I use GeoServer war 2.4.5 with Tomcat. When I try to add a WMS data source from add store, it gives:
"Connection test failed: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target" and wms Capabilities URL is "https://"
How can I fix this problem?
