JNDI "Cannot instantiate class: org.jboss.naming.remote.client.InitialContextFactory"
Solution 1
You can use following context to connect. I have tried and tested to set up this.
import java.util.Properties;
import javax.naming.Context;
import javax.naming.NamingException;
public class Program {
public static void main(String[] args) throws NamingException {
Properties jndiProps = new Properties();
jndiProps.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.naming.remote.client.InitialContextFactory");
jndiProps.put(Context.PROVIDER_URL,"remote://localhost:4447");
jndiProps.put(Context.SECURITY_PRINCIPAL, "testuser");
jndiProps.put(Context.SECURITY_CREDENTIALS, "testpassword");
jndiProps.put("jboss.naming.client.ejb.context", true);
Context ctx = new InitialContext(jndiProps);
}
}
Then i got this error
JBREM000200: Remote connection failed: javax.security.sasl.SaslException:
Authentication failed: all available authentication mechanisms failed - Could
not register a EJB receiver for connection to remote://localhost:4447
java.lang.RuntimeException: javax.security.sasl.SaslException: Authentication
failed: all available authentication mechanisms failed.
Then i added the user using add-user.sh.
Successful Handshake message came.

To overcome above error you need to pay attention to two points.
First , You need to have jboss-client.jar in classpath.
Second, according to Jboss version you are using you need to change your provider url.
For JBossAS 5 you should set following properties in environment
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.NamingContextFactory");
env.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
env.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099");
For JBossAS 7 you should set following properties in environment
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
env.put(Context.PROVIDER_URL, System.getProperty(Context.PROVIDER_URL, "remote://localhost:4447"));
env.put(Context.SECURITY_PRINCIPAL, System.getProperty("username", DEFAULT_USERNAME));
env.put(Context.SECURITY_CREDENTIALS, System.getProperty("password", DEFAULT_PASSWORD));
Solution 3
you may need add jboss-client.jar and jboss-ejb3-common-client.jar into your library

I'm using JBoss Server for EJB And I need JNDI in console app to get reference of session bean, console app code looks like this
import java.util.Properties; import javax.naming.InitialContext; import javax.naming.NamingException; public class Program { public static void main(String[] args) throws NamingException { // TODO Auto-generated method stub Properties pr = new Properties(); pr.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory"); pr.put(InitialContext.PROVIDER_URL,"remote://localhost:4447"); InitialContext ic = new InitialContext(pr); } }
when I run the application I get exception
Exception in thread "main" javax.naming.NoInitialContextException: Cannot instantiate class: org.jboss.naming.remote.client.InitialContextFactory [Root exception is java.lang.ClassNotFoundException: org.jboss.naming.remote.client.InitialContextFactory] at javax.naming.spi.NamingManager.getInitialContext(Unknown Source) at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source) at javax.naming.InitialContext.init(Unknown Source) at javax.naming.InitialContext.<init>(Unknown Source) at Program.main(Program.java:14) Caused by: java.lang.ClassNotFoundException: org.jboss.naming.remote.client.InitialContextFactory at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at com.sun.naming.internal.VersionHelper12.loadClass(Unknown Source) ... 5 more
