In OpenStudio 6.2 I've created a working report with a Web Service Data Source, a connection is established and I receive all the required data. When I publish this report to the server and run the report I receive an error. In the jasperserver.log I see the following which indicates a connection is not established: javax.net.ssl.SSLException: hostname in certificate didn't match: <chasse.yesplan.nl> != <*.yesplan.be> OR <*.yesplan.be> OR <yesplan.be> The valid third party certicate includes the domains: yesplan.nl and *.yesplan.nl. Is this a bug in the Web Service Data Source plugin, it all works in Jaspersoft Open Studio 6.2 but not on the Jasperserver? I've include the SSL certicate to the Java keystore to no avail... Remco
