Cassandra Scripted Data Source (BIRT)
< To: Report Developer Examples (BIRT)
BIRT Designer and runtime deployment packages now support scripted data source connections for use with Cassandra distributions, including:
- Apache Cassandra
- Datastax Cassandra Community
- Datastax Cassandra Enterprise
BIRT connects to and queries a Cassandra data source using the Hector API. You must install the Hector client library JAR files in the appropriate folder. You can download the JAR files from here.
Installing the Hector client library JAR files for use with BIRT Designer
org.eclipse.birt.me.prettyprint.hector_<version>/lib folder, and then restart BIRT Designer or the runtime deployment application.

This example was built and tested with BIRT 2.2 RC0.
This example accesses a city locator from zip code web service located here: http://www.webservicex.net/uszip.asmx?WSDL.
The above URL is entered in the data source WSDL URL property. The data set is set to the getInfoByZIP Method. The default SOAP request template generated by the driver supplies one data set parameter for the zip code. It is important to remember any part of the SOAP request can be modified. To link a portion of the SOAP request to a data set parameter use the
syntax, where symbol is the name of the data set parameter. In the data set editor this parameter can be linked to a report parameter. In this example symbol is linked to the report parameter zipcode.
Once the response is returned, it is parsed just like the XML data source using XPath syntax.
