Failed to process phase POST_MODULE of deployment \"myapp-ws.war\" Caused by: java.lang.-CodePudding

Presently, I have an ejb project and a web service project. The problem is that my webservice project cannot access EJBs from my library project:

{"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.\"myapp-ws.war\".POST_MODULE" => "WFLYSRV0153: Failed to process phase POST_MODULE of deployment \"myapp-ws.war\"
    Caused by: java.lang.RuntimeException: WFLYSRV0177: Error getting reflective information for class org.ws.MyAppWSImpl with ClassLoader ModuleClassLoader for Module \"deployment.myapp-ws.war\" from Service Module Loader
    Caused by: java.lang.NoClassDefFoundError: Lorg/myapp/MyAppStatelessLocal;
    Caused by: java.lang.ClassNotFoundException: org.myappp.InfossStatelessLocal from [Module \"deployment.myapp-ws.war\" from Service Module Loader]"}}

As far as I can tell the dependencies are setup properly in the pom.xml files. Here is my root pom.xml:

The ear project deploys without a problem but the webservice deployment fails. Basically, I am trying to follow this guide:

https://docs.wildfly.org/18/Getting_Started_Developing_Applications_Guide.html

https://github.com/wildfly/quickstart/blob/10.x/guide/HelloworldQuickstart.asciidoc

https://developers.redhat.com/quickstarts/eap/helloworld-ws#

Does anyone have any suggestions? TIA

UPDATE:

Here is my MyAppWSImpl.java:

package myapp.ws;

import javax.ejb.EJB;
import javax.jws.WebMethod;
import javax.jws.WebService;
import myapp.lab.MyAppStatelessLocal;

@WebService(endpointInterface = "myapp.ws.MyAppWS")
public class MyAppWSImpl implements MyAppWS {
    @EJB
    MyAppStatelessLocal masl;
            
    @WebMethod()
    public String predict(int value) {
        return masl.getPrediction(value);
    }
}

Here is my web.xml. HTH.

CodePudding user response：

Please note that I finally figured out that I needed to use this URL:

http://localhost:8080/myapp-ws/myappws?wsdl

Instead of this value:

http://localhost:8080/myapp-ws/MyAppWSImpl?wsdl
