Creation of Application module - JClient
How can I create two instance of the same application module?
Now, my application has 2 frame that should work indipendtly (indipendent transaction), instead the frame are sinchronized.
I see that the hashCode() of JUApplication module is different, instead the .getApplicationModule() is the same.
What I have to do to create an other instance of applicationmodule instead of using a "pool".
Thanks
Please, give me the code for a JClient connection.JClient source is shipped with JDev and could be found in (JDEVHOME)\bc4j\src\bc4juisrc.zip
oracle.jbo.common.Configuration is Deprecated
My mistake. See oracle.jbo.client.Configuration for methods to create an application module from a "configuration" name.
JUMetaObjectManager.setApplicationObject(...) return no value (void). You can call JUMetaObjectManager.findApplicationObject(withTheGivenQualifiedName) to get the JUApplication object created in set...

Creation of Application module failed
Hi all,
I'm trying to deploy BC4J as EJB on OAS4.0.8.2 (OAS and Oracle 8.1.6 on Solaris 2.7). Deployment went OK, I can open Business Component browser but in Object Members View I can see only 2 records for each view (looks like recordset properties?), also I cannot create, update, delete a record. When I'm trying to create app. module I getting "Unknown remote exception: CORBA: org.omg.CORBA.INTERNAL: minor code: 0 completed: No; nested exception is: Everything is working fine when I'm testing BC locally.
Thanks.

BC4J Application Module Pooling for JClient App
Helo,
i wonder why all documentation about bc4j application module pooling available is for Web app ? (jsp) . I'm creating swing JClient app and i need some doc about how the application module pooling works in this kind of application.
anybody know where can i get those docs ?
Need help and Thank you,
Ricky H.P.Connection pooling can be achieved when a JVM instance manages the pool, in 3tiers the Java App. Server has that task.
If you are 2tiers that means that you are communicating with the database through JDBC.
When a user launches your JClient app in fact he lauches his own JVM instance so I don't how he could share a pool with other users.
In your case you have at most 2 open transactions per user.
You can achieve that by sharing a same binding context with n forms composed of m panels.
Let's say:
1 main form
connection 1: forms a,b,c
connection 2: forms x,y,z
In your main form your open your 2 connections and share them.
You can achieve that by:
1) in our main form, initialize 2 binding containers
Example of one:
DCBindingContainer bc1 = this.createBindingContainer("package name","model name");
private DCBindingContainer createBindingContainer(String packageName, String panelModelName)
StringBuffer sb = new StringBuffer(packageName);
sb.append(ViewConstants.STRING_DOT);
sb.append(panelModelName);
DCBindingContainerDef bcdef = DCBindingContainerDef.findDefObject(sb.toString()); //NOTE THE NAME.
if (bcdef == null)
throw new JboException("System error, "+getClass().getName()+".createBindingContainer, DCBindingContainerDef: "+sb.toString()+" not found");
DCBindingContainer bc = bcdef.createBindingContainer(panelBinding.getBindingContext());
bc.setName(panelModelName);
panelBinding.getBindingContext().put(panelModelName, bc);
return bc;
2) Before that the jbInit method gets called in the called form, set the binding context:
form1 = new Form1(...);
form1.setBindingContainer(bc1) ;
Example of methods in form 1 and form 2:
public void setBindingContainer(DCBindingContainer ctr)
this.panelBinding = (JUPanelBinding)ctr;
setBindingContext(ctr.getBindingContext());
public void setBindingContext(BindingContext bindCtx)
if (panelBinding.getPanel() == null)
panelBinding = panelBinding.setup(bindCtx, this);
registerProjectGlobalVariables(bindCtx);
panelBinding.refreshControl();
try
System.out.println("Form setBindingContext calling jbInit");
jbInit();
panelBinding.refreshControl();
// FL added
isBindingContextSet = true;
System.out.println("Form isBindingContextSet true");
catch(Exception ex)
System.out.println("Form setBindingContext exception caught");
panelBinding.reportException(ex);

Jclient Binding to nested application module
we use a test case of
Applications
ParrentAM & NestedAM
Forms
ParrentForm & NestedForm
We added a reference to the NestedAM datacontrol in the ParrentDatabindings.cpx
When the ParrentForm attempts to set the bindingcontext in the NestedForm we recieve a null pointer exception.
Can anyone provide some insite or an example for binding to a nested application module?
thanks.Robert,
what do you mean with "Nested Form", is it a JClient panel that is contained in another JClient panel ?
Which JDeveloper release are you working with? Can you provide me a step by step instruction on how to reproduce your testcase in JClient (assume that I have a Business Component Model that has a MasterApp and a nested NestedApp module, both based on the Scott schema).
thanks for your help

Application module creation failed
Can someone please help me? My data form (which runs fine
through jdeveloper) is failing when I try to run it with an

I've been looking everywhere for help. No luck.
Thank you.
nullHave you included, in the applet tag, all of the archives
specified in the JDev console output when it runs correctly in
JDev?

