WSO2 DATA SERVICES Nested Querys. How can i - wso2

Question

we have three querys, one select and two insert queries.
We have to execute the select query and it returns a row with four fields.
Then we have to use these four fields to excute the inserts querys.
Select query works fine, but when WSO2 ESB try to execute the next nested query fails, and show the next error
Unable to sendViaPost to url[http://6f478fba7fca:8280/services/...........SOAP12Endpoint] {org.apache.axis2.transport.http.HTTPSender
This is the xml about our data service.
