Finder method in container-managed entity bean
Finder method of a container entity bean is taking the primary key class object of another entity bean. How to map this in the xml descriptor file weblogic-cmp-rdbms.xml for this type of beans.
I am trying to deploy the jasmine computer store of Mastering EJB by EdRoman.
I couldn't write the deployment file weblogic-cmp-rdbms.xml for Order Entity bean which uses CustomerPK as an argument in its finder method.
Please tell me how to write this. I am trying on weblogic 5.1
Thanx in advance

hello,
in container managed persistence, you specify on your xml file the name of your table. so the primary key you want to use have to be a foreign key in your table. otherwise i don't think that you can use a container managed persistence.

Container Managed Entity Beans and Client Identifier in Oracle
Is it possible to use Container Managed Entity Beans (EJB with CMP)
in a way that the Oracle database sessions still know the
individual Client Identifiers of the actual users
(not just the Identifier of the proxy user defined in the
Connection Pool)?
If Yes: How?
If No: The consequence would be that the
technologies EJB with CMP cannot be user together with
Oracle Virtual Private Databases (VPN) because VPN requires
some kind of Client Identifier.
I am grateful for any hint.
Regards,
Martin Siepmann
+49 (0)163 / 7765328Not quite an auto-incrementing PK, but it is managed by the container. the following is from the turorial
Generating Primary Key Values
For some entity beans, the value of a primary key has a meaning for the business entity. For example, in an entity bean that represents a phone call to a support center, the primary key might include a time stamp that indicates when the call was received. But for other beans, the key's value is arbitrary--provided that it's unique. With container-managed persistence, these key values can be generated automatically by the EJB container. To take advantage of this feature, an entity bean must meet these requirements:
* In the deployment descriptor, the primary key class is defined as a java.lang.Object. The primary key field is not specified.
* In the home interface, the argument of the findByPrimaryKey method must be a java.lang.Object.
* In the entity bean class, the return type of the ejbCreate method must be a java.lang.Object.
In these entity beans, the primary key values are in an internal field that only the EJB container can access. You cannot associate the primary key with a persistent field or any other instance variable. However, you can fetch the bean's primary key by invoking the getPrimaryKey method, and you can locate the bean by invoking its findByPrimaryKey method.
Maybe that is good enough

Setting composite key in Container Managed Entity Bean
In my database table i set primary key to two columns making them as composite key. how do i set that in my container managed entity bean home interface findByPrimaryKey() method and in deployment descriptor file.
1. create another class (say CompositePK) that will embed the two fields keyA and keyB corresponding to the two pk of your table (declare them public) .
2. in your Bean declare keyA and keyB public.
3. in the dd declare your bean primary-key-class as CompositePK and the primary-key-field as keyA and keyB.
this is the method i use (with BAS) even if the key is simple (such as Integer). -

Problem with non-container managed entity manager
i am working on a project, in which i am using entity beans.i use netbeans, glassfish as application server and toplink as persistence provider .
i created a java class that handles all the operations with the entitys, which means i using non-container managed entity manager.
in the constructor
try{
EntityManagerFactory emf = Persistence.createEntityManagerFactory("voidPU");
entityManager = emf.createEntityManager();
catch(Exception ex){
throw new EJBException(ex.getMessage());
}then i call a function in this class from a servlet
the code of the function
List users = null;
try {
ProgLanguages progLanguage = entityManager.find(ProgLanguages.class, languageId);
users = (List) progLanguage.getUserIdCollection();
catch(IllegalStateException illegalStateException){
throw new EJBException(illegalStateException.getMessage());
catch(IllegalArgumentException illegalArgumentException) {
throw new EJBException(illegalArgumentException.getMessage());
}i got an IllegalArgumentException saying Unknown entity bean class: class vanguard.server.entity.ProgLanguages, please verify that this class has been marked with the @Entity annotation
what confuses me is that sometimes it works and most of the time it does not work, have i made anything wrong?, or there is a problem with any of the tools netbeans, glassfish, or toplink?Is it always the same entity that is reported as 'unknown' ? You mention that it works sometimes but is it the same deployment and the same code that works? The first thing I would verify is that the ear is being created as expected by netbeans. Check the persistence.xml file and verify that all of the classes are listed that will be used as entities.

