Entity Beans in Oracle 8.1.6

Does the Oracle 8.1.6 version support the Entity Beans?
I have tried to create an EntityBean thru JDeveloper3.1 and it posts a message that they are not supported.
Any info?
Thanks in advance
[email protected]

Version 8.1.7 will support them.

CMP Entity Beans in Oracle 9iAS

Hi!
I've deployed entity beans into Oracle 9iAS, but keep getting the following error each time I try to lookup the bean:
"javax.naming.NamingException: Unknown reasons [Root exception is org.omg.CORBA.UNKNOWN: minor code: 16 completed: Maybe]"
The JNDI name of the bean are ok and I'm calling it correctly. I'm calling my a Session Bean in a similar way and it works fine.
I'm using JDevloper 3.2.3 to deploy the beans and OAS version is 1.0.2.2.
Thanks for any advices,
Sebastian

gday -
OC4J implements major portion of the EJB 2.0 PFD1 specification.
It supports the new container contract and persistence model in PFD1, along with associated new XML DD tags, so yes, it does support abstract implementation EJB classes and abstract accessors definitions.
It does not support the latest EJB 2.0 PFD2 modifications and also does not support the local/remote interface model, EJB-QL, home methods, etc.
cheers!

To use Entity Bean or Oracle stored Package?

Currently, in my project, Weblogic8.1 and Oracle is used, but lots of business logic is implemented using Oracle stored Packages, many of these packages have a package level readonly lookup table(like index-by table or nested table), which is populated with data from database, once the package is called, and is accessed very often in subsequent calls of stored procedures.
Since, in Weblogic server, a connection pool is maintained, and those package level lookup tables would be stored as session data in oracle PGA, I'm afraid this might cause oracle database server to be overloaded.
to fully take advantage of middleware cache service that weblogic provide, should I move those business logic out of oracle and implement them using like read only entity bean?
any help appreciated!

Its very hard to say without knowing the usage patterns of the data. It sounds like you have a lot of read-only entities. These could be spread around a WLS cluster, therefore there is more scalability and performance with this option. However, I would not neccessarily rewrite business logic from SP into EJB just for middle-tier caching.
If its a DB intensive app with lots of SQL, then if the calls are within SP's, there is only 1 call from WLS and the DBA ought o be able to tune the DB usin read-ahead and other DBA semantics. If there is locality of reference in the data, again, DB can use read-ahead better than WLS, although RO cache in middle is more scalable than DBMS.
I wouldnt rewrite business logic from SP to EJB/Entity beans to take advantage of cache, especially if there is no locality of read-only reference to data. Oracle could do this better in my opinion, especially if SP's already exist
Need for information on the usage patterns of the data - how is it CRUD'd.
I would use-case the steel threads and put them under test load to see if the SP's really are an issue, since this is an architecture decision. What state is the project at? Live/Dev? Inception?

WLS 8.1 - Entity Beans CMP - Oracle 10g Audit Tool

Hi,
We are defining the architecture of a new application on WebLogic Server 8.1 and Oracle 10g.
We are thinking in using CMP Entity Beans and we need to integrate our system with Oracle Audit Tool.
Can anybody give us some information about this issue ?
Thanks,
Javier Cano

I really don't see the point of using CMP with an expensive, fully featured database like Oracle. MySQL or a flat file maybe. Otherwise it is just a waste of purchased resources.

Generate entity bean from Oracle view fails

Hello,
is it possible to create an Entity Bean (v3) from an Oracle View in jDev (Build JDEVADF_11.1.1.1.0_GENERIC_090615.0017.5407)?
In the wizard I can see my view, select it, specify all the info/details about it, but when clicking 'Finish' I see the "EJB Log" window appearing empty and the entity bean is not created. Already tried it in two different PCs without success.
thanks!

You can rename EJB and EJB classes (refactor) by right-clicking on the EJB node in
project navigagor and selecting "Rename EJB and EJB Classes"
In the dialog box you would get an option to refactor classes.

Problem while deploying entity beans

Hi,
We are using JDeveloper 3.2.2 (NT) and 8.1.7 (NT) to deploy EJB's.
Now we are trying to deploy the entity bean to Oracle JVM. We are facing the following problem while deploying an entity bean .
"Persistence provider declared in the deployment descriptor is not supported
*** Errors occurred while deploying the EJB to 8i JVM ***
*** Deployment completed ***"
We would appreciate if anyone could help us to solve this error.
null

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?

