When I'm running my program, I get the following error:
... nested exception is
javax.naming.NameNotFoundException:
ejb not bound
The error occurs at the start up when Java wants to create a certain bean.
The Bean is a SimpleRemoteStatelessSessionProxyFactoryBean. Could it be that I ain't got the rights to access the naming provider URL although I can ping it?
When accessing the bean on my local JBoss there are no problems.
Ok, the bean wasn't running on the remote service. No wonder it didn't work.
It found out through the jmx-console's JNDIView -> list() function.

com.ibm.ws.naming.util.InvalidObjectException: Some object reference in the name "MyEJB" relative to the context "path/to/myserver" is invalid.
Some possible causes include a context binding in the name which refers to a destroyed context, or an object binding which contains an invalid EJBHome reference.

The lookup of other ejbs in the app is working. The difference is the bean class of this ejb was modified and only the new class file was updated in the ear and the app was updated with this ear file in WAS admin console.
Do I have to regenerate the deployment code(stub/tie etc) for the ejb?
The EJB deployment code only needs to be regenerated if the bean interfaces have been modified or the signature of the bean implementation methods has changed. If those have not changed, then likely the issue is the bean failed to start. Check the logs (Systemout.log and FFDC logs) for any other errors related to that EJB. The application may have started fine, but typically EJB initialization is deferred until first use, which is often the first time the bean is looked up. Finally, verify the logs contain a CNTR0167I message indicating the bean was bound in JNDI using the lookup name.
I have been working with Spring for 8 years now, and very often I run into this exception.
BeanCreationException: Error creating bean with name
For example, I am working on a service right now that fails to start because a Bean requires a connection to Azure (on AMQP port) to be successful. The stack trace says nothing about the cause of the error though. Enabling com.azure.core or org.apache.http logging DEBUG also not helping.
Is it possible to intercept the Bean instantiation to reveal more information about the cause of the error? Is there a Spring coding pattern for this kind of thing?
Would love to solve this once and for all so that users of services I create are never confused about a Bean loading exception.
This page elaborates on the issue: https://www.baeldung.com/spring-beancreationexception but never tells you what to do when dealing with Beans being loaded from a 3rd party lib rather than your own code.
I trying inject a EJB into my class using a InitialContext (JNDI). For this i use a Netbeans insert code mechanism:
after that Netbeans know witch injection have to use. #EJB annotation or JNDI Lookup. In my Example i have a simple, not managed class and what i want to do is inject a EJB Bean using JNDI. So Netbeans generate code for me as bellow:
problem is that. When Netbeans generate code for me. He change a web.xml file and add there ejb-local-ref node:
and when i trying a turn on my web application. I run glasfish and i always get following error:
Exception while deploying the app [mavenproject1-ear] : Error: Unresolved <ejb-link>: mavenproject1-ejb-1.0-SNAPSHOT#LanguagesFacade
i really dont know what to do. Can someone help with this issue. I will greatful for help.
Just remove the <ejb-local-ref> all together. It's defined for dependency injection and this is not your case here since you use JNDI to lookup the bean and set it in langaugeFacade variable. Just remove it and things will be fine.
I just want to call a Ruleset with Local EJB3 Session.
I get the exception javax.naming.NameNotFoundException: Name "ilog.rules.res.session.impl.ejb3.IlrStatelessSessionLocal" not found in context "ejblocal:" in websphere. What are the possibilities that this can happen?
source codes:
// get a rulesession --- 001
IlrEJB3SessionFactory sessionFactory = new IlrEJB3SessionFactory();
sessionFactory.setStatelessLocalJndiName("ejblocal:ilog.rules.res.session.impl.ejb3.IlrStatelessSessionLocal");
sessionFactory.setRemote(false);

It appears that there is no such EJB bound to that location. I believe the "ejblocal" namespace is specific to WebSphere Application Server, so you should be able to find the actual location of the EJBs by looking for CNTR0167I messages in the SystemOut.log. Alternatively, you might find that the application containing the relevant EJB did not start properly.
in the application xml, click on project tab then click on a downer label such as "jar utility management", then you must add, checking the box, the bean involved in the error.
I am getting this exception when I am trying to read message from WebSphere MQ via MDB, can any one please guide me.When I deploy the EAR file on my WebSphere then it works flawlessly but I am getting exception on a different WebSphere. Am I missing something in configuration, why does this exception occur?
javax.ejb.EJBException: Injection failure; nested exception is: java.lang.IllegalArgumentException: Can not set javax.jms.ConnectionFactory field com.ultramatics.hawkeye.mdb.listener.HawkeyeMdbListener.replyCF to com.ibm.mq.jms.MQQueue
You are obviously trying to assign a ConnectionFactory field with a MQQueue object, two different types.
I guess you grab them from JNDI or similar and that there might be some naming mess up in the configuration?
