Did you ever figure this problem out?

I have the same issue and can seem to get past it!

Hi,

I figured this out - at least my installation which JBoss 3.x

the following lines of code is required..

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost:1099");
//get naming context
Context ctx = new InitialContext(env);

Sounds like you have a socket timeout. Here are the JNDI properties I've been using. The last two settings deal with socket timeout so it might be worth tryiing it out.

jndi properties

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost:1099/
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
# The jnp protocol socket factory class
jnp.socketFactory=org.jnp.interfaces.TimedSocketFactory
# The TimedSocketFactory connection timeout in milliseconds(0 == blocking)
jnp.timeout=0
# The TimedSocketFactory read timeout in milliseconds(0 == blocking)
jnp.sotimeout=0

Hi,

I thought this was the solution, but it isn't... :-(

The strange thing is, it happens only when i have a quite high load.. this is the situation.

I have JBoss instances in one partition (Default partition)

On these instances, I deployed a Stateful SessionBean.

When call some methods on it, it seems to work.
When I start 30 threads that call the same methods, some of them get the following exception(s) during creation of the InitialContext.
(Maybe good to know, It happens in both cases: when both servers are running AND when only one server runs)

This is how I create my InitialContext:

Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "10.0.0.57, 10.0.0.65");
// The TimedSocketFactory connection timeout in milliseconds(0 == blocking)
p.put("jnp.socketFactory","org.jnp.interfaces.TimedSocketFactory");
p.put("jnp.timeout","0");
// The TimedSocketFactory read timeout in milliseconds(0 == blocking)
p.put("jnp.sotimeout","0");

The Exceptions I get:

javax.naming.CommunicationException: Receive timed out. Root exception is java.io.InterruptedIOException: Receive timed out
at java.net.PlainDatagramSocketImpl.receive(Native Method)
at java.net.DatagramSocket.receive(DatagramSocket.java:387)

OR