Jinal Shah

CMP entity beans from tables in 9.0.3 jdev preview

I am trying to generate CMP entity beans from oracle tables using 9.0.3 jdeveloper preview. My oracle db version is 9.2. I notice that if a table has a single column primary key, no xxxPK.java file is created. However, if the primary key is multi-column an xxxPK.java file is created. Is this correct behavior? I expected an xxxPK.java file to be created regardless of the number of columns in the primary key for the table. Has anyone else noticed this? I am new to EJB so forgive my ignorance.

Comparing to JDev 902, I think this is a much better decision. Having to change beans with a single field PK to not using a custon PK class, to avoid using that class was a pain in JDev 902. There4s little benefit in using a custom class when there4s only a single field in it... some will say that it prevents having to do majot changes to your code if the PK changes in the future and add another field. But a careful database design will void this almost completely. So having JDev 903 use a java native class is a better option in this situation. At least from my personal point of view.

How to specify JDBC Oracle url using deployment tool - Entity Bean

Hello I'am new to EJB.
When creating a entity bean-managed persistence and you need to specify the jdbc url with user name
and password to establish a connection object, how does one specify that in the deployment
tool?
Heres an example of what has in the J2EE tutorial has in AccountEJB to get an connection object
private String dbName = "java:comp/env/jdbc/AccountDB";
private void makeConnection() throws NamingException, SQLException {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(dbName);
con = ds.getConnection();
Now if my oracle jdbc url is to be jdbc:oracle:thin:@Abe:1521:dev
ie My host is Abe, port number 1521 and database name of dev and username/password will be system/manager.
what would my dbName be at the top?
Would my JNDI lookup of a DataSource resource "java:comp/env/jdbc/AccountDB" become "java:comp/env/jdbc/dev" for starters?
In the Resource Factories Reference Code I've add a reference of
Coded Name: jdbc/dev
Type: javax.sql.DataSource
Authentication: Container
and down the bottom of the I've put JNDI Name: MyAccount
according to the AccountClient code of:
Context initial = new InitialContext();
Object objref = initial.lookup("MyAccount");
and put User Name of "system" and Password of "manager"
I'am sure in the source code I have to put
Class.forName("oracle.jdbc.driver.OracleDriver")
else you would get that no sutitable driver error, maybe you don't have to if ejb server is smart enough?
What I'am confuse about is where to specify the jdbc url of "jdbc:oracle:thin:@Abe:1521:dev" ??
Know it won't work because of this vital part. Do you have to put that somewhere else in the deployment tool or properties file, or some other tool??
Please help
Thanks
Abraham Khalil

One thing I don't like about EJB is that everything is transparent which is good! But its much
harder to debug! :( Tried to see if I can figure it out. Hope someone has seen this problem before?

Problems accessing tables in oracle database with ejb entity bean

I have created a simple server application that uses an entity bean (version 2.0) for an existing table in oracle database, and a session bean that is used as an outside interface for performing operations on that table.
after deploying the server and client application the client attempts to perform an operation with the session bean remote interface it obtained.
The session bean uses a locale interface to communicate with the entity bean, but when it tries to use its methods (create, findByXXX) it always get the following Exception: java.sql.SQLException: ORA-00942: table or view does not exist.
the table of course exists, and the username password I'm using has all the permissions needed for this table.
note - I'm using the Forte enterprise edition 4.0 as developer tool.
I'll be glad to get some help.
Here is the full stack trace of the exception:

Well it seems like the problems has a simple explanation. The Forte assigns a default table name (<entityName>EJBTable) when creating an entity bean from an existsing table in DB (which is not the same as the one it was created from !!!). Also, for reason unknown, when you deploy these entity beans, it doesn't even create the new table under its new name (even if instructed to).
So using the Forte we managed to use successfuly only entity beans that were created "from scretch" (when deployed their tables are created).
Does anyone know how to change the default name the Forte uses, and make it work properly with entity beans created from an existsing table (without going over the xml's) ?

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

Not 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

Hi,
Just run the db_setup.sh script located in the bin directory of ias
If you just give the Oracle Home directory the libraries will be found.
Register a Datasource pointing to the service you defined in tnsnames.ora
Cheers, Robert

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?

