ADF Model Validation using JPA/EJB stack.
Hi,
We are evaluating 11g and are interested in implementing using a JPA/EJB3.0/Toplink - EJB Session Bean - ADF bindings - ADF Faces RC stack.
Looking at the declarative validation rule framework, I am trying to determine whether I can define domain model validation rules that can be propagated up through to the ADF faces RC layer. We have looked previously, at the ADF BC framework and note that it can be done there, but we wish to use a pure EJB/JPA solution.
I can see how validation rules can be declared at the page bindings layer in the pageDef file, and this all works. However, these same validation rules applied to the Structure Definition <entitybeanname>.xml file, do not propagate up through the ADF binding layer, although the xsd of the structure definition file does appear to support it. The documentation I have read is somewhat ambigious as to whether this is possible.
Basically, it would be nice to have some form of domain attribute validation that can be defined against the entity bean attributes that is available in the service and UI layer ala Hibernate Validator etc...
Anyone, got any suggestions?
regards,
andy
I'm not sure I understand what the "ADF own transaction operation" is. Could you explain?
If you have to write your own persist method, what's the proper way to go about doing this? Is there a tutorial to be found somewhere? What I have now has been created by following the tutorial linked above, I haven't modified the code yet. Looking at the code I found this:
jTable1.setModel((TableModel)panelBinding.bindUIControl("tableNameFindAll",jTable1));
Where tableNameFindAll is related to a named query TableName.FindAll.
There seems to be a data structure named "UpdateableCollection" which provides the operations such as 'create', 'next', 'first', etc. Would a subclass of this be the proper place to put a 'commit' function? I'm assuming through the bind control I could gain access to either this UpdateableCollection or the list of entities (List<tableName>) then I suppose I could go through this list and persist the new ones. But I think this doesn't fit with the paradigm as these are data control operations not interface operations. So I'm wondering where should I put the 'commit' operation (which should both add new data and merge the updated data) and how do I bind it to the interface? I just couldn't find a tutorial explaining all of this, but perhaps it's out there.
Thanks.

Problem when using JPA/EJB in webservice
I wrote a web service that use JPA/EJB to connect to Sybase (the existing tables), and deployed to OC4J, but it got the following error when the web service is invoked:

I have checked that, the query will return some records, and also it works fine if the program executed as a stand alone application.
Thanks in advanceI find that I can only have ONE webservice that using JPA/EJB for an OC4J instance, if more than one then the above error will come out, and I have to restart the OC4J instance to run another webservice that using JPA/EJB.
Is there any solution for this issue?

ADF Email Validation using Regular Expression
Hi,
Wanted to add Email Validation VO search.
It is working if i put
<af:validateRegExp pattern="[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}"
messageDetailNoMatch="The value {1} is not a valid email address:"/>However this requires email id to be entered in Capital Letters.
Tried with below option is not working.

Hi All
In a new project I am going to use JPA / EJB session beans and ADF Faces
Also I am going to use similar pattern described in below link for a GenericDAO
and inject instances of Generic EJB into my business EJBs
http://www.adam-bien.com/roller/abien/entry/generic_crud_service_aka_dao
https://blogs.oracle.com/theaquarium/entry/generic_jpa_dao_repository_implementation
In second link some people mentioned this way is old and over simplified
Any body have any comment / ideas or similar cases
I don't want use any external open source libraries
Thanks
MohsenI've read that article several months ago and didn't get a chance to try it out. However, I did work with Hibernate quite a bit.
I believe the author would have us replace this:
public update(Person person){
with this:
public void update(T o) {
In the first function, its obvious that I'm updating a record in the Person table.
In the second function, I need to have a list of all the possible table names (such as 'Person') to know which tables have an update function associated with it that I can use with the generic function. For example, some tables may be read-only and dont have an update function.
Normally, the compiler helps you out by providing a dropdown list of functions an object has that you can choose from.
Likewise, the compiler will have a dropdown list of all the different arguments (signatures) a function has.
I dont think the generic function will provide this. As an end-user calling up a Hibernate function that you wrote, I want help from the compiler on what my options are. I don't want to dig into the Hibernate configuration file to determine weather update is allowed for a table or not.
The downside of not using generics of course, is you have to write a DAO with CRUD functions for each and every table in the database (actually, for every graph, but lets not get into that).
Also, I don't see an example of how the associations between tables is implemented in generics. For example, one to many relationships, etc. A developer may get bogged down trying to get generics to work for all those possiblies (then again, perhaps not, since I didn't try it).
By the way, I don't see anything about generic DAO on the internet younger than 2 years old so I suspect it hasn't caught on. -
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 AMI 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.

