Failure to Instantiate DnsContextFactory

created by Shelley Baker in JBoss AS7 Development - View the full discussion

When attempting to create a new InitialDirContext using the com.sun.jndi.dns.DnsContextFactory, the following exception occurs:

Caused by: javax.naming.NamingException: Failed instantiate InitialContextFactory com.sun.jndi.dns.DnsContextFactory from classloader ModuleClassLoader for Module "deployment.test-case.ear.test-web.war:main" from Service Module Loader

Here is my relevant code snippet:

Hashtable env = new Hashtable();
env.put("java.naming.factory.initial", "com.sun.jndi.dns.DnsContextFactory");
env.put("java.naming.authoritative", "false");
env.put("com.sun.jndi.dns.recursion", "true");
env.put("com.sun.jndi.dns.timeout.initial", timeoutProp);
env.put("com.sun.jndi.dns.timeout.retries", "1");
env.put("java.naming.provider.url", providerProp);
DirContext ctx = new InitialDirContext(env);

I found this thread which seemed very similar to the problem that I am running into, but setting the "jboss.modules.system.pkgs" property to "com.sun.jndi.dns" had no effect.

I'm running JBoss AS 7.0.0.Final, using the 1.6.0_26 JRE.

Any suggestions on how to resolve this problem would be greatly appreciated.
