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?

Per my question Apache Geode Web framework I've checked through various spring guides from here and spring data geode samples from here and written a short spring data geode application but it cannot connect to the remote GFSH started Geode locator. The Application class is:
package cm;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.gemfire.config.annotation.ClientCacheApplication;
import org.springframework.data.gemfire.config.annotation.ClientCacheApplication.Locator;
import org.springframework.data.gemfire.config.annotation.EnablePdx;
import org.springframework.data.gemfire.repository.config.EnableGemfireRepositories;
#SpringBootApplication
#ClientCacheApplication(name = "CmWeb", locators = #Locator, subscriptionEnabled = true)
#EnableGemfireRepositories(basePackageClasses= {CmRequest.class})
#EnablePdx
public class CmWeb {
public static void main(String[] args) {
SpringApplication.run(CmWeb.class, args);
}
}
and in the resources directory application.properties I've set up the remote locator:
# Configure the client's connection Pool to the servers in the cluster
spring.data.gemfire.pool.locators=1.2.3.4[10334]
Build and run the application and it discovers the locator (which it returns as the server name)
[Timer-DEFAULT-2] o.a.g.c.c.i.AutoConnectionSourceImpl : AutoConnectionSource discovered new locators [UAT:10334]
A couple of seconds later it throws the error:
[Timer-DEFAULT-2] o.a.g.c.c.i.AutoConnectionSourceImpl : locator UAT:10334 is not running.

After a lot of investigation I thought it was that the spring data geode client expects a spring boot geode server according to Connecting GemFire using Spring Boot and Spring Data GemFire and so I downloaded the ListRegionsOnServerFunction jar and deployed it on the GFSH server get the same result (have not yet restarted the server...) but that causes the same error condition.
If by Spring-Data-Gemfire - Unable to contact a Locator service. Operation either timed out or Locator does not exist I try and change the application.properties from
spring.data.gemfire.pool.locators=1.2.3.4[10334]
to
spring.gemfire.locators=1.2.3.4[10334]
or other variations then the app can't find the remote locator and throws:
[Timer-DEFAULT-3] o.a.g.c.c.i.AutoConnectionSourceImpl : locator localhost/127.0.0.1:10334 is not running.
Writing this question I've finally found How to connect a remote-locator in Geode and also can't PING the GFSH server from the SPRING app. However, the server bind address is setup properly for remote locator clients and various other services and UI using a locally built Geode Native Client for Geode v 1.10 can connect. I suspect PING may be disabled across this (semi-internal) network by default. I also disabled the firewall rules for ports 10334, 1099, 40404 to allow all traffic but still get the same error condition.
It turns out that from repeated INFO messages in the Spring Boot app after the connection refused:
[Timer-DEFAULT-2] o.a.g.c.c.i.AutoConnectionSourceImpl : updateLocatorInLocatorList changing locator list: loc form: LocatorAddress [socketInetAddress=UAT:10334, hostname=UAT, isIpString=false] ,loc to: UAT:10334
[Timer-DEFAULT-2] o.a.g.c.c.i.AutoConnectionSourceImpl : updateLocatorInLocatorList locator list from:[UAT:10334, /1.2.3.4:10334] to: [LocatorAddress [socketInetAddress=UAT:10334, hostname=UAT, isIpString=false], LocatorAddress [socketInetAddress=/1.2.3.4:10334, hostname=1.2.3.4, isIpString=true]]
and then running list clients on the server, the connection from the Spring Boot app to the Geode server v 1.10 is in fact established. Arrrgh!
It means the locator logic is working but this doesn't explain why after the first connection there's a java.net.ConnectException: Connection refused: connect error. Any ideas?
1 quick note about your Spring Boot application class...
#SpringBootApplication
#ClientCacheApplication(name = "CmWeb", locators = #Locator, subscriptionEnabled = true)
#EnableGemfireRepositories(basePackageClasses= {CmRequest.class})
#EnablePdx
public class CmWeb {
public static void main(String[] args) {
SpringApplication.run(CmWeb.class, args);
}
}
The following statements are true iff you are using Spring Boot for Apache Geode (or Pivotal GemFire), which is highly recommended.
When using SBDG (by declaring the correct org.springframework.geode:spring-geode-starter dependency on your application classpath), then you do not need to explicitly declare the #ClientCacheApplication, #EnableGemfireRepositories or the #EnablePdx annotations since SBDG auto-configures a ClientCache instance by default, auto-configures SD Repositories particularly when all entity classes are in the same package or sub-package as the Spring Boot app and SBDG auto-configures PDX by default, as well.
The locator = #Locator just specifies that the "DEFAULT" GemFire/Geode Pool when configured via the ClientCacheFactory should connect to the cluster via Locators, on localhost using the default Locator port, 10334. Therefore, this attribute is mostly useless and I would recommend the new #EnableClusterAware annotation from SBDG (see here).
The other attributes can be configured via Spring Boot application.properties, like so:
spring.application.name=CmWeb
spring.data.gemfire.pool.subscription-enabled=true
TIP: You can configure subscription on individually "named" Pools, even via properties, if you are using more than 1 Pool (of connections) in your application, perhaps to route different payloads based on workflows to different "grouped" servers in your cluster, etc.
You started to configure the "DEFAULT" Pool in application.properties already with...
# Configure the client's connection Pool to the servers in the cluster
spring.data.gemfire.pool.locators=1.2.3.4[10334]
Regarding...
After a lot of investigation I thought it was that the spring data geode client expects a spring boot geode server
No, SDG does not expect the cluster (of servers) to be configured or bootstrapped with Spring at all. Using Gfsh is perfectly valid. For instance. If the ListRegionsOnServerFunction is not available, SDG falls back to other means (provided by GemFire/Geode itself, which Gfsh knows and uses).
All the messages you are seeing in the Spring Boot app logs are coming from Geode itself, i.e. nothing to do with Spring. In a nutshell, and FWIW, SDG/SBDG is a facade around the Apache Geode (Pivotal GemFire) API and Java client driver. SDG/SBDG is at the mercy of this client doing the right thing, which of course, is partially dependent on proper configuration. Still... I am really just thinking out loud now since I suspect you are already well aware of (or have discovered) all of this.
I would also say the Java client and Native Client are not exactly an apple to apple comparison either. Meaning, if you developed a client using purely the Apache Geode (Pivotal GemFire) API without Spring, you'd have the exact same problem.
I have never seen a case where the first connection is establish but subsequent connections get a "Connection refused", o.O #argh
Have you tried this same configuration/arrangement with older Geode versions, e.g. 1.9?
Sorry for your troubles. I will think on this more.
I am trying to configure jms setup between two servers. The sender is on (server A)jboss 5 and the receiver is on (server B)jboss 4(which is using remote queue from server A.
When i try to run both on jboss 5 or jboss 4, it works. But when the receiver is on jboss 4 and sender is on jboss 5, then it throws below Exception.

