UML model & entity object

would you please tell me what's the
difference between these two environments.

Parisa,
Can you explain more what you mean? In JDeveloper it is possible to create Entity Objects either through using the BC4J Wizards or visually using the UML diagrams. The objects created are the same thing.

Should I start with Entity Object or Java Class Diagram ??

Hi,
I come to J2EE / OO application development from non-oo programming world. I am still confused about what step-by-step development approach should I take ?
Should I :
- start with creating Entity Object from available database table ?
- should I start with Java class diagram, followed by generating database tables, then create EO from it ?
Could anybody please help me, what best practice step by step development approach should I take ?
Is there any white paper / docs about this ?
Thank you for your help,
Krist

Krist,
If you are not from the OO world then you may be interested in this new site on OTN (http://otn.oracle.com/formsdesignerj2ee) There is a workshop that starts by looking at an existing datamodel and builds up from there.
If you are starting from nothing, you can indeed start higher at the Class Model level.
I recently started discussing data modeling on my blog (http://www.groundside.com/blog/content/SueHarper/) and there are some very good comments(feedback from readers) that may possibly be useful to you.
If you are new to the UML modeling world, I recommend you read two very good papers by Jan Kettenis on OTN (http://www.oracle.com/technology/products/jdev/collateral/collateral10g.html) They are Getting Strted with UML Class modeling and Getting Started with UML Use Case Modeling.
Shay pointed you to Toplink. There are a lot of resources on OTN for Toplink, including tutorials.
Personally? I think if you have time, and if you can, start with a Class Model and perhaps a Use Case model, then you can start planning your application development from a solid base.

Error while creating new entity object.

Hi all
I'm using Jdev 11.1.1.3. I want to create an entity object and Jdev issues an information error saying "Either this is not a valid name or an object with that name already exists."
I found that if the package I'm targeting for the new entity is called "com.test.model.whatever" I cannot create a EO called "Whatever".
I can't find any reference in the fusion developer guide that constraints the entity names to be allowed.
Is there a way to circumvent this issue or is this the way it should be?

Sudipto and Suresh, thank you very much for your replies.
I know that changing the package or entity name would work, but was expecting some other kind of workaround, something like giving a full qualified name on some xml or something to avoid the name clash or whatever the problem is.
I do not like packing all the entities together as it goes against my best practice of packing things that change together on the same package. Also I don't like suffix or prefix class names as it goes against my best practice of short descriptive names.
So well, I will have to tinker the names some more and meet you guys half way.
I will now mark this thread as answered, thanks again.

