Documentum Rest Service - Trusting SSL certificate from Java Client - rest

Question

My Need is to accept the SSL certificate enabled on REST Webservice URL ( https:/:/dctm-rest) from standalone Java application(which will be bundled as JAR).
To my knowledge best way is to create KeyStore/TrustStore using Keytool, download the certificate from browser/openssl and add it to TrustStore.With this we are creating a dependency and someone has to keep on updating the certificate for every renewal.
Can someone guide me to get this implemented by removing the manual dependency?

Answer 1

You have to include the server certificate at https://dctm-rest into the whitelist of your JRE (the truststore)
Options
1) Include the server certificate in JRE trustore (jre/lib/security/cacerts) (Not recommended)
To download the server certificate, open site with browser, right-click on green lock, select 'view certificate' and download
The simplest way to explore cacerts and import trusted certificate is to use a GUI tool like portecle (http://portecle.sourceforge.net/). You can also use keytool
keytool -import -trustcacerts -keystore /opt/java/jre/lib/security/cacerts -alias mycert -noprompt -storepass changeit -file /tmp/examplecert.crt
See How to properly import a selfsigned certificate into Java keystore that is available to all Java applications by default?
2) Use your own truststore and include the server certificate (recommended)
System.setProperty ("javax.net.ssl.trustStore", path_to_your_trustore_jks_file);
System.setProperty ("javax.net.ssl.trustStorePassword", "password");
You can also create an SSLSocketFactory and add to your connection before connecting or apply to all connections using the static method
HttpsURLConnection.setDefaultSSLSocketFactory(sslFactory);
This is an example to create the socket factory
//Load JKS keystore that includes the server certificate or the root
KeyStore keyStore = ...
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(keyStore);
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(null, tmf.getTrustManagers(), null);
sslFactory = ctx.getSocketFactory();
3) Do not use truststore at all (Not recommended at all)
