Problem running virtual service from exported war file on tomcat

Hi Everybody,

 

I'm currently trying to test virtual services (created from wsdl file) that are exported to a *.war file and deployed in tomcat. The deployment is successful, it is visible and runing when you check in "Manager App". The problem starts when I want to enter the link and view the WebUI. Everytime I get a 500 Error "com.eviware.soapui.DefaultSoapUICore cannot be cast to com.eviware.soapui.mockaswar.MockAsWarCoreInterface". 

 

Error from browser: 

java.lang.ClassCastException: com.eviware.soapui.DefaultSoapUICore cannot be cast to com.eviware.soapui.mockaswar.MockAsWarCoreInterface

I read some posts on the internet about this but they are minimum 1-2yrs old and no solution worked for me. I tried exporting the war file from two versions of ReadyApi 2.3 and 2.4, ran it on two systems windows and ubuntu and on two versions of tomcat version 8 and 9. I also tried making everything from scrach (without using a wsdl file) and also no luck.. always get that error. Can somebody help me? Anybody had this issue?

 

BR,
