Did elationship fields in entity bean with CMP same as foreign key in table
did elationship fields in entity bean with CMP same as foreign key in table database.so we don't have to make some foreign key column in table database.
did Container handle that both.
I need some answer
thank's
Suppose you have Group and user entity. Relation is 1-m. One group many users. When you create user, you dont need to send group id, All you need is create user and add it in collection (cmr-field) in group(user belongs to). Container will add its group id in user entity as well as in db.

Entity bean with another class as primary key generator class
Hi All,
I have a CMP entity bean in which I generate the primary key using my own class know as unique id generator.
I use it in ejbCreate method in the following manner
public Long ejbCreate(HospitalData hospitalData) throws CreateException{
Long myid = new Long(UniqueIdGenerator.getId());
System.out.println("My id generated ====== "+myid);
this.hospitalid = myid;
System.out.println("My id generated ====== "+this.hospitalid);
System.out.println("Came in ejbCreate method of HospitalEJB");
this.hospitalname = hospitalData.getHospitalname();
return null;
Can you tell me how I map this primary key in my ejb-jar.xml and jbosscmp-jdbc.xml.
Anyhelp would be appreciated.
Thanks

I am trying to develop an entity bean attached to a key which have a
composite key using Primary Key Class. When I use the findByPrimaryKey
method of the bean it throws an exception as follows,I notice that you are using the reference CMP plugin.
at com.netscape.server.ejb.SQLPersistenceManager.find(Unknown Source)I'm also willing to bet that you may have created your own primary key class
with a single field, rather than using the fields type as a primitive
primary key class. If you do this, then SQLPersistenceManager will break.
It is badly written, and has some stupid assumptions. The one I remember
the most is that if you only have one primary key field, then
SQLPersistenceManager assumes you have used a primitive type such as
java.lang.String or java.lang.Integer, to represent it, rather than creating
your own <Enity>Pk.java file.
SQLPersistenceManager works for toy examples, but in general I would say it
is broken and unusable. Either use BMP, or splash out the money for Coco
Base from Thought Inc. Currently the only CMP plugin for iPlanet App server,
other than the reference implementation, that I know of. -

..Hi Juan,
Sounds like you've defined either a java.lang.String where it should have
said Java.util.Vector (or the other way around) in the part of the
deployment descriptor that defines your custom finder method parameter.

Is it possible to map the cmp fields of the entity bean with out dictionary
Dear sirs,
I have created the EJB project module and WEB Module. Now i have to map the CMP fields of the entity bean to the underlying table. Is it possible to map the cmp fields of the entity bean with out java dictionary? If yes how can we do that.
I have got some error while mapping an EJB's CMP fields to the table through dictionary. I was actually intended to map 79 fields but it gives an error that more than 64 fields are not allowed while building the dictionary.
1. Can you tell me what could be the possible reason?
2. Is it possible to map the cmp fields of the entity bean with out java dictionary? If yes how can we do that.
Kindly helo me,
Sudheesh K SHi,
Sudheesh please check up if the below link helps,there are other ways of writing the persistent.xml for container managed entity bean.
http://help.sap.com/saphelp_nw04s/helpdata/en/9b/f695f0c84acf46a4e0b31f69d8a9b7/frameset.htm, probably in the studio you cannot browse through tables not in the java dictionary,but manually editing it may still solve the problem.
Also here is another link that specifies the databases supported by J2EE Engine.
http://help.sap.com/saphelp_nw04s/helpdata/en/66/a5283eeb47b40be10000000a114084/frameset.htm

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.
NikolaHi 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.

