Configuring SSL certificates for Link Java WEB Client

This documentation explains how to configure an SSL certificate for the Link Java WEB client.
Note: Please note that if you encounter the following error while configuring the HCH runtime server, you will need to import the Link server certificate into the JRE keystore or truststore. This problem occurs when java web clients try to access web servers that have server certificates signed by unknown authority.
com.hcl.tx.server.impl.ServiceException: An error was encountered when invoking an endpoint: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target.
To configure SSL certificates for the Link Java WEB client, follow these steps:
  1. Collect the WEB server certificate by executing the following command:
    openssl s_client -connect <Link server hostname>:<PORT>
  2. Copy the following content from the generated output after running the earlier command and save the certificate in either .cer file format:
    
------BEGIN CERTIFICATE------
…
-----END CERTIFICATE-----
  3. Import the certificate from the file (created in step 2) into JRE (Java Runtime Environment) keystore using the following command:
    sudo keytool -import -trustcacerts -keystore <Link installation folder>/java/lib/security/cacerts -storepass changeit -noprompt -alias <Alias> -file <Cert File path>
  4. Restart Link.
