Re: Class not found while running JBoss

2025-04-12 Thread Rick
The error is not related to "Class not found". It is an error regarding the
log handler configuration. There must be something wrong in your log
configuration.

Can't initialize javac processor due to (most likely) a class loader problem: java.lang.NoClassDefFoundError

2025-03-08 Thread Rick
Hi,

After the Netbeans 25 has been installed, I got an error message popped up
on my source code editor.

Can't initialize javac processor due to (most likely) a class loader
problem: java.lang.NoClassDefFoundError

Netbeans 25 + Amazon Corretto JDK23 + Win10
My source code was working on Netbeans 22 + Amazon Corretto JDK21 before.
My source code uses Lombok libs. If I remove the Lombok from the list of
dependencies, my source code will be fine.
Some posts online say this issue is caused by a missing lib tools.jar.
However, I cannot find this jar anywhere.

I agree with you regarding using vaadin for such a small project is kinda
overkill. I just found that vaadin+spring boot will be a full fledged
versatile frameworks can handle most either small scale or large scale
requirements. I use it as my scalable all-in-one solution in most cases. In
turn, it will bring up a bit in learning curves and other frontend and
backend technology like css, html, js, restful, microservices etc.

Using the C/C Tool Collection Descriptors - not seeing toolchain after install

2021-08-17 Thread Rick Curry
I'm using the tutorial at
https://netbeans.apache.org/kb/docs/cnd/toolchain.html

This tutorial mostly worked on Windows using 12.4.

Worth noting in 12.4:
 - I found I needed to clean and build the module each time to guarantee
changes came through
 - This meant I needed to add 8.2 support and the C/C++ add-on to 12.4 for
each test run, which was a little tedious but workable once I understood
this was the necessary cycle.
 - I created an NBM package as described.  This seemed to fail on signing,
so I added a self-signed certificate.  Perhaps add a link and say if
self-signed will work?  I don't think signing is mentioned.
 -  toolchaindefinition.xsd is nowhere I have been able to locate.
 - got as far as "7. If the new tool collection (GNU_tuned) is not
shown,..."

My current symptoms are that my new module works when I run/debug it, and
the NBM package adds, installs, and reasonably demands a reboot each time I
uninstall then remove it.  It just does not show up in my Tool Collections
when I "Restore Defaults" as I would expect.  This is all working fine when
I 'run' it using the debug copy of NetBeans and the shadow copies of the
tool collection descriptors.

Can someone tell me what piece of the puzzle I'm missing?

Added: I went digging and found
%appdata%\NetBeans\12.4\var\log\messages.log. I don't see any serious
problem there however:

Rick,

I just confirmed that it *is* an error in the tutorial. Apparently, 
that tutorial was written way back with NetBeans 7.4:


TemplateRegistration in NB7.4

This screenshot is from my NB 7.4 installation, and as you can see, 
the /TemplateRegistration/ class used to be in the DataSystems API 
module. However, by the time NB 8.2 was released, it was moved to the 
File Templates module. So, a lot of development must have happened to 
cause the /TemplateRegistration/ class (as well as the rest of the 
related classes) to be moved into their own module.


I'm betting you could file an issue against that tutorial and whenever 
someone has time they would fix the information...

Rick,

I'm going to go with an error in the tutorial. I only say this 
because all of the tutorials currently need to be reviewed for 
accuracy and, in my installation of NetBeans 16, when I enter 
"TemplateRegistration" into the search field of the *Add Module 
Dependency* dialog, this is what shows up:


TemplateRegistration

Likewise, when I type "NbBundle" in the same search field, I get this:

NbBundle

It could very well be that the tutorial you are working through has 
not been updated in a while and is still referencing where the 
classes /used to be/ located. Many changes have happened with the 
APIs over the decades.


This is why I had said in my last email to "type in" the name of the 
class you need. It will filter the modules list to only those modules 
that contain a class with that name.

How to get started with Java programming?

2019-07-20 Thread rick pizzi

Just updated to Ubuntu 18.04 on a Dell Latitude E6510.

I typically program in PHP with MySql, HTTP5,  Javascript and 
occasionally C. I wish to explore programming in Java.


I don't know anything about the language other than that it is 'C like' 
so I bought Mastering Netbeans and Java All-in-One for Dummies and have 
given them an overview at this time. I do want to continue programming 
with HTTP5, PHP and Javascript.


So, my question is, What do I download? Is GlassFish and Tomcat 
necessary, whatever they are; this all seems complicated enough without 
having to learn more stuff?


In Mastering Netbeans they talk about 
*http://www.oracle.com/technetwork/java/javese/downloads *and the Java 
EE bundle and the All bundle which I didn't find. Do I download several 
different things or one package to install everything I need?


My gut feeling is I should go with Java Platform Standard Edition ( Java 
SE 10 ?) and add the the Plug-ins for PHP and HTTP5 with the appropriate 
Netbeans Package.


Thanks in advance for help.
