RazorSQL JDBC Bridge Interface Class There are two options when using the RazorSQL JDBC Bridge to access databases, Interface and Driver. If using the Interface method, connections to the database are obtained by calling a method on a Java class that returns a database connection. The Service Interface Class is the fully qualified name of the Java class that contains a method to call to return a database connection, for example, com.acme.ConnectionFactory. For more information, see the RazorSQL JDBC Bridge User's Guide in the help documentation.
