Dynamic URL for WebServiceQuery

[skwong]

We want to use web service as a datasource in our Jasper Reports version 6.2. In Jaspersoft Studio version 6.2 (community) we have a Base URL defined as: https://mywebservice/location/

Content Type: GET Parameters

Name: param1, Value: $P{param1}

Our understanding is that the query generated by Jasper Reports will be: https://mywebservice/location/?param1=$P{param1}

Unfortunately the web service Base URL does not accept ?param1. Instead the URL should be: https://mywebservice/location/$P{param1}

What can be do in this case?
