Jasper Reports and Webservices

Hi guys! I'm able to access a webservice through my web application. But now has come to a point where I got totally clueless because I'm asked to create a reporting feature for it(the app). Reports (JasperReports) can be connected to a RDBMS and with iReport it's easy to create designs. But how am I suppose to get a record/field from a webservice and integrate that to my report?

If the moderators think that this is not webservice related please inform me as to where this topic will be moved. Thanks!

I'm fairly certain that JasperReports contains nothing that can interface with a WS, so you will have to retrieve all relevant data from the WS response, and convert it into a format JasperReports can handle. Presumably it can handle in-memory data structures of some kind?
