Problem with a 1:M relationship between two entity beans

I am having trouble trying to implement a 1:M relationship between two EJB2.0 entity beans using and EJBQL query. I have an ApplicantEJB, which contains a collection of phone numbers. The applicant table in the database has one primary key, applicant_id. The applicant_phones database table has a compound primary key--applicant_id and phone_type_id--so I have implemented a custom PK class to represent this, PhonePK. I have implemented a findByNameAndPhone method in my ejb-jar.xml file with the following syntax:
SELECT object(a) FROM applicants a, applicant_phones p where a.applicantID = p.applicantID and a.name = ?1 and p.phoneNumber = ?2
If I deploy this, Orion/OC4J translates the query in the orion-ejb-jar.xml with an incorrect reference to the applicant_phones.applicant_id column:
SELECT a.applicant_id FROM applicants a , applicant_phones p WHERE ((a.applicant_id = p.applicantID ) AND (a.name = ?) AND (p.phone_number = ? ))
I must have something wrong with the ApplicantEJB and PhoneEJB primary key mappings in my orion-ejb-jar.xml file, but I have tried many different combinations of values and keep getting them overwritten by the container with each deployment. Why is Orion/OC4J defaulting the applicant_id reference to the ob[i]Long postings are being truncated to ~1 kB at this time.

I have posted excerpts from my orion-ejb-jar.xml file in this posting: Problem mapping a 1:M relationship between two entity EJBs w/ a compound PK
Sorry for the duplicate postings, but I was getting errors on the submission.

Problem with 1-to-many relationship between entity beans

Hi All!
I have two tables TMP_GROUP and TMP_EMPLOYEE with following fields:
TMP_GROUP: ID, CAPTION, COMMENT, STATUS.
TMP_EMPLOYEE: ID, LOGIN, GROUP_ID.
For this tables i create two entity beans GROUP and EMPLOYEE respectively.
The relationship looks like this
descriptor ejb.xml:
<ejb-relation>
            <description>description</description>
            <ejb-relation-name>employeesOfGroup</ejb-relation-name>
            <ejb-relationship-role>
                <ejb-relationship-role-name>com.mypackage.GroupBean</ejb-relationship-role-name>
                <multiplicity>One</multiplicity>
                <relationship-role-source>
                    <ejb-name>GroupBean</ejb-name>

                    <cmr-field-name>employees</cmr-field-name>
                    <cmr-field-type>java.util.Collection</cmr-field-type>
                </cmr-field>
            </ejb-relationship-role>
            <ejb-relationship-role>
                <ejb-relationship-role-name>com.mypackage.EmployeeBean</ejb-relationship-role-name>
                <multiplicity>Many</multiplicity>
                <relationship-role-source>
                    <ejb-name>EmployeeBean</ejb-name>
                </relationship-role-source>
            </ejb-relationship-role>
        </ejb-relation>
descriptor persistent.xml:
<table-relation>
               <table-relationship-role
                    key-type="PrimaryKey">
                    <ejb-name>GroupBean</ejb-name>
                    <cmr-field>employees</cmr-field>
               </table-relationship-role>
               <table-relationship-role
                    key-type="NoKey">
                    <ejb-name>EmployeeBean</ejb-name>
                    <fk-column>
                         <column-name>GROUP_ID</column-name>
                         <pk-field-name>ejb_pk</pk-field-name>
                    </fk-column>
               </table-relationship-role>
          </table-relation>
Now i implement business method:
public Long addEmployee(String login, long groupId) {
          Long result;
          try {
               EmployeeLocal employee = employeeHome.create(login);
               GroupLocal group =
                    groupHome.findByPrimaryKey(new Long(groupId));
               Collection employees = group.getEmployees();
               employees.add(employee);
               result = (Long) employee.getPrimaryKey();
          } catch (CreateException ex) {
               result = new Long(0);
          } catch (FinderException ex) {
               result = new Long(0);
          return result;
When i call this method from web service, the following exception is raised:
com.sap.engine.services.ejb.exceptions.BaseTransactionRolledbackLocalException: Exception in method com.mypackage.GroupLocalHomeImpl0.findByPrimaryKey(java.lang.Object).
P.S.
1) I have transaction attribute set to "Required" for all methods of all beans
2) I have unique index for each table:
TMP_GROUP_I1: CAPTION
TMP_EMPLOYEE_I1: LOGIN (however i think GROUP_ID must be added here too)
3) I tried many:many relationship with this tables and it works fine
4) I try another implementation of addEmployee method with
EmployeeLocal employee = employeeHome.create(login, groupId);
without using GroupLocal cmr-field and GroupLocalHome findByPrimaryKey method, the result is same error.
Can somebody help me with this problem?
Thanks in advance.
Best regards, Abramov Andrey.

1: The @JoinColumn on the listOfDepartments collection in Company is wrong. It should be something like this for a bidirectional relationship:
@OneToMany(mappedBy="company") // company is the matching property name in Department
private List <Department> listOfDepartment = new ArrayList<Department>();Note that I removed the fetch configuration; onetomany is fetched lazy by design. Saves some clutter eh.
2: use a Set in stead of a List (hibernate doesn't like lists much in entities and will break when you create slightly more complex entity relations)
3: don't just slap cascades on collections, especially of type ALL. Do it with care. In the many years I've been using JPA I've only had to cascade deletes in very specific situations, maybe once or twice. I never needed any of the other cascade types, they just invite sloppy code if you ask me. When working with persistence you should apply a little precision.I made all changes as you mentioned but still compID in department table shows null value...

