JPA and Postgres

Hi friends!
I am new with EJB 3.0 and I am trying to do my first Entity Bean. I am working with Postgres and GlashFish. I have a class whose name is "Cabin", and my persistence.xml (under META-INF folder) is:
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence">
     <persistence-unit name="titan">
     <class>paquete.Cabin</class>
     <properties>
          <property name="jdbc.driver" value="org.postgresql.Driver"/>
          <property name="jdbc.connection.string" value="jdbc:postgresql://localhost/TitanDB"/>
          <property name="jdbc.user" value="postgres"/>
          <property name="jdbc.password" value="postgres"/>
          <property name="ddl-generation" value="dropandcreate"/>
          <property name="toplink.logging.level" value="FINE"/>
     </properties>
     </persistence-unit>
</persistence>
And in my Session Bean I have the following code:
@PersistenceContext (unitName="titan")
private EntityManager manager;
When I run my application I get the following error:
javax.naming.NameNotFoundException: SimpleBeanJNDI not found

Stored procedure, EJB, JPA, and JavaServer Faces

Hi!
I am currently working on a Web application using EJB, JPA, and JavaServer Faces. A part of the
business logic is already stored in the database as stored procedures, so we need to call those
procedures (instead of named queries) through a EJB and represent the data on the web tier.
Where can I find an extensive tutorial using this technology? There is no such tutorial in the Oracle Learning Library.
Maybe somebody can provide a link and/or example.
Thanks in advance for your help!

JPA and SQL Server 2005's Identity Don't Play Nice

I am hoping someone with a little more senior knowledge of JPASQL Server 2005 can point me in the right direction involving SQL Server 2005.
What I am discovering is JPA and SQL Server 2005 do not playing nice together when you use the IDENTITY capability for
a primary key. Let me explain. "...when using the IDENTITY as the generator type, the value for the identity field MAY NOT be
available BEFORE the entity data is saved in the database because typically it is generated when a record is committed."
My problem is this.
I have two separate entities using another entity, for example a car has a wheel and a truck has a wheel. I can go through the steps
of persisting the car and the wheel with no problem. My problem begins when I try to
find the wheel (by wheel description) for the truck. The query finds the wheel, but does not return the primary key for wheel.
Therefore, using the PK inside a query generates this error:
java.lang.IllegalArgumentException: An instance of a null PK has been incorrectly provided for this find operation. What has been my appraoch to get the entity to commit to the database is to use the following sequence for the Entity Manager.
entityManager.persist(wheel);
entityManager.flush(); I have assumed to this point this action would persist my data because I have been able to retrieve the PK immidately after these steps.
However, multiple actions taking place within the same transaction, appears to render the persist and flush steps useless. My initial thought
is to wrap the wheel creation within a new transaction so when the method/transaction completes, the data would be in the database. This
has not worked.
I hope I have explained this clear for others to follow. I apologize in advance if I have not. Any suggestions are greatly appreciated.

Heterogeneous connection between Oracle and Postgres.

Hi All,
I'm trying to make an heterogeneous connection between Oracle and Postgres since few days but i still having this error : "lost RPC connection".
First of all : I'm using Windows 7, Oracle 10g and PostgreSQL 8.4.
I have done the following operations :
1) Create a System DNS named "PG". (Test connection is OK)
2) Create the file "initPG.ora" in "$ORACLE_HOME/hs/admin" :
# This is a sample agent init file that contains the HS parameters that are
# needed for an ODBC Agent.
# HS init parameters
HS_FDS_CONNECT_INFO = PG
HS_FDS_TRACE_LEVEL = ON
# Environment variables required for the non-Oracle system
#set <envvar>=<value>
3) Configure the file "listener.ora" (in "$ORACLE_HOME/NETWORK/ADMIN") :
SID_LIST_LISTENER =
(SID_LIST =
     (SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
     (SID_DESC =
(SID_NAME = PG)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = hsodbc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(ADDRESS = (PROTOCOL = TCP)(HOST = Cédric-PC)(PORT = 1521))
DEFAULT_SERVICE_LISTENER = (XE)
4) Configure the file "tnsnames.ora" (in "$ORACLE_HOME/NETWORK/ADMIN") :
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Cédric-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
PG =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = tcp)(HOST = Cédric-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = PG)
(HS = OK)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
5) Finally, i create my DB-Link and test it :
CREATE DATABASE LINK "CENTRALE_POSTGRES" CONNECT TO "user_login" IDENTIFIED BY "user_password" USING 'PG';
SELECT * FROM "dual"@CENTRALE_POSTGRES;
I got this error :
ORA-03135 : lost RPC connection.
As you can see, i have activated the trace level (HS_FDS_TRACE_LEVEL = ON), but the directory "$ORACLE_HOME/NETWORK/trace" still empty.
Any ideas ?
Regards

