This is a feature of JBuilder Professional and Enterprise.
To display the Extended Properties dialog,
Use the Extended Properties dialog box to define additional connection properties that your driver may be able to use. These properties are stored in an instance of a java.util.Properties object and are not required or supported by all drivers. Refer to your driver documentation to see if extended properties are relevant. A properties table displays the extended properties that either you have defined or the driver has specified. There are three columns in the table:
Each row in the table represents a distinct property.
Creates an empty row in the table so that you can define a new connection property.
Deletes the current property by deleting the entire row of information on that property.
Accesses driver information and displays the properties in the properties table.