Using JPA Entity-Objects defined in other EJB-Development Component

Hello Community,
I'm working on a Java-Application on NW CE 7.1, using JEE5 Beans in the Business-Logic-Layer and WebDynpro/Java in the UI-Layer.
I designed a Bean for working with data, stored in a database-table of the system-database.
For that addtionally i created a class, representing the Entity-Object, in the same Development-Component of Type EJB 3.0.
It looks like this:
@NamedQueries ({
     @NamedQuery (name="findAllSdCust", query="SELECT c from SdCust c ORDER BY c.kdnr"),
     @NamedQuery (name="findSdCustByKdnr", query="SELECT c from SdCust c WHERE c.kdnr = :kdnr"),
     @NamedQuery (name="findSdCustByIlnnr", query="SELECT c from SdCust c WHERE c.ilnnr = :ilnnr")
@Entity
@Table(name="ZKALL_SD_CUST")
public class SdCust implements Serializable {
     @Id
     @TableGenerator (name="idGenerator", table="ZKALL_ID_GEN", pkColumnName="GEN_KEY", valueColumnName="GEN_VALUE", initialValue=100)
     @GeneratedValue (strategy=GenerationType.TABLE, generator="idGenerator")
     private long id;
     private String name;
     private String lname;
     private String kdnr;
     private String ilnnr;
     private long connid;
     private long cnt;
     @Version
     private long version;
      Constructor, Getter and Setter methods follow here
The corresponding bean looks like this
@Stateless(name="SdCustBean")
public class SdCustBean implements SdCustLocal {
     @PersistenceContext (unitName="xyz")
     private EntityManager em;
     public SdCust getSdCustByKdnr (String kdnr)
          SdCust result = new SdCust();
          // List<Manufacturer> resultList = new ArrayList<Manufacturer>();
          Query myQuery = em.createNamedQuery("findSdCustByKdnr");
          myQuery.setParameter("kdnr", kdnr);
          result = (SdCust) myQuery.getSingleResult();
          return result;
     public void setEM (EntityManager iem)
          em = iem;
       // other methods .....
After that i created a new Development-Component of Enterprise Application-Type and added above DC to this EAR-DC. I also supplied the nessecary descriptor-files/Enries in EJB-DC and EAR-DC.
When now using this bean from WebDynpro with the Web-Dypro EJB-Model-Import everything works fine.
The bean returns the desired object(s).
But now i created a new DC of type EBJ 3.0
This DC contains a Message Driven Bean. That MDB is a Job-Bean which i want to schedule. That Bean uses JRA to connect to an SAP-Abap-System to read some Data and should use JPA to insert/upate/delete the read data in the Database. This should work as a simple replication for my application.
I assigned that EJB-DC containing the MDB to a new EAR-DC together with job-definition-xml and the neccessary entries in deployment-descriptors.
After deploying i see the corresponding job-defition in the NW scheduler using the administrator-views.
I'm also able to schedule the job and it executes fine. Connecting to SAP-Abap System also works fine using JRA.
But JPA does not work!!!!!
I created an dependency from my EAR-DC containing the Job EJB-DC and to the EJB-DC containing the Entity-Class.
I tried three diferent things to get i running, but all of them failed.
1.)
The part looks like:
public class MasterDataReplicateJobBean extends MDBJobImplementation implements MessageListener
@EJB SdCustBean mybean;
   public void onJob(JobContext ctx) throws Exception {
        SdCust sdCust = mybean.getSdCustByKdnr (mykdnr);
Compiles fine. But this fails because the Data is stored in the system-database. The exception says, that i have to use a datasource which supports 2-Phase commit. I know, that i could possibly solve this problem by annotation the Method getSdCustByKdnr with the Annotation for the Transaction-Manager to use REQUIRES_NEW Transaction. But i dont want to generally annotate my methods this way.
2.)
This part looks like this
public class MasterDataReplicateJobBean extends MDBJobImplementation implements MessageListener
@PersistenceContext (unitName="xyz")
private EntityManager em;
   public void onJob(JobContext ctx) throws Exception {
     SdCust cust = new SdCust();
     Query myQuery = em.createQuery("SELECT c from SdCust c WHERE c.kdnr = :kdnr");
     myQuery.setParameter("kdnr", dbkdnr);
     cust = (SdCust) myQuery.getSingleResult();
This also results in a runtime-exception because the entity-Manager cant resolve SdCust from the Query as an Object. The Exception is:
java.lang.IllegalArgumentException: line 1: Abstract Schema Type 'SdCust' doesn't exist
SELECT c from SdCust c WHERE c.kdnr = :kdnr
3.) and last try so far:
public class MasterDataReplicateJobBean extends MDBJobImplementation implements MessageListener
@PersistenceContext (unitName="xyz")
private EntityManager em;
   public void onJob(JobContext ctx) throws Exception {
     SdCustBean custBean = new SdCustBean();
     custBean.setEM(em);
     SdCust cust = custBean.getSdCustByKdnr(kdnr);
In this example i use the Bean from the beginning not as a bean itself but as a normal class. that class has an addtional Method setEM to set the Entity-Manager (which is injected when using the class as a bean)
In that way i got the exception, that the named Query "findSdCustByKdnr" cannot be found by the entity-manager.
It seems to me, that i can access the class, but that all annotations belonging to JPA for that class are not recognized.
Does anybody can give me a hint to solve this problem? Did i forgot something important?
best regards
matthias hayk
Edited by: Matthias Hayk on Feb 5, 2009 9:38 AM

I was already on wright trace.
My class "SdCust" was not recognized by the Entity-Manager as an Entity-Class.
This relies on the storage of the entity-class and where the Entity-Manager looks for entity-classes.
By default it seems to look for all classes in the same jar file. thats the reason why everything works fine when the using bean and the entity-class are in the same project.
In my last case, the using bean is in another development-component and so also in anohter jar file. in this case the entity-manager must be told where to find entity-classes.
this is done in the persistence.xml file.
i added the line
<jar-file>xxx.yyy.com~mdata_beans.jar</jar-file>
underneath the <persistence-unit>-tag.
This works.

