https://www.winehq.org/announce/2.0

states that Wine 2.0 supports basic SOAP calls. However, these always throw an exception on Mac OSX (Big Sur, Catalina and earlier). Firewall is off.
1.Does the latest POM install 2.0?
2. Is there any workaround?

Wine 2.0 is outdated, the oldest Wine I can recommend is v3.0.3

So you are sayibng that in Wine 3, the SOAP support has been stripped out?

How to get POM to support SOAP?
