Hi, I am new to JMS and Websphere server and I am trying to access a JMS queue configured on Websphere Application Server 8 from my Java code. But I am getting the exception mentioned below:
Start.....
*******null********
Exception in thread "main" java.lang.NoClassDefFoundError: com.ibm.ws.naming.util.CommonHelpers

... 7 more

PFB the complete code:


I have also added required jars: com.ibm.ws.messagingClient.jar
com.ibm.ws.sib.client_ExpeditorDRE_8.0.0.jar
com.ibm.ws.sib.client.thin.jms_8.0.0.jar
com.ibm.xml.thinclient_8.0.0.jar

I have made JMS configurations in the Websphere Application Server using the steps given at the link below: http://pic.dhe.ibm.com/infocenter/iisinfsv/v8r1/index.jsp?topic=/com.ibm.swg.im.iis.infoservdir.user.doc/topics/t_isd_user_setting_up_jms_in_was.html

Can someone please help me with this?

Error you posted states clearly you are missing some library. Try and include all client jars, not only the ones you mentioned, and rerun your program.