Using oracle db sequence for auto generating of PKs for CMP entity beans

Hi,
I have read quite a number of threads about (auto) generation of keys for primary keys for the CMP entity beans.
My requirement is I am migrating an application deployed on Weblogic to oc4j. The application is using cmp entity beans with auto key generation using a sequence in the Oracle db. This is specified in weblogic-cmp-rdbms-jar.xml file like below:
<automatic-key-generation>
<generator-type>Oracle</generator-type>
<generator-name>REPUSER.DEPT_REPORT_SEQ</generator-name>
<key-cache-size>1</key-cache-size>
</automatic-key-generation>
In the ejb-jar.xml, it is specified as:
<prim-key-class>java.lang.Integer</prim-key-class>
<primkey-field>id</primkey-field>
Now, I need to migrate this to oc4j. Can somebody suggest me options and clarify my questions kindly?
1) I have read articles that say that in the ejb-jar.xml, we need to specify <prim-key-class>java.lang.Object</prim-key-class> and this will create a column called 'autoid' in the respective entity table in the Oracle db.
- How can I use this to assign the value to my primary field, say, id?
2) Now, with the latest oc4j, can I use Oracle database sequence as the key generator for the values of the PKs just by specifying in the xml descriptor ejb-jar.xml?
2.a) If yes, is there any article that explains with the code?
2.b) If no, what are the alternatives I have?
I have read many discussions that say that we can create a stateless session bean that can lookup the database sequence using simple JDBC call to return the nextval of the sequence. The SSB should be called in the ejbCreate() of the entity bean.
My related question is, what is recommended for oc4j? What are limitations of the various options for the latest oc4j available?
How should I go about deploying this kind of ejbs in oc4j?
Any help and pointers are welcome. Please help.
Thanks a lot.

Hello ,
Instead of exposing a get/set method for each arribute of your bean (corresponding to database table) expose only one object.
For example
public class CustomerBean implements javax.ejb.EntityBean{
private CustomerVO objCustomer;
private String customerName;
private String customerMail;
private String customerType;
public CustomerVO getCustomer(){
return this.objCustomer;
public void setCustomer(CustomerVO objCustomer){
this.objCustomer = objCustomer;
public void ejbStore(){
customerName = objCustomer.getName();
customerMail = objCustomer.getMail();
customerType = objCustomer.getType();

Timeout of session / entity bean

Hi all
We are facing "RollbackException: The transaction has been marked for rollback (timed out)" excpetion. please help us in resolving this.
Here is problem description.
Code Description:
Step1: Action class calls Session bean
Step2:Session Bean does three things
A. Reads various value from database and write it to fileOutputStream
B. Generate a Sequence number using Sequence
C. Call create method of Entity Bean by local reference to insert the created file (in step 2A) in database as blob
As per our observation session bean takes around 20-30 sec in processing 2A and 2B.

We have tried out .....
- Making new Enity Bean
- changing timeout of session bean by changing it in properties
<session-deployment name="TariffSessionEJB" timeout="300" >
We are using Oracle 10g application Sever and Oracle 10.1 database.

Assuming you are using either 9.0.4 or 10.1.2, please note that default transaction time out is 30s and you can change that <transaction-config> element in server.xml. This is specified in millliseconds

How do I create an Entity Bean with unknown primary keys

Hi,
Can a good folk help me.
I am mapping an entity bean to an oracle table for the purpose of logging . I do not need a primary key contraint on this table. How do I specify in my entity bean file descriptor not to use any field for primary key ...
I have done this so far...
in my ejb.xml file - I set....
<prim-key-class>java.lang.Object</prim-key-class>
and deleted ....
<primkey-field>...</primkey-field>
My table structure is .....
CREATE TABLE FAMS_REQUEST_LOG (
EDITEDBY VARCHAR2(20),
OLDTRANSDATE DATE,
REQUESTID VARCHAR2(30) NOT NULL,
OLDQTY NUMBER(20),
NEWQTY NUMBER(20),
NEWTRANSDATE DATE)
but I still get this error message on deploying...

you will have to create a sequence and a trigger
CREATE SEQUENCE <SEQUENCE NAME>
INCREMENT BY 1
START WITH 1
NOCACHE
/this sequence will guarantee that each requested number is unique
the trigger will select from this sequence and insert the obtained value in the new record
CREATE OR REPLACE TRIGGER <TRIGGER NAME>
BEFORE INSERT ON <TABLE NAME>
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
    BEGIN
        select
            <SEQUENCE NAME>.nextval
        into
            :NEW.<COLUMN NAME>
        from
            dual;
    END;
[/CODE]
this will always take the value from the sequence, even if you already provided a value yourself
(otherwise you will first have to test if :NEW.<column name> is null, but I wouldn't do this for a key column.
if you need the generated key back for further processing (inserting it into a child table for example), you can use the returning clause on the insert statement
see the oracle documentation for more information about sequences, triggers and the returning clause

I am new to Oracle and need to know how to create a table that uses an automatic incrementation on a primay key for it's default. I need the uniqueness automatically managed by the DBMS.. This activity is know as setting the Column (primary key with identity) in Ms-SQL..
Your help would be appreciated greatly....
Thanks....
