[Microcontainer] - Programmatically getting JNDI Context
by amit.bhayani＠jboss.com
I have a app which is on MBeans as of now. I am trying to port to MC. One of the requirements I have is one of the MBeans creates POJO's and register with JNDI as and when required. In MC I was thinking this can be replaced by a Factory that gives new instance of POJO bean when 'newInsatnce' is called. However the requirement is such that it should get registered with JNDI for latter look-up. This app should be flexible to be deployed in JBoss AS and hence use JBoss JNDI or standalone and hence use MockInitialContextFactory.
I have seen JndiDecoratedTestCase and it registers the beans to JNDI, but JNDI name is predefined here. While in my app the JNDI name is calculated at runtime. I am wondering how can this be achieved?
Can I get access to JNDI Contex programmatically which has INITIAL_CONTEXT_FACTORY set to MockInitialContextFactory in standalone and set to JBoss context in JBoss environment? This way I can use factory to get bean and then code in MBean for JNDI registration.
Thanks in advance.

[Beginners Corner] - No InitialContext Exception
by denisputnam
Hi,
I am reading the "Enterprise JavaBeans 3.0" book from O'Reilly, and I am getting the following error. I am using JBoss 4.x and JDK 6.0 with
MyEclipse. I have included the error and the code.
I apologize for all the text, but I don't know what you need to tell me what to do. Thank you for any help.
-Denis
The Client code:
public static Context getInitialContext() throws javax.naming.NamingException
{
Properties p = new Properties();
// Specify the JNDI properties specific to JBOSS
p.put( Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory" );
p.put( Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" );
p.put( Context.PROVIDER_URL, "jnp://localhost:1099" );
InitialContext initContext = new InitialContext(p);
return initContext;
}
The TravelAgent Bean code:
package com.titan.travelagent;

}
public Cabin findCabin( int pKey )
