Deploying Entity Bean

I am trying to deploy Entity Bean(Bean-Managed Persistence) using deploytool. But in halfway of deployment, I am getting an error.
Error Says "There was deployment error.java.rmi.ServerException:Remote Exception occured in server thread;nested exception is java.rmi.RemoteException:error while loading ejb.jar"
I am not getting why this error occurs.

I am using J2EE deploytool. We are not able to trap the exact cause of error. We have created a fresh bean without any problem yesterday.

Error While deploying Entity Bean

Hi,
We are using JDeveloper 3.2.2 to deploy EJB into Oracle 9ias (Oracle 8.1.7 database). The following error occured while deploying entity bean.
"Persistence provider declared in the deployment descriptor is not supported
*** Errors occurred while deploying the EJB to 8i JVM ***
*** Deployment completed ***"
Please help us with the solution if anyone have come across this kind of error.
Regards

Thank you Raghu, We were in a position to deploy the entity bean to the database. We solved the problem by adding the following parameters to the init.ora file
(a) Java_max_sessionspace_size
(b) java_soft_sessionspace_limit
When I tried to create an EJB for a table in another schema, it started deploying the BC4J to that schama also. Is it necessary that BC4J should deploy in all the schemas of the database ? Can I deploy BC4J to one schema and grant required permissions to others users or create public synonym for BC4J ? Can you please tell me how I can deploy BC4J globally for an instance of Oracle (Applicable to all the schemas in that instance) ?

What am I missing? Note that on 9.0.4.2 and its previous versions the deployment was successful.

We use EJB2.0 and as per the specifications entity class and getters/setters should be abstract. This is what we have. I have verified the dtd used in ejb-jars and it has references to the correct version. Here is an example <!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">. Also the tag <cmp-version>2.x</cmp-version> is included for all the entity beans.
Now I am just curious to know if anyone has tried deploying Entity Beans 2.0 on a 10.1.3? and if so was the deployment successful?

Hi,
The error was coming because of the table structure. All the columns were composite keys. I alter the structured by removing composite keys and added a new column as primary key. Now it is getting deployed successfully.
Can anybody comment on such a behaviour of OC4J?

I changed schema locations of descriptor files as suggested at http://download.oracle.com/docs/cd/E17904_01/web.1111/e13706/overview.htm#i1074199 (see the third category for '*Enterprise Bean 2.1*' in the listing Table 1-1). Alternatively, you may see the schema locations for EJB2.0 directly at http://download.oracle.com/docs/cd/E17904_01/web.1111/e13719/dd_reference.htm#EJBPG481

JRE version in JBoss is 1.6.0_16. JVM in web logic is pointing to jrockit_160_22_D1.1.1-3 which is come in the package. It doesn't seem to be related to JVM version mismatch.
I think it is an issue with definitions in weblogic-cmp-rdbms-jar.xml file. How should be the definition of entity-descriptor appear for entity bean which has finder methods in ejb-jar.xml?
Please see the snippets from corresponding descriptor files below.

Difficulty deploying Entity Bean in Web.ser.5.1

I am trying to deploy the Container managed Entity beans in Weblogic
App.Server5.1.But while using the command "java weblogic.ejbc source.jar
target.jar" I get the following error
ERROR: Error from ejbc: [9.2.8] In EJB Beans, the home interface must

ERROR: ejbc found errors.
I am not familiar with the
xml deployment descriptor.I used the xml files from the weblogic
examples and modified it to fit my example.
Can anyone help me out.

From what the message says, your EJB has to define a findByPrimaryKey
method. It does not. You should make sure that it does.
Thanks,

Hi,
This seems to be the Hello world EJB application with a small
modification(probably an addition of test directory or a java file). I would
recomend you to go through every line of the document on deploying this
application. There is another posting regarding the same issue in this forum.

Problems deploying entity beans with local interfaces on Jboss?

I'm trying to deploy a simple entity bean using local interfaces on Jboss 3.2.1 and I obtain the following exception:
19:08:51,875 WARN [verifier] EJB spec violation:
Bean : UsersEJB
Section: 9.2.2
Warning: The entity bean class must not be defined as abstract.
19:08:51,875 WARN [verifier] EJB spec violation:

Section: 9.4.7.1
Warning: The primkey-field element must name a public field in the bean implemen

Any idea?