How to create a cache for JPA Entities using an EJB
Hello everybody! I have recently got started with JPA 2.0 (I use eclipseLink) and EJB 3.1 and have a problem to figure out how to best implement a cache for my JPA Entities using an EJB.
In the following I try to describe my problem.. I know it is a bit verbose, but hope somebody will help me.. (I highlighted in bold the core of my problem, in case you want to first decide if you can/want help and in the case spend another couple of minutes to understand the domain)
I have the following JPA Entities:
@Entity Genre{
private String name;
@OneToMany(mappedBy = "genre", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<Novel> novels;
@Entity
class Novel{
@ManyToOne(cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Genre genre;
private String titleUnique;
@OneToMany(mappedBy="novel", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> editions;
@Entity
class NovelEdition{
private String publisherNameUnique;
private String year;
@ManyToOne(optional=false, cascade={CascadeType.PERSIST, CascadeType.MERGE})
private Novel novel;
@ManyToOne(optional=false, cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Catalog appearsInCatalog;
@Entity
class Catalog{
private String name;
@OneToMany(mappedBy = "appearsInCatalog", cascade = {CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> novelsInCatalog;
The idea is to have several Novels, belonging each to a specific Genre, for which can exist more than an edition (different publisher, year, etc). For semplicity a NovelEdition can belong to just one Catalog, being such a Catalog represented by such a text file:
FILE 1:
Catalog: Name Of Catalog 1
"Title of Novel 1", "Genre1 name","Publisher1 Name", 2009
"Title of Novel 2", "Genre1 name","Pulisher2 Name", 2010
FILE 2:
Catalog: Name Of Catalog 2
"Title of Novel 1", "Genre1 name","Publisher2 Name", 2011
"Title of Novel 2", "Genre1 name","Pulisher1 Name", 2011
Each entity has associated a Stateless EJB that acts as a DAO, using a Transaction Scoped EntityManager. For example:
@Stateless
public class NovelDAO extends AbstractDAO<Novel> {
@PersistenceContext(unitName = "XXX")
private EntityManager em;
protected EntityManager getEntityManager() {
return em;
public NovelDAO() {
super(Novel.class);
//NovelDAO Specific methods
I am interested at when the catalog files are parsed and the corresponding entities are built (I usually read a whole batch of Catalogs at a time).
Being the parsing a String-driven procedure, I don't want to repeat actions like novelDAO.getByName("Title of Novel 1") so I would like to use a centralized cache for mappings of type String-Identifier->Entity object.
Currently I use +3 Objects+:
1) The file parser, which does something like:
final CatalogBuilder catalogBuilder = //JNDI Lookup
//for each file:
String catalogName = parseCatalogName(file);
catalogBuilder.setCatalogName(catalogName);
//For each novel edition
String title= parseNovelTitle();
String genre= parseGenre();
catalogBuilder.addNovelEdition(title, genre, publisher, year);
//End foreach
catalogBuilder.build();
2) The CatalogBuilder is a Stateful EJB which uses the Cache and gets re-initialized every time a new Catalog file is parsed and gets "removed" after a catalog is persisted.
@Stateful
public class CatalogBuilder {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private Cache cache;
private Catalog catalog;
@PostConstruct
public void initialize() {
catalog = new Catalog();
catalog.setNovelsInCatalog(new ArrayList<NovelEdition>());
public void addNovelEdition(String title, String genreStr, String publisher, String year){
Genre genre = cache.findGenreCreateIfAbsent(genreStr);//##
Novel novel = cache.findNovelCreateIfAbsent(title, genre);//##
NovelEdition novEd = new NovelEdition();
novEd.setNovel(novel);
//novEd.set publisher year catalog
catalog.getNovelsInCatalog().add();
public void setCatalogName(String name) {
catalog.setName(name);
@Remove
public void build(){
em.merge(catalog);
3) Finally, the problematic bean: Cache. For CatalogBuilder I used an EXTENDED persistence context (which I need as the Parser executes several succesive transactions) together with a Stateful EJB; but in this case I am not really sure what I need. In fact, the cache:
Should stay in memory until the parser is finished with its job, but not longer (should not be a singleton) as the parsing is just a very particular activity which happens rarely.
Should keep all of the entities in context, and should return managed entities form mehtods marked with ##, otherwise the attempt to persist the catalog should fail (duplicated INSERTs)..
