How do I generate classes from https WSDL link in maven using jaxb plugin

Answer 1

You need to have SSL certificate of the third party added in your truststore to access https URLs. Please check the third party URL is correct, as the domain shown in your log is shownas "localhost". It should be some valid domain.

Answer 2

The recommendation to fix your HTTPS is sound. You seem to have two problems here:
Your error points to localhost and somehow you're talking about configuring Tomcat and at the same time about "web service from a third party". localhost does not look like a third party to me.
Java does not trust the certificate provided by your HTTPS server. Either your server is using some rogue self-signed certificate OR you may have an outdated JVM which, for instance does not have some new intermediate certs (like Letsencrypt). You have to fix this in your JDK either by an update or by importing the missing certificates into your store.
However, I generally don't recommend compiling schemas/WSDLs from online resources. You normally want clean reproducible builds not depending on the well being of some server out there. Make local copies of files your want to compile and use catalogs to virtually point external URLs to your local copies. This will make your build independent of external resources.
