Java.io.NotSerializableException - while retriving "one to many" objects
i am getting java.rmi.MarshalException java.io.NotSerializableException
while i try to retrive one to many objects
i have recently migrated from kodo 2.5.x to kodo 3.0.1, and i have parent
object reference in child objects (reverse mapping reference according to
kodo 2.5.x) as shown below
public class BankStatementEntry implements BankStatement {
private Set accountSummary = new HashSet();
public interface BankStatement extends Serializable {
* Returns the accountSummary.
* @return Map
public Set getAccountSummary();
* Returns the accountSummary.
* @return Map
public void setAccountSummary(Set accountSummary);
public class AccountSummaryRecord implements AccountSummary {
private BankStatementEntry bankStatementEntry;
public interface AccountSummary extends Serializable {
* Returns the transactionDetails.
* @return Collection
public Set getTransactionDetails();
the problem is, when i try to retrive BankStatementEntry object, i have to
iterate through each child (AccountSummaryRecord) object and manualy
remove parent object reference (BankStatementEntry) by setting null.
Otherwise EJB throws java.io.NotSerializableException
Is this bug ?
Thanks
karup.

Help with multi-table mapping for one-to-many object inheritance
Hi,
I have posted on here before regarding this (Toplink mapping for one-to-many object inheritance but I am still having problems mapping my object model to my schema.
Object model
The Person and Organisation objects contain base information and have the primary keys person_id and organisation_id. It is important that there is no duplication of person and organisation records, no matter how many times they are saved in different roles.
There are two types of licenceholder in the problem domain, and the ILicenceHolder interface defines information and methods that are common to both. The PersonalLicenceHolder object represents one of these types of licenceholder, and is always a person, so this class extends Person and implements ILicenceHolder.
The additional information and methods that are required by the second type of licenceholder are defined in the interface IPremisesLicenceHolder, which extends ILicenceHolder. Premises licence holders can either be people or organisations, so I have two objects to represent these - PremisesLicenceHolderPerson which implements IPremisesLicenceHolder and extends Person, and PremisesLicenceHolderOrganisation which implements IPremisesLicenceHolder and extends Organisation.
The model is further complicated by the fact that any single Person may be both a PersonalLicenceHolder and a PremisesLicenceHolderPerson, and may be so several times over. In this case, the same basic Person information needs to be linked to several different sets of licenceholder information. In the same way, any single Organisation may be a PremisesLicenceHolderOrganisation several times over.
Sorry this is complicated!
Schema
I have Person and Organisation tables containing the basic information with the primary keys person_id and organisation_id.
I have tried to follow Donald Smith's advice and have created a Role table to record the specialised information for the different types of licence holder. I want the foreign keys in this table to be licenceholder_id and licence_id. Licenceholder_id will reference either organisation_id or person_id, and licence_id will reference the primary key of the Licence table to link the licenceholder to the licence. Because I am struggling with the mapping, I have changed licenceholder_id to person_id in an attempt to get it working with the Person object before I try the Organisation.
Then, when a new licenceholder is added, if the person/organisation is already in the database, a new record is created in the Role table linking the existing person/organisation to the existing licence rather than duplicating the person/organisation information.
Mapping
I am trying to use the toplink mapping workbench to map my PremisesLicenceHolderPerson object to my schema. I have mapped all inherited attributes to superclass (Person). The primary table that the attributes are mapped to is Person, and I have used the multi-table info tab to add Roles as an additional table and map the remaining attributes to that.
I have created the references PERSON_ROLES which maps person.person_id to roles.person_id, ROLES_PERSON which maps roles.person_id to person.person_id and ROLES_LICENCE which maps roles.licence_id to licence.licence_id.
I think I have put in all the relationships, but I cannot get rid of the error message "The following primary key fields are unmapped: PERSON_ID".
Please can somebody tell me how to map this properly?
Thank you.I'm not positive about your mappings, but it looks like the Person object should really have a 1:M or M:M mapping to the Licenceholder table. This then means that your object model should be similar, in that Person object could have many Licenses, instead of being LicenceHolders. From the looks of it, you have it set up from the LicenceHolder perspective. What could be done instead if a LicenceHolder could have a 1:1 reference to a person data object, rather than actually be a Person. This would allow the person data to be easily shared among licences.
LicenceHolder1 has an entry in the LicenceHolder table and Person table. LicenceHolder2 also has entries in these tables, but uses the same entry in the Person table- essentially it is the same person/person_ID. If both are new objects, TopLink would try to insert the same person object into the Person table twice. I'm not sure how you have gotten around or are planning to get around this problem.
Since you are using inheritance, it means that LicenceHolder needs a writable mapping to the person.person_id field- most commonly done through a direct to field mapping. From the description, it looks like roles.person_id is a foreign key in the multiple table mapping, meaning it would be set based on the value in the person.person_id field, but the person.person_id isn't actually mapped in the object. Check to make sure that the ID attribute LicenceHolder is inheriting from person hasn't been remapped in the LicenceHolder descriptor to a different field.
Best Regards,

