That's right. In order for https to work with applications written in Java, the server certificate must have been signed by an authority trusted by the Java runtime. > Is there a way to "install" the server-certificate on my client machine. > Yes, but unfortunately this is not simple because for this, you need to configure Java, not XXE. You need to do this using the command-line tool keytool (found in the Java distribution). What follows is an example of what to do on Unix (you probably need to do this as root): --- /# cd $JAVA_HOME/jre/lib/security /opt/java/jre/lib/security# ls cacerts cacerts /opt/java/jre/lib/security# /opt/java/bin/keytool -import \ -alias pixware -file /tmp/pixware.pem \ -keystore cacerts -storepass changeit /opt/java/jre/lib/security# /opt/java/bin/keytool -list \ -keystore cacerts -storepass changeit --- In the above session, you need to change "pixware" and "/tmp/pixware.pem" to your own alias and your own server certificate file. But note that the password of the Java keystore "cacerts" is really "changeit". --- PS: Note that in the second screen shot you sent me, the error message does not look like a certificate problem. Are you sure, you don't need to specify something like: "https://fs.hs-uml.de/repository/";? The fact that your Web browser can open "https://fs.hs-uml.de/"; does not mean that "https://fs.hs-uml.de/"; is WebDAV enabled. That is, HTTP GET "https://fs.hs-uml.de/"; works, but not DAV PROPFIND.
