFX property support that I know of.

Even Lombok does not have support for FX style properties.

Myself, I've been just cutting and pasting into ChatGPT when I need them in
bulk. "The ultimate wizard".

I love JavaFX properties, they're super powerful.

Adding support for a file extension

[Will Hartung]

I have my own little HTML templating files, but they have their own
extension.

So, even though they're 99% HTML, the IDE does not consider them HTML.
Notably, it won't let me format the files (which is all I really want,
honestly).

Is there a straightforward way to tell NB that my .tt files are "like HTML"?

Do I need to make a plugin for it? It should be a really simple one, right?

Thanks!

Can't create test for class

[Will Hartung]

I have  maven javafx project. Java 17, NB 15. It's also a modular
application with a module-info.

I try to create a test for a class, and all I get is an empty class. It has
the JUnit imports, but no test methods. Just an empty class with an empty
constructor. None of the methods.

Also, I can't seem to add any of my classes to the generated class. Auto
complete doesn't see any of the classes, and when I compile the test, it
also complains it can not find the classes.

Yet, I created a simple JavaFX project, added a test to that, and it worked
fine.

I took my pom.xml from my project, and replaced the one from the simple
project with it, and everything worked fine.

So, I don't know what else I could check to see why the testing does not
work for my project, but works for another with an identical pom file
(barring the project name).

Thanks.

Clicking on stack trace in output window

[Will Hartung]

It seems that when developing code using the Java module system (i.e. using
a module-info.java), that when you get a stack trace you get lines like
this:

at FXRdf@1.0-SNAPSHOT
/bit.fxrdf.DataSetManager.getDataset(DataSetManager.java:12)

But when you click on them, it doesn't jump into the source code, like it
does with a normal project.

Is there something that's getting in the way of this? It's been doing this
for some time now.

Will Hartung

OSGI multi-module Maven example?

[Will Hartung]

Does anyone have an OSGI multi-module Maven example?

Specifically I'm looking to a typical mutli-module maven project, where
there's a "main" project, with "libraries", which are in the submodules.

But the "libraries" are OSGI modules, and the "main" project basically uses
the modules.

I don't know what the dev lifecycle is for a Maven/OSGI project. I'd like
to just be "mvn clean install" on the parent, or just "Run" on the "main"
project.

Clearly there are several ways to deal with OSGI modules, but I'm looking
for something basic to let me move forward with OSGI participants but,
ideally, not having to shuffle a lot of things around.

Many of the OSGI basic tutorials are about loading the modules from a
framework runtime, but I'm looking to have the "main project" do that.

My fantasy is right-click -> Run, and see "hello world starting" "hello
world service activated" "Hello World!" "hello world service deactivated"
"hello world stopping".

So, if there's a "hello world" main project using a "hello world" service
that someone can point me at, that'd be great.

Will Hartung

Why is the JavaFX JavaDoc so bad?

[Will Hartung]

Why is the JavaFX JavaDoc so bad?

I'm using Maven, JavaFX 17.0.2. I've downloaded the javadocs, I've
downloaded the sources.

But during autocomplete, it seems most of the javadoc doesn't load. Not
all, there's certainly some, but if you go into autocomplete on something
(say a TextField), most of the entries are blank.

Or, something like a simple javafx.geometry.Point2D.

If you try to do a "new Point2D", and autocomplete just gives "double d,
double d1" instead of x, y.

But if you look at the javadoc:
https://openjfx.io/javadoc/18/javafx.graphics/javafx/geometry/Point2D.html#%3Cinit%3E(double,double)

The javadoc has "x, y".

This is systemic through the JavaFX libraries. Are they being built wrong?
I mean, it's JavaDoc. We've had this since 1996...

Just curious why it's so messed up with JavaFX.

Thanks,

Will Hartung

So if you open a legacy project, the behavior works? But with a new
project, it does not?

Have you tried "cloning" the working project to see if it works today? Can
you replicate your "SampleBean" example based on the older project? How do
the new project and the old projects differ?

And, honestly, it is a deal breaker. Otherwise you may as well be using a
"dumb" editor. Auto complete is part and parcel to the modern IDE
experience.

They give you a whole year to port to the new LTS!

I thought it was an interesting development. There's also apparently issues
with distributing the Oracle JDK, since lots of folks are bundling the JDK
into platform EXEs nowadays.

So, it's no panacea, but interesting.

With JDK 17, Oracle moves back to a free license

[Will Hartung]

JDK 17 is out.

