newer wsgen cannot find existing WebService annotation - wsgen

Question

We have a working web service using Java 8 that we are trying to upgrade to Java 11.
jaxws-ri\bin\wsgen.bat (version "JAX-WS RI 4.0.0-M4 git-revision#ac6e723") displays the following exception:
Exception in thread "main" com.sun.xml.ws.model.RuntimeModelerException: A WebService annotation is not present on class: com.xxxxxx.security.services.webservice.SecurityServiceImpl

Result: 1
However, our SecurityServiceImpl.java class DOES contain the #Webservice annotation, as shown below
import javax.jws.WebService;
#WebService(name="Foundation Security", serviceName="FoundationSecurityWS", portName="FoundationSecurityWSPort")
public class SecurityServiceImpl {
Our ant build script uses the following wsgen.bat arguments:
<arg line="-cp ${wsgen.classpath.string}"/>
<arg line="-d ${build.webservice}/server"/>
<arg line="-s ${build.webservice}/serversource"/>
<arg line="-r ${build.webservice}/resource"/>
<arg line="-wsdl"/>
<arg line="-keep"/>
<arg line="com.xxxxxx.security.services.webservice.SecurityServiceImpl"/>
Thank you in advance for any suggestions

Answer 1

after adding debug logging to JAX-WS com.sun.xml.ws.model.*, the issue seemed to be that "import javax.jws.WebService;" needed to be updated to "import jakarta.jws.WebService;"