Toplink mapping for one-to-many object inheritance
Hi
I currently have a Person object, extended by two specialist classes, PremisesLicenceHolder and PersonalLicenceHolder. I have mapped this in Toplink and it works fine saving a person into the specialist tables using the primary key person_id.
However, a single Person may be extended any number of times by either one or both of the two specialist types. So, a Person may be a PremisesLicenceHolder many times over for different premises and licences, and also a PersonalLicenceHolder several times over.
Is it possible to map this object model in Toplink avoiding duplicate person_id primary keys in the specialist tables?
ThanksHi,
I am happy that my object model fits the problem domain. The Person and Organisation objects contain base information and have the primary keys person_id and organisation_id. It is important that there is no duplication of person and organisation records, no matter how many times they are saved in different roles.
There are two types of licenceholder in the problem domain, and the ILicenceHolder interface defines information and methods that are common to both. The PersonalLicenceHolder object represents one of these types of licenceholder, and is always a person, so this class extends Person and implements ILicenceHolder.
The additional information and methods that are required by the second type of licenceholder are defined in the interface IPremisesLicenceHolder, which extends ILicenceHolder. Premises licence holders can either be people or organisations, so I have two objects to represent these - PremisesLicenceHolderPerson which implements IPremisesLicenceHolder and extends Person, and PremisesLicenceHolderOrganisation which implements IPremisesLicenceHolder and extends Organisation.
The model is further complicated by the fact that any single Person may be both a PersonalLicenceHolder and a PremisesLicenceHolderPerson, and may be so several times over. In this case, the same basic Person information needs to be linked to several different sets of licenceholder information. In the same way, any single Organisation may be a PremisesLicenceHolderOrganisation several times over.
Sorry this is complicated!
My initial idea for the schemas is to have Person and Organisation tables containing the basic information with the primary keys person_id and organisation_id. The Person table would have a one-to-many relationship with both the PersonalLicenceHolder table (pk: personalLicenceHolder_id, fk: person_id), and the PremisesLicenceHolderPerson table (pk: premisesLicenceHolderPerson_id, fk: person_id). There would also be a one-to-many relationship between the Organisation table and the PremisesLicenceHolderOrganisation table (pk: premisesLicenceHolderOrganisation_id, fk: organisation_id).
I am flexible as to the design of my schema though, as I am happy to adopt any that will facilitate the Toplink Mapping.
Thanks for your help with this. -

One to many relationship in hibernate

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
session.persist(order);
session.getTransaction().commit();
session.close();
I can see Order and Order Line are get persisted but Order Line table don't have order_id populated automatically. Please help me out.That is because you're not setting it, obviously. Nowhere in your code are you actually populating the order property of the orderlines.

Hi,all
I have two tables:
CREATE TABLE UserInfoTable (
loginId VARCHAR(32) CONSTRAINT pk_userLoginId
PRIMARY KEY,
regionId NUMBER(12),
accountId NUMBER(12) NOT NULL)
CREATE TABLE AccountTable
accountId NUMBER(12) NOT NULL PRIMARY KEY)
i have established the two master tables on the master site,but
when i create snapshot as:
CREATE SNAPSHOT test.AccountTable ON PREBUILT TABLE
REFRESH FORCE
START WITH to_date('20/12/2001 07:39:49 am','dd-Mon-yyyy
HH:MI:SS am')
NEXT /*1:Hr*/ sysdate + 1/(30*24)
FOR UPDATE
AS select * from [email protected] A where
exists (select 1 from [email protected] B
where A.accountId = B.accountId and B.regionId = 2)
i got the following error:
ORA-12013:updatable snapshots must be simple enough to do
fast refresh!
i have create snapshot log on userinfotable.accountId and
userinfotable.regionid on master site.but if i get rid of the
above "FOR UPDATE",then it works well.
this subquery is one to many subqueries?
the document of oracle 9i said:
Note: The materialized view site must have a compatibility level
of 9.0.0 or higher because fast refresh of materialized views
with one to many subqueries was not supported prior to release
9.0.0 of Oracle. The compatibility level is controlled by the
COMPATIBLE initialization parameter.
i use Oracle enterprise edition 8.1.7.so it can't do updatable
snapshots while using one to many subqueries?
Anybody can help me?i have wandered on this problem serveral
days.
thanks in advance!.. do you know if there are firewalls that can implement one-to-many nat ? tipically one private ip statically natted to many public ip .. checkpoint, fortigate ..