Should use the same persistence context as the CatalogBuilder.
What I have now is :
@Stateful
public class Cache {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private sessionbean.GenreDAO genreDAO;
//DAOs for other cached entities
Map<String, Genre> genreName2Object=new TreeMap<String, Genre>();
@PostConstruct
public void initialize(){
for (Genre g: genreDAO.findAll()) {
genreName2Object.put(g.getName(), em.merge(g));
public Genre findGenreCreateIfAbsent(String genreName){
if (genreName2Object.containsKey(genreName){
return genreName2Object.get(genreName);
Genre g = new Genre();
g.setName();
g.setNovels(new ArrayList<Novel>());
genreDAO.persist(t);
genreName2Object.put(t.getIdentifier(), em.merge(t));
return t;
But honestly I couldn't find a solution which satisfies these 3 points at the same time. For example, using another stateful bean with an extended persistence context (PC) would work for the 1st parsed file, but I have no idea what should happen from the 2nd file on.. Indeed, for the 1st file the PC will be created and propagated from CatalogBuilder to Cache, which will then use the same PC. But after build() returns, the PC of CatalogBuilder should (I guess) be removed and re-created during the succesive parsing, although the PC of Cache should stay "alive": shouldn't in this case an exception being thrown? Another problem is what to do when the Cache bean is passivated. Currently I get the exception:
"passivateEJB(), Exception caught ->
java.io.IOException: java.io.IOException
at com.sun.ejb.base.io.IOUtils.serializeObject(IOUtils.java:101)
at com.sun.ejb.containers.util.cache.LruSessionCache.saveStateToStore(LruSessionCache.java:501)"
Hence, I have no Idea how to implement my cache.. Can you please tell me how would you solve the problem?
Many thanks!
ByeHi Chris,
thanks for your reply!
I've tried to add the following into persistence.xml (although I've read that eclipseLink uses L2 cache by default..):
<shared-cache-mode>ALL</shared-cache-mode>
Then I replaced the Cache bean with a stateless bean which has methods like
Genre findGenreCreateIfAbsent(String genreName){
Genre genre = genreDAO.findByName(genreName);
if (genre!=null){
return genre;
genre = //Build new genre object
genreDAO.persist(genre);
return genre;
As far as I undestood, the shared cache should automatically store the genre and avoid querying the DB multiple times for the same genre, but unfortunately this is not the case: if I use a FINE logging level, I see really a lot of SELECT queries, which I didn't see with my "home made" Cache...
I am really confused.. :(
Thanks again for helping + bye -
Using an EJB as a source for a Model
Hi,
Before starting with this post content it might be helpful to give you the desired output of what I am trying to do. Basically I need to have an HTML table that is populated from an EJB.
The current proposed solution is as follows: the Model that is associated with a TiledView will be used as client for the EJB. The Model will make use of the methods in the EJB to get different java.util.Collection objects for different Helper classes based on the find criteria.
For example, if the EJB represent a book and there is a home method to retrieve a list of books based of the book category. In this case the Model will act as a client of the EJB, retrieve the list of books and use the different methods in the Model, such as insert and retrieve, to get the list of books and to add a book up on request.
I know that my post might not be clear. But as I said, all that is needed is to have a TiledView that displays books information, which are retrieved from an EJB, and allow a user to select a book to display its information.
My suggested solution could be completely wrong, not visible and reflect a bad design. Please if any one went through such a situation give me a hint.
Regards,
Basil MahdiBasil,
This is some material I snipped from an internal Sun forum I posted to regarding a simple EJB Jato integration example.
I hate to give just any EJB JATO example because frankly there are so many different use cases with EJBs that no one example will match up against your needs. You can use an EJB
- in a Custom Model Operation you can encapsulate an EJB Method invocation
- in a Custom Command you can encapsulate any arbitrary code include calling an EJB
- as the backingstore for a CustomModel
- use a BeanAdapterModel to adapt to the value/transfer beans which are uses as parameters or return values of EJB methods
- use an ObjectAdapterModel to adapt an EJB directly by assigning the EJB reference in setObject() in the constructor of the OAM
