In mostĬases, the issue can be resolved by ensuring the name is specified duringĬertificate creation. Indicates that a client connection was made to but theĬertificate returned did not contain the name. In such cases, you trust that it is the correct URL, In such cases above, code can be used which will not mandate to store the certificate to connect to particular URL.įor the point no 2 we have to follow below steps :ġ) write below method which sets HostnameVerifier for HttpsURLConnection which returns true for all cases meaning we are trusting the .CertificateException: No name matching found Default trustore java uses can be found in \Java\jdk1.6.0_29\jre\lib\security\cacerts, then if we retry to connect to the URL connection would be accepted.Ģ) In normal business cases, we might be connecting to internal URLS in organizations and we know that they are correct. If server at the other site is running on https protocol and is mandating that we should communicate via information provided in certificate thenġ) ask for the certificate(download the certificate), import this certificate in trustore. Whenever we are trying to connect to URL, After you complete these relatively simple steps, you'll be communicating securely and with the assurance that you're talking to the right server and only the right server (as long as they don't lose their private key). The default password as shipped with Java is changeit. It will most likely ask you for a password.
To import the new cert, run keytool as a user who has permission to write to cacerts: keytool -import -file -alias -keystore At $JAVA_HOME/jre/lib/security/ for JREs or $JAVA_HOME/lib/security for JDKs, there's a file named cacerts, which comes with Java and contains the public certificates of the well-known Certifying Authorities. Now that you have the certificate saved in a file, you need to add it to your JVM's trust store.
(Google should be able to tell you exactly what to do for your specific browser.) That can be done in a variety of ways, such as contacting the server admin and asking for it, using OpenSSL to download it, or, since this appears to be an HTTP server, connecting to it with any browser, viewing the page's security info, and saving a copy of the certificate. First, you need to obtain the public certificate from the server you're trying to connect to.
