How to use auto incremented tabe to create a CMP Entity Bean
hi,
I want create a CMP entitybean with an auto incremented table in
Oracel. So I need to know
- how to create a table with an auto-incremented field in oracel and
- how to change the create() method according to that.
I am using Sun studio enterprise for EJB developing.

For auto increment in Oracle you should use Sequence/Trigger combination.
And useful thread from EJB forum:

RE: Consuming and Creating a CMP Entity Bean
Hi There,
I have been trying to find an answer for 1 day. I don't know ehre to look next.
I am creating a CMP entity bean. I have created all the set and get mehtods as abstract functions. I have added a ejbCreate and a matching ejbPostCreate. The class code looks like this.
public abstract class COrderBean implements EntityBean {
protected EntityContext entctx;
//abstract declarations of property accessors
public abstract int getId();
public abstract void setId(int intid);
public abstract String getCustomerID();
public abstract void setCustomerID(String strcustomerid);
public abstract Date getDate();
public abstract void setDate(Date datorder);
public abstract String getNotes();
public abstract void setNotes(String strnotes);
public void ejbActivate() {}
public void ejbPassivate() {}
public void ejbRemove() {}
public void ejbLoad() {}
public void ejbStore() {}
public void setEntityContext(EntityContext context)
entctx = context;
public void unsetEntityContext()
entctx = null;
public COrderPK ejbCreate()
return null;
public COrderPK ejbCreate(int new_id, String new_customerid, Date new_order_date, String new_notes) throws CreateException
setId(new_id);
setCustomerID(new_customerid);
setDate(new_order_date);
setNotes(new_notes);
return new COrderPK(getId());
public void ejbPostCreate(int id, String customerid, Date order_date, String notes) {}
My client code works with both BMP entity beans and session beans. It is shown below. I am working with Sun's Application Server 8.0 and I created the database schema with the capture-schema.exe command.
Properties prps = new Properties();
props.put("javax.rmi.CORBA.UtilClass","com.sun.corba.ee.impl.javax.rmi.CORBA.Util");
props.put("org.omg.CORBA.ORBClass","com.sun.corba.ee.impl.orb.ORBImpl");
props.put("org.omg.CORBA.ORBSingletonClass","com.sun.corba.ee.impl.orb.ORBSingleton");
Context context = new InitialContext(props);
Object obj = context.lookup("corbaname:iiop:localhost:3700#COrderBean");
//Object obj = context.lookup("entitybean.OrderItem");
IOrderHome home = (IOrderHome)PortableRemoteObject.narrow(obj,Class.forName("ctaejb.entitybean.order.IOrderHome"));
//use create
IOrderRemote remote = home.findByPrimaryKey(new COrderPK(1));
System.out.println(remote.getDate().toString());
I am getting the follwing error. Can someone please help. Thanks in advance.

How to use "Auto increment" in temp table Oracle
Pleas tell me yaar,
In MS Sql for Auto increment i am using like this "seqid int identity" for temp table
t_seq_tbl table(seqid int identity,EVENT_SEQ_NO varchar(30))
In oracle how to use....As far as I know there is not any auto increment data type in Oracle. Instead of this you should create a sequence and get the next value of the sequence while creating a row in your table.
CREATE SEQUENCE Test_Sequence ;
CREATE TABLE Test_Table ( Id NUMBER , Foo VARCHAR2(4) ) ;
ALTER TABLE Test_Table ADD CONSTRAINT Test_Table_PK_Id PRIMARY KEY ( Id ) ;
INSERT INTO Test_Table ( Id , Information ) VALUES ( Test_Sequence.NEXTVAL , 'FOO' ) ; -
How to use auto-increment and search option for MS Access DB
Dear All,
I have configured our invoice in Adobe Livecycle and connected it to MS Acess 2007 as per http://forms.stefcameron.com/2006/09/18/connecting-a-form-to-a-database/.
All is working fine, I can insert, retrieve data from DB to invoice and vice versa.
Now I want few things to be implemented on our invoice.
When ever I open our invoice, it populate the first entry from DB, Is it possible to populate the last entry ?
Auto increment invoice number from MS Access DB every time we open our invoice after save.
How to implement search option from DB for invoice number ?
Please let me know if someone can provide me help on my scenario, so that I can share more stuff related to invoice and DB.
Look forward to hearing soon from experts and other team members.
Thanks & Regards

