When you create a new data source in JasperReports Server, the new custom data source type appears in the list of available data source types. If the new type is selected, JasperReports Server displays a form containing the list of properties you configured.

When the form is submitted, the parameter values are validated with your CustomDataSourceValidator implementation and appropriate validation messages are displayed. Once the data source is validated, save it to the repository. The data source can now be used in a report or analysis connection.

When defining <queryString> in JRXML, use a language setting that your custom data source supports.

When you add a report to the repository, you can define a local data source or you can select one of the data sources in the repository. In either case, you can use a data source based on your custom data source implementation. In the case of a data source in the repository, you must create it before adding the report. If, during the creation of your data source, the custom data source is not listed as an available data source type, the custom data source is not properly installed.