the tnsnames.ora alias PG is wrong - you need to have 2 closing brackets after the SERVICE_NAME so that HS=OK is outside of the CONNECT_DATA like:
PG =
<space>(DESCRIPTION =
<space><space>(ADDRESS = (PROTOCOL = tcp)(HOST = Cédric-PC)(PORT = 1521))
<space><space>(CONNECT_DATA =
<space><space><space>(SERVICE_NAME = PG))
<space><space>(HS = OK)
<space>)
Please be also aware HSODBC up to release 10.2 has been desupported since March 2008 and it was replaced by its follow up product DG4ODBC V11

JPA and CAF BO - are there any editors of the JPA data (like CAF)?

Hello!
As you know SAP invented some layer above JPA and called it CAF. There is a very convenient way to edit data in CAF.
But now I have to create a complex database scheme, also with CAF doesn't allow us to work with objects. So we can't use someObject.getChildren().
So my question is are there any editors of the JPA data (like it is done in CAF)?

Hi Kirill,
at the beginning of our project at the end of 2009, we did a deep analysis of CAF since our architect vehemently suggested to use this framework.
First about the history and purpose of CAF: Initially, CAF was never meant to be a layer above CAF since CAF was invented in the time before EJB 3.0 and JPA standard where writing persistence with EJB 2.x CMP forced the developer to write pages of boiler plate code. This background was approved by SAP.
With upcoming of JPA, CAF ist mostly useless (except for very simply structured data) and prevents you from writing good software.
It is easy just to write @Entity, @Id and @OneToMany (for complex database schemes) and CAF forces you to use an ugly, imperformant database scheme (e.g. CAF uses mapping tables even for 1:n relationships, a clear antipattern!)
The CRUD-services generated with CAF are a pain, too. Usage of pessimistic locking is not up to date for web applications.
With your complex database schemes, you exceed the limit of CAF.
(We decided not to use CAF and did never regret this.)
Concerning your question: There is an "JPA Details" view in NWDS that might help you. It needs JPA Persistence facet on your project to work. Developed by SAP. For JPA beginners, it is a good cheat sheet for JPA annotations and their attributes.
You do not need more since a JPA POJO is easy to code.
Regards,
Rolf

JPA and Database Views

hi ,
How can i represent my DataBase View in JPA , and since each "Entity" should have an "@Id" how can i handle this on my views since some of them does not have a convenient ID field/fields , Thanks

In this situation I created @Id for one of the columns or created @IdClass from all view fields.

Hi,
Try following the JPA tutorials for WebLogic, JPA using EclipseLink or Hibernate will be the same if you stick to the specification. WebLogic 10.3.4.0 ships with a Java EE 6 compliant JPA 2.0 implementation in EclipseLink - you may want to give that a try.
http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebLogic_Web_Tutorial
http://wiki.eclipse.org/EclipseLink/Examples/Distributed
I also have a JBoss 6 tutorial for getting JPA working as well.
BTW, your persistence unit is currently application managed - try switching to container managed - then most of your jar dependencies will go away as everything is already setup for you to do dependency injection via the container.

What are the relation between JPA and Hibernate, JPA and TopLink?

What are the relation between JPA and Hibernate, JPA and TopLink?
Can JPA instead of Hibernate and TopLink?

The Java Persistence API (JPA) is the object relational mapping persistence
standard for Java. Hibernate and TopLink provide an Open source Object-relational mapping framework for Java.
They provide an implementation for the Java Persistence API. In my opinion, both Hibernate and TopLink provide support to JPA
and they can also be regarded as the complementary to JPA.
Let's wait to see other person's opinions.

SUN AS PE 8 and postgres

Hi everybody,
I'd like to know your experiences about using SUN AS PE 8 and postgres. I have read that actual version has problems with this database manager. It's true?
Thanks...

I found another tread that talks about this problem, http://forum.java.sun.com/thread.jsp?forum=136&thread=509737
A workaround for me was to disable privacy control in my firewall, not a viable solution but will do for now. I am interested in hearing about a real solution to this problem.

Ars ther any significant changes to set roles in 11g?When I eval'd 11g, I did not notice any changes in setting my roles. I did notice a significant difference in Java. I cannot remember the JDK version change from 10g to 11g. We ended up settling back to 10g for other reasons.