I checked my business components by creating a default data form using the data form WIZARD. This worked fine and i found that by removing(commenting out) the code associated with the loginDialogueBox(added by wizard) caused the same error to occur with this data form.

Application module creation for (web) services
Hello,
We are running into stack overflows from ADF BC (BC4J) with oracle.jbo.client.Configuration.createRootApplicationModule. We want to make sure we're doing this right.
If you have data bound services (e.g. product lookup) and you don't want to put your operation/exposed method in the application module Impl class for clear seperation (unlike ADF toy store sample), is it appropriate to:
1. Create a Java service class that you will expose as J2EE web service
2. The method to be exposed will call Configuration.createRootApplicationModule to checkout an app module from pool.
3. Find the view object, run the query, get the row.
4. Configuration.releaseRootApplicationModule to check it back in.
Please share your best practices and recommended approach with us.
Thanks,
- ZakI'd recommend using our built-in feature for exposing an application module class as a J2EE web service. This will code-generate a class for you that does the AM access correctly.

JAAS Authorization - Application Module
I created a project based on the BC4J technology. The application module is configured for using the security : jbo.security.enforce=Must. This application module is also configured to deploy the user/password.
When I used this application through a web application, I don't meet any problem.
If I create a POJO class in the same project as BC4J in which I instantiate an instance in the application module pool, I receive the following message :
oracle.jbo.JboException: JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-33021: Failed authenticate user null.
The java class in charge of instantiating the application module pool and get an instance of it works without any problem as soon as the security is not implemented.
Hereafter you can find the method used :
public ApplicationModule getApplicationModule()
try{
PoolMgr poolMgr = PoolMgr.getInstance();
this.lg_ApplPool = poolMgr.findPool( this.lg_configPackage + "." + this.lg_configName, // name of the pool
this.lg_configPackage, // name of the package
this.lg_configName, // name of the configuration
null);
// SessionCookie Creation
String timeStamp = (new java.util.Date()).toString();
// for web application, replace timeStamp by ip address of the client
this.lg_Cookie = lg_ApplPool.createSessionCookie(this.lg_applicationId,timeStamp,null);
CordaEnvInfoProvider lEnvInfoProvider = new CordaEnvInfoProvider ("xxx","xxx");
// this.lg_Cookie = lg_ApplPool.createSessionCookie(this.lg_applicationId,timeStamp,null);
this.lg_Cookie.setEnvInfoProvider(lEnvInfoProvider);
ApplicationModule lAM = this.lg_Cookie.useApplicationModule();
return lAM;
catch(Exception e)
System.out.println("_CrdAppModulePoolMgr - exception : " + e.getMessage());
e.printStackTrace();
return null;
After Having search quite a long time to find a solution, I have no more idea. The only thing I see now is to forget about Jaas if the application module has not to be used by a Java client not being a JClient (Swing) or a Web application.
Could you let me know if
1. jaas works with java client not being Swing or web application
2. if so, could you give me more information about how to work with BC4J application module and security enforce to Must ?
N.B.
POJO Client :
public class TestAppModulePoolMgr
private ApplicationModule lg_Am = null;
private CrdAppModulePoolMgr lgCrdAppModulePoolMgr = null;
private ApplicationPool lg_ApplPool = null;
private SessionCookie lg_Cookie = null;
public TestAppModulePoolMgr()
this.lg_CrdAppModulePoolMgr = _CrdAppModulePoolMgr.getCrdAppModulePoolMgr();
this.lg_CrdAppModulePoolMgr.setApplicationId("CrdGenerationAppModuleId");
this.lg_CrdAppModulePoolMgr.setConfigName("_CrdGenerationAppModuleLocal");
this.lg_CrdAppModulePoolMgr.setConfigPackage("CORDA_BSV");
this.lg_Am = lg_CrdAppModulePoolMgr.getApplicationModule();
this.lg_ApplPool = lg_CrdAppModulePoolMgr.getApplicationPool();
this.lg_Cookie = lg_CrdAppModulePoolMgr.getApplicationSessionCookie();
* @param args
public static void main(String[] args)
TestAppModulePoolMgr testAppModulePoolMgr = new TestAppModulePoolMgr();
}Thank you.
I use SSO authentication to test my application so have no users defined.
Can I use the test-all user? If so, what is the password? -
PL/SQL from Application Module instead of Using VO/EO - Violating Standard?
Hi,
I have seen product code which Use PL/SQL APIs for committing data (Creation of Records in Table) from Application Module. There is no BC4J (VO/EO) used in this data route.
Is there any coding standard (document) which says such cases are against Standards.I know there is one Standard saying PL/SQL Based VO is dicouraged in Oracle Apps.
Thanks
JosephVikram,
Performance depends on the way you are going to make use of pl/sql code. Suppose if you are using pl/sql just for final insert/update with other validations bound to it through a single call, that's fine. But in case you have other multiple calls to pl/sql blocks also for fetching data for display purpose, that's where standard VO's will be more efficient reducing the number of trip for pl/sql calls. So use it only when it is the last way and you need to handle multiple validations with complex data structure.
As for locking, yes, you might have to take care of locking handling scenario if such a situation happens. But again it depends on what's your business logic and how is your data being processed.

