Troubleshooting "Unable to Find Valid Certification Path to Requested Target" Error

When encountering the "unable to find valid certification path to requested target" error while accessing a server with a self-signed certificate, meticulous steps should be taken to resolve the issue.

Importing the Certificate and Validating Its Addition

As mentioned in the description, it's crucial to import the root certificate into the appropriate keystore. However, it's important to ensure that the Glassfish server is referencing the updated keystore. To do so, consider using the -Djavax.net.ssl.trustStore system property as follows:

java -Djavax.net.ssl.trustStore=trustStore ...

where trustStore is the path to the keystore containing the imported certificate.

Debugging with Java System Properties

Java offers extensive debugging options through system properties. To gain insights into the SSL-related operations, set the javax.net.debug property to a specific level (e.g., "keymanager" or "trustmanager") or "all" to capture all debugging information.

Additionally, keystore and truststore properties can be adjusted to explicitly specify the locations of the keystore and truststore files. For instance:

java -Djavax.net.ssl.keyStore=keyStore ...
java -Djavax.net.ssl.trustStore=trustStore ...

Understanding Keystore and Truststore

It's essential to recognize the distinction between the keystore and truststore. The keystore manages the server's private key and certificate, while the truststore contains trusted certificates used for server verification. Each certificate may have a chain of trust extending to a root certificate, and it's vital to ensure that both the server's certificate and any trusted root certificates are present in their respective stores.

By utilizing the debugging options and ensuring proper keystore and truststore configuration, it's possible to resolve the "unable to find valid certification path to requested target" error and establish a secure connection to the server.
