我尝试在WebsphereMQ 7.5.0中配置InitialContext，我的JmsAdmin.config文件就像：
INITIAL_CONTEXT_FACTORY: com.ibm.websphere.naming.WsnInitialContextFactory
PROVIDER_URL: corbaloc:iiop:localhost:2810
当我在Linux中运行JmsAdmin时，我得到以下异常：
[appuser@integration2 bin]$ ./JMSAdmin -v
Picked up JAVA_TOOL_OPTIONS: -Dorg.omg.CORBA.ORBClass=com.ibm.CORBA.iiop.ORB

javax.naming.ServiceUnavailableException: A communication failure occurred while
attempting to obtain an initial context with the provider URL:

information in the URL is correct and that the target name server is running.
A bootstrap address with no port specification defaults to port 2809. Possible
causes other than an incorrect bootstrap address or unavailable name server
include the network environment and workstation network configuration.
