Hello, i'm new!!!

I'm approacing for the first time with JBoss and EJB; currently i'm running JBOSS
6.0 final, EJB 3.0 ( i chose this when i created my project - i don't want to use EJB
3.1 for now ), Eclipse Helios. Everything should be configured, i hope.

That's what i have done till now:

Created a +CalculatorBean+ and his interface +CalculatorRemote+ under the package
+mycalcBean+;
Created a +CalculatorClient+  under the package +mycalcClient+;

both in the same EJB project +MyProjectEJB3.0.+

The client is a Java simple main that looks up for my bean and use a couple of his methods
and runs as a Java application.

I have to set environment properties in my client and pass +env+ to my context.lookup:

*+     Hashtable<String, String> env = new Hashtable<String, String>();+*
*+                     env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");+*
*+                     env.put(Context.PROVIDER_URL, "localhost:1099");+*
*+                     env.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming.client");+*
+                     InitialContext ctx = new InitialContext(*env*);+
+                     Object obj = ctx.lookup(CalculatorBean.class.getSimpleName() +
"/remote"/*"CalculatorBean/remote"*/);+

or i get the NOINITIALCONTEXT error. 
Why i need to do this when a lot of tutorials don't? Moreover i would prefer to use
@EJB to look for my bean.
I have read a lot of things that tell about the jndi.properties file. Well, that's my
file under JBOSS_HOME\server\default\conf:

*# DO NOT EDIT THIS FILE UNLESS YOU KNOW WHAT YOU ARE DOING*
*#*
*java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory*
*java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces*

I also tryed to put this file in the path where i have my client and in the CLASSPATH of
my JDK.

Nothing worked. Why my client can't read this default conf file?

One last question:
if i change position to my client, putting it into a different project ( for example:
+MyProjectEJB3.0Client+ ) the compiler doesn't see the +import project.mycalcBean.*+ 
How to do that?

thank you for your understanding and help!!!
