cannot locate ejb when the ejb client app and wildfly10 server run on the same machine (it works from a remote machine)
I have the following scenario:
1. a basic wildfly10 server installed on a windows machine under an administrator account with no firewall.
2. I'm using standalone-full.xml as the configuration file and the public interface is bound to <any-address/>.
3. an EAR archive that contains a stateless EJB2 is deployed on Wildfly10. The EJB has only 1 method that returns a string.
When deployed, the EJB is bound to:
java:jboss/exported/SimpleGreeterEARx/SimpleGreeterEJB2xx/TheGreeter!simple.greeter.ejb.Greeter
4. as a client I'm using a standalone java application in which the jboss-ejb-client.properties (which is in the classpath and it is found by the client app)
contains the following:
remote.connections=default
remote.connection.default.host=${server.ip} <-- this could be 10.10.10.153 when the client runs from another machine, or localhost when the client is on the same machine (this comment is not part of the properties file )
remote.connection.default.port=8080
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT=false
Comment: when the ejb client app runs from another machine, an existing wildfly user is used to connect.
5. the ejb client app is very simple. A main method containing the following:
String serviceName = "ejb:SimpleGreeterEARx/SimpleGreeterEJB2xx/TheGreeter!" + Greeter.class.getName();
Properties prop = new Properties();
prop.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
try {
Context context = new InitialContext(prop);
Greeter service = (Greeter) context.lookup(serviceName);
String greeting = service.getGreeting();
System.out.println(greeting);
context.close();
} catch (NamingException e) {
...
} catch (RemoteException e) {
...
}
6. The serviceName string is correct due it it the same as the one listed in server.log when the ejb is deployed.
7. The behavior is the following:
7.1 when running the client from a different machine, the client can call the ejb and get the response form service.getGreeting(); method. (which returns a simple string)
7.2 running the same ejb client app from the same machine where wildfly10 is installed , will throw this error :
