Hello Jeremy, It seems the data catalog is down, although the database itself (hpsdb.jlab.org) is functioning fine, i.e. I can do direct queries, and adding files with the Java interface works. The web interface at https://hpsweb.jlab.org/datacat/display/browser <https://hpsweb.jlab.org/datacat/display/browser> does not work right now. The error I get is shown below. Best, Maurik HTTP Status 500 - 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 type Exception report message 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 description The server encountered an internal error that prevented it from fulfilling this request. exception javax.ws.rs.ProcessingException: 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 org.glassfish.jersey.client.internal.HttpUrlConnector.apply(HttpUrlConnector.java:287) org.glassfish.jersey.client.ClientRuntime.invoke(ClientRuntime.java:255) org.glassfish.jersey.client.JerseyInvocation$1.call(JerseyInvocation.java:684) org.glassfish.jersey.client.JerseyInvocation$1.call(JerseyInvocation.java:681) org.glassfish.jersey.internal.Errors.process(Errors.java:315) org.glassfish.jersey.internal.Errors.process(Errors.java:297) org.glassfish.jersey.internal.Errors.process(Errors.java:228) org.glassfish.jersey.process.internal.RequestScope.runInScope(RequestScope.java:444) org.glassfish.jersey.client.JerseyInvocation.invoke(JerseyInvocation.java:681) org.glassfish.jersey.client.JerseyInvocation$Builder.method(JerseyInvocation.java:411) org.glassfish.jersey.client.JerseyInvocation$Builder.get(JerseyInvocation.java:311) org.srs.datacat.client.resources.Path.getContainers(Path.java:30) org.srs.datacat.client.Client.getContainers(Client.java:178) org.srs.webapps.datacat.controllers.ControllerUtils.getContainers(ControllerUtils.java:204) org.srs.webapps.datacat.controllers.ControllerUtils.collectAttributes(ControllerUtils.java:66) org.srs.webapps.datacat.controllers.BrowserController.doGet(BrowserController.java:24) javax.servlet.http.HttpServlet.service(HttpServlet.java:620) javax.servlet.http.HttpServlet.service(HttpServlet.java:727) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
