We are using the SoapUI for generating a wsmocks.war named WAR-File and install this file into an JDK 17 based Wildfly/JBoss. So in this case we don't use the internal JDK, but we need to generate a JDK 17 ready WAR-File.
The generated WAR-File expecting a javax servlet-Class. So in JBoss 8 or Wildfly 29 there is just a jakarta lib included.
