JDBC Data Sources

JDBC data sources are direct connections to your database that are managed by JasperReports Server. To create one, you must provide the URL and credentials to access your database, along with any database-specific configuration parameters.

JasperReports Server includes JDBC drivers for the most used databases. If your data base is not included, or if you wish to use different JDBC drivers, the system administrator must upload the appropriate JDBC driver before creating a data source. For more information on JDBC drivers, see Managing JDBC Drivers.

To create a JDBC data source:

1. Log on as an administrator.
2. Click View > Repository, expand the folder tree, and right-click a folder to select Add Resource > Data Source from the context menu. Alternatively, you can select Create > Data Source from the main menu on any page and specify a folder location later. If you installed the sample data, the suggested folder is Data Sources.

The New Data Source page appears.

3. In the Type field, select JDBC Data Source.

The page refreshes to show the fields necessary for a JDBC data source.

4. Enter a name and optional description for the data source. The resource ID is filled in automatically based on the name.

Setting the JDBC Data Source Type

5. Select the JDBC driver for your database. If your driver is listed as NOT INSTALLED, a system administrator must first upload the driver as described in Managing JDBC Drivers.

Choosing the JDBC Driver

6. Enter the hostname, port, and database name for your database. The default hostname is the localhost, and the default port is the typical port for the specified database vendor. The three fields are combined automatically to create the JDBC URL that the server will use to access the database.

For more information about JDBC URLs, including optional parameters, see the troubleshooting section JDBC Database URLs.

7. Fill in the database user name and password. These are the credentials that the server will use to access the database.

Testing the JDBC Connection

Set the Time Zone field when the date-time values stored in your database do not indicate a time zone. When date-time values are stored in a format other than local time zone offset relative to Greenwich Mean time (GMT), you must specify a time zone so that the server can properly convert date-time values read from the target database. Set the Time Zone field to the correct time zone for the data in the data base. The list of time zones is configurable, as described in Specifying Additional Time Zones.

When in doubt, leave the Time Zone field blank.

8. If you have not already specified the repository folder, click Browse... to choose one in the Save Location field.
9. Click Test Connection to validate the data source. If the validation fails, ensure that the values you entered are correct and that the database is running. To diagnose JDBC connection issues, you can turn on logging as described in the troubleshooting section Logging JDBC Operations.
10. When the test is successful, click Save. The data source appears in the repository.