Bean Managed Entity Beans(EJB) using Tangosol.
I am trying to use Bean Managed Entity Beans using Tangosol Coherence.
The entity bean is currently configured in the weblogic-ejb-jar.xml with:
<max-beans-in-cache>200</max-beans-in-cache>
In the public void ejbLoad() method, I am calling the Tangosol Cache to load the entity bean.
If we have have more that 200 request coming at the same time, we get an OutOfMemoryError exception.
Is there anyway to overcome this limitation by somehow having the ejb cache to use the tangosol cache?
Thanks for any help in advance.
KrishanSo far, it's not immediately obvious to us what the exact problem is that you are seeing. It sounds like the VM would be using at least 200MB just for the application server's own internal cache, for example, and that you are also using Coherence within the application server to provide additional caching.
If possible, we should set up a phone call with you and your team, and we could get an engineer from our end to walk through your specific use case with you, so that we could understand what the exact technical challenge(s) is(are) in this particular application.
Peace.
p.s. You can email [email protected] directly to schedule a call. -
Can i user UserTransaction in a Container-managed transaction Bean
can i use UserTransaction to control transaction boundaries in a container-managed transaction bean method?
below is the method:
there is one-to-many between Employees and SalaryItem
@TransactionAttribute(value = TransactionAttributeType.REQUIRED)
private void initEmployeesSalary(Long salarySumId) {
for(Employees employees: liEmployees){
for (int i = 0; i < 20; i++) {
SalaryItem item = new SalaryDetailItem();
employees.addSalaryItem(item);
when there are about 1000 employees,the method run very slow.
What do you think I should do?
nullHi again,
The EJB specs say that a stateful Session Bean with CMT is NOT allowed to use the UserTransaction; see page 361 of the EJB2.0 specification. So combining them will not (or should not) work.
I suggest CMT+SessionSynchronization combined with using a flag to indicate whether notify should be called or not. Otherwise, you could try splitting up the bean into two beans: one with CMT and another one without. The one without CMT could use the UserTransaction and notify.
Also, you might want to check http://www.onjava.com/pub/a/onjava/2001/10/02/ejb.html
Hope that helps a bit,
Guy

Does WLS 6.1 sp2 allow (bean managed) entity beans to have transaction mode NOTSUPPORTED?
Hi,
I have created two bean managed entity beans, User and Role, abstracting users
and groups in a ldap base. A User may have more than one Role. This is represented
by a (bean managed) 1:many relationship directed from User to Role. For some weird
reasons I get a transaction rollback when reading data, when transactions are
turned on (REQUIRED).
While we where running WLS 6.1 sp1 we had no problems with this as we could set
transaction to NOTSUPPORTED for these two EJBs. Due to other hickups we had to
upgrade to sp2 and suddenly the error reappears leading me to believe that NOTSUPPORTED
isn't allowed anymore by the WLS. I know that NOTSUPPORTED isn't required by the
EJB spec, but containers may support it and obviously WLS used to do just that.
I have not seen any change in the release notes of sp2 that indicates that this
behaviour has changed.
Does anybody know if WLS really doesn't support NOTSUPPORTED for enity beans anymore
in sp2?
If anybody are curiuos or have any good ideas, the stacktrace I get is:

It looks like you've hit a bug in the EJB container where an internal Collection class has been modified while the
container is running through an iterator on it.
You should open a case with [email protected]

Calling Stateful & Statless Methods from the same Entity Bean[EJB2.0]?
Dear All,
We using EJB2.0........
Regarding segregation of stateless and stateful methods..These methods are defined in Session bean.Now my question is
Is it a good practice to call Stateful and Stateless business methods from same single entity bean("EntityBean") defined at program level by extending MainBean..
The architecture is like
public class EntityBean extends MainBean
Public Methodxyz
stfobj.MakeConn();
stlobj.getXyz();
stfobj.CloseConn();
Public Class MainBean{lookup("stl");lookup(stf) ;stl_obj=home.create;stf_obj=home.create()............}

Edited by: user9052593 on Jun 18, 2012 2:25 AMAll Business logic resides in session beans[Stateful or Stateless]..For stateful beans we are opening connections in entity bean ,calling business methods and closing connection in entity bean itself..Problem is
I am doing lookup for stateful and stateless both since both objects are called by extending MainBean in same entity bean else will give null pointer exception..
So whenever i call a Stateful or Stateless method from entity bean Which ultimately extends/calling MainBean and thereby calling home.create methods of stateful and stateless both..creating objects..Is this way fine or it will affect the performance?
Do i need to segregate the Calls/invokation to Stateful / Stateless methods at entity bean level too..
For ex:- Whenever i call Methodxyz() method ..at the same time it create 2 objects as its extending MainBean...i want to extend/create 1 object either of stateful or stateless one for stateful and stateless methods call respectively..
See the code in entity bean is like
public class EntityBean extends MainBean
Public Methodxyz
stfobj.MakeConn(); call to stateful method defined in stateful bean
stlobj.getXyz();// call to stateless method defined in stateless bean
stfobj.CloseConn(); call to stateful method defined in stateful bean