And there was this interesting development.

https://blogs.oracle.com/java/post/free-java-license

Top two bullet points:

+   Oracle is making the industry leading Oracle JDK available for free,
including all quarterly security updates.  This includes commercial and
production use.

+   The new license is the "Oracle No-Fee Terms and Conditions" (NFTC)
license.  This license for the Oracle JDK permits free use for all users,
even commercial and production use.  Redistribution is permitted as long as
it is not for a fee.

So, I thought this was interesting news.

That may be, but, honestly, I haven't had any real problems with the maven
projects using whatever random JDK I have been running and having it
download the dependencies maven style.

The FX projects do have a unique POM, as the projects need a special
starting sequence. For example, you can't just right click on App.java and
click Run, you have to run the project so it can do its magic.

Maybe that's different for a JDK with FX installed.

I prefer having the project and maven do the heavy lifting than require a
magic JDK.

Re: Errors with a new JavaFX project on Netbeans 12.4

[Will Hartung]

You don't want to use a generic Maven Java project.

You should use either "FXML JavaFX Maven Archetype (Gluon)" or "Simple
JavaFX Maven Archetype (Gluon)"

It takes more than simply adding dependencies to get JavaFX to work, and
these two projects tweak the pom.xml file appropriately.

Ok, I tried that. I removed the 12.4 cache folder, went to the bin
directory and ran netbeans directly from the terminal.

it silently stops.

It looks like it's trying to start with JDK 16. Does 12.4 work with JDK 16?

I stuck a set -x in nbexec, and, among other things it showed this.

MacOS Big Sur 12.4 won't start.

[Will Hartung]

NB 12.4 won't start on MacOS Big Sur.

It used to start. It used to work fine.

But I click on the icon on my Dock, and it bounces once and quits.

I double click the app in the Finder, it tries to launch and silently fails.

NB 12.2 launches fine.

How can I start NB, I guess from the command line, to see what it might be
complaining about. I didn't see any new files or changes under
/Applications, or /Library/Application Support that would suggest something
is being logged during the start up..

So, I'm kind of at an impasse for the moment.

Simple C/C++ project not working NB 12.4 Mac Big Sur

[Will Hartung]

I have the C/C++ plugin, it says "Version 1.3".

I have XCode installed. I can type 'gcc' on the command line, and it
"works" (it's a front for clang on MacOS).

I create a simple C/C++ Application with a main.c, try to build/run

And i get

cd '/Users/will/projects/Cache64'
/usr/bin/make -f Makefile CONF=Debug clean
Cannot run program
"/private/var/folders/0s/kxxky8ls5zj8m2w99btrf9jmgn/T/dlight_will/a317ce3a/201916055/pty":
error=2, No such file or directory

If I cd to the folder, and just type "make", it seems to work.

If I type:

/usr/bin/make -f Makefile CONF=Debug clean

It works as well.

So, kind of at an impasse here.

Tips appreciated.

Thanks!

Will Hartung

Re: Netbeans 11.3 enterprise application

[Will Hartung]

The shame for this is that the reason it's broken is not, per se, "NBs"
fault.

The issue is that the maven archetypes it originally relied on are now gone
and unsupported when the hosting site up and vanished.

There's no real magic here, it's just a maven project. But the external
dependency rotted away and was never in NBs control in the first place.

And I never got a clear answer on where or how NB could host maven
archetypes published to the public repository.

Will Hartung

Re: Netbeans 11.3 enterprise application

[Will Hartung]

For the bulk of what folks do today Geertjan is right. Simply create a WAR.

WARs can host JAX-RS end points, run JSP and JSF, host SessionBeans, JPA
Entities, etc. If you're not using Message Beans, or Timers, or a select
few other things made manifest in an actual EAR application, simply create
a WAR file and move forward.

Find the appropriate version of the library your server is using, grab its
source code, and set breakpoints. With Maven, you (might) be able to
download the source attached to the library from the repository. In that
case, you can set breakpoints within that source code.

If you do download the source code, you don't have to worry about any
project structure. You can just create a new project, and drag the source
into it. You don't need to build it, just need to make the IDE aware of it.

The real game is making sure the versions match, that can't take some
digging to find out what version your server is using.

It helps if you can build the server from source, but even that only goes
so far. In your case, WIldfly doesn't build the Apache CXF stuff, it just
imports it. But at least by looking at the server source, you can ideally
ascertain the correct dependency that they're using.

No.

