If necessary, you can download the JayBird JDBC Driver from this location. Make sure that the driver version is appropriate for your Java and Firebird versions.
The JayBird JDBC Driver is implemented in a file with a name similar to jaybird-full-2.2.8.jar (the specific file name may vary according to the version being used). You may need to copy the file to the /jar directory of your JSM instance and restart the Java Service Manager before using the driver with Transformation Maps in LANSA Composer.
Refer to relevant Firebird resources for more information on the JDBC drivers available for Firebird and the keywords and values that can be specified in the JDBC connection string. Following are some useful references.