As you can see, an EJB is just another business object API...its just that you acquire the reference with a few lines of ugly JDNI and Home interface APIs.
Nevertheless, here is some guidance. I would like to reinforce that there is no direct solution for adapting an EJB from BAM; EJBs are not JavaBeans. What is a solution is to have the parameters or return values of your EJBs use value/transfer object patterns in the form of JavaBeans. The BAM may be used to adapt to these parameters or return value of the EJB.
In short, when using BAM in a tileview to work with an EJB, there is little difference than using BAM at any other time, you the developer, must manage/code the placement of the EJB parameters directly into the BAM or in a scoped attribute to be used by the BAM.
In another example, you may have a SLSB which models an employee called EmployeeSupport. You may have a transfer object (JavaBean) of type EmployeeRecord. You may have operations on the EJB including:
public EmployeeRecord findEmployee(String employeeID);
public EmployeeRecord[] findEmployees(String location);
public void updateEmployee(EmployeeRecord);
One could create a BAM in the studio called EmployeeModel
You would set the JavaBean class to EmployeeRecord
You would run the Design Action to bootstrap the properties of EmployeeRecord as fields on the model
Now you have a model which is ready to adapt to EmployeeRecord bean.
Feel free to add material to the EmployeeModel to make a richer API; for instance you could encapsulate some EJB'ish code in their to act as a service locator for a EmployeeSupprt SLSB.
protected static EmployeeSupport support;
static {
javax.naming.Context context = new javax.naming.InitialContext();
Object objref = context.lookup("ejb/EmployeeSupport");
EmployeeSupportHome home = (EmployeeSupportHome)
javax.rmi.PortableRemoteObject.narrow(objref,EmployeeSupportHome .class);
support = home.create();
public static EmployeeSupport getEmployeeSupport() {
return support;
If you really wanted to hide the EJB'ishness of the EmployeeSupport you could even wrap the behavior and handle exceptions, etc.
public static EmployeeRecord findEmployee(String employeeID) {
return getEmployeeSupport().findEmployee(employeeID);
public static EmployeeRecord[] findEmployees(String location) {
return getEmployeeSupport().findEmployees(location);
public static void updateEmployee(EmployeeRecord record) {
return getEmployeeSupport().updateEmployee(record);
You could even help the view developer latch EJB transfer objects into the model for adaption; saving them from the effort
public void adaptEmployee(String employeeID) {
setBean(findEmployee(employeeID));
public void adaptLocation(String location) {
setBean(findEmployees(location));
public void save() {
updateEmployee((EmployeeRecord)getBean());
Create a search ViewBean, place a text field on it for an EmployeeID and button labeled Find. Leave the EmployeeID model binding default (to use a DefaultModel memory model). Open the handle request event method on the viewbean for the Find button.
public void handleFindRequest....{
EmployeeModel model = .....;
model.adaptEmployee(getEmployeeIDChild().getValue());
// display Edit page which has fields for editing the employee record
Create an edit ViewBean, with editable fields bound to the EmployeeModel; add an button labeled update
public void handleUdpateRequest....{
EmployeeModel model = .....;
model.save();
// do whatever is next ....
Notice that the we are jumping across request boundaries in this example. Using just default model reference configurations, the EmployeeModel will be created brand new during the Update request and there will be no bean currently adapted. Most likely, you would want to have the model (and hence its adapted bean) stored in HttpSession across at least these related requests. In this case the model reference used by the search ViewBean would have "store in session" true. and the model reference in the edit ViewBean would have "look in session" true.
What we recommend is that someone who understands the business tier design take the responsibility to create a set of "business delegates" as JATO models. An advanced technique would be to encapsulate these models in a component library JAR which multiple web applications can reuse. As you can imagine, there are so many ways to do the same thing. You could just as easily make a CustomModel or SimpleCustomModel to adapt to your EJB. You can also, if your EJB uses primitives or JavaBeans (or graphs of JavaBeans) for all parameters, use the ObjectAdapterModel to directly connect to an EJB. -

