Enterprise JavaBeans :: Unable To Load Module - DeploymentContext Does Not Contain Any EJB
Apr 1, 2013
I'm writing an enterprise application to familiarize myself with Glassfish 3.1.2 and EJB 3.1. I've created several local, stateless beans, and injected one into a JSF managed bean. The ejb and web modules compile fine, but when I launch the application with Glassfish I get the following startup error and the application does not deploy.
SEVERE: Exception while invoking class org.glassfish.ejb.startup.EjbDeployer prepare method
SEVERE: Exception while invoking class org.glassfish.javaee.full.deployment.EarDeployer prepare method
SEVERE: Exception while preparing the app
SEVERE: Unable to load the EJB module. DeploymentContext does not contain any EJB.
org.glassfish.deployment.common.DeploymentException: Unable to load the EJB module. DeploymentContext does not contain any EJB.

If you use EJB component annotations to define the EJB, and an ejb or web deployment descriptor is also used, please make sure that the deployment descriptor references a Java EE 5 or higher version schema, and that the metadata-complete attribute is not set to true, so the component annotations can be processed as expected :

I have included the log4j.jar in libraries; added log4j.xml in the sources folder; but I am getting an error:

I have created one new enterprise aplication project called July2014. While creating I have added one new EJB module called July2014EJB for business logic and one new web module Called July2014Web for the UI(I see connector module and application client module what are the uses of them and when should i select them).I have addded one index.jsp with below sample code

I did multiple times clean, build, publish, restarting the server.I have not done refreshing EAR, EJB and web project. how Refresh is useful and different from clean and build.

When I run the Web project on the Server host, it's OK. But when I run it on another host it returns error. I can access 192.168.0.2:7676 in browser(returns some context string), so it may not be caused by firewall.
I think the problem is the initalContext is not generated from 192.168.0.2:7676 but from local JVM, because when when running it in the Server I change the ip address to random number it also is OK.
I am looking for the ability, on the server side, to run programs or "jobs" in a job queue, where the jobs are processed as first in first out. If you are familiar with the IBM iSeries, they have a built in job queue mechanism which accomplishes what I am looking for. The primary purposes for this would be to process and update large amounts of data in a thread safe environment.

How can I connect to multiple Databases (using @PersistenceContext) using an EJB? Did I need to connect various Entity Managers corresponding to the each database and simply send my Queries?
I am using Glassfish Application Server Netbeans IDE Java Derby Database Oracle Database Java Persistence API
Recently we updated out database and we changed our tables' and columns' names, I'm developing an adf application with EJB3.0 the question is that the new column names start with a number (eg. 001U_ID), its a kind of encoding the names of the tables so no one can modify the values.
When I create a query on the table it is throwing an exception:
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near 'U_ID'.
I think the problem is that the EJB3.0 doesn't recognize column names starting with a number!!! What can I do to solve this issue?
I finish reading The EntityManager Interface in JEE tutorial. I know I can use container manager entity manager in EJB, but I want to explore how to use application managed entity manager in EJB.
Can I use application managed entity manager in EJB (container management JTA transaction is used)? Where do I should close entity manager if can?
The following is an example from JEE tutorial, but didn't find where to calose entity manager. and can I create mutiple EntityManagerFactory objects and Entity Manager objects to use them in a JTA transaction?
I want to develop separate projects for web layer (.war) and for Business layer (.jar). I want to deploy these layers on different Glassfish servers.
Here is my Approach -
1. Create a separate module for remote interfaces (.jar), use @remote annotations 2. Create a Web module using JSP/Servlets (.war) and use this remote interface jar in it. 3. Create a EJB module (.jar) and implement these remote interface in it. 4. Use JNDI in Web layer to access the EJB methods.
A getting started app is fine, need to understand of deploying a sample application to WebLogic server. Any particular configuration during WLS install?
I am using EJB (Stateless) without any web service. I simply need to send a String from Client to Server
I can connect any Java SE Client with this EJB. But how I can connect an Android Client with this EJB (i.e. Using EJBRemote Interface) directly? I am using :
We have a J2EE business web application that runs in WebLogic. We noticed in application log files errors messages that seems like "No resource available in db pool", it means all the connection objects (to Oracle database) are used. Then the application is unstable and unseable.
I think the maximum number of connections configured in Weblogic pool has been reached due to an increase of users and activity. But when the workload decreases the application is still out of service. It seems connections objects are not relased to the pool. What can be the explanation for this issue ? Normally it is managed by the container (EJB3 for the business tier).
Once the limit of the pool is reached it is necessary to restart the server to solve this kind of error ?
There is a weblogic server running at remote place and i need to access the API's in that remote method using JNDI lookup. My application is configured in Spring Tool Suite IDE with java 6 and tomcat 7 and I have used Spring to perform the jndi lookup of weblogic server. In spring i have used simpleremotestatelesssessionproxyfactorybean class to lookup a weblogic server using jndi and get the remote object. But somehow on doing it i'm getting the following error.
org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 203 completed: Maybe at com.sun.corba.se.impl.logging.ORBUtilSystemException.writeErrorSend(Unknown Source) at com.sun.corba.se.impl.logging.ORBUtilSystemException.writeErrorSend(Unknown Source) at com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl.sendWithoutLock(Unknown Source) at com.sun.corba.se.impl.encoding.BufferManagerWriteStream.sendFragment(Unknown Source)
[Code] ....
The exception is been thrown at com.sun.corba.se.impl.encoding.CDROutputObject method when calling writeTo(). Why I'm getting this error and can I do anything to remediate it. Irrespective of java this error occurs, i tried with java 5, 6 and 7 but still getting the same error.
I'm trying to install java_ee_sdk-6u3-jdk7-windows-x64.exe on our new Windows Server 2012 machine but the installer starts and I then get a Setup box appear that says Error: The Java(TM) Virtual Machine has aborted. I've looked in the Event Viewer and there are no messages and I've tried to get the installer to create a log file (by passing the parameter -l <loglocation>) but it doesn't seem to get that far as no log is created.
The very first time I tried to run the JavaEE install on this machine, it installed everything ok but didn't create the windows service as .NET Framework 3.5 was missing. So I uninstalled JavaEE and added in the .NET Framework 3.5 and then my problems began. I have already installed these versions of Java and JavaEE successfully on a previous Windows Server 2012 machine which had the .NET Framework 3.5 on it.
The JRE installed already on the computer is jre-6u45-windows-x64.exe and I am logged in as an administrator. I've tried uninstalling the JRE and reinstalling and also doing a registry clean using CCleaner incase there are any old references to the JRE/JavaEE but it didn't work.
I have an stand alone client to use a remote ejb with some methods. All works fine, but when I pass an entity class as parameter from the stand alone client to the remote ejb, the entity class is received as null.
I would like to know the J2EE architectural explanation with respect to HTML5 and Adobe Flex technologies. It is just like knowing over all J2EE architectural aspects and how HTML5 and Adobe Flex technologies are used to satisfy those aspects in order act as client side components.
Now I played a little with EJB3. I want to start a timer bean in a 10second interval which retrieves the IP of registered devices from a databases, opens client sockets with a Thread Pool and retrieves the XML file over HTTP GET of each device listed in the db.
Is it possbile with EJB3? how to start thread based background services like that within EJB3 timer bean?
