Java Database Connectivity (JDBC) is a widely used API for establishing and managing connections to databases. Here are some common issues related to JDBC:

  1. Missing Dependencies: Ensure that your project includes the JDBC driver for the database you’re connecting to.

  2. Invalid Connection URL: Provide a correct connection string, including the database URL, username, and password.

  3. Authentication/Authorization Failure: If the user credentials are incorrect or if there are permissions issues, the connection attempt will fail.

  4. Transaction Management Issues: When working with transactions, make sure to commit or rollback them properly to avoid data inconsistencies.

  5. Database Versioning: Keep your JDBC driver and database version in sync, as mismatched versions can cause connectivity problems.

Remember that troubleshooting JDBC issues requires careful examination of code, connections, and database schema.
