remote-naming project for ejb invocation failing to connect to remote host after all configuration is proper

[ravipatil080]

Hi all,

I am using jboss7.2.0.Final and I have deployed myapp.ear file and its running

I have an ejb (stateless) in the service and it is exposed as

java:jboss/myapp/mymodule/HiEjb!com.mycompany.api.HiInterfaceRemote

And My look up configuration is like

     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("jboss.naming.client.ejb.context", true);

     Context ctx = new InitialContext(jndiProps);     

     ejb =  (HiInterfaceRemote) ctx.lookup("myapp/mymodule/HiEjb!com.mycompany.api.HiInterfaceRemote");

And I have following jars in the classpath

jboss-remote-naming-1.0.5.Final.jar

xnio-nio-3.0.7.GA.jar

jboss-ejb-api_3.1_spec-1.0.1.Final.jar

jboss-ejb-client-1.0.0.Beta11.jar

jboss-logging-3.1.0.CR2.jar

jboss-marshalling-1.3.4.GA.jar

jboss-marshalling-river-1.3.4.GA.jar

jboss-remoting-3.2.0.CR8.jar

jboss-sasl-1.0.0.Beta9.jar

jboss-transaction-api_1.1_spec-1.0.0.Final.jar

xnio-api-3.0.0.CR7.jar

But still I am getting error like

I have gone through the documents also and I have implemented in the same way. The links are

https://docs.jboss.org/author/display/AS71/Remote+EJB+invocations+via+JNDI+-+EJB+client+API+or+remote-naming+project

https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI

Am I still missing anything? Please share your points...

Thanks,

Ravi

Do you have add an application user? you should add the credentials as described in the first link. The remote-naming need to have a pswd if the security is enabled for remoting

[ihatetoregister]

As Wolf-Deiter Fink pointed out you need to add a user to the Jboss server . This i think was introduced in Jboss 7 . If you need a good example of  how to add the user to the server then follow this link http://middlewaremagic.com/jboss/?p=1466 .

Client side will change to send username & password to user :

.

  String JBOSS_CONTEXT="org.jboss.naming.remote.client.InitialContextFactory";;

  Properties props = new Properties();

  props.put(Context.INITIAL_CONTEXT_FACTORY, JBOSS_CONTEXT);

  props.put(Context.PROVIDER_URL, "remote://localhost:4447");

  props.put(Context.SECURITY_PRINCIPAL, "testuser");

  props.put(Context.SECURITY_CREDENTIALS, "testpassword");

  context = new InitialContext(props);

.

Server side will be configured to accept username & password :

[userone@localhost bin]$ ./add-user.sh

What type of user do you wish to add?

a) Management User (mgmt-users.properties)

b) Application User (application-users.properties)

(a): b

Enter the details of the new user to add.

Realm (ApplicationRealm) :  ApplicationRealm

Username : testuser

Password : testpassword

Re-enter Password : testpassword

What roles do you want this user to belong to? (Please enter a comma separated list, or leave blank for none) : testrole

About to add user 'testuser' for realm 'ApplicationRealm'

Is this correct yes/no? yes

Added user 'testuser' to file '/home/userone/jboss-as-7.1.0.Final/standalone/configuration/application-users.properties'

Added user 'testuser' to file '/home/userone/jboss-as-7.1.0.Final/domain/configuration/application-users.properties'

Added user 'testuser' with roles testrole to file '/home/userone/jboss-as-7.1.0.Final/standalone/configuration/application-roles.properties'

Added user 'testuser' with roles testrole to file '/home/userone/jboss-as-7.1.0.Final/domain/configuration/application-roles.properties'

.

.

I faced the same issue :-) I hope this helps and adds to what Wolf has told you to do .

I don't have any application user added in the Jboss server. So I am not passing principal and password. Do I need to have the application user in order to use remote-naming project? I dont think so.

[wdfink]

If you did not change the default configuration the remoting connector is secured and you need to add an application use.

Other option is to look into the remoting subsystem configuration and remote the security-realm, in that case the connection is not longer secured and you can connect without credentials.
