TemplateUIExtension and BC4J

Hy, I have write some new composants with template.
And grouping all with templateLibrary.
<?xml version="1.0" encoding="windows-1252" ?>
<templateLibrary xmlns="http://xmlns.oracle.com/uix/ui" >
<templateImport source="link.uit" />
<templateImport source="label.uit" />
</templateLibrary>And now I would like to import template file for using my new component in JAVA API.
I have create my own UIExtension, and use here
      <param-name>oracle.cabo.ui.UIExtensions</param-name>
      <param-value>oracle.cabo.data.jbo.ui.JboUIExtension,myPckg.myUIExtension</param-value>It's work fine but parser make a error on loading OC4J with template use BC4J tag.
All my template don't use BC4J work but with BC4J a have a parsing error.
However these templates work well if I import them with the standrad method.
<templates xmlns="http://xmlns.oracle.com/uix/ui">
    <templateImport source="template/library.uit"/>
</templates>Thanks you for your help,
Nathanael

can you please tell us what the parsing errors are?
This might be caused by having a UIExtention that depends on another UIExtension. I will find out if that is supported.

What is the best way of deploying a jsp and bc4j aplication

Hi
I would like to know what is the best way of deploying a jsp and
bc4j aplication in ias 9i.
thanks in advanced
rjc

In the page I simply referenced the facescontext directly... no need for a custom servlet.
public void createcookie() {
FacesContext fc = FacesContext.getCurrentInstance();
HttpServletResponse resp = (HttpServletResponse)fc.getExternalContext().getResponse();
Cookie userCookie = new Cookie("cookiename", "cookievalue");
userCookie.setMaxAge(-1);
userCookie.setMaxAge(3600);
resp.addCookie(userCookie);
return null;
public String readcookie() {
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
Map cookiemap = ec.getRequestCookieMap();
if (cookiemap != null) {
Cookie cookie = (Cookie) cookiemap.get("cookievalue");
return cookievalue;
For reference I could not get getCookies() method of HttpServletRequest to work.. it would only return JSESSIONID.

Error executing a query using VPD and BC4J

Hi all,
Our team is developing an application using an Oracle DB 9.2.0.4 and BC4J 10g (9.0.5.16.0) as persistence layer.
We also are using the VPD (virtual private database) to have security in the database at row level.
The problem we are facing is that every some time (days) we get a jdbc error when a query (see below) that uses VPD policies is executed. Once the error occurs I execute it from sqlplus without getting any error .. it only occurs from our java application.
To temporary solve this problem, we delete and recreate the VPD policies, then the application continue working fine for some time ...
I'll appreciate any comment / suggestions
Thank in advance.
Eduardo.

How to Change Package of project and BC4J package

I need to change the package of existing project and BC4J, before it was oracle.apps.xxcm.cms new package is oracle.apps.xxdl.cms, is there any way to change so that the entire BC4J packages Vo's EO's and java class files should change.
Thanks
Babu

Babu, what Tapash said is correct the only option remains is to chaging package name in all files using grep and then manually changing the directory structure.

Strut tile definition and bc4j

Hi ,
I am working on a BC4j Struts based project.I was on my way to implement tile definition thru a xml file and implementing do action forwards,for ex welcome.do,viewreport.do.For doing this I had to change the controller entry in struts-config.xml from
<controller debug="3" locale="true" processorClass="oracle.jbo.html.struts11.BC4JRequestProcessor" contentType="text/html;charset=windows-1252"/>
to
<controller processorClass="org.apache.struts.tiles.TilesRequestProcessor" contentType="text/html;charset=windows-1252"/
after I did this the actions I had implemented myself with to work with tile defs,they are working fine ,but there were some other actions(as I started with a wizard created bc4j strut app) which are bc4j related have stopped working because BC4JRequestProcessor was no more
defined as the request processor....
How to solve this?How to make both strut actions and bc4j actions work inside a project...can 2 request processors be used at the same time...
can anybody help??

Struts 1.2.4 and BC4J in JDev 9.0.3.4

Hi,
I did some sample code using Struts and BC4J in JDev 9.0.3.4. I was using the Struts version that came with the JDev.
Then I downloaded Struts 1.2.4 and unpacked it instead of the shipped version and backed up the old one. I did another sample application in a new project and it gave me this error
java.lang.NoSuchMethodException: Bean has no property named application
It's not recognizing the
<set-property property="application" value="TPSModule"/>
in the struts-config.xml file.
When I restore the old version libraries in the WEB-INF/lib, everything works fine.
Can I not use Struts 1.2.4 with JDev 9.0.3.4?
Any help is appreciated.

No the article is not applicable for 9.0.3 I've never tested the compatibility of the 9.0.3 + Struts integration - obviously it does not work.
What does work is the ADF bindings used in 9.0.5 and above which can be safely used with newer versions of Struts.