I guess you are missing <cmp-version>2.x</cmp-version> for your first warning and <primkey-field>primary key field </primkey-field> for you second warning in your ejb-jar.xml

Deploying entity beans with Local interfaces on Jboss

Hi, I'm trying to deploying a simple entity bean on Jboss. The EJB has been developed with Local Interfaces because then I want to access it with a session bean facade.
I get the following error:

23:41:25,984 WARN [verifier] EJB spec violation:
Bean : UsersEJB
Section: 9.2.2
Warning: The entity bean class must not be defined as abstract.
23:41:25,984 WARN [verifier] EJB spec violation:
Bean : UsersEJB
Section: 9.4.7.1
Warning: The primkey-field element must name a public field in the bean implemen
tation class.

I'm following what is wrote in the Professional EJB editeb by wrox?
Is it possible to deploy an entity bean alone with Local interfaces? Is there something I'm missing? It's true that I defined the implementation class as abstract, but because there are abstract getter/setter methods.
Thanks for any help,
Marco

Is it possible to deploy an entity bean alone with
Local interfaces? Is there something I'm missing? It'sYes it is (no, you are not "missing something" ;). In fact, this is recommended practice in most cases under CMP 2.0 - CMR having been a major impetus to the development of Local interfaces in the specification. ;)
true that I defined the implementation class as
abstract, but because there are abstract getter/setter
methods.No problems. You are "right on track" for CMP 2.0. :)

This is adapted from the Savings Account example. I couldn't get it to work either
from the source provided though it did work with the provided ear. I have been
comparing the difference in setting but can see anything.
I have been able to build and deploy all the other examples in the tutorial but I am somehow
stuck on ejbs.
Help would be much appreciated.
cheers,
paul

Just had a look at the client jar. The one generated by the Savings Account provided ear has got a shorter ejb-jar.xml. It doesn't have the functions specified like the one in its ear file.
Another difference thet the Manifest.mf files for my client jar do not have as many paths specified
as my test client jar. Don't know why. I am suspecting that maybe there is a slight configuration problem in my j2ee setup. Though I am not sure waht or what to look for. I hope this little bit of
extra info helps.
cheers,
paul.

Urgent: Can't lookup entity bean

Dear all,
I define a business process in workflow engine, which invoke a java class to get
DB data through CMP entity bean. The entity bean was packed in to a ear and was
workable/callable within the same ear.
However, when the workflow engine can't invoke the entity bean, the workflow engine
always throw exception as following.
javax.naming.LinkException: . Root exception is javax.naming.NameNotFoundException:
Unable to resolve 'app/ejb/ConsignmentEntityBean.jar#Consignments/local-home'
Resolved: 'app/ejb' Unresolved:'ConsignmentEntityBean.jar#Consignments' ; remaining
name 'ConsignmentEntityBean.jar#Consignments/local-home'
I think the problem may occur in deployment/configuration. Since the problem is
very urgent, anyone can help me? To all developers, How do you package/deploy
Entity Bean in Integration Server?
Thx,
Philip

I solved this.
Since I was testing the action code only, I didn't define a navigation entry corresponding to the action string returned for this button:
<h:commandButton value="Add" style="height:21px; width:51px;font-size:8pt; font-color: black;" action="#{resourceBean.addAction}">
</h:commandButton>After I added a nav definition, it worked. I don't know why at this point. I suspect a key step in the lifecycle was pre-empted...someone else can probably explain why. If I get a chance to research it after I'm done with my project, I'll update this post.
Thanks.

Strange behavior with entity beans and servlets in a cluster

We have 2 WebLogic 4.5.1 servers in a cluster with none of the Service
          Packs installed. When a client uses the deployed entity beans or
          servlets they work every other time. The times they do not work nothing
          happens. No exceptions, no responses to the client ( i.e. HTTP 404s ),
          nothing. I suspect something in the cluster setup since we do not have
          these same problems on non-clustered entity beans or servlets. We have
          made sure all the entity beans have the Shared Database flag set on and
          added the delayUpdatesUntilEndOfTx false to the enviroment of the DD.
          That didn't fix the problem. Any ideas?
          Thanks in advance,

Do you have log files?
