How to use Websockets with Java JDK - java

i try to create server-client with websockets in JDK. Unfortunately i cannot import javax.websocket.* (As it is only java EE).
Is there a way to implement Websockets with JDK? I cant find a working example. Or do i have to use generic sockets?

If the dependency is missing download it and add it to your JAR:
Right-click the project folder for the project on which you are working, and click Properties.
Click Java Build Path in the left pane.
Click the Libraries tab.
Complete one of the following steps: To add an internal dependency, click Add JARs, select the JAR file that you want to add, then click OK.
or create a maven project and let it manage your dependencies.
Or just take a look in the tutorial how to create a maven project for websockets: tutorial

I’m Using NetBeans 11. But there is no Libraries category in the tree

In order to follow a tutorial, I need to edit my Libraries settings. However when I right click my project and click properties, there is no Libraries category in the tree. I have done a bunch of searching and the results tell me that it just should be there by default.And I know that I want to import the dependencies to the relevant dependency folder in the tree. How can i do it?
Please what kind of project did you create? specifically the build system. The build system describes what tool NetBeans will use to manage(compiling & creating the jar file) your project.
The library menu appears when your project is based on ANT.
If the above is not helpful, kindly reply and describe the steps used in creating the project.
Dependencies to the relevant dependency folder can ad by using pom.xml. just open the website mvnrepository.com and find the groupId,artifactId and version that jar file. then add it to pom file and compile.

Why my external jars are not included when creating an eclipse update site

I've created an eclipse plugin project with support for a DSL. The problem that i'm facing is i'm using some external libraries like apache commons, antlr,jface.text etc. It is running fine when i run from inside eclipse. But once i make an update site project, and install from it, none of the dependencies are copied or taken care of.It installs properly, but once i open a view which uses any of these libraries, it fails to work.
You have to export them.
Go under properties --> Java Build Path --> Order and Export and mark the libraries there
On Slider "Libraries" you can add them and after that you can mark them in Order and Export

Add Java Libraries to Eclipse

I am quite new to Java and Eclipse.
I am trying to call some functions from the jpf library from a program that I am writing in Eclipse.
Can anyone help me load or install these libraries into my Eclipse project? The .zip files are here. If these are already in the Eclipse program or there is some better way to get them, can someone also post that answer in addition to how to load any arbitrary java library.
Thanks for the help.
The JPF project page, to which you already linked in your question, contains a section about setting up the Eclipse IDE for JPF projects. A more general webpage on how to add external jars to your eclipse project might be helpful as well
download desired jar in to your local machine - add those jar to your project using below
right click on your project - configure build path - libraries - add
external jars - browse downloaded jars - add
Download and extract jpf-bin-1.5.1.zip. In here, you will find one or more JAR files. Add them into your Eclipse project, under something like a "lib" folder. Right-click on the JAR files from there, then choose "Build Path" / "Add to Build Path".
Or better yet, investigate the use of Apache Maven, and let it handle all of the dependency resolution for you. (Per http://jpf.sourceforge.net/roadmap.html, this project is at least Maven-enabled.) At least the 1.5 version is also available from the central Maven repository at http://repo1.maven.org/maven2/net/sf/jpf/jpf/. I don't see 1.5.1, but the jpf-bin-1.5.1.zip contains a "MAVEN.txt" that explains how to install it into a local Maven repository for use.

Netbeans - Add library that is currently being edited

I'm working with multiple related projects in Netbeans. Is is possible to add a library or reference to that library (made from building one of the projects) to the other projects, while I'm still editing that library? I can 'clean & build' that library everytime I edit it and then import it again to the other projects, but that would be a really tedious task. Is there a way I can do it conveniently in Netbeans? Thanks!
In the project properties -> libraries you can specify Jar/Folder, libraries or other projects. All changes in the pointing project will be available in your current project as you change it.
You still need to build it, but you don't need to import as Jar again.
When you right click on the library group in your project you can add another project as a library.
