Problems using Cassandra Connector in JasperReports Server

0

 

Hello.  I have installed the iReport plugin for the Cassandra Connector and successfully created a report that accesses my Cassandra database.  Now I want to execute my report on the Jasper Server.  I copied the Cassandra jars to the appropriate folders and followed the instrucitons for renaming the hive*.jar files in order to prevent the thrift conflict with the Cassandra connector.  After renaming the hive jars the Jasper Server fails to start.  If I leave the hive*.jars, I can load my jrxml onto the server but I get the following error when trying to run:

 

com.jaspersoft.jasperserver.api.JSException: java.lang.IncompatibleClassChangeError: Implementing class at com.jaspersoft.jasperserver.api.engine.jasperreports.service.impl.EngineServiceImpl.fillReport(EngineServiceImpl.java:497) at com.jaspersoft.jasperserver.api.engine.jasperreports.service.impl.EngineServiceImpl.executeReportUnitRequest(EngineServiceImpl.java:1666) at com.jaspersoft.jasperserver.api.engine.jasperreports.domain.impl.ReportUnitRequest.execute(ReportUnitRequest.java:67) at com.jaspersoft.jasperserver.api.engine.jasperreports.service.impl.EngineServiceImpl.execute(EngineServiceImpl.java:399) at com.jaspersoft.jasperserver.war.action.ViewReportAction.executeReport(ViewReportAction.java:637) at com.jaspersoft.jasperserver.war.action.ViewReportAction.executeReport(ViewReportAction.java:523) at com.jaspersoft.jasperserver.war.action.ViewReportAction.runReport(ViewReportAction.java:371) at  ...

 

I am running Cassandra 1.1.5 and cassandra-connector-for-jaspersoft-bin-0.5.1.  Any help you can provide is appreciated.

What errors do you get when you cannot restart your server? I confirm that it's working well for me in JRS 4.7 and JRS 5.0.

I updated the wiki docs to be more precise. Maybe that will help point the way to whatever the issue is.

Had the same issue. The Cassandra Connector v0.5.1 was missing json-org-1.0.jar. Download it, put it into WEB-INF/lib and restart the server.
