fOlks..

I am trying to implement a Publish / Subscribe module using MQ JMS APIs.

am using JNID to look up configured TCF and T JNDI Objects.

following are the configured objects

InitCtx> display T(ivtT)

BROKERDURSUBQ(SYSTEM.JMS.D.SUBSCRIBER.QUEUE)
TOPIC(MQJMS/PSIVT/Information)
PERSISTENCE(APP)
CCSID(1208)
TARGCLIENT(JMS)
ENCODING(NATIVE)
BROKERCCDURSUBQ(SYSTEM.JMS.D.CC.SUBSCRIBER.QUEUE)
PRIORITY(APP)
EXPIRY(APP)
VERSION(1)

InitCtx> display TCF(ivtTCF)

STATREFRESHINT(60000)
BROKERCONQ(SYSTEM.BROKER.CONTROL.QUEUE)
QMANAGER()
BROKERPUBQ(SYSTEM.BROKER.DEFAULT.STREAM)
BROKERVER(V1)
USECONNPOOLING(YES)
MSGBATCHSZ(10)
BROKERQMGR()
BROKERSUBQ(SYSTEM.JMS.ND.SUBSCRIBER.QUEUE)
TRANSPORT(BIND)
PUBACKINT(25)
SYNCPOINTALLGETS(NO)
POLLINGINT(5000)
BROKERCCSUBQ(SYSTEM.JMS.ND.CC.SUBSCRIBER.QUEUE)
VERSION(2)

am getting an error as follows when I try to look up for TCF.

"javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial"

what could be the problem?

I have the rt.jar in the classpath that has the Context.class and the InitialContext.class. I have the fscontext.jar in the classpath for "com.sun.jndi.fscontext.RefFSContextFactory" to be used as the Initial_Context_Factory. My Provider_url is "file://172.30.66.14/C:/Program Files/IBM/MQSeries/Java".

what's wrong in my set up?
I have been trying out all I could think on this..
but nothing seem to solve my prob so far..

help me out guys..
I just have some mroe time left to get things up and running..

thankx in advance..

Can you post the code that creates the JNDI context and attempts to access it. It looks very, very much like a JNDI problem.