One to Many Using an Interface
I have a one to many object mapping. There is a foreign key on the many table that is not being auto populated when it gets added to the one object. Is this normal activity? I would think that this column would not have to be explicitly set.
Also, I am using sequencing on the primary key of both the one object and the many object.
Following is a simplified code excert of what I am doing. Could I be doing something wrong?
Thanks,
Michael
public void testAddManyObject(OneObject oneObject){
UnitOfWork uow = this.getUnitOfWork();
ManyObject manyObject = new ManyObject();
uow.assignSequenceNumber(manyObject);
payoff.setRandomValue("10000");
oneObject.addManyObject(manyObject);
uow.registerObject(payoff);
uow.commit();
}(I am assuming that "payoff" is your "oneObject", otherwise I'm not sure of it's relevance in the example).
Does your addMany(Many aMany) look like this:
public void addMany(Many aMany) {
manyCollection.add(aMany);
aMany.setOne(this);
In other words, it's the 1-1 back reference that's really important in a 1-M... You shouldn't have to force the assignment of sequence numbers unless you want it for your business domain for some reason.

Urgent : java bean having bidirectional one to many relationship
Hi,
We have complex requirement in our application.
We need to copy java bean having bidirectional one to many relationship to another javabean having bidirectional one to many relationship..
E.g
Class Basket1 {
public String color;
pubic String type;
public List<Basket1> basketList = new ArrayList()
Class Basket2 {
public String color;
pubic String type;
public List<Basket2> basketList = new ArrayList()
We need to exact copy Basket1 to Basket2. We are in trouble to copy List of child because we do not have how many child Basket1 have of same type..
Can someone help us how we can implement such kind of complex object bidirectional one to many relationship??I can't see anything bidirectional about these relationships. What I can see is a couple of BasketN classes that look identical so I don't know why they both exist, and they both contain lists of themselves as members, which suggests some kind of tree structure. Nothing bidirectional there. I can see tat these things can form circular object graphs but I don't see why you would want to do that.
We need to exact copy Basket1 to Basket2And I don't know what that means. Please explain. -

Java.io.NotSerializableException
I am running iplanet ias 6.0 sp3 with web server 6.0 sp1. I
successfully deployed an ear file that contains the war and the jar to
the APPS dir. The session ejbs and the entity ejbs are packed into the
jar file which are deployed with the ear.
I have two piece of testing code. One is a standalone java program.
The other one is a jsp page together with the jsp bean which are packed
into the war file in the ear. The jsp bean code and the standalone
program are doing the same thing. They call a session ejb which calls an
entity bean.
I have made 2 experiments
1> Start server, run the standalone test, got the correct result.
Then run the jsp from the browser, got the correct result.
2> Start server, run the jsp from the browser, fail to get the
result. run the standalone test, fail to get the result
The paten is very consistent. The code and the error msg for test 2 are
attached. Could any one tell me what might cause the problem in the
second test and how to resolve the it ?
Thank in advance

When the test fails, I got the following error msg from the console.

}Xiao,
We have the same problem.
The reason why your stand alone works, but your browser based doesn't,
is because the iPlanet Application server requires that all EJBs, all
objects held in any EJB, all objects held in attributes in an
HttpSession, and all objects held in those objects MUST implement
java.io.Serializable.
The unfortunate reason why iPlanet does this is because iPlanet does not
preserve the state of objects in memory across hits to the server.
iPlanet serializes each and every object mentioned above when the HTML
is returned to the client, and then un-serializes all the objects again
when it receives another hit from the client. This is true even in the
case of no-dsync sticky load balancing.
This is ridiculous. We use sticky load balancing and we have many
objects stored in HttpSession attributes which we do not want to be
serialized every hit to the server, in the interest of speed. It takes
too long to serialize all the objects, and it would take way too long to
save them in a database every hit.

