Wicket (9.8.0) application, deployed on Payara 5.201 throws exception when method of stateless beans is used

Question

Using wicket version 9.8.0, I am trying to use WicketTester for application containing EJB injection related code. I created application using 'wicket.apache.org/start/quickstart.html', and deployed it on Payara server '5.201'. I added the JavaEEComponentInjector in WebApplication. Deployment was successful, and I was able to see the page on web browser. Complete code is available at https://github.com/rjngshn/WicketTesterEJB

After this I added one stateless bean as follows

package uk.ac.ox.ndph.ckb;

import javax.ejb.Stateless;

/**
 * @date 2022-04-01
 * @author rajanis
 */
@Stateless
public class ControllerRts {
    private static int appId;
    private static String rtsPojo;
    public void init(String rtsServiceData){
        rtsPojo = rtsServiceData;
        appId = 2;
    } 

    public static int getAppId() {
        return appId;
    }
    
    public String getContactMail()  {
        return "ContactEmail";
    }

    public String getLoginMessage() {
        return "LoginMessage";
    }

}

And one singleton bean

package uk.ac.ox.ndph.ckb;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;
import javax.ejb.EJB;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import javax.ejb.Timeout;
import javax.ejb.Timer;
import javax.ejb.TimerConfig;
import javax.ejb.TimerService;
/**
 * @date 2021-03-29
 * @author rajanis
 */
@Singleton
@Startup
public class RTInitializer {
    static int MIN_TO_MICRO_SEC = 60 * 1000;
    @Resource
    private TimerService timerService;
    @EJB(name = "ControllerRts")
    private ControllerRts mControllerRts;

    // Default is 60 minutes
    private final int currentFrequency = 60;

    @PostConstruct
    void init() {
        System.out.println("RTInitializer... starting timer with default config");
        if (!isEnvironmentSet()) {
            System.out.println("RTInitializer:In Init:Environment not set");
            return;
        }
        System.out.println("RTInitializer .. Finished initializing");
        setTimer(currentFrequency);
    }

    /**
     * Specifying frequency of sending mails.
     * Method to initialize and
     *
     * @param dur
     */
    public void setTimer(int dur) {
        System.out.println("RTInitializer: Setting a programmatic timeout for download sweep frequency to " + dur  + " minutes from now.");
        Timer timer = timerService.createIntervalTimer(dur * MIN_TO_MICRO_SEC, dur * MIN_TO_MICRO_SEC, 
                new TimerConfig("Created new interval for CDAScheduler", false));
    }

    /**
     * The actual timer method which calls the EJB function to pull email
     * requests and sends emails.
     *
     * @param timer
     */
    @Timeout
    public void sweepDownloadsAndEmail(Timer timer) {
    }
    
    private boolean isEnvironmentSet() {
        String rtsServiceData = "Some string to connnect to service";
        mControllerRts.init(rtsServiceData);
        return true;
    }
}

And I referred to the stateless beans as follows in BasicPage

@EJB(name = "ControllerRts")
private ControllerRts mControllerRts;

And invoked its method in 'onInitialize'

    add(new Label("helpMessage", mControllerRts.getContactMail()));

Now the deployment as well tests failed.

Exception for deployment was as follows:

Can someone please help?

Example provided by wicket [link](https://github.com/bitstorm/Wicket-tutorial-examples/tree/master/EjbInjectionExample) gave same error. Adding Jakarta dependency version (9.1.0) worked. However adding same dependency in my project didn't work. Accessing method of stateless beans threw NullPointerExcetion. Changing bean's annotation from '@Stateless' to '@ApplicationScoped', and accessing 'public static' variable instead of method from 'WebPage' ensured successful deployment, altough it will not fulfill my requirement. Tests however fail with 'ClassNotFoundException: javax.ejb.EJB' — Rajani Sohoni, Apr 08 '22 at 09:35
Contd... Adding following dependency ensures successful execution of test. javax javaee-api 7.0 test Latest code is committed to git link mentioned in original question. Has anyone tried testing pages accessing methods of stateless beans via WicketTester in wicket version 9.8.0, payara 5.201? — Rajani Sohoni, Apr 08 '22 at 09:39

Wicket (9.8.0) application, deployed on Payara 5.201 throws exception when method of stateless beans is used
