Deployment of Web service process failed in Activity-Explorer 5.13

[perpetuum_mobil]

Hello!
I have a problem with deployment of process containing a web service task
(in explorer: 'Manage'->'Deployments'->'Upload new')
I've got this error:

So, I got mentioned error trying to deploy this process.
Then I wanted to deploy very simple bpmn including only WSDL import:

But I've got the same error.
This old topic contains the similar problem's discussion, but I found no answer there.

Thank you.

Not sure about this, but if it's the same "http://schemas.xmlsoap.org/wsdl/" issue, maybe it's worth looking into how to make the xml-parser aware of the XSD for this URL…

Thank you for reply!
I've solved the problem.. It was, however, in cxf dependencies. There were I've uploaded 5.12 version of activity and made the same actions. So, i found info about needed dependencies in tomcat log.
By the way, 5.13's log contained only mensioned error…
