I recently migrated my application from JBoss AS 4.2.1 to JBoss AS 7.1, but I am not being able to access the application vua http request since I am getting the below error:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.

回答1:
Add "Dependencies: org.jboss.remote-naming" to META-INF/manifest.mf of your .WAR file. This will load org.jboss.remote-naming module and eliminate "Failed instantiate InitialContextFactory" exception. Details here: https://docs.jboss.org/author/display/AS71/Class+Loading+in+AS7
use jboss-ejb-client.properties file and place it to WEB-INF folder vs content like this:
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=your host
remote.connection.default.port=your port
remote.connection.default.username=you user
remote.connection.default.password=you password
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
and lookup this way:
Properties jndiProps = new Properties();
jndiProps.puy(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
jndiProps.put(Context.SECURITY_PRINCIPAL, JBOSS_USER);
jndiProps.put(Context.SECURITY_CREDENTIALS, JBOSS_PWD);
jndiProps.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
jndiProps.put(Context.PROVIDER_URL, "remote://yourhost:yourport");
InitialContext initialContext = new InitialContext(jndiProps);
YourRemote remote=(YourRemote)initialContext.lookup("java:/app-name/ejb-jar-name/YourBean!package.YourRemote");
For details see: https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI
Good luck!

From post above... "Add "Dependencies: org.jboss.remote-naming" to META-INF/manifest.mf of your .WAR file."
Thanks so much for the above help. It got me a step closer to migrating to JBoss EAP 6.
An alternative to above, if you have a War file that has to be deployed on non-JBoss servers, is to add the following to the jboss-deployment-structure.xml file.
That has the benefit of separating out the JBoss specific elements to their own JBoss specific files.
<sub-deployment name="yourWebApp.war">
<dependencies>
<module name="org.jboss.remote-naming" />
</dependencies>
</sub-deployment>
regards, Owen
