    I am using c3p0 with olap4j to create connection pool in tomcat.

    I am using the following jars

    c3p0-0.9.5-pre5.jar
    mchange-commons-java-0.2.6.2.jar
    olap4j-1.2.0.jar
    olap4j-1.2.0-sources.jar
    olap4j-tck-1.2.0.jar
    olap4j-xmla-1.2.0.jar
    xerces-2.9.1.jar

    I have JNDI resource in context.xml like this...

    <Resource name="jdbc/olap" auth="Container" type="com.mchange.v2.c3p0.ComboPooledDataSource" factory="org.apache.naming.factory.BeanFactory" driverClass="org.olap4j.driver.xmla.XmlaOlap4jDriver" jdbcUrl="jdbc:xmla:Server=http://OLAP-DB/OLAP/msmdpump.dll;Catalog=Clm_Data" user="***" password="***"/>

    I am getting the following exception.

    Anyone have any idea?

      It’s quite simple - getWarnings is not implemented in the XMLA driver. Can you log a bug.
