i am having problems deploying CMP Entity Beans in petstore 1.3 where theprimary
key class is defined as java.lang.Object in the ejb-jar.xml descriptor(<prim-key-class>java.lang.Object</prim-key-class>).
Does weblogic 6.1 with 1.3 features enabled support the above feature.
Thanks,

Error Deploying CMP Entity Bean

Hi,
I am new to Entity Beans and am trying to deploy a CMP Entity Bean without any success.
I did search this forum for similar issues and tried those suggestions as well but that has not helped. Was wondering if someone could help me out on this.
The Entity bean has 2 fields: name and description.
The ejb-jar.xml file for this bean is:
<enterprise-beans>
<entity>
<ejb-name>Product</ejb-name>
<home>example.cmp.ProductHome</home>
<remote>example.cmp.Product</remote>
<ejb-class>example.cmp.ProductBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.String</prim-key-class>
<reentrant>false</reentrant>
<cmp-version>2.x</cmp-version>
<abstract-schema-name>PRODUCTS</abstract-schema-name>
<cmp-field>
<field-name>name</field-name>
</cmp-field>
<cmp-field>
<field-name>description</field-name>
</cmp-field>
<primkey-field>name</primkey-field>
<query>
</query>
</entity>
</enterprise-beans>
The error that I get while deploying the bean is:

Please note that the data-source has been re-architectured in 10.1.3 DP3 and you should have DataSource as follows:
<data-sources xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:noNamespaceSchemaLocation='http://xmlns.oracle.com/oracleas/schema/data-sources-10_1.xsd' schema-major-version='10' schema-minor-version='1'>

Error in deploying CMP Entity Beans

Hello,
When I created a CMP Entity Bean using the JDeveloper Release Candidate and try to deploy it I get the following message:
Auto-creating table: create table POGROUP_PRESS_RELEASE (press_release_id integer not null primary key, press_release_date varchar (255) null, title varchar (255) null, time varchar (255) null, release_type varchar (255) null, URL VARCHAR2(100))
Warning: Error creating table: ORA-00955: name is already used by an existing object
What does this mean? Does it mean that this bean cannot be deployed. If the table already exists in the database shouldn't it use the table instead of trying to create the table?
Any help would be appreciated,
Gopi

initialize "table" attribute of <entity-deployment> element to POGROUP_PRESS_RELEASE.This will prevent auto-create functionality of OC4J.
However this <entity-deployment> tag present only in orion-ejb-jar.xml.So you have to create this file and include along with ejb-jar.xml in jar file.
Sample orion-ejb-jar.xml looks like this....
<orion-ejb-jar deployment-version="1.0.2.2" deployment-time="ea013a2eda">
<enterprise-beans>
<entity-deployment name="TestHome" location="TestHome" wrapper="TestHome_EntityHomeWrapper5" table="POGROUP_PRESS_RELEASE" data-source="jdbc/OracleDS">
<primkey-mapping>
<cmp-field-mapping name="m_ID" persistence-name="ID" />
</primkey-mapping>
<resource-ref-mapping name="jdbc/OracleCoreDS" />
</entity-deployment>
</enterprise-beans>
</entity-deployment>
</orion-ejb-jar>
For complete DTD :

Hope this helps.....

Deploying CMP entity bean throws compilation error.

Jdeveloper build works fine but the server deployment ( embedded) fails. I linked tools.jar to j2ee home dir, same version as jdev uses. Session beans deploy OK.
The table corr to the entity bean has a primary key and the entity bean was created by dragging-dropping table onto UML diagram.
error is >>>cmp-field of type 'java.lang.Long' does not have a no-arg constructor which is needed for properties/fields based mapping<<<, message details follow after dashed line.

Help: Deploying CMP Entity Bean on Jboss (DB2)

Hi, I have a problem which I have tried to solve for a couple of days now with now success.
I have deployed an ordinary Entity CMP Bean which name is Customer.
This bean has 2 fields, an id field and a customername field.
I use DB2 where the table is named customer and the fields are named as the fields in the bean, id and customername.
I have configured the db2-ds.xml file as follows, and put it in %jboss%\server\default\deploy:
<local-tx-datasource>
<jndi-name>DB2DS</jndi-name>
<connection-url>jdbc:db2://192.168.10.220:6789/business</connection-url>
<driver-class>COM.ibm.db2.jdbc.net.DB2Driver</driver-class>
<user-name>db2admin</user-name>
fuck4future
<min-pool-size>5</min-pool-size>
<max-pool-size>25</max-pool-size>



<type-mapping>DB2</type-mapping>
</local-tx-datasource>
I have created the jbosscmp-jdbc.xml file and put it in the META-INF directory in my ejb-application:
<jbosscmp-jdbc>
DB2DS

<create-table>false</create-table>
<enterprise-beans>
<ejb-name>Customer</ejb-name>
<table-name>customers</table-name>
<cmp-field>
<field-name>id</field-name>
<column-name>id</column-name>
</cmp-field>
<cmp-field>
<field-name>companyname</field-name>
<column-name>companyname</column-name>
</cmp-field>
</enterprise-beans>
</jbosscmp-jdbc>
I have created the standardjaws.xml also in my META-INF directory of the ejb application. This file contains a lot of information (type-mappings), and starts with:
java:/DB2DS
<type-mapping>DB2</type-mapping>
false
I have the ejb-jar.xml file automaticly generated for me in my developer tool (WSAD).
When I try to start my server I get the following error:
ObjectName: jboss.j2ee:jndiName=Customer,service=EJB
state: FAILED
Depends On Me: org.jboss.deployment.DeploymentException: type-mapping is not initialized: DB2DS was not deployed or type-mapping was not configured.
ObjectName: jboss.j2ee:service=EJB,plugin=pool,jndiName=Customer
etc.......
Please can someone help me and give me a clue, what am I doing wrong??