CMP Entity Bean with ejb-ql finder methods and INFORMIX database
Hi,
I have some CMP Entity Beans with finder methods defined in ejb-ql. In my ejb-jar, within <entity> definitions I have something like:
<entity>
<abstract-schema-name>BeanName</abstract-schema-name>
<cmp-field><field-name>fieldOne</field-name></cmp-field>
<cmp-field><field-name>fieldTwo</field-name></cmp-field>
<query>
<query-method>
<method-name>findAll</method-name>
<method-params></method-params>
</query-method>
<ejb-ql>SELECT OBJECT(o) FROM BeanName o</ejb-ql>
</query>
<entity>
And in persistent.xml:
<db-properties>
<data-source-name>datasource_name</data-source-name>
</db-properties>
<entity-bean>
<ejb-name>BeanName</ejb-name>
<table-name>table_name</table-name>
<field-map key-type="NoKey">
<field-name>fieldOne</field-name>
<column><column-name>column_one</column-name></column>
</field-map>
<field-map key-type="NoKey">
<field-name>fieldTwo</field-name>
<column><column-name>column_two</column-name></column>
</field-map>
<finder-descriptor>
<method-name>findAll</method-name>
<method-params/>
</finder-descriptor>
Once deployed, on server side, I can found a java source file (with corresponding compiled class file) in path:
j2ee/cluster/server0/apps/companyName/MyEARApp/EJBContainer/temp/temp38837373733/route/to/package/
with names:
BeanName0_0pm.java
BeanName0_0PM.class
and the generated java file contains this code:
public java.util.Enumeration ejbFindAll() throws javax.ejb.FinderException, javax.ejb.EJBException {
TransactionContext tc = pm.getTransactionContext();
Connection conn = null;
PreparedStatement pSt = null;
ResultSet ejb_rs = null;
int status = javax.transaction.xa.XAResource.TMSUCCESS;
try {
conn = pm.getConnectionForFindMethod();
pSt = conn.prepareStatement("SELECT \"O\".\"COLUMN_ONE\",\"O\".\"COLUMN_TWO\", FROM \"TABLE_NAME\" \"O\"");
ejb_rs = pSt.executeQuery();
I'm trying to call this method but it throws a SQLException when preparing the statement.
It seems that Informix does not like this SQL syntax because of upper case names, doble quotes on table alias, or something else.
When editing persistent.xml in netweaver, I can define the element <datasource-vendor> as ORACLE, SAPDB, MS_SQL_SERVER, DB2_UDB_AS400 or DB2_UDB_OS390 but INFORMIX is not an accepted value.
Is there any way to define how this SQL query is build?
Thanks in advance.The return type of the finder method defined in the remote home interface is either the entity bean's remote interface or a collection of objects implementing the entity bean's remote interface. The return type of the finder method defined in the local home interface is either the entity bean's local interface or a collection of objects implementing the entity bean's local interface

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

CMP Entity Bean With Primary Key of int
Is it valid to have a CMP Entity Bean (v1.1) where the primary key is defined as the primitive 'int' instead of a true Java class?
Thanks in advance,
MarcHi,
Ur primary key in the EJB cant be a primitive data type. If the primary key in the table is a int,

Can Entity Bean with Home Business Method replace Stateless Session Bean?
Since Entity Bean can have business methods in the Home Interface, can we use Entity Bean with Home Business Methods to replace Stateless Session Bean?
I am assuming we can get better performance by doing this since the overhead of creating Component Object can be avoided as compared to stateless session beans.Requires-new makes the container start a new transaction. Only use that flag
at the point that you are certain that a NEW transaction should BEGIN. I
suggest you use Required as your default for all methods in the application,
and only change that to anything else when you are certain that you should.
Peace,