There was chatter of adding an MVC style action framework to the JEE
standard, but I believe that has stalled. The call for those kinds of
frameworks has diminished greatly with modern web technologies.

JSF is still going strong, however. It's really crazy powerful. The generic
web components view of it just scratches the surface.

Yes, that works.

Curiously when I go to the shortcut field, I hold down CTRL and H and it
appears as CTRL+BACKSPACE (which overrides "remove surrounding code", which
I can't find on a menu anywhere).

It does not show up as CTRL+H.

Mind, I wrote a simple Swing app and added a KeyListener to a control, and
it seems to be showing CTRL and H, not BACKSPACE. So I don't think it's a
Mac Java thing, plus it works with a raw 12.4.

So, odd all around.

Of course I could, but that's not the question.

Something Changed from a clean 12.4 and whatever my current settings are,

^H not working for Replace function on MacOS

[Will Hartung]

This is not new, it's been sort of plaguing me for some time, across NB
versions, across OSes.

Simply, Ctrl-H does not work for the Search/Replace function.

I press Ctrl-H and I just get a beep.

I have my Caps Lock key bound as my Ctrl Key, but that's not it as all of
the other Ctrl combinations work (NB shouldn't be able to detect that
anyway).

I don't know what makes ^H special in this case, or where I can look to fix
it.

It may very well be local to my configuration. I think it used to work on
my office mac, but it's not working on this one, or my previous one.

And I have no idea where to look to figure out what's going on.

If I remove the Application Support/Netbeans/12.4 folder, the IDE starts,
asks to import 12.2, and I say no. ^H works then.

I went to Preferences->Keymap->Manage Profiles->Netbeans->Reset Defaults,
and that didn't fix it either.

I tried exporting the Keymap, but nothing shows up there either.

Any suggestions?

Too many open gradle files

[Will Hartung]

So, running 12.2, "routinely", recently, my IDE has been just seizing up
saying that it can not get exclusive access to a bunch of files (like my
.java files in my project).

The only recourse was a hard kill of the IDE, which loses any pending
changes.

Somehow, I don't recall how, I managed to see a mention about "too many
files" being accessed. Simply, the process had run out of slots for open
files.

It happened again and I managed to fire off "lsof -p " to get a list
of open files.

It returned a list of almost 13,000 (12,957 to be exact) entries.

After some digging around, over 12,000 of them were referring to
directories in my ~/.gradle directory.

To be honest, I didn't even know I had a .gradle directory.

I checked it, and I found only ("only") 2500ish files/directories
underneath .gradle.

Further study found things like this:

 496
/Users/will/.gradle/caches/modules-2/files-2.1/org.openjfx/javafx-base/14
 469
/Users/will/.gradle/caches/modules-2/files-2.1/org.openjfx/javafx-graphics/14
 448
/Users/will/.gradle/caches/modules-2/files-2.1/org.openjfx/javafx-controls/14
 260
/Users/will/.gradle/caches/modules-2/files-2.1/org.glassfish.jersey.media/jersey-media-json-jackson/2.30.1
 259
/Users/will/.gradle/caches/modules-2/files-2.1/org.jboss.spec.javax.transaction/jboss-transaction-api_1.2_spec/1.1.1.Final
 259
/Users/will/.gradle/caches/modules-2/files-2.1/org.jboss.logging/jboss-logging/3.3.2.Final

This says that I had the ...javafx-base/14 directory open 496 times.

Now, I don't use gradle. I did discover I had a gradle project I downloaded
opened in the IDE.

For the time being, I have renamed .gradle to .gradle.old, to hide it from
the IDE. I've reopened my IDE, and the gradle project is still open, but I
haven't tried to build it (I don't plan too), and the .gradle directory has
not reappeared. So, I will leave it linger for the time being.

I should note that when the IDE locked up, I had not (directly) accessed
the gradle projects,nor built them. The IDE may have dug these up during a
project scan, that's just a guess.

But curious if anyone else has encountered such a thing.

Re: hashCode: same every run?

[Will Hartung]

That loophole about different values from run to run is solely for the
default implementation of hashcode, which is based on the actual internal
implementation of the instance.

Consider:

class MyClass {

int val = 1;

public MyClass() {
}
}

MyClass c1 = new MyClass();
MyClass c2 = new MyClass();

System.out.println("c1 hc = " + c1.hashCode());
System.out.println("c2 hc = " + c2.hashCode());
System.out.println("c1 == c2 " + (c1 == c2));
System.out.println("c1 eq c2 " + (c1.equals(c2)));

c1 hc = 401424608
c2 hc = 2101440631
c1 == c2 false
c1 eq c2 false

By most accounts, these two instances (c1 and c2) are "equal". They both
have the same internal state (but are not the same object, == fails as it
should). But the default JVM equals implementation does not check the
internal state of the object.

