I'm using Netbeans 12.0 with JDK 1.8.0_241 on Windows 10.
I've generated web service clients using the File > New > Web Service Client with a local WSDL file, which seems to work fine.
I would like add a keystore for signing the message header, most of the documentation I have been able to find says to right click the Web Service References > <web service name> and select Edit Web Service Attributes.
The docs also mention that the keystore information is set on the Quality Of Service tab. No Quality of Service tab is shown, only WSDL Customization and Wsimport Options. No wsit-clent.xml is generated and no <service>.svc.xml file either.
