Jboss JNDI properties under Tomcat

[haithamnor]

Hi. I am using JBOSS 4.2.3 and Tomcat 7.

so while lookup  JNDI

(

prop.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");

prop.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");

)

from client application under Tomcat

i got the following Error 

<< Cannot instantiate class: org.jnp.interfaces.NamingContextFactory >>

Any help?

Thx

prop.setProperty("java.naming.provider.url", "192.168.0.18:1099");
