#89 UnsupportedOperationException

[M. Rahil Rafiq]

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.