Why does R/3 have no ABAP UML modelling tools integrated?

I find it strange that SAP tout the benefits of OO programming and ABAP classes, then completely fail to provide a UML round trip modelling tool integrated into the ABAP workbench.
Doesn't this display a lack of foresight on SAPs behalf? I mean, if you are serious about the use of OO software, shouldn't you be serious about providing the framework such as UML modelling tools to facilitate optimal development?
Currently if I design a solution with ABAP objects, I am using Altova UModel to document the solution, but the lack of integration with the ABAP environment means that I am always struggling to keep the code and model in sync.
does anybody have similar views on this? If views are in accordance, couldn't the SDN community try to lobby SAP to provide such a tool?

Hello Anthony
I document my ABAP-OO developments with Altova UModel, too. A colleague recently showed me that the NetWeaver Developer Studio has UML functionality but for Java developments only (where round-trip engineering is already commonplace).
I assume that the problem with ABAP round-trip engineering is the ABAP dictionary. With Java you have the simple data types and the the class hierarchies of Java. In ABAP we also need the dictionary types.
I would appreciate to have such UML tools for ABAP available, yet I do not expect them to become available in the near future.

Cannot 'Synchronize with database' my entity objects

Hello,
I have successfully created entities in my model using the 'new buisness components from tables' function. But now my database moddel has changed and I would like to synchronize my entities with database to get newest colums, but when right clicking an entity, the 'Synchronize with database' link is greyed and cannot be selected.
I have a database connection configured in my application resources and I can still import new tables in my project.
Do you have any idea of what is happening? This is not the case for all my applications. I can still synchronize in some other ones
Thank you for your help
Stephane

Synchronize with the database will be avaialble for the Entity Object
I think there is a problem with the particular entity that got created when you did the business components out of tables..
This is not the case for all my applications. I can still synchronize in some other onesif this is not happening with any other EO in any other application.. then you can try
recreating the EO from the table..
compare what is the change in between the EO that can synchronize and your current EO that cannot synchronize..
another option might be to check the application.. if that is havign some hidden property to synchronize..
last is to go with sameer's approach, to doubt about the table is not proper... in the same applciation create an EO with another table and try to synchronize.. you will get to actually the point where there is a problem..
good luck.

Synchronize with Database on Entity Object re-creates Association

hi
Please consider this example application created using JDeveloper 11.1.1.4.0
at http://www.consideringred.com/files/oracle/2011/MovedAssociationApp-v0.01.zip
It has an EmpManagerFkAssoc Association which has been moved from the "movedassociationapp.model.entities" package to the "movedassociationapp.model.assoc" package (using the "Refactor - Move..." context-menu option).
When selecting "Synchronize with Database..." in the context-menu of the Employees Entity Object, and clicking the "Synchronize All" button, this results in JDeveloper re-creating the EmpManagerFkAssoc Association,
as shown in the screencast at http://screencast.com/t/l7jaoU2C
- (q1) Is this Association re-creation intended behaviour (if so, please explain, if not, which bug number)?
many thanks
Jan Vervecken

Ferez,
have you seen this thread in the ADF forum, Cannot 'Synchronize with database' my entity objects ?
It mentions the existence of a bug that may cause this (though no reference number), and one user posted a workaround they were using.

ADF: use of view link Accessor in Entity Object = always null?

