Jul 5, 2014
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

<h1>test gp senterprise project web module through parent ear</h1>

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.

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.
Check the archive to ensure correct packaging for D:DocumentsNetBeansProjectsTestdistgfdeployTestTest-war_war.
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 :

Say I have a EAR file. Inside, it has a EJB jar, web war and app client jar file. The (enterprise) app client here is a desktop GUI calling the EJBs accordingly. Now if this EAR is deployed to some app server like JBoss or Glassfish, to access the app client, users will basically use java web start/ JNLP to run the client.
Given this is the case, I'm wondering if the effect is the same as separating the app client (not part of the EAR), have that EJB jar in its library path, and deploy the GUI app as a jar. Hence users not use web start. The only disadvantage I can think for separating the app client is if the EJBs get changed, the client's version will be outdated. But other than that, are there any justification for using an enterprise app client?

I am trying to mavenize an existing enterprise application and this application has EJB, MDB and MQs. As far as the folder structure is concerned, it has a project that creates an ear file, and has one for project for web and another project for EJBs. there is one more project that holds some property file.
I am trying to mavenize this this application, so that I am able to create an ear of application containing the war of web project, jars of property project and ejb project and I am badly stuck.

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?

IDE: Netbeans 8.0.
Server ejb:
"@Stateless
public class ejb implements ejbRemote{
public String say(){
return "hello";
[Code] ....
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'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.

My project builds a war. In the war there is a jar A which provides the implementation I1 of interface I. I1 is injected in a JSF controller. There is an optional jar B which provides another implementation I2 of interface I. I2 has an higher priority than I1. Is there a possibilty to achieve when jar B is present in the war I2 is injected. I tried it with @Alternative on I2 with an entry in beans.xml as alternative in jar B without success. I1 is injected. Something like a priority would be necessary. Or probably I am on a wrong way and there's another one that fits for my use case?

I currently use Eclipse to maintain our Java application. I recently upgraded from Java 6 to Java 7. I updated my Eclipse projects to use the Java 7 .jar files. I can run the application from Eclipse via the Run Configuration.
I can also run the Ant build and it completes successfully. When I install the application on my desktop, I receive the "Java Virtual Machine Launcher: Could not find main class..." error. My CLASSPATH is set to ".".

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.

I'm deploying an EAR file on weblogic 10.3.4. The EAR file contains a war file and a jar file that implements web services using EJBs.
The application deploys and is functioning correctly. The application is available from the following URLs:
web application: [URL] ....
web services: [URL] ....
However, I would like configure the deployment to insert the "app1" string into the URL so the application is available like this:
web application: [URL] ....
web services: [URL] ....
I've been looking at some of the configuration options in deployment plans, but can't seem to get anything working.
