jaspersoft studio 6.2 XML Data source ssl error

I am trying to add an "XML File" datasource in Jaspersoft Studio 6.2 to a report which is actually a call to a REST service requiring a single parameter as part of the path.

if the image doesn't display here is a description:

The URL I use is like so : http://.../service/rest/report/

Options:

GET

Parameter:

name=id

value=$P{ReportID} (the parameter is already created with a default value)

When I try to test it, this is what happens

net.sf.jasperreports.engine.JRRuntimeException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I know this should work. I can call the service in a browser using .../report/?id=xx and I get back the expected XML data. I have also tested this using the "WebService Data Source" plug-in found on the community.jaspersoft.com site - that works as well in the Studio app (but I am unable to configure it on the server).

So the question is, how do I get around this SSL exception? My app server is internal and does not use SSL (still under development).

There a two ways to tackle this:

• Ignore the certificate all together (Be aware that ignoring the error makes you vulnerable to MITM attacks)
• Add the certificate to your keystore of the corresponding JVM