Hi,
JClient 9.0.5.2, adf model.
I would like to use the view link accessor method in the master EO to retrieve detail EO values and the view link accessor method in the detail EO to retrieve master EO values.
Detail Rule:
In the detail EO an attribute is derived from an attribute of the master EO: detail attribute = master attribute.
Master Rule:
In the master EO an attribute is derived from the detail EO: master atribute set to 0 if detail EO exist else set to 0.
Tables:
Table Master => MasterEO => MasterVO
- masterPK (not updateable)
- masterField (not updateable)
- hasDetailsFlag
Table Detail => DetailEO => DetailVO
- detailPK (not updateable)
- masterPK => foreign key (not updateable)
- masterField (query only)
MasterDetailLink based on foreign key.
In link wizard I asked for the generation of following accessors in the source & destination Entity Objects:
In DetailEO accessor name: RetrieveFromMaster
In MasterEO accessor name: RetrieveFromDetail
In the DetailEO, I asked for the generation of the DetailEOImpl file, accessors and create method.
As wriiten in the file, before the create method:
** Add attribute defaulting logic in this method. **
I tought this is the place to retrieve the master attribute:
The code:
MasterVORowImpl masterVO = getRetrieveFromMaster();
if (masterVO == null)
System.out.println("MasterVORowImpl masterVO create NNNNNNNNNNNUUUUUUUULLLLLLLLLL");
The masterVO is always null?
I suppose I didn't understand something, my guest is that ViewObjects may not be used for default logic?
I know how to implement those rules in the database with triggers.
I think that the data I need for implementing those rules exist somewhere at the ADF level so retrieving the data from the db is not necessary?
Could somebody give some clues?
I didn't find a similar example in the Business Rules in BC4J document.
Your help will be appreciated
Frederic

Hi,
Detail Rule, copy attribute value form master.
In DetailEOImpl:
protected void create(AttributeList attributeList)
setAttribute(MASTERFIELD,this.getMaster().getMasterField());
super.create(attributeList);
Master rule, set flag to 0 if no details else set to 1.
In the MasterEOImpl added method to check if detail row exists based on Row Iterator => no db retrieval?
This method also sets the flag accordingly:
protected void checkHasOtherDetails()
oracle.jbo.RowIterator ri = this.getRetrieveFromdetail();
ri.last();
// last() must be called else hasNext() returns true even on last delete ???
Number hasDetails = Constants.NUMBER_NO; // = 1
if (ri.hasNext() || ri.hasPrevious())
hasDetails = Constants.NUMBER_YES; // = 0
if (!getHasDetailsFlag().equals(hasDetails)) {
this.setHasDetailsFlag(hasDetails);
I call this method in the remove method of the detailEOImpl:
public void remove()
this.getRetrieeFromMaster().checkHasOtherDetails();
super.remove();
To set the flag I added follwoing code in the create method of the DetailEOImpl:
protected void create(AttributeList attributeList)
setAttribute(MASTERFIELD,this.getMaster().getMasterField());
**** ADDED ***
Number masterHasDetailsFlag = getRetrieveFromMaster().getHasDetailsFlag();
if (!masterHasDetailsFlag.equals(Constants.NUMBER_YES)) {
getRetrieveFromMaster().setHasDetailsFlag(Constants.NUMBER_YES));
super.create(attributeList);
One more question:
Is there a danger of calling last() on row iterators in create/update/remove methods of *Impl files?
=> current row changed => any effect on display in JPanel
Thanks
Frederic
PS All variable/method/class names have been manually renamed in this code so some small syntax problems may exist.

Creating Views on multiple entity-objects

Dear Forum,
Is it possible to make associations and lookups based on multiple entity-objects.
I made a custom view, say view1 based on two entity-objects, say entity1 and entity2.
I used some fields from entity1 and some from entity2. There's a 1 to 1 association between the index of entity1 and entity2.
Now I want to make a master-detail between entity1 and view1. I tried to make links and associations, but that didn't work.
Any ideas?
Kind regards,
Arjen

Arjen,
I am a bit confused by what it is you need. It appears you may have Entity Object and View Objects mixed up. Entity Objects are one-to-one with database tables. So, for every table one Entity Object, and the other way around. Associations are, pretty much, one-to-one with foreign keys on the database. So, if two tables have a foreign key between them, the two Entity Objects will have an Association between them. In that respect, Entity Objects and Associations are usually 'strictly defined' by the database model.
The layer of View Objects and View Links is where you 'get design control' in the Business Components arena. A View Object can be based on zero, one or more Entity Objects. Viewlink, defining 'Master-Detail' relationships between View Objects (and NOT Entity Objects!!) can but don't have to be based on Entity Associations (i.e. foreign keys), but can be based on any attribute in the 'Master' view to any attribute in the 'Detail' view.
In this respect, your statement that you want to "make a master-detail between entity1 and view1" makes no sense. It sounds like you need to create a View2, and then make a View Link between View1 and View2.
Kind regards,

Any solutions?
Thnx.