I am running iplanet ias 6.0 sp3 with web server 6.0 sp1. I
successfully deployed an ear file that contains the war and the jar to
the APPS dir. The session ejbs and the entity ejbs are packed into the
jar file which are deployed with the ear.
I have two piece of testing code. One is a standalone java program.
The other one is a jsp page together with the jsp bean which are packed
into the war file in the ear. The jsp bean code and the standalone
program are doing the same thing. They call a session ejb which calls an
entity bean.
I have made 2 experiments
1> Start server, run the standalone test, got the correct result.
Then run the jsp from the browser, got the correct result.
2> Start server, run the jsp from the browser, fail to get the
result. run the standalone test, fail to get the result
The paten is very consistent. The code and the error msg for test 2 are
attached. Could any one tell me what might cause the problem in the
second test and how to resolve the it ?
Thank in advance
Xiao
When the test fails, I got the following error msg from the console.

Debug level Hibernate log excerpt:
Included in the above description.That's not the right mapping for the 1:m relationship in Hibernate.
First of all, I believe the recommendation is to have a separate .hbm.xml file for each class, so you should have one for Parent and Child.
Second, you'll find the proper syntax for a one-to-many relationship here:
http://www.hibernate.org/hib_docs/v3/reference/en/html/tutorial.html#tutorial-associations
See if those help.
The tutorial docs for Hibernate are quite good. I'd recommend going through them carefully.

Java.io.NotSerializableException when using POF over Extend
I changed a class to use POF and it seems to work fine among TCMP cluster members but when apps connect with Extend I get an exception indicating that maybe either the extend proxy or client app is not correctly configured to use POF.

Thanks,
AndrewLooks like I spoke too soon. Moving the <serializer> to the correct location in the Extend client XML config did fix the problem I was seeing but it created a new problem. It appears the Extend client wants to use POF for everything including non-POF services like the one handling the Serializable (non-POF) object oms.Order. That's what I gather from this exception

Weblogic-cmp-rdbms-jar.xml for One-To-Many unidirectional relationship
hi,
I am trying to create a simple cmp One-To-Many unidirectional relationship and deploy the same in weblogic. Can someone help me with the weblogic-cmp-rdbms-jar.xml. Am attaching the weblogic-cmp-rdbms-jar. xml tht i am using as also the corresponding ejb-jar.xml. Pls. note tht i want a unidirectional relationship here. one i am tryng However i get this error:
Error while reading 'META-INF/weblogic-cmp-rdbms-jar.xml'. The error was: Role 'Supplier supplies Products' of relationship 'Product Supplier' contains an invalid key-column value of 'productID'. The key-column must specify a primary key column in the related bean. However, there is no primary key column named 'productID' defined in the related bean 'ProductEJB' or else 'productID' is not being recognized due to case mismatch. My weblogic-cmp-rdbms-jar

</ejb-jar>I think u r some confusion with productID and SuppliedID . primary key of one column( productId ) can be a foreign key of other table colum( SuppliedID). but foreign key( SuppliedID) can not be a primary key of second table .u declared SuppliedId as primary key . so ur mapping is incorrect.

Getting java.io.NotSerializableException: sun.management.MemoryPoolImpl
Hi,
While trying to get JVM Memory pool information of a remote computer ,am getting java.io.NotSerializableException. I used following method
ManagementFactory.getMemoryPollMXBean().
Please help me to solve these exception.

Thanks,
SreejithI agree, it looks frustrating. Obviously the serialization process has found the non-serializable object during the traversal of the object graph, but its difficult to know where this is.
Your class looks a bit "serialization-heavy", if you don't mind me saying. I avoid serializing anything to do with swing components and stick to collections and my own classes. Do you need to serialize these? If not, mark them transient. You can do this for all of them and then reintroduce into the serialized form one at a time to see which one causes the problem (just for curiosity).
When the object is deserialized you will have to make the necessary arrangements to set up any members that you marked transient, as these will be null. You can do this is readObject, but on this subject, why are you writing out the points member explicitly? It will be written out anyway since there is nothing special about it.
I don't know how familiar you are with the serialization package but its a sharp instrument that needs respect. I would advise reading the specification, if you haven't already done so. -
One to many mappings and combination generation
Please help folks,
I want to perform one to many mapping i.e a single row of data will be taken from a single table Table 'A' into Hashtable A and it has to be matched with 'n' number of rows from another table Table 'B' taken into Hashtable B. The no. of rows selected from B can be 1/2.... upto n. For performing this mapping iam using a Combination Generator Code which will Key nos. to be selected for checking whether they can be mapped and then further processing is done on these key nos. returned by the combination generator. The code for combination generator is given below.
The issue is say if there are about 50 rows in table B then no of combinations possible are 2 ^ 50, which is just too much for the PC to handle i.e the code takes about 4-5 days of processing time. 256 MB RAM, P4. The mapping has to be done in 30 minutes!!!! Ne ideas folks????
