Andriy Redko commented on CXF-9102:
-----------------------------------
[~dsylaiev] your binding files does not seem right, your are generating JAX-WS
services, not JAXB classes:
{noformat}
<?xml version="1.0" encoding="UTF-8"?>
<jaxws:bindings
xmlns:jaxws="https://jakarta.ee/xml/ns/jaxws";
wsdlLocation="HelloWorld.wsdl"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/";>
<jaxws:bindings node="wsdl:definitions/wsdl:portType[@name='HelloWorld']">
<jaxws:class name="CustomHelloWorld"/>
</jaxws:bindings>
</jaxws:bindings>
{noformat}
> cxf-codegen-plugin fails to generate code from wsdl and binding file after
> update to 4.x: XPath evaluation results in empty target node
