Olap4j with Splunk DBConnect

[MikaJustasACN]

Hello Everyone,

I am trying to use Olap4j driver with DBConnect towards Olap based database (SAP BW). When I try to load the driver, I get this in logs:
"java.lang.NoClassDefFoundError: org/olap4j/OlapDatabaseMetaData".

File structure:
../drivers/olap4j-xmla-1.2.0.jar
../drivers/olap4j-xmla-1.2.0-libs/olap4j-1.2.0.jar

Any ideas on the error? If I look into the source code on olap4j-1.2.0.jar it does contain class definition for OlapDatabaseMetaData.

I have updated my JRE to JDK, the error has changed to
"java.lang.NoClassDefFoundError: org/olap4j/PreparedOlapStatement"