As long as this process is running, c1 will retain it's hash code, and so
will c2. But if you run it again, there is no guarantee that these values
will be the same, just consistent within the specific executable.

But, this is not how hashCode and equals are implemented in the real world.
By default the JVM does not "properly" implement hashCode and equals. I
mean, arguably, it's accurate: here are two instances that not not "equal",
thus they don't have the same hash code. By that aspect of the contract,
it's fine. It's just not very useful, and thus requires all classes having
to implement their own versions of equals and hashCode.

Since the classes inevitably dictate the behavior of equals and hashCode,
they can "guarantee" that the values returned transcend the execution state.

You can analyze the hashCode implementation for String and discern whether
the value may change from run to run (it won't, but you can at least
check). You can discern this from any class that implements equals and
hashCode. So, for 99.99% of the use cases of hashCode, changing values
from run to run is not an issue, and is under the developers control. The
docs simply say it can because the default implementations of hashCode do
that. The default implementation of hashCode isn't particularly useful for
most use cases.

Yes, timer beans are another thing.

IMHO, Timer beans are "OK", but I've had more issues with them than not
over the years, particularly in a clustered/load balanced environment. Most
timer beans are not just singletons, but cluster wide singletons. So
there's hoop jumping involved to handle that.

The idea of a cron job is sound. Today, I would just use a cron job to
tickle a simple web service trigger to start the job. This has the
advantage that in a load balanced environment, you point this to the
frontend load balancer, and any one of the backends handles the job. This
solves the problem of not having to worry about which machine controls the
timer beans, having to orchestrate which ones are doing what, prevents
having the master node problem of "we'll run timer beans on node 1", which
is fine until node 1 is down for some reason.

The dark side of cron jobs is that they will run whether the previous job
has completed or not. Not a problem for a report that runs at 2am, but can
be a problem for something that runs every 1 minute, or 5 minutes. Also,
cron only has 1m resolution.

So, that's a concern as well. All of these have issues, you just have to
pick what fits you best.

Best part about a URL triggered job is if something goes awry, you can just
kick off the job manually. Harder to do that with timer beans.

You can also look into the Quartz library, it's a java based package that
can do cron like things, if that's of interest. (Cron is still probably a
better idea, because it's so easy to configure vs restarting an app.)

Other than that, if you're not using those EJB artifacts, like MDBs, JCA,
Timers, it should go well. I've never used the new Batch facility, I don't
know where it lives.

A single WAR certainly can simplify things.

My singular issue with this is that it simply implies that they're going to
leave stuff that "doesn't work", that they/we know "doesn't work", and have
no intentions to fix it. Having broken stuff shipped with the IDE doesn't
provide value, IMHO.

If there were actual maintainers for these, it would be less of an issue. I
can't speak for anyone else, I imagine maintaining these aren't arduous,
but they do involve ramp up time on the IDE and such. They're likely not a
quick fix. For someone familiar with the NB side of it, yea, they are all
likely pretty minor. But getting to that level is likely not quick, and
those that may have that expertise are focusing on the more difficult parts
of the IDE.

We worked with NB ant builds and libraries for many years, but it was

outweighed the costs of adoption and continued use. For my personal

And to be fair, the problem is not with Ant per se. The problem is simply
that the Ant projects and wizards within the IDE are not being supported.
And that lack of support leads to bad experiences, especially with new
users. And by new users, I mean folks new to Java, new to NB, or just new
to whatever tech they want to try ("Gee, what's it like writing a web
service?").

I have nothing against Ant, I don't like the bad experiences in precisely
the place where a bad experience can be quite disrupting -- first contact
with the IDE.

As the paraphrase goes: "Patches welcome". If someone would like to chime
in, step up, and audit and update the Ant projects, then the door is wide
open.

But having them linger in limbo just isn't satisfactory to me, but I don't
think someone would want me (or anyone) to just make a pull request yanking
them out.

There are several issues, depending on your project.

If you have a "simple" Ant project, it's mostly a matter of copying your
code over, resolving the dependencies (i.e. correlating the libraries you
use to the ones in the repository), and building.

