Generate JAX-WS classes using wsgen plugin

Question

I am trying to generate the wsdl and the classes to publish the service but when I try to publish and run the generated classes these ones missmatch the current java compiler version.

I am using eclipse Eclipse version 2021-12

jdk1.8.0_321

If I check the java version in windows 10 is 8 but when I check it from the terminal in eclipse is 17.

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/motorservice/ws/jaxws/GetLibroById has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0
