I am trying to call my EJBs in a remote environment and I am using Wildfly as my container.
Apologies but this is my first time trying to call an EJBs in a remote way.
I have used the instructions below for invoking EJBs in Wildfly. https://docs.jboss.org/author/display/WFLY8/EJB+invocations+from+a+remote+client+using+JNDI
But, I am having an error calling these EJBs and I do not know what is wrong to my configuration.
See error stack trace below:

My interface in both remote server and client side:
public interface ImageManipulateService{
public UploadedImage manipulate(UploadedImage img) throws IOException, Exception;
}
My EJB in the remote server (Wildfly):
@Service
@Stateless
@Remote(ImageManipulateService.class)
public class GrayscaleImageServiceImpl implements ImageManipulateService{
@Override
public Object manipulate(Object img) throws IOException, Exception {
....
}
}
Client side:
jboss-ejb-client.properties
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host = localhost
remote.connection.default.port = 9090
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
I have been running my client in tomcat server (:8080) and I'm trying to invoke the EJBs on Wildfly via localhost:9090. (is it correct?)
I also have the jboss-client.jar included in my Maven dependencies. I used version 4.0.2. (jboss-client-4.0.2.jar)
I made a java class that would call the lookup of services in order to conveniently call them.
public class RemoteContext {
public static ImageManipulateService lookupRemoteGrayscaleService() throws NamingException {
Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
Context context = new InitialContext(jndiProperties);
String appName = "";
String moduleName = "ImageService-1.0-SNAPSHOT";
String distinctName = "";
String beanName = "GrayscaleImageServiceImpl";
String viewClassName = "com.project.imageservice.ImageManipulateService";
return (ImageManipulateService) context.lookup("ejb: " + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);
}
public static ImageManipulateService lookupRemoteTimestampService() throws NamingException {
Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
Context context = new InitialContext(jndiProperties);
String appName = "";
String moduleName = "ImageService-1.0-SNAPSHOT";
String distinctName = "";
String beanName = "TimestampImageServiceImpl";
String viewClassName = "com.project.imageservice.ImageManipulateService";
return (ImageManipulateService) context.lookup("ejb: " + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);
}
}