The singular "huge" amount of overhead for Maven is the large index that's
routinely downloaded from Maven Central, cataloging all of the available
libraries. It's a large download that's uncompressed on the file system (>
1GB).

Outside of that, Maven is lightweight.

Ant is faster, to be sure, but Maven is "fast enough" for most cases.

For complicated projects, anything goes. Maven is a declarative system.
"This is what I want done" vs Ants imperative system "This is what I want
to do". There is an absolute paradigm mismatch between the two, but that
does not mean it's not reconcilable.

The other side of the coin is that, technically, this isn't the place for
converting Ant to Maven. That's a "Ant" problem or "Maven" problem, not
necessarily an IDE problem.

That said, perhaps we could get a write up on someone going through the
process on some of the common NB Ant projects to show how it's done. An
automated system would likely be more complicated and less effective than a
list of steps and heuristics that someone can go through. No ideal, to be
sure.

If you'd like to contact me directly with specifics about your project,
maybe I can help you prototype a project transition.

That said, as I mentioned in the other thread, I don't think that NB should
give up legacy support of such projects, just perhaps deprecating the "new
projects".

Well, it's several things.

EARs are less popular because their necessity has been greatly reduced.
Session beans can be placed in WARs now, so for many use cases, a WAR is
completely adequate to the task.

However, it's not suitable for all use cases.

Notably, MDBs can not be deployed in WARs. But only as an EJB either
deployed standalone, or bundled within an EAR.

With the hue and cry over micro services and "down with the monolith", just
the idea of a large application bundled in a EAR is falling out of favor.

Also, there's a history of advocacy underlying this. Sun used NetBeans as a
mechanism to advocate for Java and Java EE. It behooved them to have
something like NetBeans to make Java EE development easier. So, it was
important for NetBeans to have really first class Java EE support. Bundling
the Java EE wizards and templates along with Glassfish all helped promote
that.

Of course, now, with the great Java Diaspora out of Oracle, the goals and
drivers are different.

For your project, if all you have is a web app and some session beans, then
a simple WAR file is good to go. The Ant projects seem to essentially be
deprecated now, so I would not rely on those for anything. If practical,
especially if your project is young, I would migrate it to Maven. The Maven
WAR is a pretty simple project and seems to work ok. Maven isn't going away
any time soon, Gradle, it's primary competitor, doesn't really have the
traction to overcome it yet, and it's been going for some time. If nothing
else, the pom.xml file has become a de facto portable project format if,
for nothing else, to capture dependencies.

Honestly, I think NB should have an internal conversation about removing
the "new project" support for Ant projects, while still being able to open
existing ones. It just confuses a lot of people if they're not going to be
supported.

And I still haven't heard any concrete position the project has on
internalizing Maven archetypes used for project wizards, or the process of
adopting that.

Legacy archetypes that used to work in NB 8 are now failing because they've
vanished from Maven central. So, an external dependency broke an internal
feature.

Feel free to follow up with specific questions about getting your project
to work and/or converted to Maven.

It's not that simple.

There is an EJB project wizard that takes parameters to discern which
modules to create. This is for the EAR with EJB and/or WAR module. It
creates a master project along with up to 3 sub-projects (EAR, EJB, WAR).

These are based on maven prototypes, but the person that went through and
made everything wars, just stomped on this workflow when trying to upgrade
to the more recent versions. Honestly, it was really egregious.

Also, Netbeans does not "own" the maven prototypes used for the projects.
They're hosted someplace completely different. The originals are hosted
someplace that I don't think exists any more. Codehaus I think. The WAR
ones are hosted on someone's github.

And by "hosted", I mean that the prototypes are registered with Maven
Central, but the source code to them is not part of the NB source code.
When I asked before, nobody really chimed in on whether NB can/should host
these prototypes (I think they should), or how the build servers are or can
be accomodated to post the artifacts to Maven Central (where they must be,
or at least hosted in some Maven repo that NB "knows" about in order to
generate these).

I should also say this is for the Maven based projects, I have not looked
at the Ant ones in some time. The maven ones are just a wreck.

And, yea, when this was last broached it was sort of a "nobody does this
any more", so I backed out as well.

Stack trace not highlighting and clickable

Adding jar to java modules maven project

[Will Hartung]

Working with a JDK 11 project that uses module-info, how do I add a
dependency that's not modularized? That's just a plain, legacy jar?

can't see it, etc.

So how is that done?

Tying File Type/TopComponent in to IDE

[Will Hartung]

I have a custom file type, created with the wizard.