I found below link which seems similar to the issue that i am facing but not able to get exactly on from which server to which server i need to have client libraries under war file?.
https://access.redhat.com/solutions/45133
More Details:-
In my Case, jboss 4.0.4 and jboss 5.1.0 both are hosting the messages for different queues.
-- jboss 5 is hosting the message and listener is on jboss4 for QueueA.
-- jboss 4 is hosting the message and listener is on jboss 5 for QueueB.
What we want to achieve:- Jboss 4 on server A should communicate with RemoteQueues which are configured on jboss 5 on server B, which is not working and throwing above Exception. Communication is not happening between both servers.
The bottom line here is that JBoss 4.x uses JBossMQ as the JMS implementation and JBoss 5.x uses JBoss Messaging as the JMS implementation. The two are not directly compatible therefore you need to decide which server will host the messages.
If you want the JBoss 5 server to host the messages then all the clients (including those running on JBoss 4) will need to use JBoss Messaging client libraries.
If you want the JBoss 4 server to host the messages then all the clients (including those running on JBoss 5) will need to use JBossMQ client libraries.
If you're hosting messages on both JBoss 4 & JBoss 5 servers then the clients for each will need to use the corresponding client libraries for whichever broker their working with.
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: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
I am trying to deploy a JSF portlet into a Liferay portal 6.2 running on top of a JBoss EAP 6.4, with OpenJDK 8. The portlet is deployed as a WAR file, but invokes some methods of an EJB through a remote interface. The EJB is deployed as an EAR file directly on JBoss.
On my developing machine it is working fine. But in a test machine it is not. There are exactly the same WAR and EAR files, the standalone.xml setup is almost the same for both machines, and also the JBoss modules are the same.
The stacktrace printed in the log is the following:

I rised the log level to "org.jboss.ejb.client" and now I see two interesting messages just before the stactrace:
22:13:16,684 DEBUG [org.jboss.ejb.client.EJBClientContext] (ajp-/0.0.0.0:8009-5) org.jboss.as.ejb3.remote.LocalEJBReceiverPreferringDeploymentNodeSelector#4bc9113e deployment node selector selected node for appname=SS-ADMINIS-ear-1.0,modulename=SS-ADMINIS-MAVEN-EJB-1.0,distinctname=
22:13:16,687 DEBUG [org.jboss.ejb.client.EJBClientContext] (ajp-/0.0.0.0:8009-5) Selected node doesn't belong to eligible receivers. Continuing with a random eligible receiver
Note that there is no node name in both messages (two blanks before "node").
In my developing machine, where it works, the first message does include a node name, and the second message does not appear:
18:56:37,902 DEBUG [org.jboss.ejb.client.EJBClientContext] (http-/0.0.0.0:8080-2) org.jboss.as.ejb3.remote.LocalEJBReceiverPreferringDeploymentNodeSelector#6db73304 deployment node selector selected spio node for appname=SS-ADMINIS-ear-1.0,modulename=SS-ADMINIS-MAVEN-EJB-1.0,distinctname=
The only diference is that in my machine I am going directly with the browser to the server ([Browser] -- HTTP --> [JBoss]) while in the testing machine I go through a load balancer ([Browser] -- HTTP --> [Apache] -- AJP --> [JBoss]). That is reflected in the messages (ajp-/0.0.0.0 vs http-/0.0.0.0).
The exception is thrown when I try to invoke a method from the EJB through the remote interface. The reference to the local stub is gotten by means of a lookup, and the result is not null. There are no errors at deploy and the lookup does not throw an error neither.
What can be happening or what am I missing?
A friend of mine found the solution.
Something a did't say is that the testing machine was in fact a docker container. And it seems that there is a bug in JBoss with docker making the former to not read the hostname to pick a node name, so de node name when it starts is empty. So the message above a empty name node being selected is shown, and then the error.
The workaround is to specify a node name with the -Djboss.node.name parameter to JBoss. I put that setting in the standalone.conf, restarted the JBoss and it worked fine. Now, the first message shows the name I specified, and the second message does not appear, nor the exception.
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'.
