connect websphere MQ 8.0 through JMS adapter

I just want to connect integration server9.8 with websphere MQ 8.0 through JMS adapter or JNDI alias. Just want to know which JNDI Initial Context Factory class should use and what should be the format of JNDI Provider URL.

with MQ 7.5 I am able to connect with com.ibm.mq.jms.context.WMQInitialContextFactory, but it seems this class is not being supported by WMQ as I am not seeing it in 9.0.0.5-IBM-MQ-Install-Java-All.jar.