I do not want the text editor associated with it. I just want a GUI. I've
been playing with this off and on for some time now.

My DataObject has its own DataNode with createNodeDelegate and TopComponent.

The DataNode inserts OpenCookie into the lookup.

In the end, this seems to work. The file type appears with the proper icon
in the Favorite window, I can double click and the gui opens, it marshals
my data, and I can open different ones at the same time. If I open the same
node again, it returns the original window.

However, from the file type wizard, my DataObject has several action
reference annotations

With this it has references to: Open, Cut, Copy, Delete, Rename,
SaveAsTemplate, among others, all referring to the openide actions, such as
org.openide.actions.OpenAction.

However, when realized, none of these manifest in the IDE. When I open the
file, the EDIT menu does not appear in the main menu, the right click menu
is nothing but Open, the toolbar is mostly blank.

I have a simple button that put a Savable in to the lookup from teh
TopCompont, but that seems to do nothing. In fact, there's not "save" or
action at all.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
  Savable s = new Savable() {
@Override
public void save() throws IOException {
System.out.println("Saving " +
getLookup().lookup(PersonaDataObject.class));
}
};
ic.add(s);  //InstanceContent of TopComponent done in constructor
with  associateLookup(new AbstractLookup(ic));

}

How do I tie this together to get these default IDE actions into my File
Type.

I have tried this with calling the registerEditor method, and not calling
it. The annotations are there to build up the layer.xml file, as I
understand it. I was thinking maybe I was stomping on the lookup with
DataNode when I added the OpenCookie.

private PersonaDataNode(final PersonaDataObject obj, InstanceContent
ic) {
super(obj, Children.LEAF, new AbstractLookup(ic));
ic.add(new OpenCookie() {
@Override
public void open() {
TopComponent tc = findTopComponent(obj);
if (tc == null) {
tc = new PersonaTopComponent(obj);
tc.open();
}
tc.requestActive();
}
});
}

But this code seems idiomatic to me.

I have most of the Netbeans books, but they don't explicitly address this.

There is some magic somewhere that I'm missing, I feel.

Thanks,

Will Hartung

Updating text file in MultiView

[Will Hartung]

I have a XMLMultiView from the generic New File Type wizard.

I'm creating the GUI form for the XML file.

How do I keep the XML file up to date after I make changes in the GUI?

Do I need to create a Saveable and put it in the lookup to mark it as
"dirty", or will that happen automatically when the XML file is updated?

Can I update the XML file only when the tabs are switched vs for every
change? In that case, I would have to add a Saveable since the XML may not
have changed yet.

Anyway, how does that workflow all work out?

The big move has been to Javascript top to bottom, using Single page apps
in the browser and Javascript (ala Node) on the back end.

I am not keen in that world. JS has been reinventing the wheel much like
Java did in the 90's and 2000's. "Make the world JavaScript".

I can't disagree too much with that call. Early on, when I originally chose
Java for a project it was because of JSP and Servlets. Specifically, JSPs
WERE Servlets, just in a different form. This universality was important as
they could all be treated the same. Having a Java stack from top to bottom
I felt was important to leverage the network effect of the staff. What I
did not want was someone with a XXX problem unable to talk to someone else
because they only knew YYY. This was my concern at the time with the
Microsoft stack of mixing ASP and C++ and VB (pre .Net). I wanted the team
to have the same footing.

In fact, I was quite vocal, years later, when someone decided they "just
had to" use Clojure for a component of the system. Now, I'm a Lisp guy, I
like Lisp, I can see the charms of Clojure. But if we kept that, we would
have had 20 Java folks, and 1 Clojure guy. Inevitably, the Clojure guy
left, and we had 20 Java folks and no Clojure folks. And, naturally, we
later had some issues with the Clojure code that took far too long to
resolve because we didn't have the expertise in house. Whatever potential
advantages that brought in development (which I assert were minimal, since
I rewrote the Clojure code in Java, which I was told wasn "impossible" to
"prove" that it could be done, and, no it was not as elegant as the Clojure
was, but totally serviceable), were lost when we had to fight that issue
later.

So, I can understand the desire for consistency across the team and code
sharing and reuse across the platform.

Formally, Struts in any form has nothing to with JEE. It's only a
competitor to a portion of Spring.

Struts 1 needs to die in a fire. It should remain only to be held up as an
example of things not to do, especially today. It's single claim to fame
back in the day was simply that it arrived first. Struts 1 is awful, IMHO.
Modern JSP and Servlets alone are far better, and there are much better
frameworks. Struts II is a vast improvement and related to Strut 1 in name
only. I would put them both aside, frankly.