How to use auto increment with "nchar" data type
Hello
I have a table that I want the value in one column to be generated automatically with "T-XXX" pattern which
"XXX" is a number. Can Microsoft SQL Server do that?Hello,
Not directly.
You could use an integer column with "Identity" and then add a calculated column to generate the required pattern, like
'T' + convert(varchar, YourIntColumn)

Using a BLOB data type in a CMP Entity Bean: Error when send large files
I've successfully impleenting BLOB in my EJB. But the main prob is, it can only work on small file which is around 3K. Any larger files than that will caused error (refer below). I got info from a friend which is using normal JDBC call to insert a file into BLOB column that you can't use java.sql.Blob data type which will have this limitation. He suggested that by using oracle.sql.BLOB, this prob won't exist.
The problem is I'm unable to use oracle.sql.BLOB in my CMP EJB because in the jbosscmp-jdbc.xml, I'm able to specify the normal BLOB only which is java.sql.Blob (Refer below).
<cmp-field>
<field-name>attachment</field-name>
<column-name>attch</column-name>
<jdbc-type>BLOB</jdbc-type>
<sql-type>BLOB</sql-type>
</cmp-field>So, how do I solve this problem? I need to store files which the size is much bigger than that. I'm using JBoss 4 as my app server and Oracle 9i as my DB. I can see that there's many ppl facing this prob, but no solution to it. Pls advise. Thanks.

How to load the existing data from the databse in the CMP entity bean?
hello
my problem is as follows--
i am creating a CMP entity bean.in these beans client create the data instances using create() function.
now a entity bean will be created for the newly created data and it's EJBObject will also be formed.
now we will be able to perform finder methods over them.
remember these data has been newly created in the database.
but now if i want to perform the finder methods on the
existing data in the database( i don't need to use create() fn as i am not "creating" the data.). how will i perform the query over the existing data.
basically i have to make a CMP bean to extract the data corresponding to a particular condition , from the database table. i don't want to create the data in the database but just find out what data satisfies my condition.
thanking you
Prashantyou have to use findByXXX methods. depending on your appserver you may have to declare them (and eventually the query you want to be used) in the vendor specific deploiement descriptor.
(e.g. using jboss i don't remember having explicitly declare the findBySomeField method - where someField is a persistent field - in the dd, whereas with bas all finder methods have to be explicitly declared)
[note that obviously these methods have to be present in your home interface] -
I'm trying to learn how to use Xcode. I've create a simple Hide App app from a youtube video tut, but I can't get it to export with the icon I've chosen. Any clues why?
We didn't do that video. Why are you asking here?
Those videos are usually outdated....

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.
VadiHello ,
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();

How to use same transaction when calling CMP entity beans and DAO (JDBC)
We are currently using Weblogic 8.1 SP2 with an Oracle 10g database (using XA thin and non-XA drivers).
We have a session bean that invokes an entity bean and a DAO (data access object pattern) in order to add data in 2 separate tables (account and history). Rows are added to the first (account) table using a CMP Entity bean while inserts are done in the 2nd (history) table using a DAO. Here is some pseudo code:
addHistorySessionBean (trans-attribute="Required")
begin
Step #1 - call addAccountEntityBean (trans- attribute="Required")
Step #2 - call addHistoryDAO (get datasource, connection)
end
The 2nd table (history) has a foreign key constraint to ensure that the corresponding key exists in the first (account) table. Unfortunately, DAO inserts on the 2nd (history) table fail with a foreign key constraint violation (INTEGRITY CONSTRAINT VIOLATION - PARENT KEY NOT FOUND!) since they cannot see the row added to the 1st (account) table in step #1 by the CMP entity bean.
How does one ensure that all this is done in a single transaction ? It appears that the app server creates two seperate transactions (one for the session bean facade and the entity bean and a 2nd transaction (when we retrieve a connection using the same data source JNDI name) for the DAO.
A post on server side suggested using a "<resource-ref>" in the session bean to tie the two potentially separate transactions together, but that does not work for us. However, I am not sure if we are doing that correctly. After we define the resource ref in the session facade bean, do we use the resource ref "name" attribute to lookup the datasource or do we still lookup the datasource by JNDI name ? Do we need to define the resource-ref tag in the entity bean also ?
Does Weblogic allow using a single transaction for this type of a scenario ? How does one specify within Weblogic that the same transaction should be utilized by the entity bean and any subsequent DAOs?
People have also suggested that we defer constraint checking until the transaction(s) are committed but that sounds like a work acount without addressing this issue. Would postponing the constraint checking in Oracle cause any additional overhead ?
Any suggestions with specific examples or documentation on how to address this issue will be gratefully appreciated.Thanks for your suggestion. Unfortunately, this does not work since it appears that there are 2 separate transactions going on here. One, the original one initiated by the session bean and used by the entity bean and the other initiated by the DAO. Any other ideas appreciated.
Hi,
Try setting the delay-database-inserts tag to
ejbCreate in RDBMS descriptor file.

