How to execute entities inside entity

http://enpoint.com/entity/business key/entity1/bk1;bk2;bk3/entity2. 

i'm trying to test above url from SoapUI 4.5.2. But soapUI is not taking this URL as single resource  and it is automatically extracting the params from the URL so that other entities are not being concidered and hence giving incorrect response as 404. could you please help me out resolving this issue.
