< To: Report Developer Examples (BIRT)
BIRT 4.2.2 and later supports 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 copy the Hector client library JAR files to the appropriate folder. You can download the JAR files from here.
Installing the Hector client library JAR files for use with BIRT Designer
Copy the JAR files to the org.eclipse.birt.me.prettyprint.hector_<version>/lib/ folder and then restart BIRT Designer. If you do not copy the JAR files, the following error message appears when you select the Cassandra Scripted Data Source in the New Data Source wizard:
Unable to find Hector client library jars to support Cassandra Scripted Data Source
Installing the Hector client library JAR files for use with the BIRT runtime deployment application
For OSGi BIRT runtime deployment, copy the JAR files to the org.eclipse.birt.me.prettyprint.hector_<version>/lib/ folder and restart the runtime deployment application. There is a known issue unrelated to Cassandra scripted data sources that may cause a ClassNotFound exception. Copy the commons-logging-api-1.1.1.jar to the birt/WEB-INF/lib/ folder resolve this problem.
For non-OSGi BIRT runtime deployment, copy the JAR files to the <installation_folder>/webapps/birt_runtime/scriptlib/ folder and restart the runtime deployment application.
If you do not copy the JAR files, the following error message appears at runtime:
Caused by: org.eclipse.birt.core.exception.CoreException: Error evaluating Javascript expression. Script engine error