Do I need to Create Primary Key Class for Entity beans with Local interface
Do I need to Create Primary Key Class for Entity beans with Local interface?
I have created my entity bean with the wizard in Sun One Studio and it does not create a primary key class for you.
I thought that the primary key class was required. My key is made up of only one field.
Anyone know the answer.
Jimu dont need to create a primary key class for a entity bean.if ur table's primary key feild(int ,float) is a built in or primitive data type,then u dont need one.But if ur table has a primary key field which is non primitive (for example StudentID,ItemID etc)then u have to create a primary key class.
hope this helps :-) -
Multiple users accessing entity bean with same PK
Hi,
Some body please clarify the below issue.
(EJB 1.1, WAS3.5)
I have two app servers and two clones each clone is running in each app server.
Stateful session bean access Entity beans to update/read record in the database.
According to my requirement multiple users can access the same entity data (same primary key). Suppose user A created a Stateful session bean SB1 and the SB1 created Entity1 with PK1, this is happening at clone1.
User B accessed the site and the request went to Clone2 and a new SB2 created, but the SB2 need to access the database with Same PK1.
For the above situation, I guess container can not create a new Entity bean with PK1 because EB with PK1 is already there and it tries to allocate same EB1 with SB2, so if two requests are concurrent do the SB2 wait to get the handle of the EB1?
Is there any way to create two Entity beans with same Primary Key at the same time but in different clone?
Thanks,
SagarHi,
The concurrency level has to be set at the level of database and the database will take care of consistency & integrity of the data. So specity the concurrency level on the database connection in each appserver. -
Creating entity beans with auto numbered primary key
I have two entity bean with a CMR between them. I am successfully creating the first one but when I try and create the child entity bean I get a NullPointerException.
Now I think this is because the gernerated code tries to get the primary key of the created entity bean and this is not set as it is set using a auto number in the database (An oracle sequence and trigger).
Is there anyway i can get round this problem?
Thanks in advance,
AdrianThis is the auto generated code:
public dmd.sync.ejbs.entity.AppliancePackInfoLocal create_Local(dmd.sync.dataobjects.dto.AppliancePackInfoDTO appliancePackInfoDTO, dmd.sync.ejbs.entity.AmppLocal amppLocal) throws javax.ejb.CreateException, java.rmi.RemoteException {
BeanO beanO = null;
dmd.sync.ejbs.entity.AppliancePackInfoLocal result = null;
boolean createFailed = false;
boolean preCreateFlag = false;
try {
beanO = super.createBeanO();
dmd.sync.ejbs.entity.AppliancePackInfoBean bean = (dmd.sync.ejbs.entity.AppliancePackInfoBean) beanO.getEnterpriseBean();
preCreateFlag = super.preEjbCreate(beanO);
bean.ejbCreate(appliancePackInfoDTO, amppLocal);
Object ejsKey = keyFromBean(bean);
result = (dmd.sync.ejbs.entity.AppliancePackInfoLocal) super.postCreate_Local(beanO, ejsKey, true);
bean.ejbPostCreate(appliancePackInfoDTO, amppLocal);
super.afterPostCreate(beanO, ejsKey);
It must be falling over on the last line as it calls the ejbPostCreate fine. -
Entity bean with primary key generated by trigger
Hi,
We have a table(oracle) with one column as primary key,
but the primary key is generated by trigger every time
a new row is inserted into this table, inside the trigger,
it uses oracle sequence to get the next val.
If we want to use entity bean with it, what should we specify, it's not application-managed primay key, it's
not auto-generated primary key either. How can we resolve
it without change the database part.
Any thought is appreciated.
Thanks
afangThe code is already there with JDBC call inserting
into the table, the inserting trigger then will generate
sequence key and being inserted into primary key column.
Now wondering if it's possible to change the code to use entity bean but without modifying the trigger (since it contains other business logics). -

ORA-01407 when removing a CMP Entity Bean with WLS 9.1
Hi all !
I hope you can help me to solve this ?:|
I'm migrating my application from WLS 8.1 SP3 to WLS 9.1.
I'm getting now an SQLException when I try to remove a CMP Entity Bean.
The stacktrace is as follows:

Of course, I replaced the table and column names above to be more readable ;-)
The table MY_TABLE has a CMR field called THE_CMR_FIELD. The column is not nullable in the database (by the way, it's an Oracle 9i).
Everything is fine under WLS8.1
I tried two different Oracle JDBC drivers (9.2.0.5 and 10.2.0.1.0), but the result is always the same within WLS9.1.
Any ideas or suggestions (or even questions) are more than welcome!
Thanks

</pre>
In fact I have this setup:
<pre>
workpattern 1..n workpatternday -| 1..n dayperiod
| 1..n daycoreperiod
</pre>
And before 'ejbRemove'ing the workpattern I first remove the days and before that the periods and core periods.
I start with the periods and instead of removing them in the DB he tries to update the FK to the day with '' (p6spy result).
When I remove the not null constraint on the foreign key everything passes to the day where the workpatternId cannot be set to null.
He does not throw errors on the coreperiod (where the not null constraint to day is still present).
When I invert the sequence of deleting
(first the core periods then the 'regular' periods) he complains about the dayId on the core periods table.
So it's completely absurd :S
I hope weblogic 8.1 might solve this problem as this development code is still to be migrated to 8.1 before going in production...
I would just like to know what's wrong. There are other places with just about the same relationships (CMR and DB) where he does not complain...
Maybe you are looking for
