Building reactive applications using asynchronous servlets

Servlets are probably one of the most (if not the most) well-known Jakarta EE technologies. Actually, servlets existed even before J2EE became a real specification.

This recipe shows you how to use servlets asynchronously.

Getting ready

    <dependency<
        <groupId<javax</groupId<
        <artifactId<javaee-api</artifactId<
        <version<8.0</version<
        <scope<provided</scope<
    </dependency<

How to do it...
