When you get the above error then you possibly can add the next maven dependency (org.glassfish.jersey.containers jersey-container-jdk-http ) to unravel the issue:com.solar.internet.httpserver.HttpHandler”):

    <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-jdk-http</artifactId>
        <model>2.18</model>
    </dependency>

You would change the model based on your surroundings. Bear in mind the exception’s error message says “No container supplier helps the kind interface”. This dependency supplies the container wanted to run Jersey. 

Watch out for the distinction between Jersey and Jersey2

It’s totally simple to confuse with two totally different variations of Jersey, within the first model the lessons belong to com.solar.jersey and within the second the framework lessons go to org.glassfish.jersey. Basically solely the bundle is totally different however with the assorted dependent JAR, it’s extremely simple that JARs from Jersey 1.x combined with JARs from Jersey2.x and elevating dreaded NoClassDefFoundError and its shut cousin ClassNotFoundException.

The bundle title modified as a result of the Jersey workforce is now a part of Glassfish. The model under 2 was utilizing com.solar.jersey bundle however now for the reason that firm is totally different they’re utilizing org.glassfish.jersey. 

That is all concerning the Jersey Whats up world instance.  Jersey framework is greater than the JAX-RS Reference Implementation. Jersey supplies its personal API that extends the JAX-RS toolkit with further options and utilities to additional simplify RESTful service and consumer improvement. Jersey additionally exposes quite a few extension SPIs in order that builders could prolong Jersey to finest go well with their wants.
