Hello there,
I need desperately your help: I've implemented a simple HttpServlet
which runs in EmbededTomcat engine. In the Constructor of the Servlet I
try to create an InitialContext and after that to bind the servlet under
a specified name.
// Servlet constructor
public CallbackChannel() {
....
try {
System.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url", "localhost:1099");
InitialContext jndiContext = new InitialContext();
jndiContext.bind("java:/CallbackChannel", this);
} catch (Exception e) {
e.printStackTrace();
}
....
}
The Exception that I receive when I try to do new InitialContext ...
javax.naming.NoInitialContextException: Cannot instantiate class:
org.jnp.interfaces.NamingContextFactory. Root exception is
[EmbeddedTomcat] java.lang.ClassNotFoundException:

My environment has in the CLASSPATH variable the following jars:
...
set
CLASSPATH=%CLASSPATH%;c:\programme\java\jboss-2.0\client\jboss-client.jar
set
CLASSPATH=%CLASSPATH%;c:\programme\java\jboss-2.0\client\jnp-client.jar
set CLASSPATH=%CLASSPATH%;c:\programme\java\jboss-2.0\lib\ext\ejb.jar
...
The deployment procedure is perfect and doesn't generate some
exceptions. Also I could contact the EmbededTomcat on the configured
port and works.
Any idea, suggestions ?
Thank you in advance.
bye.
