ConnectionFactory lookup

[itaimaoz]

Hi,

I have a client application that looks up the ConnectionFactory. When the servers is shut down and then restart the lookup fails untill my client is erstarted too.

Here is a simulated behavior:

package jboss.client;

import javax.naming.*;
import java.util.Properties;

public class TestJNDIReconnect {
static String str = "ConnectionFactory";
public static void main(String[] args) {
while (true) {
try {
Properties props = new Properties();

props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

InitialContext ctx1 = new InitialContext(props);

Object ref1 = ctx1.lookup(str);

System.out.println(ref1);

} catch (Exception ex) {
System.err.println(ex.getMessage());
}

try {
Thread.sleep(5*1000);
} catch (InterruptedException iex) {}

}
}
}

The output is:
org.jboss.mq.SpyConnectionFactory@7ee8b8
org.jboss.mq.SpyConnectionFactory@195d80
org.jboss.mq.SpyConnectionFactory@341960
<!-- server went down -->
ConnectionFactory not bound
ConnectionFactory not bound
null
null
null
<!-- server went up-->
null
null
null
null


Thanks,

What version of JBoss are you using?

There is a bug in 3.0.4 that is fixed in 3.0.6 that causes the kind of behavior you describe.

Hi,

Tried with jboss 3.0.6 and it still doesn't work. Can you send more information? Do you have the bug number?

Thanks,

I don't have a bug number handy.

The 'patch' was made in

org.jnp.interfaces.NamingContext.java in the

public Object lookup (Name name)

method.
