Java.lang.ClassCastException when creating a report with two different datasources

[oakrami]

Hello

I am trying to create a report which would pull data from two different datasoruces one being mongo and the other sqlserver .

I can run each reports successfully but when i create a subreport in one and join it to the other i get the following exception:

java.lang.ClassCastException: com.microsoft.sqlserver.jdbc.SQLServerConnection cannot be cast to com.jaspersoft.mongodb.connection.MongoDbConnection

Any help would be greatly appriciated.

Thanks
