I am following this tutorial: https://netbeans.org/kb/docs/javaee/ecommerce/entity-session.html
I can add the entity classes but when I move on to the next step of adding session beans, NetBeans won't allow it and gives me this error:
Cannot be generated because EJB Lite classes are not available on project classpath
How do I fix this issue?

I asked this questions already here:
https://www.eclipse.org/forums/index.php/t/1098133/
Now, after 3 weeks, i hope to have luck to reach a response here in stackoverflow.
I have a RCP applcation using MOXy to parse complex XML, the annotated classes are generated by XJC, and the package contains a ObjectFactory and a jaxb.properties pointing to MOXy.
The problem: The application works with Java8, but starting the application with Java11, i get this exception:
java.lang.RuntimeException: javax.xml.bind.JAXBException
- with linked exception:
[Exception [EclipseLink-50000] (Eclipse Persistence Services - 2.7.4.v20190115-ad5b7c6b2a): org.eclipse.persistence.exceptions.JAXBException
Exception Description: The context path mypackage contains no ObjectFactory or jaxb.index, no external metadata was found in properties Map, and sessions.xml was found or was invalid.
Internal Exception: Exception [EclipseLink-7095] (Eclipse Persistence Services - 2.7.4.v20190115-ad5b7c6b2a): org.eclipse.persistence.exceptions.ValidationException
Exception Description: The sessions.xml resource [sessions.xml] was not found on the resource path. Check that the resource name/path and classloader passed to the SessionManager.getSession are correct. The sessions.xml should be included in the root of the application's deployed jar, if the sessions.xml is deployed in a sub-directory in the application's jar ensure that the correct resource path using "/" not "\" is used.]
My target platform contains:
org.eclipse.persistence.moxy_2.7.4....jar
jaxb-osgi-2.3.2.jar
jakarta.activation.jar
jakarta.xml.bind-api.jar
I use Multi-Release: true to be able to handle Java8 vs. Java9+.
In the main MANIFEST.FM i require org.eclipse.persistence.moxy.
In the versions/9/OSGI-INF/MANIFEST.FM I add the import packages: com.sun.xml.bind.v2, javax.xml.bind
To start the application in the Eclipse run configuration dialog, i switch the JRE Java8 vs Java11, and in the plugins tab, i remove (J8) or add (J11) com.sun.xml.bind.jaxb-osgi (jaxb-osgi.jar) to make it startable.
Can someone help?

HAdoop single node cluster is working fine. HAdoop is working fine. JPS/Web interface of hadoop working fine.
I have done set up of hive.
When am entering into hive from hadoop its giving me below error :
"Exception in thread "main" java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory
Can someone help me in this case
If you get the slf4j IllegalAccessError shown above, then you are using an older version of slf4j-api, e.g. 1.4.3, with a new version of a slf4j binding, e.g. 1.5.6. As mentioned in the slf4j faq on IllegalAccessError, this typically occurs when your Maven pom.ml file incorporates hibernate 3.3.0 which declares a dependency on slf4j-api version 1.4.2. If your pom.xml declares a dependency on an slf4j binding, say slf4j-log4j12 version 1.5.6, then you will get illegal access errors.
Also refer to the solution here: IllegalAccessError slf4j
I am using WebLogic 11g. I am using Eclipse. I have created a EJB project. This project is called 'remote-ejb'.
The bean class HelloWorldBean implements a remote interface HelloWorldBeanRemote with just on method; public String getName();
I then deployed this project as an application successfully.
I then created a second EJB project called cart-ejb. This project uses the bean from the first project. When I deploy this
project I get the following error:
Module named 'cart-ejb' failed to deploy. See Error Log view for more detail.
weblogic.application.ModuleException: java.lang.ClassNotFoundException: beans.HelloWorldBeanRemote
Exception received from deployment driver. See Error Log view for more detail.
How can I fix this error?
I created a Fusion Webapplication project with Oracle jdeveloper 11g (11.1.5 but the same problem occours with the 11.2.1 version). Then I created a jsf page and I deployed the project to an external weblogic server (WL 10.3) with the ADF runtime support and evrithing where working.
Then I created the POJOs object (to the model project, because I have 2 proj: Model and ViewController for the web pages and backing beans) from the DB tables and a session bean who provides queries methods. After that (and so far everything it's ok) I added an ADF Data Control bound to the session bean and then I bound (via editor) one of these methods into the jsf page using an ADF table.
If I run the project using the run button everything work, but if I deploy it into both the external deployment WL server and in the internal one I get the following error
[05:30:04 PM] [Deployer:149193]Operation 'deploy' on application 'Prova_application1' has failed on 'AdminServer'

[05:30:04 PM] weblogic.application.ModuleException: Could not setup environment
[05:30:04 PM] #### Deployment incomplete. ####
[05:30:04 PM] Remote deployment failed
but there is such refernce into the web.xml and I bound the Model project into the deployment descriptor. I red every post in the web but I still can't face the problem.
The web.xml in the ViewController project contains the EJB reference (automatically created from jdeveloper) and I bound everithing the Model project but it still doesn't work.
In JDeveloper IDE
you need to set ejb-jar.xml path.
- Right click on your project
- Choose Project Properties
- Go to EJB Module
- Set EJB Version (For example: "2.1")
- Set ejb-jar.xml path (For example: "..\src\META-INF\ejb-jar.xml")
I hope it works..
I'm trying to unit testing a EJB with entity crud operations. I already was capable of testing it just running my web application (and all works), but I want to do it with JUnit.
So, my environment is Netbeans 7, Glassfish 3.1 (JavaDB, EclipseLink), JUnit4.
When I create a test class for my EJB, the code template uses the following line of code that throw an exception when I run the code:
EJBContainer container = javax.ejb.embeddable.EJBContainer.createEJBContainer();
the exception is:
java.lang.RuntimeException: Invalid resource : jdbc/mine__pm
Exception while preparing the app : Invalid resource : jdbc/mine__pm
My EJB has an injected EntityManager that points to my persistence unit. This persistence unit is referencing a data source that I JNDI named jdbc/mine created by Netbeans for my Glassfish. It runs and I can see it on my server. I tried using a glassfish-resource.xml to do the same thing too.
Why doesn't it work?