Accessing collection field in container managed persistence bean
Hello!
How can i get 1:m relatioship, collection fields value?
What is the purpose of ejbSelect-method, in bean business class?Please ask your EJB questions within the Enterprise JavaBeans section of this forum.
The ejbSelect Method is a query method (like the finder mehtod) but it is not directly exposed to the client in the home interfacce or component interface. Rather, ejbSelect() is used internally within an entity bean as a helper method to accesss a storage. ejbSelect() is useful when you have entity beans in relationships with external data, such as other entity beans.
look at http://www.theserverside.com/articles/content/ApplyingEJB/matena8.pdf for an example -
Is CMR methods necessary in CMP Entity Beans?
I refer to the J2EE 1.3.1 SDK CMP Customer application sample.
I looked thru the CMP sample source code from the J2EE 1.3.1 SDK under /j2sdkee1.3.1/doc/sample and found that for every relationship the CustomerBean has with another Bean, there has to be some CMR methods.
In this case, Customer has a:
public abstract void addAddress(LocalAddress address)
public abstract void addSubscription(LocalAddress)
For the other That I understand. It's like specifying the foreign key for the record, so to speak.
So for every foreign key field in other Beans (tables), does CustomerBean need a CMR method (get/set)? So if CustomerBean has 20 other tables using the CustomerID as a foreign key, does that imply that CustomerBean will have at least 20 CMR methods so that other Beans can add themselves and connect to CustomerBean?
Another thing I noticed is that for Beans with foreign key(s) (sorry for including database terms, perhaps just called reference now in J2EE), they all link up to the other Beans (tables) in ejbPostCreate by adding themselves to the Bean Collection.IMHO you don't have to map every relationship
(at DB level) when you declare CMR fields
at EJB level.
You have to answer at this question:
"When I load/find an Entity Bean, I need, at the same time,
to load Bean related to the Entity Bean ?".
If the answer is YES then you'll declare a CMR
field to express the relatiosnhip.

EJB 3.0 question - saving an entity bean containing another entity bean
Hi,
First, I want to store an entity bean. Secondly, I want to store another entity bean - containing the first entity bean.
I have the following code in a session bean for this:
public void saveFeedScheduling(FeedScheduling feedScheduling, FeedSource feedSource) {
FeedSource feeds = em.merge(feedSource);
em.flush();
feedScheduling.setFeedSource(feeds);
FeedScheduling feedSched = em.merge(feedScheduling);
em.flush();
This seems to work fine - still, is this the proper way to do it?Hello,
This kind of parameter can be specified using the relationship annotation.
I'm not 100% sure, but, lok at the "cascade element".