In JEE, you have JSP 2.x + Servlets and JSF. JSP 2.x is, IMHO, one of the
finest web application templating systems out there. JSP + Tag files +
Expresion Language is really powerful. If you want a templating language
for other things, JSP is a rough fit. But if you want one for web pages,
it's really remarkable.

That said, modern JSF is really amazing. It's really powerful, but it
certainly comes with complexity. JSF is a true modular and component based
framework that scary powerful abstractions can be laid upon. Most people
don't take it there, but the underlying capability is there. If you were to
go with a more server side rendering system, JSF is very viable.

There's been calls for a JEE standard MVC framework. Struts II was
considered an MVC framework. The term "Action Framework" is another term of
art for it. That effort stalled and derailed when Oracle dumped JEE on to
the world. I don't know the current status. Spring has an action/MVC
framework as well. JAX-RS with a little work is a pretty usable action
framework.

Today, most folks seem to trend to javascript heavy, single page apps with
JSON backend services. In that case, you don't need much of anything server
side. I can not speak to those, as that's not my area of expertise. As a
rule, I find most modern webapps to be not very good. There needs to be a
balance between the heavy pages and static pages with live controls. In
that realm, I think JSF is a better fit, but I have not worked on such an
app in some time.

We've been running a cluster of GF/Payara servers for years. It was an
adhoc cluster, not using the in built GF facilities for deployment. Rather,
we just did sticky load balancing with little session sharing, and JMS
topics for crossleg communication. It was originally done for availability,
keeping the system up if one leg were to go down, so it was just two legs.
We eventually had to move to 3 for performance reasons as a single machine
could not take the traffic. GF has some nice clustering facilities, but for
us it was simply easier to manage the deploys to the legs manually than to
practice and learn the GF kit. We were live and just not inconvenienced
enough to try to pursue it.

We also run an OpenMQ cluster across all of the machines. We had good
success with OpenMQ, but we certainly beat the heck out of it and have had
different issues surrounding it.

The back end is Postgres that has a live streaming replica. The front end
is HAProxy. We are running 3 Payara instances on each leg, each supporting
a different part of the application. We also had an independent cluster of
3 Payara instances running a specific service that has since been migrated
to a completely different service. All of these were integrated via SAML
SSO. We broke the applications up in Payara mostly for monitoring and
independence. When things went awry it was much easier to find which
application was misbehaving when they were isolated like that. But we
certainly had scenarios in the past in lower load environments where
everything was on one instance of Payara. The dev server, for example, had
everything in a single instance.

AWS Aurora Postgres is an impressive piece of kit. It's quite remarkable
how a database implementation can change when you assume you have dozens of
machines, stable memory, high bandwidth networking, and geographical
isolation. If you're friendly to AWS, it's worth considering, but you can
not use a cloud database without the rest of your application co-deployed
in the same infrastructure. The lag will crush you.

Re: NetBeans IDE 12.2 - Failed to automatically set-up JavaFX Platform

[Will Hartung]

Are you using the Ant based projects?

I have been able to create JavaFX using the Maven templates just fine using
12.2 and JDK 11.

And the Ant based projects may very well be dated and not well tested or
supported.

I tried one of those and NB doesn't quite know about my JDK 11 platform, at
least as far as the wizard is concerned.

But the Maven ones point to all the new dependencies that are downloaded
automatically and so far work great. It should be straightforward to adapt
the book's examples to Maven projects.

Re: Java FX Scenebuilder w/12.2

[Will Hartung]

Yea, that was it. When I went to the JavaFX tab, it also installed a new
module.

Just odd that these settings did not get imported over from 12.0 as I would
have expected.

Thanks all!

One thing I think I noticed was that in 12.0, when I clicked on a FXML
file, there was an Open and Edit option. If I double clicked on the file in
12.0, it would open SceneBuilder. But if I clicked the Edit menu option, it
would open the XML file in NetBeans.

On 12.2, I no longer see Open and Edit. I see Open, View, and Open
Advanced...

Neither View or Open Advanced... do anything.

Oh, and this is on Mac OS Mojave.

Java FX Scenebuilder w/12.2

[Will Hartung]

I just installed 12.2 and imported my 12.0 settings.

In 12.0, if you double click on an FXML file, it would open the file in
SceneBuilder.

In 12.2, it does not. Is there a setting I'm missing?

