weblogic equivalent initialContextFactory in JBOSS? - jboss

In web logic ther is intialconextfactory value in web logic is "weblogic.jndi.WLInitialContextFactory" what is in JBOSS 7,1.1 final

You will want the following jndi property:
java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory

Wildfly10 (EAP 7) call jboss 5.0.1 EJB without legacy jars

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?

How to inject/lookup EJB from SevletContextListener in JBoss AS 6

I am facing stackoverflow error when I inject ejb using #EJB or JNDI lookup using InitialContext. Can anybody share kow to inject/lookup EJB from SevletContextListener in JBoss AS 6.
Thanks!
For lookup, you can do something similar to this
InitialContext ctx =new InitialContext();
EjbServiceInterface service= (EjbServiceInterface) ctx.lookup("java:global/earName/ejbJarName/EjbServiceInterfaceImpl!com.example.EjbServiceInterface");
In this example, EjbServiceInterface is a remote interface for EjbServiceInterfaceImpl, which implements the ejb service.
The jndi string depends on the place where you are doing the lookup.. For a local lookup, you don't have to specify earName and ejbJarName.. I recommend looking in your startup log, where it shows the jndi names available for your ejb, and then select the one you need.

JBoss 7.1: java.lang.IllegalStateException: No 'jboss' MBeanServer found

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'.

InitialContext.lookup() parameter in JBoss 7.1

I am new in the world of EJB 3.1 and trying to get some basics with the JBoss Application Server 7.1.
At the moment I am stuck at a - really basic - problem. When a bean on the server wants to use another bean I need to use the InitialContext.lookup() method. If I look in the literature I found calls like:
TheBean = (<Interface>) new InitialContext().lookup("<NameOfTheBean>/local");
But this call doesn’t work for me. Every time I get an error like this:
javax.ejb.EJBException: javax.naming.NameNotFoundException
After hours of looking for a solution I found code examples which use another call, something like this:
TheBean = (<Interface>) new InitialContext().lookup("ejb:/<Package>//<NameOfTheBean>!<Package>.<Interface>");
Well this solution works for me but the question is why? Does somebody know why the first call produces exceptions while the second one works fine?
Thanks a lot!
Why? Different versions of JBoss deploys beans with differently default names in JNDI namespace.
ctx.lookup("BeanName/local")
was right for the JBoss 4.x.x and higher but not for JBoss v7.
You can see in you server.log of JB7 how your beans mapped to JNDI names,
for example (see java:/jboss/exported/... and how it correspond to your second successive call):
13:57:05,550 INFO [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-4) JNDI bindings for session bean named ProductionHistoryBean in deployment unit deployment "navi-ejb3.jar" are as follows:

JBoss6 AS EJB3StandaloneBootstrap & EJB3StandaloneDeployer

currently i'am migrating a JBoss 4 project to JBoss 6. I do miss substitutes for the EJB3StandaloneDeployer and EJB3StandaloneBootstrap.
Are there any new sources which deliver the functionality of this two classes?
THX
My guess is that EJB3StandaloneDeployer and EJB3StandaloneBootstrap are replaced by the standard EJBContainer API. Here is an example:
// Instantiate an embeddable EJB container and search the
// JVM class path for eligible EJB modules or directories
EJBContainer ejbC = EJBContainer.createEJBContainer();
// Get a naming context for session bean lookups
Context ctx = ejbC.getNamingContext();
// Retrieve a reference to the AccountBean using a
// portable global JNDI name (more on this later!)
AccountBean ab = (AccountBean)
ctx.lookup("java:global/account/AccountBean");
// Test the account
Account a1 = ab.createAccount(1234);
...
// Shutdown the embeddable container
ejbC.close();
JBoss also started the Arquillian that you might find interesting.
