javax.naming.NoInitialContextException: Cannot instantiate c

[saeedamer]

I have seen so many posts regarding this problem but none contained a solution.

I am using jboss-3.0.6_tomcat-4.1.18. The jndi.properties file in the server\default\conf directory contains:
------ jndi.properties ----------
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
# Do NOT uncomment this line as it causes in VM calls to go over
# RMI!
#java.naming.provider.url=localhost
--------------------

When I create InitialContext like this:
new javax.naming.InitialContext()

I get following error:
------error------
javax.naming.CommunicationException: Can't find SerialContextProvider
at com.sun.enterprise.naming.SerialContext.getProvider(SerialContext.java:63)
at com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:120)
at javax.naming.InitialContext.lookup(InitialContext.java:347) at Client_1.main(Client_1.java:32)
--------------

And when I setup the JNDI properties as follows and create InitialContext:
--------
props.put ("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
props.put("java.naming.provider.url", "127.0.0.1:1099");

new javax.naming.InitialContext(prop);

I get following error:

It seems that something is missing in the classpath. BTW, I am not relying on the CLASSPATH env variable - I am relying on JBoss to load all the JAR files on its path in "server\default\lib" directory.

I have been banging my head for almost 12 hours now and haven't got anywahere.

Help is greatly appreciated.

Where is your code running? As a component within JBoss or as a client on the outside?

[saeedamer]

I have a standalone client class with main() that creates InitialContex and performs lookup.

[darranl]

Your stand alone application will require the jbossall-client.jar from the client folder to be in its classpath.

The jndi.properties file that you have found is for JBoss internal use only, you need a second copy of the file to use with the client. For the clients jndi.properties file add the java.naming.provider.url entry to select the host that the client will use.

[darranl]

Also I should have said the jndi.properties for the client needs to be on the classpath for the client and it needs to be kept away from JBoss.

[saeedamer]

OK, I'll try as you have suggested and will update on the outcome.

Thanks for all you time and help.

actually I have the same problem, tried out what u said now it says javax.naming.CommunicationException:Receive timed out [Root exception is java.net.SocketTimeoutException:Receive timed out]

Have a look at:

http://wiki.jboss.org/wiki/Wiki.jsp?page=Getquotjavax.naming.NoInitialContextExceptionquot

I guess the java.naming.provider.url that you have specified is not correct. It usually is

java.naming.provider.url=jnp://localhost:1099