BAPI creation versus function module creation...
Hi,
I know the difference between BAPI and simple function module. I have also created custom function module.
But I have not worked on creation of Custom BAPIs.
Is there a much differece in creation of function module and BAPI?
If there is please throw some light on main differences or stepwise differences when I create BAPI versus function module ?
Thanks.
Regards,
Tushar.Hai Tushar
what is BAPI?
BAPI stands for Business API(Application Program Interface).
I have answered this question before..
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
Please check out this thread..
Re: bapi
Also refer to the following links..

Java Connector(JCO) can call not only BAPI's but also the function modules which are remotely enabled..
BAPI's as i said earlier are remotely enabled function modules..
Hence, JCO can call also BAPI's(n not only BAPI's as u mentioned).
Thanks & regards

HOW TO: Connect web service (remote application module) to existing model
Hello.
I have J2EE application which displays some data in an applet, which reads them by a web service. I'd like to use persistence and connect with a web service called by applet to my current model set within a session. I tried to pass a session id to web service (to a function of an application module implementation). I wanted to create a new SessionCookie instance with such a session id and application id which are used for web application session (by ApplicationPoolImpl.createSessionCookie() or with custom session cookie factory). But I don't know how to pass a session and application ids to a sessioncookie creation process (ApplicationPool environment). I tried to use custom EnvInfoProvider, which set my properties, but it passes the params after a SessionCookie instance is created.
Samples ... AppModuleServer - file generated to provide ws functionality. I changed code to use EnvInfoProvider:
public class AppModuleServer extends Object{
public AppModuleServer(){}
public SomeObject[] myCustomFunction(String sessionId){
AppModuleImpl _am = null;
String appId="someValue";
CustomEnvInfoProvider envProvider=new CustomEnvInfoProvider(appId, sessionId);
try{
_am=(AppModuleImpl)Configuration.createRootApplicationModule("data.AppModule", "AppModuleLocal", envProvider);
return _am.myCustomFunction(sSessionId);
finally{
if (_am != null)Configuration.releaseRootApplicationModule(_am, false);
}CustomEnvInfoProvider:
public class CustomEnvInfoProvider implements EnvInfoProvider{
private String applicationId;
private String sessionId;
public CustomEnvInfoProvider(String applicationId, String sessionId){
this.applicationId=applicationId;
this.sessionId=aessionId;
public Object getInfo(String info, Object environment){
if(info==null)return null;
return ((Hashtable)environment).get(info);
public void modifyInitialContext(Object environment){
if(applicationId!=null)((Hashtable)environment).put("CookieApplicationId", applicationId);
if(sessionId!=null)((Hashtable)environment).put("SessionId", sessionId);
public int getNumOfRetries(){
return 2;
}Does anybody knows how to pass information from custom EnvInfoProvider just before a SessionCookie is created (e.g. how to run modifyInitialContext() function). Or another way how to pass these information from a web service base function into ApplicationPoolImpl instance. E.g., there is parameter "properties" whithin a createSessionCookie method of ApplicationPoolImpl, which is null during calling. Is it possible to pass there some additional information?
Thanks for any suggestions.Use the Web Service Proxy wizard in JDeveloper to create a class that calls your Web service, and then call this class from code in your AM.

