Template and application module code sharing

Experts,
I have a template which has some BTF as dynamic regions. Each BTF is based on one App Module. My use case is
Login page - AppModule
Main page
pageFragment1 - AppModule1
pageFragment2 - AppModule2
Successful login takes me to Main Page with Pagefragment1 as the default region. In page Fragment 1 , i am displaying total by exposing a method from AppModulue1 (cant store this in any scope variable as i need to have a ppr from the pageFragment to the main template page).
I want this total to be appearing on the main page also.
How can i do this ?
thnks
Jdev 11.1.2.1

Hi,
this is only possible if the bounded task flows share the DataControl scope in which case adding the AM to the main page also shows the value you see in the bounded task flow. Alternatively, you can pass a JavaBean object defined as a managed bean in the main page to the task flow (as an input parameter), then have the bounded task flow updating the bean reference and use EL in the main page to show the value (addressing the managed bean property)

Best practice for calling application module methods and plsql code

In my application I am experiencing problems with connection pooling, I seem to be using a lot of connections in my application when only a few users are using the system. As part of our application we need to call database procedures for business logic.
Our backing beans, call methods on the application module which in turn call a database procedure. For instance in the backing bean we have code like this to call the application module method.
// Calling Module to generate new examination/test.
CIGAppModuleImpl appMod = (CIGAppModuleImpl)Configuration.createRootApplicationModule("ky.gov.exam.model.CIGAppModule", "CIGAppModuleLocal");
String testId = appMod.createTest( userId, examId, centerId).toString();
AdfFacesContext.getCurrentInstance().getPageFlowScope().put("tid",testId);
// Close the call
System.out.println("Calling releaseRootApplicationModule remove");
Configuration.releaseRootApplicationModule(appMod, true);
System.out.println("Completed releaseRootApplicationModule remove");
return returnResult;
In the application module method we have the following code.
System.out.println("CIGAppModuleImpl: Call the database and use the value from the iterator");
CallableStatement cs = null;
try{
cs = getDBTransaction().createCallableStatement("begin ? := macilap.user_admin.new_test_init(?,?,?); end;", 0);
cs.registerOutParameter(1, Types.NUMERIC);
cs.setString(2, p_userId);
cs.setString(3, p_examId);
cs.setString(4, p_centerId);
cs.executeUpdate();
returnResult=cs.getInt(1);
System.out.println("CIGAppModuleImpl.createTest: Return Result is " + returnResult);
}catch (SQLException se){
throw new JboException(se);
finally {
if (cs != null) {
try {
cs.close();
catch (SQLException s) {
throw new JboException(s);
I have read in one of Steve Muench presentations (Oracle Fusion Applications Team' Best Practises) that calling the createRootApplicationModule method is a bad idea, and to call the method via the binding interface.
I am assuming calling the createRootApplicationModule uses much more resources and database connections that calling the method through the binding interface such as
BindingContainer bindings = getBindings();
OperationBinding ob = bindings.getOperationBinding("customMethod");
Object result = ob.execute()
Is this the case? Also is using getDBTransaction().createCallableStatement the best way of calling database procedures. Would it be better to expose plsql packages as webservices and then call them from the applicationModule. Is this more efficient?
Regards
Orlando

Thanks Shay, this is now working.
I successfully got the binding to the application method in the pagedef.
I used the following code in my backing bean.
package view.backing;
import oracle.binding.BindingContainer;
import oracle.binding.OperationBinding;
public class Testdatabase {
private DCBindingContainer bindingContainer;
public void setBindingContainer (DCBindingContainer bc) {this.bindingContainer = bc;}
public DCBindingContainer getBindingContainer() {return bindingContainer;}
public static String validateUser()
// Calling Module to validate user and return user role details.
System.out.println("Getting Binding Container from Home Backing Bean");
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
System.out.println("Obtain binding");
OperationBinding operationBinding = bindings.getOperationBinding("calldatabase");
System.out.println("Set username parameter");
operationBinding.getParamsMap().put("p_userId",userId);
System.out.println("Set password parameter");
operationBinding.getParamsMap().put("p_testId",examId);
Object result = operationBinding.execute();
System.out.println("Obtain result");
String userRole = result.toString();
System.out.println("Result is "+userRole);
}

Java code common to the applications modules

I need help to generalise some methods and include them in project.
I have some Java methods and I need it to be able to include/calll these methods from different application modules.
I need it accessible to all app modules.
Is there any way to do it?

what we do is create a root application module to be the parent of all our app modules. edit that root app module and add your other app modules as nested app modules under the "Application Modules" section. then in your child app module java code you can initialize your root application module by using the getRootApplicationModule() method:
YourServiceImpl yourServ = (YourServiceImpl)getRootApplicationModule();
then you have access to all your methods in the master app module. however, to make sure you're accessing your app module in the desired hierarchy, you have to base your jhs app def file on your root app module or use your app module under the desired hierarchy in any of your custom adf pages.
hope this helps

Error While Calling a WebService from Application Module

Hi all
I have generated a Proxy from a web Service and i am trying to call the web service from an Application Module it is throwing me error
JBO-29000: Unexpected exception caught: oracle.classloader.util.AnnotatedNoClassDefFoundError, msg= Missing class: webservices.types.com.siebel.xml.order_interface.Orders Dependent class: java.lang.reflect.Array Loader: jre.bootstrap Code-Source: unknown Configuration: jre bootstrap

IMy web Service is correct, as i have executed the client and it is working fine, but when i try to class the web service from an external class or from an application module it is throwing me this error. So any light on this issue will be very helpful
thanks

Hi,
did you registered the web service in the external service registration? The "DataAccessException:" is a hint to this issue.

