Both the data set element and the ODA driver can provide column definition and hints. An extended data source that represents a connection that implements the Open Data Access ODA interfaces to interact with an external data provider. Required if multiple result sets are available, and a result set must be accessed by name. At Factory time, these static extension-defined properties are passed to the ODA run-time driver as connection properties to open a data source. Depending on the data source you retrieve, you can override the close method in the IResultSet , as well. BIRT’s internal data engine serves as the observed object, and the developer is responsible for creating the observer.

Also, for some data sets, the data set definition can omit parameter definitions for optional parameters not used within the report. The factories must generate observers for data source connections, data set queries, parameters, and result sets see Figure 1.

The composite that is created calls the DataSourceWizardPage. The method returns true if there are remaining rows and false if there are no other rows to return. The inherited resultSet definition, if specified, is for this result set.
A custom driver class must implement one method named connect. Labels Charts 10 Fonts 1 format 1 scripts Creating the pages for the data source and data set editors is a simple matter of registering property pages in the manifest editor, and then creating Standard Widget Toolkit SWT composites.
I am Rupesh I create custom parameter page i get fioolwing error java. In addition the driver has been improved by adding a driver class path property to locate your custom connection class. You must write each of the get column methods and get data type methods.
ODA Data Set Element (Eclipse BIRT ROM Documentation)
In the example code, the RptDocPropertyPage. The Eclipse Business Intelligence and Reporting Tools project is an open-source project focused on the development and delivery of framework tools for reporting and business intelligence within the Eclipse platform. I am using Birt 2.
This article walked you through the process of creating two plug-in projects—one for design time and one for runtime. It is responsible for opening the data connection to the data source. Depending on the data source you retrieve, you bitt override the close method in the IResultSetas well.
You can then apply sorts during the retrieval process. The definition for both can be seen in the newDataSourceWizard and the designer data source connection properties in the manifest editor.
BIRT World: BIRT Web Service ODA
By osa an ODA that can retrieve data from a report document file, you can write reports against existing reports, opening a whole new set of possibilities for the open source BIRT, such as run-once data sets that you can reuse for multiple reports. For other data sets, the driver itself can provide the set of parameter definitions from oca information available in a data set query.
At Factory time, these static extension-defined properties are passed in name-value pairs to the ODA driver as a query’s run-time properties.
This is an optional list of data set parameter definitions, used only when the underlying data provider cannot provide this information. On the next wizard page leave everything as it is, just press the Test Connection button to verify the connection is successful.
This property identifies which named result set to access. Posted by Jason Weathersby at 8: Before performing Seam Generate Odx, you should have a connection profile adjusted and connected to a database. For ease of segregating these driver-specific properties in the property sheet, one could define them within a propertyGroup element with a group display name like “Connection Properties”.
This is an optional element that an ODA driver may use to store and pass pertinent driver-specific attributes from its designer tool to the run-time driver for the connection.
The BIRT ODA extension point
In the example you will note that the SOAP request is never used. For ease of segregating these driver-specific properties in the property sheet, one could define them within a propertyGroup element with a group display name like “Query Properties”.
BIRT assumes that the data set implementation can provide it at run time. Comments Sign in or register to add and subscribe to comments.
Each property in a display group is treated as a top-level property, whose grouping is not visible, when it is accessed programmatically. These plug-ins are fairly complex, but by referencing the example project, you can extend BIRT’s data-retrieval capabilities.
