Java 11 and javax.rmi.PortableRemoteObject

Question

I'm using Payara 5.29.0 enterprise server which support Jakarta EE 8.

I'm trying to port the code for Java 11.

When I compile there comes error:

    cannot find symbol
    [ERROR]   symbol:   variable PortableRemoteObject

The code contains javax.rmi.PortableRemoteObject.narrow which was used before EJB3.

Is javax.rmi.PortableRemoteObject in some library so I could add it to the maven pom.xml?

I tried dependency

    <dependency>
        <groupId>jakarta.ejb</groupId>
        <artifactId>jakarta.ejb-api</artifactId>
        <version>3.2.6</version>
    </dependency>

but I got still same error.

I could port the code to the EJB3, but I wonder is it possible to handle this only adding the maven dependency?

Answer 1

javax.rmi.PortableRemoteObject was part of the JDK itself up until JDK10. It was removed in JDK11. Everything rmi was removed in 11 if I understand https://openjdk.org/jeps/320 correctly.
