[Beginners Corner] - Session/Entity Beans deployment
by susanthadesilva
I am trying to develop a simple EJB application to print "HelloWorld". The print method, hello() is in Entity Bean class.Session Bean is talking to the Entity Bean I am using JUnit test case to look up Session Bean.
All the Interfaces and Bean classes are in the directory EntityLab\src\lab\entity\ejb and Deployment Discripters are in EntityLab\src\config\META-INF. I am using Ant build script to build and bundle this project.
When I try to deploy this I get the Error:
Verification of Enterprise Beans failed
Enterprise Beans are partially deployed
org.jboss.deploymentInfo@ce3b86eb
org.jboss.ejb.EJBDeployer@123a389
Can anyone help me to fix this bug. My .XML files are as follows:

[EJB 3.0] - Re: ClassCastException: $Proxy94 cannot be cast ...
by ttrepper
Hi jaikiran, hi ALRubinger,
thank you for your replies and your hints. I have the same anticipation, that in my application is something wrong with the classes (and class-loaders).
My question now is how an ear-file is best packed and with which structure?
I am developing in eclipse and I have a "main"-project, which is an ear-project. Then I have a components and a util-project with classes needed by the ejbs and the web. furthermore I have a web-project and an ejb-project. The structure looks similar like this:
test (ear)
+ testEJB (holds EJBs)
+ testWeb (holds JSPs)
+ testUtil (holds Helper-Classes and Utils) (needed by web and ejb)
+ testComponents (holds components - only needed by web)
What is the best structure to pack the libs (incl. third-party like tomahawk) into the ear? What in ear-web-inf/lib, what in web.jar-web-inf/lib, etc?
Thank you very much for the help
Thomas

[Clustering/JBoss] - Re: Only one scheduler across all nodes in the cluster
by tpawankumar
Hi,
Following is the message on my console:
| 10:50:27,533 INFO [TreeCache] viewAccepted(): MergeView::[10.88.192.129:2355|1]
| [10.88.192.129:2355, 10.88.192.141:1528], subgroups=[[10.88.192.129:2355|0] [10
| .88.192.129:2355], [10.88.192.141:1528|0] [10.88.192.141:1528]]
|
This tells that they are in cluster right?
Let me tell you how i deployed.
I have ejb jar file deployed in all/deploy folder in both the nodes.Then i pasted the following code in schedule-service.xml which is inside all/deploy
folder.
<mbean code="org.jboss.varia.scheduler.ScheduleManager"
| name="jboss:service=ScheduleManager">
| <attribute name="StartAtStartup">true</attribute>
| <attribute name="FixedRate">true</attribute>
| </mbean>
|
| <mbean code="com.covad.scheduler.HearBeatScheduler"
| name="com.covad:service=HearBeatScheduler">
| </mbean>
|
|
| <mbean code="org.jboss.varia.scheduler.SingleScheduleProvider"
| name="jboss:service=SingleScheduleProvider">
| <depends>jboss.ha:service=HASingletonDeployer,type=Barrier</depends>
| <depends optional-attribute-name="ScheduleManagerName">jboss:service=ScheduleManager</depends>
| <depends optional-attribute-name="TargetName">com.covad:service=HearBeatScheduler</depends>
| <attribute name="TargetMethod">perform()</attribute>
| <attribute name="DateFormat"></attribute>
| <attribute name="StartDate">NOW</attribute>
| <attribute name="Period">10000</attribute>
| <attribute name="Repetitions">-1</attribute>
| </mbean>
.Did i deploy in the correct way or should i deploy in all/deploy-hasingleton folder?
Please help me.
Thanks,
Pavan.