Error when creating Recordset using CF and Postgres

I'm a complete newbie when it comes to databases and development so go easy on me.
I have created a simple database with a schema (ABC) and 2 tables (_Address, _Member) in Postgres 9.0. I have installed CF 9 in development and am creating a new application using the Construction Kit Vol 1 as my guide. I got to the point where I am to make a Recordset and keep getting an error of:
-1:ERROR: schema "ABC" does not exist
org.postgresql.util.PSQLException: ERROR: schema "ABC" does not exist
...about 20+ lines of at errors follow (can post a screenshot if they would be helpfull)...
From the Database tab I am able to browse my database just fine but I cannot create this recordset in the bindings tab. I also followed the examples in the book and using their database I am able to create a recordset just fine. CF says my data source verifies correctly. I have verified that my password is correct as well as when in the database tab of DW I can test the connection fine. I cannot edit the connecton from there but I get the same error when I try to edit on all of the databases, including the default test databases.
Any suggestions would be greatly appreciated.

Hi Loan,
In your stock transfer Purchase Order has the correct 'Shipping Point' been determined for this item - i.e. the 'Shipping Point' associated with your 0002 Storage Location?
The 'Shipping Point' determination is setup in config in <OVL2>, you can use the 'Loading Group' field in the Material Master (Sales:General Plant) tab to influence the shipping point that is automatically determined for a Material.
Assuming the Shipping Point has been determined correctly for your 0002 SLoc - then in <VL10B> you will have selected this 'Shipping Point' for your delivery creation. I also noticed that in <VL10B> on the Material tab you have the option to specify a SLoc (I'm assuming this is a source SLoc since the help doesn't clearly specify) - try entering this data too and see if you can generate your delivery.
Good luck,
Ravelle

SAP JPA and lazy loading

Dear experts,
I have a WD application with EJB model. I have faced strange JPA exception (I am using SAP JPA implementation).
This is 2 Entities with relationship
@Entity
@Table( schema = "dbo", name = "class")
public class ClassEntity {
private Long id;
        @Id
     @Column(name="id")
     @GeneratedValue(strategy= GenerationType.IDENTITY)
    public Long getId() {
          return id;
     public void setId(Long id) {
          this.id = id;
private Collection<ClassAttributeEntity> classAttributesById;
    @OneToMany(mappedBy = "classByClassId", fetch=FetchType.LAZY)
    public Collection<ClassAttributeEntity> getClassAttributesById() {
        return classAttributesById;
    public void setClassAttributesById(Collection<ClassAttributeEntity> classAttributesById) {
        this.classAttributesById = classAttributesById;
@Entity
@Table( schema = "dbo", name = "class_attribute")
public class ClassAttributeEntity{
private Long id;
        @Id
     @Column(name="id")
     @GeneratedValue(strategy= GenerationType.IDENTITY)
    public Long getId() {
          return id;
     public void setId(Long id) {
          this.id = id;
    private ClassEntity classByClassId;
    @ManyToOne
    @JoinColumn(name = "class_id", referencedColumnName = "id")
    public ClassEntity getClassByClassId() {
        return classByClassId;
    public void setClassByClassId(ClassEntity classByClassId) {
        this.classByClassId = classByClassId;
I want to execute JPQL query
"SELECT c FROM ClassEntity c"
; But I get this exception:
javax.persistence.PersistenceException: The relationship >>classAttributesById<< of entity {test.ClassEntity(id=1686)}cannot be loaded because the entity is detached
I can overcome it using EAGER loading -
@OneToMany(mappedBy = "classByClassId", fetch=FetchType.EAGER)
, but I really dont need ClassAttributes in this situation! I have many thousands of classes and eager loading provides extremly poor perfomance. What can I do with this problem?
Thanks in advance for any advice.

Hi Andrey,
I assume you are getting the exception if you atempt to access "classAttributesById" ouside the transaction, in which you executed the query, i.e. after the persistence context, in which the query has been executed is closed.
You have got to make sure that all entities you need to access are read as long as the persistence context executing the query is still open.
How to address this depends a bit on whether you need to access all related entites or only some.
If you need to access the relationship "classAttributesById" for only some instances of "ClassEntity", you could for example call size() on "classAttributesById" for these selected instances of "ClassEntity" (within the same transaction/persistence context".
If you need to access all related entities, theoretically, fetchType = EAGER would be the right choice. However, as you have observed, SAP JPA can't handle this efficiently at the time beeing. Therefore,
I'd rather suggest that you firstly load all related attributes with a query
"SELECT ca FROM ClassAttributeEntity ca"
and secondly load the "ClassEntity"s
"SELECT c FROM ClassEntity c"
this should execute efficiently.
Sorry for the inconvenience.