OC4J and BC4J Runtime installation for Solaris (Unix)!

We have successfully installed, configured and deployed JSP/BC4J apps using OC4J and BC4J on Windows NT/2000. However, our production environment is Solaris.
We have installed OC4J on Solaris, with some difficulties. How/where is the installation process for the BC4J Runtime Installation? The download (bc4j-ojsp.zip) for this utility is Windows only.
Is there a method or process to install BC4J Runtime on Unix? If not, we are stuck.
We cannot use JServ (servlet limitations) and refuse to use OSE (to many issues).
Any guidance or assistance would be greatly appreciated...

Stephan,
I have located multiple "connections" files and will remove all but the default located in the OC4J classes directory. We have been developing with JDeveloper and it often created multiple connections files that appear when you "jar" project components.
We also installed JDK1.2.2_008 and are using this. However, when I use the classpath method of starting OC4J, I receive numerous errors. Using the jar method, everything works, with the exception of BC4J apps. I'll have to look into the errors more.
Thanks for the response. At least I know one other person (organization) is using this successfully. I hope to join the "success" crowd tomorrow!
Thanks again...

OC4J and BC4J

Hi All,
What is OC4J and BC4J ?? What is the basic difference between them.
I know there is a lot of documentation on OTN on these, but they are very detailed. I just need to know the basic concept and difference between the two.
Thanks!!

Are JDev9i UIX and BC4J application server dependent?

Are UIX and BC4J application server dependent?
If I use JDeveloper9i to build an application using UIX XML + BC4J + Java, then can this be deployed on IBM Websphere, Web Logic, Oracle 9iAS, etc...?

BC4J and UIX are not tied to any application server. They are "just" a collection of jar files that you can deploy to any application server.
Check out the how-to section to see the doc about deploying BC4J to other application servers at:
http://otn.oracle.com/products/jdev/howtos/content.html
(more info in the online help).
Also check out otn's home page later today for a daily feature about BC4J openness.

UIX/XML and BC4J -- practical???

Has anyone actually used UIX/XML and BC4J to develop a "real" application? The majority of the examples in the help screens use jsp's, yet the comparisons I've read in the help screens seem to indicate that XML is more flexible.
UIX/XML seems like such a clever concept, I like the idea, but it's getting the best of me. Should I jump ship now?
Any comments please!
js

Examples are definitely what's needed and I put my request for a full blown MVC application using UIX/XML (without BC4J in my case) to Adam a while ago which was forwarded to the 'management'. Hopefully something will come from this soon. I agree with Janet that UIX is a great concept (don't jump ship yet!) and it should save us so much work but that real world examples would surely help us all. No disrespect, Juan, but you regularly respond to people's questions with 'Have you read the UIX developer's guide provided in the documentation' - we've all read the documentation many times, if only it were that simple! I'm sure it's easier for someone inside Oracle to get the answers they need whereas we on the 'outside' have to rely on this forum for now which is a struggle.
Bill's idea of illustrations would be great, though I'd like to see the examples relate to the sample screens show on the BLAF standards website. I only found out about the BLAF website accidentally through this forum. The UIX Developer's Guide should explicity reference this as I've found it extremely useful.
Ed,
The UIX Developer's Guide is in the JDeveloper Help.

JSP and BC4J archithecture

Hi,
Anyone can help me to choose a archithecture to build a
internet/intranet with jsp and bc4j.
Thanks in advanced
rjc

Hi Mike,
Thanks for your reply.
In the Emp form, it would look like:
Emp Name, Emp BirthDate, ... Dept No.
I would like a list available on the Dept No item (field), which lists the DEPT records when insert/create a new EMP record, i.e. this list helps to fill the DEPTNO instead of typing the key, like 1234, manually. Would Jdev do it for me? or I have to manually code this after I get the code from "new->Web-tier->jsp4BizComponents->CompleteJSP Application"
Thanks
Mark

EJB entity beans and BC4J

I have looked at BC4J and it looks good. Buy my question is that isn't this frame work in direct conflict with EJB entity beans. I know lot of stuff that is there in BC4J should have been in EJB enitiy beans, but as a developer why should I go with BC4J and not the standard EJB stuff considering the fact that BC4J is properietery to Oracle?Any thoughts?

Vimal,
Without going into exhaustive detail here, I would like to recommend that you take a look at the BC4J Technical White Paper available from the JDeveloper page on OTN (in the 3.0 Technical Information section):
http://technet.oracle.com/products/jdev/info/techwp20/wp.html
Amoung other things to note, BC4J is based on pure Java, and is what we consider a 'white box', meaning, you as a developer have complete control over what is going on. You can extend any of the code generated to customize it.
Primarily though, the major benefit of BC4J is that we have taken care of most of the complicated communication code for you. Communication between the client and the data server, transaction handling, row locking, etc are already written for you. You just use, extend, customize what we have provided.
In addition, BC4J allows you flexibility in your deployment environment decision. Regardless of where and how you deploy your BC4J Application Module, the client is unchanged.
Those are the key advantages. Again, for more details, I would take a look at the white paper to see if it more fully addresses your questions.

