It simply means You have a NPE AND You need to initialize the jndiContext and optionally pass in the environmental configuration variables to the constructor:

Context jndiContext = new InitialContext(); // use default environmental vars
or
jndiContext = new InitialContext(env); // env - configuration property file with env. variables.

Hi,

I am used "Context jndiContext = new InitialContext();" class to initialize the JNDI. I am getting below mentioned error.

run:
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
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645)
at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:325)
at javax.naming.InitialContext.lookup(InitialContext.java:392)
at view.SimpleMessageBeanClient.<init>(SimpleMessageBeanClient.java:30)
at view.SimpleMessageBeanClient.main(SimpleMessageBeanClient.java:54)


I do not know how to configure property file with environment variables. so i did not tryied that.


Could you please advice on this to solve.

The standard set of JNDI properties are:


java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming.client


These values may vary depending on your version of JBoss. They should be defined in a file called jndi.properties which is on the classpath when the client code runs.

Hi,
I am not using to use JBOSSMQ. i am using JMS and deploying under JBOSS AS. I think we have to give the above mentioned JNDI config only for JBOSSMQ. may i correct?

i need to connect via my own connection factory and Queue. How to do this.

could you please advice on this.