Does NetBeans install a Maven settings.xml?

[Will Hartung]

I was debugging a repository issue with a maven project, and noticed that
the pom based repository was being mirrored by Maven Central.

I found this section in my ~/.m2/settings.xml file:
  

  maven-central
  https://repo1.maven.org/maven2/

*,!eclipselink.repository,!jvnet-nexus-promoted,!netbeans.repository

  

Looking over the settings.xml file, it appears that this is entirely a
NetBeans construct. (I have no memory of tweaking settings.xml myself).

Does NB install/update a local settings.xml? When does it do this?

Re: Loss of focus after using Wizards NB12 JDK 8 MacOS 10.14.6

[Will Hartung]

More follow up.

This does not seem to happen on the latest OpenJDK from Ubuntu. This is
likely a Java/Mac thing, I've seen other mentions about this happening in
other Java projects, but it's often associated with remote viewing
programs. But that's not the case here. I've also seen anecdotes that it's
"easy to duplicate in NetBeans".

Mind, I have no idea how this would even be approached. How to discern that
it is, indeed, a JDK thing specific to the Mac (but I've also heard
anecdotes of it happening on Windows).

It's spectacularly annoying. Honestly, it makes the IDE borderline
unusable. I'm debating hosting a Linux VM on my mac to move forward
(perhaps rootless x client). I've even explored VSCode as an alternative,
but it was honestly not as good an experience. I think I'd rather fight
shortcut keys and VirtualBox/Linux on a shared folder than VSCode.

(This isn't a knock against VSCode, it's a knock against VSCode using Java
from a long time NB user, it's just more pain than I'm willing to accept
right now if I don't have too. It's as much me as it is VSCode.)

Re: Loss of focus after using Wizards NB12 JDK 8 MacOS 10.14.6

Just an FYI, this also happens on the latest Oracle JDK 11.

Simple test.

Create a new class, or open an existing Java class
Add some member variables.
^IGetters and Setters
Cancel the dialog.
Caret/Focus is gone.

Loss of focus after using Wizards NB12 JDK 8 MacOS 10.14.6

[Will Hartung]

*Product Version:* Apache NetBeans IDE 12.0
*Java:* 1.8.0_261; Java HotSpot(TM) 64-Bit Server VM 25.261-b12

*Runtime:* Java(TM) SE Runtime Environment 1.8.0_261-b12

*System:* Mac OS X version 10.14.6 running on x86_64; UTF-8; en_US (nb)

Simply, whenever I use one of the wizards (like Override Method, or
anything from the ^I menu, both if I use ^I or right-click Insert Code),
the wizard runs and does its work, but after that I have no focus in
NetBeans.

I can drag the mouse, double click words, things like that. But I can't
type. I can open new editor windows, like other files, and can not type.
The caret vanishes. The only solution is to switch to another app, and then
switchback, and all is back to normal.

This is running the latest Oracle JDK. I've seen it in NB 8.x, I've seen it
on earlier instances of JDK 8.

I have not tried latest JDKs.

This may well be related.

Your application is throwing an exception, you need to dig deeper in to

The point is that odds are very high that whatever is making this plugin
incompatible is most likely some little bit of meta data. The code is the
code, NB Platform, in general, is more stable than not.

Even a developer new to the platform could probably build this add on,
tweak it to make it compatible, and bring it up to date quite quickly. I
mean, who knows, right? Maybe, maybe not.

Were someone on your team to do that, and submit the patch back to the
original developer, then, tada the module is now "maintained". For maybe a
couple hours work, until the next release of NB.

Considering the time savings and other value you gain from using this
plugin, don't you think it might be worth an hour or two to at least have
someone take a serious look at it?

Check it out, build it, take a look at it. If you have problems, folks here
may be able to give detailed tips on getting the plugin to work again. They
can readily help with the NB parts. The eclipse part, not so much, right?
And this is likely a NB issue, not an eclipse formatter thing.

AT WORST, you have a fork of this module now working for you, and you have
an internal website somewhere hosting the fork artifact so it's available
to your users as a module (this entails an XML file and your module, it's
no big deal). Not the most egregious burden. Ideally, the author will
incorporate your change and its now "up to date", just as it always has
been.

So, in total, the ask here isn't that great.

What do you think?

Well, that's an interesting point.

Now, I don't know, but I don't think there can be an "official" Apache

But there could be some semi-official "Friends of Netbeans" place that
would be "friendly" to things like that and would be a sane default for
Netbeans to go and fetch things from.