This works ok for me so I don't think its a Jdev 10.1.3 issue - more likely a configuration / version issue.
I'm using MySQL 10.0.15; mysql-connector-java-3.3.11-bin.jar
Below are my configuration notes - I never encountered this error, but thought I would share my config notes to possibly help review a config that is working:
Oracle Jdeveloper Tools | Default Project Properties
1.     Set up MySQL User Library - Configure JDeveloper to work with MySQL Connector/J Download MySQL Connector/J 3.0.11 and copy the JDBC driver JAR file to a known location, such as /jdev/lib From the Tools menu, select Default Project Properties. In the tree view, select Libraries. In the right pane, select New. The Create Library dialog will be displayed. Name the library MySQL JDBC. Set the location to Users Libraries. Click Edit for the Class Path. The Edit Class Path dialog is displayed. Click Add Entry. The Select Path Entry dialog is displayed. Navigate to the JAR file for the MySQL Connect/J JDBC driver (it should be called something like mysql-connector-java- -bin.jar). Click on the .jar file and click Select. Click OK; Under Libraries, ensure MySQL JDBCchecked
2. To use MySQL with BC4J: Add the MySQL JDBC JAR file to <JDeveloper10.1.3>\BC4J\lib directory (note there are some other posts on this topic)
thanks
Tom
PS - also noticed in your message:
com.mysql.jdbc.Ststement
probabley should be 'Statement' - was this something you typed in your config - if so, could possibly be a type-o

Setting permissions at entity object level using JAAS and LDAP

Hi,
I am using ldap-based provider for authorizaton. Every thing works fine. Authorization works fine based on the roles created in web.xml file.
Could you please let me know how I can define permissions at entity object level when using ldap based provider.
Following line is the permission created for an entity object (SpcStrBdgt) when using XML-based provider.
<permission>
<class>oracle.jbo.server.security.jazn.JboJAZNEntityPermission</class> <name>model.SpcStrBdgt/READONLY</name>
</permission>
Above is defined in jazn-data.xml file.How can I define the same thing when using ldap-based provider?

Best practice : Base an Entity object on a table or on PLSQL Package?

Hello,
We are going to build an application based upon services. We'd like to implement the data part of our services with the ADF BC components. Each Service data part is represented as an Application.
There are two ways to define an entity within an application
(1) Directly based upon the database tables
(2) Based upon a PLSQL package, containing insert/update/delete functionality (as described in paragraph 26.4 of the ADF Dev. guide for Forms/4GL Developers)
I can imagine that the last methodology is (from a services standpoint) a cleaner separation between the data and the model layer.
What are the advantages/disadvantages in real life of basing an Entity object on a PLSQL package?
Thanks in advance,
Regards Leon Smiers

Hello Frank,
We are going to use the ADF BC model for both JSF pages and Web Services. So I'd like to hve a reusable BC Model.
You mentioned ADF BC transaction management, when you base the BC model upon PLSQL API's, do I have to define my own transaction management?
Regards Leon

Unable to create Entity objects for tables in TimesTen database using ADF

Hi,
I am not able to create Entity and View objects for tables in TimesTen database using ADF. I have installed TimesTen client on my machine.
I have created a database connection by using connection type as "Generic JDBC" and giving driver class and JDBC URL. I am attaching screen shot of the same.
I am right clicking on Model project and selecting New option after that I am selecting ADF Business components and in it I am selecting Business components from tables and there I am querying for tables.I am getting list of tables and when I am trying to create a Entity object from the table after clicking finish Jdev is closing by itself giving an error.
Can anyone please help me how to create Entity objects for tables using TimesTen as database.I might be missing some jars or the way I am creating connection might be wrong or any plugins required to connect to TimesTen.

