Issue
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:

Here my my ear 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.
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

</servlet>
<servlet-mapping>

<url-pattern>/myappws</url-pattern>

</web-app>
Solution
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