Problems with materialized view and fk between two db

Hi,
i have two databases db1 and db2 and from db1 is a table(DM_MESSDATEN) which contains a foreign key to a table(DM_FAUNA) in db2.
Now I want to write my done steps to get more clearification and hopefully someone can point out my wrong steps.
1st
i create the tables inside db1 without a foreign key to the table in db2.
2nd
i create a database link inside db1 to db2
create public database link DATENBANK2 connect to phantomas identified by bachelor06 using 'DMDB2';
3rd
now and here i stuck want to create a materialized view inside db1
create materialized view DATAMART_MVW AS
select * from DM_MESSDATEN, DM_FAUNA@DATENBANK2
where DM_MESSDATEN.FAUNA_ID=DM_FAUNA.FAUNA_ID;
or should the view be created inside of db2?
4th
and then i want to reactivate the foreign key inside the table of db1- but can't because of
problems in step 3 :(
So it would be nice if someone could help me
thanks a lot
thomas

I think you haven't been clear in your statement of your problem:
now and here i stuck want to create a materialized view inside db1Why are you stuck? If you want to enforce a froeign key locally using data from a remote database then you need to build a materialized view on your local table tablespace that sucks data across from the remote database. You can then create a foreign key on your local table using the local MV.
If the remote table is updated frequently and you want the local MV kept in sync then you will need to put soem further replication in place. For instance you may need to create a materilaized view log on the remote database.

Additional data on relationship between two objects

Hi
We have a requirement to capture additional data on a relationship between two objects. The data to be captured are custom fields that are unique to the relationship between the objects and not specific to either of the objects.
We created a new object type and related it to the position (S)and the job (C) object. In the customising (Personnel Management/Personnel Development/Basic Settings/Maintain Relationships there is an option to set up Additional Data. There are however several restrictions (e.g. the substructure has to be in T77AD). When you set up an existing substructure (e.g. PAD22) and screen (e.g. 3000), it works really well, however we have not been able to get this to read our own substructure and screen (since there is no customer include on HRP1001 and the 'Additional data' button seems to go to MP100100 to find the screen).
My question is two fold:
a) Is this an allowed customisation (e.g. can we create our own substructure, screen and Query string)? And if so, how does the data get into T77AD (since SAP recommends that data should not be added to this table)? and
b) Is there any documentation on this (thus far I have only received info on how to enhance infotypes which I don't think is relevant???)?
If this can not be maintained is there any other suggestions on how to deal with this scenario?
Any assistance will be appreciated.
Regards
Liezl

Hi everyone
Thanks for everyone who tried to assist us with this. I am happy to report that our in-house guru's have found the answer. So, for anyone who is interested:
In programme MP100100 you have a screen 6000 which is a customer enhancements screen. We set up two in-house function modules for the PBO and PAI with its own screen and added an append structure to PAD31 to add the fields required. In the configuration, we then specified PAD31 as the substructure with screen 6000 and then also specified our own PBO and PAI function modules. The parameters required for screen 6000 is set up within our own customer screens.
Hope this will be helpful to someone - it certainly seemed to open up some doors for us!

How to get relationship between two views in the reports

How to get relationship between two views in the reports, I am doing a deletion program , it is fully relates to views , how to get relationship between them in the reports

Hi,
Please explain your question in detail...what do you want to read ?
If you want to know about the navigation links between the views then you can use APIs like
wdComponentAPI.getComponentInfo().findInWindows("windowName").getViewUsageByID("Name").getNavigationLinks();
Iterate through the navigationLinkInfo from above collection and can read the other properties .
I haven't tried the above , but it should work !!!

How to build "Greater/less or Equal" relationships between two tables?

Hi,
Is there any straightforward approachs to realize the following kind of relationships between two tables?
Table1.process_end_date >= Table2.work_start_date and
Table1.process_end_date <= Table2.work_end_date
BTW, there's no common columns for these two tables to do simple joins (inner, outter...).
Thanks.
Regards,
Qilong

Sure.
Table.SelectRows filters a given table (in this case Table2) based on a function provided as the second argument.
(table2Row) => is the start of our filter function. It defines a function that takes one argument, called table2Row. Each row of Table2 will be passed to this function. If the function returns true, the row will be kept. If the function returns false,
the row will be filtered out.
The right hand side of the => is the filter expression. Because we're adding the custom column to Table1, we can reference a field in the current row of Table1 using square brackets (e.g. [process_end_date]). To reference the fields in the current row
of Table2, we have to index into the table2Row variable passed to our function (e.g. table2Row[work_start_date]).
Hope that helps.

How exchange messages between two user-bean instances?

Hi,
I would like to let several user to log-in my web site (I'm using tomcat) and then let them exchange some messages until they are logged-in. Is there a way using JSF?
I was thinking about implementing a list of messages inside each user-bean. The user should know that other users are logged-in, that could be listed in a table, and click on its name. I would like that the click action create an item in the list valiable of the selected user. Is that possible using JSF? I didn't find any of such kind of communication between two user-bean instances.
Do you have any hints? Is that the right way or is there other possibilities?
Thanks

You could get hold of a map of sessions in the application scope. Make use of HttpSessionListener to add/remove sessions to/from the map.
JSF is just another component based MVC framework on top of JSP/Servlet. Everything which you can do in JSP/Servlet is just still possible. You only need to understand how JSF works under the hood.