VIpinHi Frank
Thanks for the help, this Iterator is coming from the BPM, so rows and attributes should be there, I am able to fetch the rows and attribute in my bean as I updated.
Now if the things updated is wrong then how can I iterate through the all rows in my jspx page, using a foreach.
Thanks

Thanks for ur reply...
we are using unbounded taskflow.
In Controller class(page def file), we refered the class that implements PagePhaseListener
The following override methods has created
public void afterPhase(PagePhaseEvent pagePhaseEvent) {
//In this area we used to read the session object file which is written and sent by another application(application to application navigate).
If session object file exists,will allow the user to navigate into the requested page else will navigate in to login(security aspect).
public void beforePhase(PagePhaseEvent pagePhaseEvent) {
Is we used Controller class wrongly ???
Is there any relationship with region controller???

Can't use JPA facet in a Workshop 10.3 EJB project
Greetings,
I'm using Oracle Workshop for WebLogic 10.3 to migrate an enterprise application from JBoss 5.0 to WebLogic 10.3. I'm a bit confused as, while I can add the JPA facet to a Dynamic Web project, I cannot do the same with an EJB project. I'd need to take advantage of the IDE automatic facets management instead to manually dealing with libraries and dependencies. I beleive that this is the reason these facets exist. However, after having created a EJB 3.0 project, it is impossible to add to it the JPA facet. I had to define the JPA entities in a Dynamic Web project as this is the only one to which I can add the JPA facet. This is not regular. Additionally, the SLSB facades may only be defined in an EJB project. They reference the JPA entities in the Dynamic Web project which, given the class loading hierarchy, is not possible. So my question is: how is one supposed to use JPA with WTP projects ?
Many thanks in advance for any help,
NicolasThis isn't supported in Workshop 10.3 and prior, the JPA tooling only works with Dynamic Web Projects in those releases to my knowledge.
I think this changed in OEPE 11g. Check out this article that shows JPA being used in the context of a Utility Project:
http://www.oracle.com/technology/pub/articles/cioroianu-eclipse-jpa.html

