If you’re still using Wildfly 9 Realm for database authentication, it’s time to upgrade to Wildfly 28 JDBC-Realm. The newer version offers improved security, better performance, and enhanced features. In this article, we’ll take you through the process of migrating from Wildfly 9 Realm to Wildfly 28 JDBC-Realm, ensuring a seamless transition to a more robust and reliable database authentication system.
What’s Changing?
Before we dive into the migration process, let’s understand the key differences between Wildfly 9 Realm and Wildfly 28 JDBC-Realm:
- Realm vs. JDBC-Realm: Wildfly 9 uses the Realm security domain, whereas Wildfly 28 uses JDBC-Realm. This change brings improved security and flexibility to your database authentication.
- Database Configuration: In Wildfly 9, database configuration is scattered across multiple files. With Wildfly 28, you can configure your database connections using a single file, making it easier to manage and maintain.
- Security Enhancements: Wildfly 28 introduces improved security features, such as password hashing and salting, to protect your database credentials.
Step 1: Prepare Your Environment
Before migrating to Wildfly 28 JDBC-Realm, ensure you have the following components installed and configured:
- Java 8 or Higher: Wildfly 28 requires Java 8 or later to function correctly.
- Wildfly 28 Server: Install the latest version of Wildfly 28 on your server.
- Database Server: Ensure your database server is running and configured to accept connections.
Step 2: Configure JDBC-Realm
Create a new file named `jdbc-realm.xml` in the Wildfly 28 server’s configuration directory (`standalone/configuration` for standalone mode or `domain/configuration` for domain mode). Add the following content to the file:
<jdbc-realm name="jdbc-realm-example"> <authentication-jQUERY> <login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required"> <module-option name="dsJndiName" value="java:jboss/datasources/ExampleDS"/> <module-option name="principalsQuery" value="SELECT password FROM users WHERE username=?"/> <module-option name="rolesQuery" value="SELECT role, 'Roles' FROM user_roles where username=?"/> </login-module> </authentication-jQUERY> </jdbc-realm>
Modify the `dsJndiName`, `principalsQuery`, and `rolesQuery` values to match your database configuration.
Step 3: Configure Database Connection
Create a new file named `datasources.xml` in the Wildfly 28 server’s configuration directory. Add the following content to the file:
<datasources> <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS"> <connection-url>jdbc:postgresql://localhost:5432/exampledb</connection-url> <driver>org.postgresql.Driver</driver> <security> <user-name>example_user</user-name> <password>example_password</password> </security> </datasource> </datasources>
Replace the connection URL, driver, username, and password values with your database credentials.
Step 4: Configure Security Domain
Edit the `jboss-web.xml` file in the Wildfly 28 server’s configuration directory to configure the security domain:
<jboss-web> <security-domain>jdbc-realm-example</security-domain> </jboss-web>
Update the `security-domain` value to match the name of your JDBC-Realm configuration (e.g., `jdbc-realm-example`).
Step 5: Test Your Configuration
Restart the Wildfly 28 server and test your database authentication using a tool like curl or a web browser:
curl -X GET \ http://localhost:8080/your_app \ -H 'Authorization: Basic dXNlcjpwYXNzd29yZA==' \ -v
Replace `http://localhost:8080/your_app` with the URL of your application. If everything is configured correctly, you should receive a successful response.
Troubleshooting Common Issues
If you encounter issues during the migration process, refer to the following troubleshooting tips:
- Check database connectivity: Ensure your database server is running and accepting connections. Verify the database credentials and connection URL.
- Verify JDBC-Realm configuration: Double-check the `jdbc-realm.xml` file for typos and incorrect values. Ensure the `dsJndiName`, `principalsQuery`, and `rolesQuery` values match your database configuration.
- Review security domain configuration: Verify the `jboss-web.xml` file is correctly configured, and the `security-domain` value matches the name of your JDBC-Realm configuration.
Conclusion
Migrating from Wildfly 9 Realm to Wildfly 28 JDBC-Realm requires careful planning and execution. By following this step-by-step guide, you’ll ensure a seamless transition to a more robust and reliable database authentication system. Remember to test your configuration thoroughly to avoid any issues.
