Sample Code

public static void main (String [] args) {
     System.out.println("-------- Oracle JDBC Connection Testing ------");

        try {

            Class.forName("oracle.jdbc.driver.OracleDriver");

        } catch (ClassNotFoundException e) {

            System.out.println("Where is your Oracle JDBC Driver?");
            e.printStackTrace();
            return;

        }

        System.out.println("Oracle JDBC Driver Registered!");

        Connection connection = null;
        determineAndSetTnsHome();

        try {

            connection = DriverManager.getConnection(
                    "jdbc:oracle:thin:/@xxx");

        } catch (SQLException e) {

            System.out.println("Connection Failed! Check output console");
            e.printStackTrace();
            return;

        }

        if (connection != null) {
            System.out.println("You made it, take control your database now!");
        } else {
            System.out.println("Failed to make connection!");
        }
    }
private static void determineAndSetTnsHome() {
    String tnsAdmin = System.getenv("TNS_ADMIN");
    if (tnsAdmin == null) {
        String oracleHome = System.getenv("ORACLE_HOME");
        if (oracleHome == null) {
            return; //failed to find any useful env variables            
        }
        tnsAdmin = oracleHome + File.separatorChar + "network" + File.separatorChar + "admin";
    }

    System.setProperty("oracle.net.tns_admin", tnsAdmin);
}

Notes

Confirmed that wallet is setup. - Doing sqlplus $xxx connects fine.

- Doing mkstore -wrl -listCredential returns the entry after entering wallet password.

Thanks in advance.

Answer 1

Your wallet may be installed and configured correctly, but that does not mean the wallet is currently open. Anytime the database is restarted, the wallet needs to be opened.

Run a sample query against a known table in your schema in SQL*Plus (connecting is not enough)

If the wallet is not open you will get the following error:

ORA-28365: wallet is not open

This query should give you the status of the wallet:

select wrl_type wallet,status,wrl_parameter wallet_location from v$encryption_wallet;

In order to open a wallet, run the following command, replacing "myPassword" with the password you chose:

ALTER SYSTEM SET ENCRYPTION WALLET OPEN IDENTIFIED BY "myPassword";

Answer 2

Can you check out the blog for more details? Check if you are using TLSv1.2 and Oracle Wallets require additional jars (oraclepki.jar, osdt_core.jar, and osdt_cert.jar)