Using a CMP Entity Bean local stub as a field of another CMP Entity Bean
Hello,
Is it possible to implement a field of a CMP Entity bean as another CMP Entity bean and how is it done?
I've seen a pseudo code for this in Ed Roman's Mastering EJBs, second edition, but I can't seem to get it to work (pages: 330 - 1:1 using CMP and 339 - fake M:N using CMP).
I'm using SUN ONE Application Sever 7. Is this server capable of this?
I'm trying to implement a fake M:N relationship using 3 beans: 2 for each side of the relationship and one as the "bridge" table.
For example, the two beans on each side of the relationship are SubscriberBean, SubscriptionBean and the "bridge: bean is SubscriberSubscriptionBean. The SubscriberSubscriptionBean has two fields: SubscriberLocal stub and SubscriptionLocal stub.
Please let me know if you need more information to answer this question.
Thanks.
NikolaIm sorry but i dont know about the example you are talking about. I kinda learn
all those techniques from forums, articles and tutorials because book often suffer from
not having the information im mostly looking for.
As far as i understand you, you want to implement a bridge been, which is representing a row in a join table. So that if one side of the relation is deleted the join-table entry (your bridge-CMP-Bean) is cascaded. Right?
First of all the simple part: (My approach)
- The joint table is foreign keys only - without a relation description. -
In this case you dont have to implement a bridge bean. Because it just wouldnt represent anything of sense.
Lets think of an entity/table USER whith the columns name (PRIMARY KEY), and prename.
Our second entity/table is ADDRESS with the columns road (PRIMARY KEY) and housenr.
The join table is simply: USER_ADDRESS with fk_name (FOREIGN KEY) and fk_road (FOREIGN KEY) both on CASCADE DELETE. So if the address is deleted the mapping entry is deleted, too same for the user part:
USER -> USER_ADDRESS <- ADDRESS.
Our entity Beans are called User and Address in class-names JNDI-names and names.
Now we want to create the CMR mapping so we can access the addresses of a user from the user bean directly. The methods on the user side are:
public abstract Collection getAddresses();
and
public abstract void setAddresses(Collection new_addresses);
the xdoclet comments on the User side are (for the getter only)
* @ejb.interface-method
* @ejb.relation
* name = "User-has-Addresses"
* role-name = "User-Addresses"
* target-ejb = "Address"
* target-multiple = "true"
* @sunone.relation
* column="USER_ADDRESS.fk_name"
* target="USER_ADDRESS.fk_road"
public abstract Collection getAddresses();
for the other side of the relation we define in the Address-Entity
public abstract Collection getUsers();
and
public void setUsers(Collection users);
the xdoclet comments on the Address side are (for the getter only)
* @ejb.interface-method
* @ejb.relation
* name = "User-has-Addresses"
* role-name = "Address-User"
* target-ejb = "User"
* target-multiple = "true"
* @sunone.relation
* target="USER_ADDRESS.fk_road"
* column="USER_ADDRESS.fk_name"
As we dont want the user or address to be deleted if the other side of the relation is deleted we dont specify cascade-delete="yes" in the ejb.relation namespace.
The sun-cmp-mappings.xml should now look like this:
(For the User - side)
<!-- Relationship User-has-Addresses, role User-Addresses -->
<cmr-field-mapping>
<cmr-field-name>addresses</cmr-field-name>
<column-pair>
<column-name>USER_ADDRESS.fk_name</column-name>
<column-name>USER_ADDRESS.fk_road</column-name>
</column-pair>
</cmr-field-mapping>
and similar on the Address-Side:
<cmr-field-mapping>
<cmr-field-name>users</cmr-field-name>
<column-pair>
<column-name>USER_ADDRESS.fk_road</column-name>
<column-name>USER_ADDRESS.fk_name>/column-name>

