I'm trying to do Remote EJB calls to my Wildfly 10/JBoss 7 EAP server, but keep getting Invalid User error messages on my Wildfly server (my EJB is called LoginManager):
23:04:02,872 ERROR [org.jboss.as.ejb3.invocation] (default task-6) WFLYEJB0034: EJB Invocation failed on component LoginManager for method public abstract java.lang.String ejbs.LoginManagerRemote.echo(java.lang.String): javax.ejb.EJBAccessException: WFLYSEC0027: Invalid User
at org.jboss.as.ejb3.security.SecurityContextInterceptor$1.run(SecurityContextInterceptor.java:69)
at org.jboss.as.ejb3.security.SecurityContextInterceptor$1.run(SecurityContextInterceptor.java:49)
at org.jboss.as.ejb3.security.SecurityContextInterceptor.processInvocation(SecurityContextInterceptor.java:97)
I've added my user to the application-users.properties file using the add-user.sh/bat scripts.
I've tried putting in breakpoints in the Wildfly server itself in the SecurityContextInterceptor class on line 54 and see that the principal is null:
if (holder.skipAuthentication == false) {
holder.securityManager.authenticate(holder.runAs, holder.runAsPrincipal, holder.extraRoles);
I'm not entirely sure if this runAs or runAsPrincipal is the principal/credentials passed by the remote EJB invocation, but I suspect it might be responsible for my problem.
I'm calling the remote ejb as:
Properties p = new Properties();
p.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
final Context context = new InitialContext(p);
LoginManagerRemote ejb = (LoginManagerRemote) context.lookup("ejb:ear-1.0/ejbs-1.0//LoginManager!ejbs.LoginManagerRemote");
return ejb.echo("test");
with my jboss-ejb-client.properties as:
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=localhost
remote.connection.default.port=8080
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.conncetion.default.connect.options.org.xnio.Options.SASL_DISALLOWED_MECHANISMS=JBOSS-LOCAL-USER
remote.connection.default.username=test
remote.connection.default.password=test
Am I doing something wrong? Am I missing something obvious somewhere? What do I need to do to successfully call a remote EJB?
There's a typo in your jboss-ejb-client.properties
remote.conncetion.default.connect.options.org.xnio.Options.SASL_DISALLOWED_MECHANISMS=JBOSS-LOCAL-USER
Should be remote.connection.default.connect.options etc etc

Dears,
I'm trying to call ejb3 in jboss 5.0.1 from Wildfly 10 or EAP 7.
My code:
final Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
env.put("java.naming.factory.url.pkgs", "org.jboss.ejb.client.naming");
env.put(Context.PROVIDER_URL, "remoting://localhost:1099");
env.put("org.jboss.ejb.client.scoped.context", "true");
InitialContext initialContext = new InitialContext(env);
TestBeanRemote remote = (TestBeanRemote) initialContext.lookup(
"ejb:TestEar/TestBean/TestBean!com.test.TestBeanRemote");
but it says:
Exception in thread "main" java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling [appName:BilllingFacadeCallbackEAR, moduleName:BilllingFacadeCallback, distinctName:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext#3b088d51