How can i use oracle coherence with JPA/ejb in web service?
Hi
I want to make web service using JPA which calls oracle XE via oracle coherence? i want to use JAX-ws? i searched and found you can make and deployed it using web logic but is there any other way i can make it and deployed in tomcat. i want to use oracle coherence + Oracle XE + JAX-WS? if it possible how can i other wise what are other ways i can do it?
please any one does know it reply please it helps me lot to get.
Thanks in advance,
Edited by: 913837 on Feb 22, 2012 3:51 PMIf you want data cached in Coherence to find it's way into an Oracle database for persistence, then look at the "CacheStore" section of the Coherence Developer Guide. This also works the other way round too, in that you can get data read into a Coherence cache via a database read. Again, look in the Coherence Developer Guide.
If you want you applications "entry point" into a piece of code to be a web-service, then Tomcat+CXF will work just fine. Once you are in the service, just use the Coherence API to put the data in a cache.
But also look at the HTTP access offered in later versions of Coherence in the form of REST. This may save you the Tomcat+CXF install, depending upon your needs. See the Coherence Client Guide.
Still, what exactly are you trying to achieve here? It's not clear from your post why a web service using JPA for persistence needs to go via Coherence at all. More info needed.
Cheers,

Issues in ADF mobile application using Trinidad components
I am facing the following issues when developing a mobile application using trinidad components :
Jdev version : 11.1.1.6
1) I dont see a date component using trinidad components? The dev guide http://docs.oracle.com/cd/E23943_01/web.1111/e10140/sup_comp.htm says that tr:inputDate is supported but when i try to drag a data field to jsf page i don't see an option for Trinidad date component. so i went ahead and created an af:inputDate in the page. But the date selection dialog doesnt open up.
2) i tried using 'Rendered' for conditional rendering of a component but it does not work or refresh immediately, the same problem is solved in my adf application using visible property but looks like there is no 'Visible' property for Trinidad components. any work around?
3) i wanted to have a 'create insert' call in my task flow before launching the page. Since Task flows are not supported in ADF mobile application, i have added 'ADF Faces' also into my project and created task flow and jsff page as i do for a adf web application the only diff being the usage of trinidad components in my jsff page. is this fine? Also can we mix trinidad components and adf components into the same page?
4) I have a tr:inputText on a clob input text field which i am updating in ADF page using a clob converter class. Same thing i cannot do for trinidad text as it is resulting in null pointer exception. any solution to update clob fields into database which uses tr:inputText compents.
Help to solve any one of the above issues (by quoting serial no) would be highly appreciated. Thanks.>
4) I have a tr:inputText on a clob input text field which i am updating in ADF page using a clob converter class. Same thing i cannot do for trinidad text as it is resulting in null pointer exception. any solution to update clob fields into database which uses tr:inputText compents.
wht is the stack trace.. when is it giving null pointer exception.. explain

Below is the code for an inputText component based on a CLOB Field.
<tr:inputText value="#{bindings.ObsComments.inputValue}"
label="#{bindings.ObsComments.hints.label}"
required="#{bindings.ObsComments.hints.mandatory}"
columns="#{bindings.ObsComments.hints.displayWidth}"
maximumLength="#{bindings.ObsComments.hints.precision}"
id="it4" rows="4" binding="#{ObsMobileBean.obsComments}"
showRequired="#{bindings.WoNeeded.attributeValue eq 'Y'}"
partialTriggers="sbc1" converter="ClobConverter">
<f:validator binding="#{bindings.ObsComments.validator}"/>
</tr:inputText>When i try to render the page it self i face this error initially.

Let me know if anyone got any clues?User,
Apparently, you are an Oracle developer working on Fusion Apps. It seems to me it would be more appropriate to ask in an internal forum, seeing as that most of us here have no access to the software you're using.

Looks like you are using a java.util.HashMap somewhere in your model, and that hash map is being modified by more than one user/thread at the same time...
[url http://download.oracle.com/javase/1.4.2/docs/api/java/util/HashMap.html]Documentation for java.util.HashMap says:
Note that this implementation is not synchronized. If multiple threads access this map concurrently, and at least one of the threads modifies the map structurally, it must be synchronized externally.You need to use something other than a hash map.