Dont forget that all elements in the Collection must be of the right Interface-type.
First of all the harder part:
Now what you might want is when the relation has some information specified like user live at address and is tenant or facility manager.
The, in the first step you will have to implement the UserAddressRelation entity which will have to CMR fields of the 1:N type.(Just as you wish)
Lets think of the example above extended by the relation type. Our relation bean is named UserAddressRelation.
Now User has the methods as above but the classes in the Collection must now be of the UserAddressRelationLocal/Remote interface and not AddressLocal/Remote-interface.
You will have to change the xdoclet comment to:
* @ejb.interface-method
* @ejb.relation
* name = "User-has-Addresses"
* role-name = "User-Address"
* target-ejb = "UserAddressRelation"
* target-multiple = "true"
* @sunone.relation
* target="USER_ADDRESS.fk_name"
* column="USER.name"
So we now dont reference the other side bean directly. We reference the relation EntityBean. Do the similar changes on the other side.
In particular you will have to specify 4 CMR mappings now:
1. User to UserAddressRelation 1:N
2. UserAddressRelation N:1
3. Address to UserAddressRelation 1:N
4. UserAddressRelation N:1
Which i dont want to explain in detail now because its kinda all the same as above.
Now you cann access the Addresses of a user in the way.
UserLocal.getAddresses(); <- !you get the mappings!
UserLocal.getAddresses().item(0).getAddress() <- you get the address (this is dirty coding just for understanding)
UserLocal.getAddresses().item(0).getUserRole() <. you get the role of the user at this address.
Hope this helped you. You are welcome to ask any detailed question. -
How to disable cache implementation in 8.1 SP6 for entity beans
How to disable cache implementation in 8.1 SP6 for entity beans
In our production environment, we want to disable cache implementation for entity beans. We are using weblogic 8.1 SP6.
Weblogic cache implementation has been causing many cachefull exceptions so we want that it fetches the data from database everytime instead of cache.Check the "max-beans-in-cache" setting in your weblogic-ejb-jar.xml. The cache full exception, means that a new bean could not be created because of this cache being full.
Nothing to do with fetching from the database directly.
If you really want direct fetches then do not use beans at all. Consider using direct JDCB/SQL calls (without a entity bean) to fetch huge data.
Let's again review your application based on the below explanation before making a decision on which configuration change to perform:
If you truly have many ejbs simultaneously enrolled in transactions, then yes, the cache must be big enough to hold all the instances.
Your cache must have a max size large enough to handle your peak simultaneous transaction load.
Also, try to ask the following query to your application developer. Does every user actually have to have more than one bean in the cache ? Are many of these values read-only reference values that are not updated ?
SOLUTION CHOICE:
1. If you are testing with more number of users simultaneously, then you will need to increase the "max-beans-in-cache" setting in your weblogic-ejb-jar.xml to match the load.
2. If you have few users but still seeing a lot of beans, then consult with your application developer and try to ask the above questions (Does every user have more than......) and based on that try to redesign/tune your application to make it an effective Entity bean model.
3. If you have queries where huge result sets are returned, consider using plain/direct JDB/SQL calls.

Help:How to manage relationships in CMP Entity beans
Hi everybody;
I am using Oracle JDeveloper 9i release 2 and Oracle 9i database.
How can I manage one-to-many and many-to-many relationships in a CMP Entity Bean, I tried to managed the relationships in code, calling the beans, searching for records, making loops and joining.
Is there a better way to manage the relationships with out doing this in code?
Because I think it is not good for performance.