How to deploy CMP entity bean 2.0 ?

Dear all,
How should I write the EJB-QL for all the finder methods in my home bean during deployment? I�m using the j2sdkee-1_3_01-win to test out this bean. I have tried the following query:
SELECT OBJECT(a) FROM ProductBean AS a WHERE basePrice > ?1 but when I try to verify the bean, an error message appeared:
Error: [ SELECT OBJECT(a) FROM ProductBean AS a WHERE basePrice > ?1 ] has parsing error(s)
Here is the detail:
Test Name: tests.ejb.entity.ejbql.EjbQLFromCmpEntityDescriptor
Test Assertion: EJB 2.0 Spec Chapter 10 Container managed persistent queries should comply with specification in its sytax and semantic rules
Detailed Messages:
Error: [ SELECT OBJECT(a) FROM ProductBean AS a WHERE basePrice > ?1 ] has parsing error(s)

Hope this is not too late...
SELECT OBJECT(a) FROM ProductBean AS a WHERE a.basePrice > ?1

Error While Deploying A CMP Entity Bean With A Composite Primary Key

Hello all,
I have a problem deploying CMP Entity beans with composite primary keys. I have a CMP Entity Bean, which contains a composite primary key composed of two local stubs. If you know more about this please respond to my post on the EJB forum (subject: CMP Bean Local Stub as a Field of a Primary Key Class).
In the mean time, can you please tell me what following error message means and how to resolve it? From what I understand it might be a problem with Sun ONE AS 7, but I would like to make sure it's not me doing something wrong.
[05/Jan/2005:12:49:03] WARNING ( 1896):      Validation error in bean CustomerSubscription: The type of non-static field customer of the key class
test.subscription.CustomerSubscriptionCMP_1530383317_JDOState$Oid must be primitive or must implement java.io.Serializable.
     Update the type of the key class field.
     Warning: All primary key columns in primary table CustomerSubscription of the bean corresponding to the generated class test.subscription.CustomerSubscriptionCMP_1530383317_JDOState must be mapped to key fields.
     Map the following primary key columns to key fields: CustomerSubscription.CustomerEmail,CustomerSubscription.SubscriptionType. If you already have fields mapped to these columns, verify that they are key fields.Is it enough that a primary key class be serializable or all fields have to implement Serializable or be a primitive?
Please let me know if you need more information to answer my question.
Thanks.
Nikola

Hi Nikola,
There are several problems with your CMP bean.
1. Fields of a Primary Key Class must be a subset of CMP fields, so yes, they must be either a primitive or a Serializable type.
2. Sun Application Server does not support Primary Key fields of an arbitrary Serializable type (i.e. those that will be stored
as BLOB in the database), but only primitives, Java wrappers, String, and Date/Time types.
Do you try to use stubs instead of relationships or for some other reason?
If it's the former - look at the CMR fields.
If it's the latter, I suggest to store these fields as regular CMP fields and use some other value as the PK. If you prefer that
the CMP container generates the PK values, use the Unknown
PrimaryKey feature.

Bad Performance/OutOfMemory Error in CMP Entity Bean with Large DB

Hello:
I have an CMP Entity deployed on WLS 7.0
The entity bean maps to a table that has 97,480 records.
It has a finder: findAll() -- SELECT OBJECT(e) FROM Equipment e
I have a JSP client that invokes the findALL()
The performance is very poor ~ 150 seconds just to perform the findAll() - (Benchmark
from within the JSP code)
If more than one simultaneous call is made then I get outOfMemory Error.
WLS is started with max memory of 512MB
EJB is deployed with <max-beans-in-cache>100000</max-beans-in-cache>
(without max-beans-in-cache directive the performance is worse)
Is there any documentation available to help us in deploying CMP Entity Beans
with very large number of records (instances) ?
Any help is greatly appreciated.
Regards
Rajan

Hi
You should use a Select Method, it does support cursors.
Or a Home Select Method combination.

Help about Date and Time by CMP entity bean

I should have two fields in my cmp .one stores current date ,another one stores current time while ejbcreate();
I should be able to get findmethod findobjectBetween ?! and ?2
or that sorts of find method.what type of the method should I use.
java.util.Date or Simply String?
if I use java.tuil.Date as the type.
How shoud my ejbcreate method look like?
public abstract void setDate(Date mydate);
public abstract Date getDate();
ejbCreate(String name,String password,Date mydate,Date mytime)
setDate()
I suppose I use write a business method getCurrentDate() which uses
java.util.Date().toLocale,But I think it just returns String
help pls.

If you can have a look at a cmp example in the samples that ship with the server. My guess is that the weblogic-ejb-jar.xml file is missing the <persistence-use> element which for 810 would look like:
<persistence>
<persistence-use>
<type-identifier>WebLogic_CMP_RDBMS</type-identifier>
<type-version>7.0</type-version>
<type-storage>META-INF/weblogic-cmp-rdbms-jar.xml</type-storage>
</persistence-use>
</persistence>
I seem to recall that the elements might be slightly different in structure for the wls700 version of the DTD, so please check that (I cannot, I'm at home and don't have everything here).
Give that a try and see if it doesn't solve your compilation failure.
Also, the compilation should not be throwing a null pointer exception in a case like that, I consider that to be a bug.

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();

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.
