I tried to create a basic virtual reality IDE based on Karaf.
I have 3 maven-projects:
- VRServer who connect to a native-component for rendering.
- VR Component Toolkit for VR-HMI-Widgets (Having a VRFrame who extends from VRComponent) as a Multi-Module-Maven-Project.
- The VR IDE project read/write files and execute lowlevel commands.
I installed all of them into Karaf:...

The main problem in the project is
true in maven-bundle-plugin. You need to have it in your pom.xml. example code
I tried using
@Named annotation on methods that create a bean, but that doesn't seem to work. Couldn't find any question here or a blog that confirms this. Reading the description at jcp.org, I don't see any relationship b/w beans and dependency injection introduced by JSR-330 either: https://jcp.org/en/jsr/detail?id=330

No, JSR-330 does not have the equivalent of Spring's
@Bean or Guice's
There are only 5 annotations in JSR-330, and they are equivalent to the following Spring1 / Guice2 annotations:
I know the default bean scope is singleton when we use
But what if we use JSR-330's
@Inject with spring's
@Component (without using
ANSWERAnswered 2020-Jan-12 at 11:30
There's no difference between @Inject or @Autowired
two annotations works the same way as Spring has decided to support some JSR-299 annotations in addition to their own
Note JSR-299 is built on top of JSR-330
JSR-299 (Java Contexts and Dependency Injection), with Gavin King as lead, uses JSR-330 as base and enhances it significantly with modularization, cross cutting aspects (decorators, interceptors), custom scopes, or type safe injection capabilities. JSR-299 is layered on top of JSR-330
All spring beans, as
@Component, are by default singletons
singleton bean is quite different from the Singleton pattern as defined in the seminal Gang of Four (GoF) patterns book. The GoF Singleton hard codes the scope of an object such that one and only one instance of a particular class will ever be created per ClassLoader. The scope of the Spring singleton is best described as per container and per bean. This means that if you define one bean for a particular class in a single Spring container, then the Spring container will create one and only one instance of the class defined by that bean definition. The singleton scope is the default scope in Spring
No vulnerabilities reported
You can use JSR-330 like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the JSR-330 component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