How to add a finder method in the container manager Bean in the weblogic6.1
in the environment jbuilder6 andweblogic6.1,use container manager entity Bean,it can automatic generate the findAll() method,I want to add a new method to find an element in the home interface,such as findByName(),name is a element of a table of the database.in the weblogic-cmp-rdbms-jar.xml,this is part of the fiile:
<finder>
<finder-name>findAll</finder-name>
<finder-query><![CDATA[ (= 1 1) ]]></finder-query>
</finder>
<finder>
<finder-name>findByName</finder-name>
<finder-param>java.lang.String</finder-param>
<finder-query><![CDATA[ (=name $name) ]]></finder-query>
</finder>
It can successfully compile the findAll(),but it is wrong when compile the findByName(),as follows
"www.ejbgrpx": Method Name: findByName
"www.ejbgrpx": Invalid specifications for a WebLogic RDBMS CMP EJB.
"www.ejbgrpx": ERROR: Error from ejbc: weblogic.ejb20.cmp11.rdbms.finders.IllegalExpressionException:
"www.ejbgrpx": While trying to process Finder
"www.ejbgrpx": Parameter Types: (java.lang.String)
"www.ejbgrpx": WebLogic Query: (= name $name)
"www.ejbgrpx": Finder Expressions: ()
"www.ejbgrpx": Could not parse WLQL expression: (= name $name) null
"www.ejbgrpx": ERROR: ejbc found errors
thank youThe finder methods that you are referring to are only simple finder methods. If you would like to add specialized finder methods, you can make your entity bean with bean managed persistence and not container managed. If you are using EJB 2.0, your entity bean with container managed persistence can use EJB QL for finder methods. You can search for this topic and/or download the EJB 2.0 specifications
Hope this helps -
Client Program accessing J2EE entity Bean
I have trouble find my Course J2EE bean from a client. (The client
runs on the same computer but a different VM from the bean.)
In Glassfish (Sun Application Server Nine), I set up a simple
Container-Managed Entity Bean. I tried to access it from an external
client as described in the glassfish EJB
FAQ https://glassfish.dev.java.net/javaee5/ejb/EJB-FAQ.html
Here is the client program:
package RS;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.xml.parsers.*;
import org.apache.xml.serialize.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import RS.CourseHome;
import RS.CoursePK;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
import java.rmi.RemoteException;
import javax.rmi.*;
import java.util.Properties;
import Debug.*;
public class Client {
public static void main (String arg[]) throws IOException {
try {
InitialContext jndiContext = new InitialContext ();
Debug.P("jndic ongtext" + jndiContext);
Object o = jndiContext.lookup("RS.CourseHome");
Debug.P("looked up object "+o + "|"+o.getClass().getName());
RS.CourseHome home =
(RS.CourseHome)PortableRemoteObject.narrow(o,RS.CourseHome.class);
Debug.P("got home "+home);
Course C = home.create(1);
C.setName("blah");
CoursePK PK = new CoursePK();
PK.number=1;
C = home.findByPrimaryKey(PK);
Debug.P(C.getName());
catch (java.rmi.RemoteException re) {Debug.P("Remote Exception" + re.getMessage());}
catch (javax.naming.NamingException ne){Debug.P("Naming Exception"+ne.getMessage());}
catch (javax.ejb.CreateException ce){Debug.P("Create Exception"+ce.getMessage());}
catch (javax.ejb.FinderException fe){Debug.P("Finder Exception"+fe.getMessage());}
}Here is the error message:
Exception in thread "main" java.lang.ClassCastException
at com.sun.corba.ee.impl.javax.rmi.PortableRemoteObject.narrow
(PortableRemoteObject.java:294)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
at RS.Client.main(Client.java:26)The debugging indicates that I got the Initial Context
and got the object but the PortableObject.narrow failed:
jndic ongtextjavax.naming.InitialContext@1d85f79
looked up object IOR: (huge number deleted)
com.sun.corba.ee.impl.corba.CORBAObjectImplEarlier, I tried the version below, but based on the suggestion by Mr. Ebbert
in the forum started "Error When running the Client Program" by sree_devi,
I checked
the following. I went to "Jndi Tree Browsing" from the Administrative Console
and I found a "RS.CourseHome" entry under "ejb" I found RS.CourseHome there
but did not see the "Course" tghat I expected to see
Thus, I tried the version above:
package RS;
--- imports deleted for conciseness
import Debug.*;
public class Client {
public static void main (String arg[]) throws IOException {
try {
InitialContext jndiContext = new InitialContext ();
Object o = jndiContext.lookup("Course");
CourseHome home =
(CourseHome)PortableRemoteObject.narrow(o,CourseHome.class);
Course C = home.create(1);
C.setName("blah");
CoursePK PK = new CoursePK();
PK.number=1;
C = home.findByPrimaryKey(PK);
Debug.P(C.getName());
catch (java.rmi.RemoteException re) {Debug.P("Remote Exception" + re.getMessage());}
catch (javax.naming.NamingException ne){Debug.P("Naming Exception"+ne.getMessage());}
catch (javax.ejb.CreateException ce){Debug.P("Create Exception"+ce.getMessage());}
catch (javax.ejb.FinderException fe){Debug.P("Finder Exception"+fe.getMessage());}
}When I run it, I get the following Naming Exception: Course not found
I confirmed at the administrative console, that I have "Course" listed
under Enterprise Applications:
As per the ejb FAQ, I set up my $CLASSPATH so it starts as follows:
/opt/j2ee/SUNWappserver/lib/appserv-rt.jar:
/opt/j2ee/SUNWappserver/lib/javaee.jar:I also verifed in my domain.xml that the orb-listener-1, the default
naming service port was at 3700.
Here is the info on the Bean that I have running for both of the tries
at my Client code.

FAX 309 298 2302hi s-mcgowan,
"some other processing" comprises of printing of debug lines and publishing to the message queue using JMS. I added more debug lines so that i could see whats really happening... here is the result
myTableHome.create(...); <----------- no exception was thrown and it returned LocalMyTable object
print out "Insert successful"
print out "publishing message"
... publish message to message queue using JMS...
print out "Publish done"
... after few milliseconds...
java.sql.BatchUpdateException: Data exception -- row already exist in index PK_MYTABLE on table MYTABLE.
From the exception it seems like its doing a batch insert. So that seems to explain why the java.sql.BatchUpdateException is thrown few milliseconds after my call to myTableHome.create(...);
Is it possible to disable batch update / insert? how?
thanks in advance,

<appserver-install>/domains/domain1/server1/generated/ejb/j2ee-apps/<app-name>/<packages...>/