What is the actual error being given by Jdev? Are you sure that the JDBC connection is using the TimesTen JDBC driver JAR and not some other JDBC driver or the Generic JDBC/ODBC bridge?
Is ADF even supported with TimesTen?
Chris

Should ADF Entity Object Map to Database Table or View?

We are building a new 3-tier JClient/ADF application. We have mapped most entity objects directly to database tables. Now that we are preparing to deploy, our DBA is angry; he believes that all entity objects should be mapped to database views. The developers see this as a headache, UML can not forward/reverse changes, and now we have another layer of abstraction, which doesn't seem to serve a useful purpose. What is the best practice in a new 3-tier application?

Hi,
I'm still having problems but I found out why these tables are returning errors. The username I've been given by the DBA to connect to the database is CONSULTA, but this user is only for querying purposes, the actual objects reside on a differente schema, of course, which is PROD. So the line:
"CONSULTA"."ESTADOS"@"PROD@AYADEV_LOCATION" "ESTADOS"
raises an exception because the table ESTADOS is not located on that schema, but on PROD. If I query the table from SQL Plus with:
SELECT *
FROM [email protected]@AYADEV_LOCATION
then there's no problem at all.
Why is this? How do I instruct OWB to point to the correct schema or to avoind fully qualifying the table name?
Please help me, I'm kind of confused here.
Best Regards,

HOWTO: Expose Entity Object Methods to Clients

By design, clients cannot directly access entity objects. The view object layer provides an extra layer of security--you can choose exactly what data and methods you want clients to see.
This HOWTO describes the process of exposing an entity object method to client programs.
First, if you don't already have one, you must base a view object on your entity object and add the view object to your data model. For full details of how to do this, see the help topics under
+Developing Business Components
--Working with View Objects, View Links, Application Modules, and Clients
+----Creating and Modifying View Objects, View Links, Application Modules, and Clients
For the purposes of this HOWTO, we'll assume that you already have an entity object, Employees, with a method on it, calculateBonus(),
and a view object EmployeesView based on Employees.
First, you must generate a view row class. A view row represents one row of the view object's cache; it corresponds to a view of a particular entity object.
To generate a view row class:
1. Right-click EmployeesView and choose Edit.
2. In the View Object Editor, select the Java page.
3. Select Generate Java File and Generate Accessors for the view row class.
4. Click Done. This creates a class called EmployeesViewRowImpl.
Next, you should add a "delegator" method to the view row class--a public method with the exact same signature as the entity method, that simply calls the entity method. For example:
public int calculateBonus(int rating) {
return getEmployees().calculateBonus(rating);
Next, you should export this method.
1. Right-click EmployeesView and choose Edit.
2. In the View Object Editor, select the Client Row Methods page.
3. Shuttle the method you just created into the Selected list and click Done.
This creates an interface called EmployeesViewRow that contains your method.
Now you can call the method from your client. You should cast the row returned by EmployeesView.current(), the <jbo:Row> tag, or a similar method or data tag to EmployeesViewRow.
For example,
<jbo:Row id="myRow" datasource="ds" action=Current>
<% out.println(((EmployeesViewRow) myRow).calculateBonus(3)); %>
</jbo:Row>
null

Hi Lisa,
There's a difference between exporting methods (on an application module, view object, and view row--this is done on the "Client Methods" tab of the view object and application module wizards and the "Client Row Methods" tab of the view object wizard) and making an application module remotable (which is done on the "remote" tab of the application module wizard).
You should always export methods you want clients to use--and you only need to do this on the application module if you've written methods on your application module (which I didn't in this HOWTO). You can still use these methods in local mode--the interfaces will be present locally. The advantage of exporting methods is that it doesn't lock you into local mode--you'll be able to change to remote mode later (if you decide that's the way to go) with minimal changes--because the interfaces will be present locally even when the implementation classes aren't.
By contrast, you should only make an application module remotable if you're planning on deploying in a non-local configuration. You can do this step right before deployment.
Hope this helps,
Avrom