Java Web Start and BC4J/OC4J

Hi all developers,
This is my first forum message, and I hope that there is someone that can help me.
Problem: A JClient using BC4J in a 3tier situation work perfectly well when run from within the IDE, however using the Web Start Wizard and deployed to the Application server and run from Java Web Start, it does not work.
Is there any HowTo or documentation on the right settings, roles, security, procedures, etc. with regard to Jclient, BC4J and Java WebStart?
Thanks
Craig

Object Type database and BC4J

Hi everybody
I have an object type defined in oracle and I attached that type to one of my tables as a type of a column in that type, assume addr type and table customer with column address
and its type addr.
In BC4J , I created a domain for the type and after that, I added an entity object for my table and I chose the type of that column as the domain I created, after that view object and after that application module.
Now I want to test my application module.
It doesn't bring the fields of that type for data entry. how can I enter something inot my address column?
Please help and thanks for that.

Specifically, see the "Batch Client Tutorial" which is part of the following sample Workspace:
.\samples\BC4J\OrderEntry\OnlineOrdersForClients\OnlineOrdersForClients.jws
The TestClient.java and TestClient2.java files illustrate best-practice techniques for using the BC4J client API's for working with master/detail coordinated rowsets in a tier-independent manner using the basic oracle.jbo.* interfaces, as well as custom interfaces that expose methods to the clients. TestClient2.java illustrates working with an attribute of (domain) type TAddress which was created on top of an Oracle8 type T_ADDRESS.

URGENT- PLEASE HELP: java.lang.threads and BC4J

Hi,
according to my issue "no def found for view" in the same titled thread I'm wondering how you would implement asynchronous calls of methods that use BC4J to update a couple of data.
To be more precise:
A requirement of our software is to start an update database job, which can take a couple of minutes/hours, from the web browser. Before it will be executed the logged-in user receives a notification that this batch job has been started.
I dont't want to use JMS overhead and MD Beans for this simple requirement, therefore I implemented a class that extends java.lang.Thread and put all the update codings within the run method. After having called the start-method of the thread I get a JBO-25022(No XML file found) error when I try to set a new value for an attribute of the row. The row consists of attributes which belong to four entity objects that mus be updated.
When calling the run method directly, everything works fine.
My questions:
* do you know any workaround how to make the xml files
reachable?
* how would you implement anschronous calls of long time-
consuming jobs?
* is this a bug of BC4J?
Any help, tip, hint is really appreciated.
Stefan

Arno,
many thanks for your reply:
Here is an excerpt of the source code of my thread "Aenderungsdienst":
public class Aenderungsdienst extends java.lang.Thread
private SviAdministrationModuleImpl mSviModul;
// Application module that contains view object
// IKViewImpl
public Aenderungsdienst(SviAdministrationModuleImpl aSviModul)
mSviModul = aSviModul;
public void run()
ausfuehrenAenderungsdienst(mAenderungsdienstNr); <--error within this methode
private int ausfuehrenAenderungsdienst(String aAenderungsdienstNr)
int rAnzahlSaetze = 0;
try
IkViewImpl aenderungen = mSviModul.getIkView();
aenderungen.suchenAenderungssaetze(aAenderungsdienstNr); <-- method within View Object Impl that executes a query with customized where-clauses
if ((rAnzahlSaetze = aenderungen.getRowCount()) > 0)
IkViewRowImpl ik = null;
while (aenderungen.hasNext())
ik = (IkViewRowImpl) aenderungen.next();
ik.setBestandsstatus("B"); <-- error occurs here when setting the status of a current row in my rowset to "B"
mSviModul.getTransaction().postChanges();
mSviModul.getTransaction().commit();
catch (Exception e)
e.printStackTrace();
mSviModul.getTransaction().rollback();
//todo: Verarbeitungsprotokoll erstellen
return rAnzahlSaetze;
This thread will be called by the application module "sviAdministrationModuleImpl":
public void ausfuehrenAenderungsdienst(String
aAenderungsdienstNr)
Aenderungsdienst aenderungsdienst = new
Aenderungsdienst(this);
aenderungsdienst.setAenderungsdienstNr
(aAenderungsdienstNr);
aenderungsdienst.start();
Using the start() method of the thread causes this exception:

Using run(), everything works perfectly.
The view object IKView consists of four entity objects which are linked by associations. There exists an association between the entity objects ik and inlandbankverb. The xml-file for the association object is named "ik_inlandsbankverb.xml". It seems so that this definition could not be found when calling my thread in asynchronous (via start()-method call) mode.
Is this a bug of JDeveloper?
Thanks in advance,
Stefan