Is there any solution to call legacy jboss without old jars?
There is a legacy subsystem for this but I don't know its current status.
https://github.com/jboss-set/jboss-as-legacy
The CORBA standard defines an "across the wire" standard for making remote method calls called IIOP or "Internet Inter-ORB Protocol".
You need to set up to use CORBA IIOP in order to make platform independent remote EJB calls.
Therefore, you need to:
configure JBoss 5 so that it can handle incoming IIOP calls;
configure WildFly 10/EAP 7 to make outgoing EJB invocations using IIOP.
There is some information on this in the WildFly 10 EJB3 Reference Guide although I'm not sure how up to date that is.
The issue is normally caused by a transaction reaching it's timeout value.
So it may be that the application logic is correctly handling the scenario in this case and is not attempting to retry activity
It can have several issues :
connection: Connection broken
security : user/pass invalid
EJB missing: connected, but ejb is not there
SSL
Ports
IP Address
JBoss maintains a persistent connection to the other server, so when the client sees this message it means there is no connection to a server that has the ejb you are trying to call, so a message will be logged when the connection fails to the other server.
Caused by: java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling
Can you clarify the below:
1# is your EJBs deployed on jboss 5.0.1?
2# You are invoking the EJBS from Wildfly 10 or EAP 7, means your client is deployed in Wildfly 10 or EAP 7?
I already have a integration-test phase, when I ran the selenium tests. I also want to run some unit tests in this phase, because the app is too much complex and have a lot of dependencies between his modules (a hell), so, after a week fighting against OpenEJB and Arquillian, I believe that this would be easier.
The thing is: how do I made it work?
I have the instance already running, if I instantiate an InitialContext and try to lookup some bean, I got an exception telling me that I have not set the java.naming.initial.factory, and I don't know what to put in there.
I'm also complaining about the annotated beans.
Suppose a Bean like this:
#Stateless
public class ABeanImpl implements ABean {
#EJB
private BBean;
}
Will the container automatically get right the BBean?
Thanks in advance
How to connect to JBoss 7.1 remote JNDI:
Here is the code snippet that I use for JBoss 7.1:
Properties props = new Properties();
String JBOSS_CONTEXT = "org.jboss.naming.remote.client.InitialContextFactory";
props.put("jboss.naming.client.ejb.context", true);
props.put(Context.INITIAL_CONTEXT_FACTORY, JBOSS_CONTEXT);
props.put(Context.PROVIDER_URL, "remote://localhost:4447");
props.put(Context.SECURITY_PRINCIPAL, "jboss");
props.put(Context.SECURITY_CREDENTIALS, "jboss123");
InitialContext ctx = new InitialContext(props);
Resolution of ambiguous ejb references:
According to JBoss EJB 3 reference, if at any level of your EJB environment (EJB/EAR/Server) are duplicates in used interfaces, exception will be thrown during resolution of injected beans.
Based on above, if you have got a reference to EJB bean which interface:
has two implementations in your EJB module (JAR/WAR) - exception will be thrown
has two implementations in your application (other EJB JAR's in same EAR) - exception will be thrown
has two implementations, one in module with bean ABeanImpl, second somewhere else - implemetation from current module is used.
My application is deployed on JBoss 7.1 (standalone).
I am getting an exception on the following line:
MBeanServerConnection server = MBeanServerLocator.locateJBoss();
The exception is:
JBoss: java.lang.IllegalStateException: No 'jboss' MBeanServer found!
That code above worked fine when the app was deployed on JBoss 5.
From what I was reading online, the code is supposed to work only when it's called from the same JVM in which the MBeanServer was created. Otherwise it's a remote call and I have to use JNDI. But is it not a local call (same JVM - i.e. the JBoss JVM)? How did it work on JBoss 5 then?
How do I make it work on JBoss 7.1 standalone, without changing this specific code?
Here is the solution:
https://community.jboss.org/thread/221708
Quote:
Above problem is dueto locateJboss implementation that is compatible with older version of Jboss. The MBeanServer used by JBoss 7 (by default) is the platform MBeanServer. The class name iscom.sun.jmx.mbeanserver.JmxMBeanServer and the default domain is DefaultDomain. Accordingly, you can simply use:
java.lang.management.ManagementFactory.getPlatformMBeanServer()
Alternatively:
for(MBeanServer server: javax.management.MBeanServerFactory.findMBeanServer(null)) {
if("DefaultDomain".equals(server.getDefaultDomain())) return server;
}
throw new Exception("Failed to locate MBeanServer");
On another note, jboss.system:type=ServerInfo object name doesn't work in AS 7.1 I had to use JVM specific parameters to nail down to MBean attributes. 'java.lang:type=Memory' and attribute as 'HeapMemoryUsage'.
I am using jboss-5.0.1 GA.
I am trying to invoke EJB deployed on remote JBoss server from my local EJB using JNDI.
I have included the remote interfaces jar file in my local EJB project's class path. I have as well added jnp-client.jar, jboss-ejb3-client.jar in my class path.
I have started JBoss on remote machine with -b 0.0.0.0 flags to ensure it accepts remote connections.
Here is the code.
SatheBeanRemote sbr = null; //Is the remote interface for the remote bean
Properties p = new Properties();
p.put(Context.PROVIDER_URL, "jnp://10.73.17.76:1099"); //remote Jboss IP
p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
Context context;
try {
context = new InitialContext(p);
sbr = (SatheBeanRemote) context.lookup("RemoteEAR/SatheBean/remote");
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I am getting the below exception.
javax.ejb.EJBException: Unexpected Error
java.lang.NoClassDefFoundError: com/netapp/beans/SatheBeanRemote
at com.netapp.balaji.greeting.GreetingBean.sayGreeting(GreetingBean.java:78)
Can anyone help me point out the issue ?
Probably, You have to add EJB Project in your client folder's class path, It may resolve the problem
I am new to EJB3 and am missing something when it comes to accessing a #Remote #Stateless bean deployed as an ejb module inside an ear file. I want to access a remote bean in lima.ear from soup.ear.
Here is what I am doing now (somewhat abbreviated):
//deployed under lima.ear
#Remote
#Stateless
public interface LimaBean {
String sayName();
}
I want to put LimaBean in the Soup:
//deployed in soup.ear
#Stateless
public class Soup implements SoupLocal {
#EJB
private LimaBean limaBean;
public String taste() {
return limaBean.sayName();
}
}
When I start JBoss I get the following error:
java.lang.RuntimeException: could not resolve global JNDI name for #EJB for container Soup: reference class: com.example.LimaBean ejbLink: not used by any EJBs
I have had a hard time finding out what this ejbLink is about, if that is the right path to go down.
If I deploy LimaBean as a jar file in jboss then everything works great!
I ran accross an article that had a section called "2.5.3. References between beans in different jars and different ears"
(http://jonas.ow2.org/doc/howto/jboss2_4-to-jonas3_0/html/x111.html)
Example of jboss.xml file for SB_BrowseRegions:
<jboss>
<session>
<ejb-name>SB_BrowseRegions</ejb-name>
<ejb-ref>
<ejb-ref-name>ejb/Region</ejb-ref-name>
<jndi-name>protocol://serverName/directory/RegionHome</jndi-name>
</ejb-ref>
</session>
</jboss>
If I touch the soup.ear, after JBoss starts up then it deploys fine, so I am assuming I need to specify a dependency like the above article says.
But even after it deploys then I get an error when accessing the remote LimaBean:
Caused by: java.lang.IllegalArgumentException: Can not set com.soup.LimaBean field com.soup.Soup.limaBean to $Proxy147
at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:146)

at java.lang.reflect.Field.set(Field.java:657)
at org.jboss.injection.JndiFieldInjector.inject(JndiFieldInjector.java:115)
... 49 more
I have tried a few things but, if anyone can point me in the right direction about this I would appreciate it.
It looks like the JNDI properties need to be set as if it were a remote client outside of the app server because of the ear isolation we have setup.
properties.put(Context.PROVIDER_URL, url);
InitialContext ctx = new InitialContext(properties);
Just specify the URL for the InitialContext and that should do the trick.
