# Working with Derby SQLExceptions in an application

JDBC generates exceptions of the type java.sql.SQLException. If your application runs on JDK 1.6 or higher, the exceptions will be the refined subtypes of java.sql.SQLException introduced by JDBC4. To see the exceptions generated by Derby, retrieve and process the `SQLExceptions` in a catch block.
