6.1. Configuring JDBC drivers Before you can connect to a DBMS you have to configure the JDBC driver to be used. The driver configuration is available in the connection dialog or through File → Manage Drivers The JDBC driver is a file with the extension.jar (some drivers need more than one file). See the end of this section for a list of download locations. Once you have downloaded the driver you can store the driver's.jar file anywhere you like. To register a driver with SQL Workbench/J you need to specify the following details. the driver's class name. the library ('JAR file') where to find the driver (class) After you have selected the.jar file(s) for a driver (by clicking on the button), SQL Workbench/J will scan the jar file looking for a JDBC driver.

If only a single driver is found, the class name is automatically put into the entry field for the class name. If more than one JDBC driver implementation is found, you will be prompted to select one.

In that case, please refer to the manual of your driver or database to choose the correct one. SQL Workbench/J is not using the system's CLASSPATH definition (i.e. The environment variable named CLASSPATH) to load the driver classes.

Changing the CLASSPATH environment variable to include your driver's library will have no effect. If you enter the class name of the driver manually, remember that it's case-sensitive: org.postgresql.driver is something different than org.postgresql.Driver Files that are not found are displayed in red and italics. The name of the library has to contain the full path to the driver's jar file, so that SQL Workbench/J can find it. Some drivers are distributed in several jar files.

In that case, select all necessary files in the file open dialog, or add them one after the other. If an entry is selected in the list of defined jar files when adding a new jar file, the selected entry will be overwritten. For drivers that require a license file, you have to include the license jar to the list of files for that driver. If the driver requires files that are not contained in the jar library, you have to include the directory containing those files as part of the library definition (e.g: 'c: etc TheDriver jdbcDriver.jar;c: etc TheDriver'). You can assign a sample URL to each driver, which will be put into the URL property of the profile, when the driver class is selected.

SQL Workbench/J comes with some sample URLs pre-configured. Some of these sample URLs use brackets to indicate a parameters that need to be replaced with the actual value for your connection: (servername) In this case the entire sequence including the brackets need to be replaced with the actual value.