How many application modules do I have to have ?
Sir,
In my JClient application, there is a model project which contains view objects for two forms. One of the forms is opened witin the other form.
If I include all view objects in one application module, will the two forms share one database session and be committed at the same time?
If I want to open these two forms in different database session, how can I get it?How many application modules should I create? And how to arrange these application modules?
Thanks
StephenFrank,
Now I create two application modules for the two forms in the same model project, and one of the forms has a JCLoginDianlog created, the other one has no JCLoginDialog. And I unselect the deploy password checkbox for the connection.
How can I open the second form within the first form without the second login procedure? I mean, can I keep the first login credential and use it for the second form login?
In Forms Builder, the end user need to login once when opens the main window, and don't need login when opening subcequent forms. Can Jdeveloper do that?
Thanks

Setting v$session.program property in application module config
How can I set the v$session.program property in the AM config, so that when a new connection is created, the v$session.program field is documented with the property value.
I added the following in JClient JCLoginDialog:
((Hashtable)connEnvironment).put("v$session.program", "my program name");
I traced the V$SESSION TABLE:
The added connection has "my program name" in the program field but if I open other application module instances, the new connections have an empty v$session.program field.
I suppose that a property must be added to all application module configurations.
Can somebody help me on this one?
The v$session.program field is helpful when sessions must be killed.
Thanks
FredI don't believe there is a built-in mechanism for that.
But you can easily do it yourself. In you AM class:
public void prepareSession( Session session ) {
super.prepareSession( session );
setDatabaseClientInfo( Bc4jConstants.APPLICATION_NAME );
setDatabaseModuleInfo( moduleInfo );
}And then:
public void setDatabaseClientInfo( String clientInfo ) {
try {
this.getTransaction( ).executeCommand(
"BEGIN dbms_application_info.set_client_info('" + clientInfo + "'); END;" );
} catch( Exception e ) {
// uncritical error
log.warn( "Error setting the database client info: " + clientInfo, e );
}and
public void setDatabaseModuleInfo( String moduleInfo ) {
if( moduleInfo != null ) {
try {
this.getTransaction( ).executeCommand( "BEGIN dbms_application_info.set_module('"
+ moduleInfo + "', NULL); END;" );
} catch( Exception exception ) {
// uncritical error
log.warn( "Error setting the database module info: " + moduleInfo, exception );
}In a similar fashion you can set the client identifier. We use the moduleInfo to identify the module of the session. The client info helps us to identify the application.

Nested Application Module Performance
What are the implications of nesting application modules? I am nesting them in such a way that they are defined at design-time and used by calling findApplicationModule(String) on the root ApplicationModule. Could there be any significant overhead accessing one nested app mod in this way as opposed to going to the desired app mod directly? Or is there anything else to watch out for with this type of design? I haven't had any trouble so far but my project is not too large yet.
For example, I have three ApplicationModule objects.
RootModule, Module1, and Module2. By nesting Module1
and Module2 under RootModule, I can use either once I
have an instance of RootModule by calling
findApplicationModule(String name). This is useful
when I want to do things inside both Module1 and
Module2 and still use the same connection and
transaction context.
If I only want something out of Module1 during a
request, would it be advantageous to ONLY create
Module1 directly and bypass my RootModule?
Meaning this:mod1Am =
Configuration.createRootApplicationModule("Module1","M
dule1Config");
mod1Am.myCustomOperation();As opposed to
this:rootAm =
Configuration.createRootApplicationModule("RootModule"
"RootConfig");
mod1Am = rootAm.findApplicationModule("Module1");
mod1Am.myCustomOperation();
Nick:
There are advantages to creating Module1 directly. It would be that you don't create unnecessary objects (in your case, you would avoid unnecessary creation of Module2").
However, I would make the following side comment: from your message, it sounds like you would create an AM for every request and remove it at the end. Did you consider using AppModule pool? AM pool would be better than create-remove because AM pool can keep around a number of root AM instances and manage resources for you. This way, you don't have to create any AM for each request. AM pool is also able to support stateful operations with excellent scalability.
Thanks.