Problem releasing the application module after upgrade to 11.1.1.2

We have recently upgraded from JDeveloper 11.1.1.1 to 11.1.1.2.
In the "tearDown()" method in our Unit Tests, the Application Module is realeased using:
private ApplicationModule am;
Configuration.releaseRootApplicationModule(am, true);
Alter the upgrade, this produces the following error:
oracle.jbo.JboException: JBO-33025: Failed to release application module MapServiceGlobal. Cookie handle not found.
Please Help.
FYI - this is the code that is used to create the application module:
Hashtable env = new Hashtable(2);
env.put(JboContext.INITIAL_CONTEXT_FACTORY,JboContext.JBO_CONTEXT_FACTORY);
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
try
InitialContext ic = new InitialContext(env);
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(rootAM);
am = home.create();
catch (NamingException nex)
/* Handle the error here if you don't find it */
throw new NamingException("Application Module naming exception " + rootAM + " : " + nex.getMessage());
/* Connect the AM to a database connection */
am.getTransaction().connect(jdbcConnectionURL);
* Set the bundled exception mode so that exceptions are thrown in the
* same way as when we're running in the web application.
am.getTransaction().setBundledExceptionMode(true);
Thanks,

Hi,
I used OCEP 10.3.0.0 and upgraded the wlevs30 domain to PS6(11.1.1.7.0). and it worked without such error.
My experience is:
1) in OCEP 10.3.0.0 it needs not to add the security groups in atnstore.txt
2) you need to add <scratch-directory/> for Jetty in server's config.xml otherwise you will see the visualizer takes a long time to get up on Windows

How do I call an Application Module method from a EntityImpl class?

Guys and Gals,
Using Studio Edition Version 11.1.1.3.0.
I've got a price update form, that when submitted, takes the part numbers and prices in the form and updates the corresponding Parts' price in the Parts table. Anytime this Parts view object's ReplacementPrice attribute is changed, an application module method needs to be called which updates a whole slew of related view objects. I know you can modify view objects via associations (How do I call an Application Module method from a ViewObjectImpl class? but that's not what I'm trying to do. These AppModuleImpl methods are the hub for all price updates, as many different operations may affect related pricing (base price lists, price buckets, etc) and hence, call the updatePartPricing(key) method.
For some reason, the below code does not call / run / activate the application module's method. The AppModuleDataControl exists and recordPartHistory(key) is registered and public. At runtime, the am.<method> code is simply ignored, and as a weird side-effect, I cannot navigate out of my current page flow.
public void setReplacementPrice(Number value)
    setAttributeInternal(REPLACEMENTPRICE, value);
    AppModuleImpl am = (AppModuleImpl)this.getDBTransaction().findApplicationModule("AppModuleDataControl");
    Key key = new Key(new Object[]
        { getPartNumber() });
    am.recordPartHistory(key); // AppModuleImpl method which records pricing history
    am.updatePartPricing(key); // AppModuleImpl method which updates a whole slew of related pricing tables
}Any ideas?

Thanks Timo.
Turns out the code provided was correct, but the AppModuleImpl method being called was not. A dependent ViewObject wasn't returning the row I was expecting. I then tried to perform some operations on that row, which in turn ... just stopped everything, but didn't give me an error.
It was the lack of the error that threw me off. I had never messed with calling an AppModuleImpl method from the EntityImpl so I assumed that's what was messing up.
You are correct. It is available from the ViewRow, but I thought it better to put it in the EntityImpl. This method will be called every time the replacement cost is modified. If I didn't put it in the EntityImpl, I'd have to remember to call it every time a replacement cost changed.

How to configure Application module pooling?

I want to know wheather bc4j container itself manages Application module pooling if yes then please tell me is there any file to set parameters for congiguration like one which we have for apache web server.
If no then please let me know how to create applicatiom module pooling.
Thanks in advance.

Application module pooling is configurable through an application module configuration. In order to edit an application module configuration you may right click an application module and select Configurations...
The BC4J data web beans and the BC4J JSP datatags are both application pool clients. The BC4J documentation includes descriptions of the application pool properties. The documentation also includes a code sample which illustrates how to write your own pool client.

The Application Module conatians an entity object and a view object for Dept Table in schema jd(Username -jd, Password -jd).

Moneesh,
I believe there is a problem with the way you set the variable theAMDefName. It should be:
String theAMDefName = freshJBO.FreshJBOModule";
Then you need to reinstate the line you commented out, to set the application path (but remove the trailing / from the path, as shown):
env.put(JboContext.APPLICATION_PATH, "test/jd");
If that doesn't work, and for future reference, I suggest testing your deployed application module from the Business Component Browser (aka the tester) before trying your hand-coded client. Start the tester, select Oracle8i as the middle tier server type, make sure the other information in the connect window is correct, then click Connect.
Good luck

How to programmatically call remote application module - JDev 10.1.3.3.0

Hi,
I've an ADF web application (10.1.3.3.0) deployed onto an OAS server. I'd like to be able to access view objects via the application module of this web app from a simple java class on another server.
I've created a simple class to query a local application module (included in the same project as the simple class). This works fine but I'm not sure how to change this to access an application module when it's remote on another server. Can anyone assist?
Here is my sample code for querying a local application module/view object:
    public static void main(String[] args) {
        ApplicationModule applicationModule =
            Configuration.createRootApplicationModule("com.almac.model.common",
                                                      "AppModuleLocal");
        try {
            ViewObject eventList = applicationModule.findViewObject("SipEventsView1");
            eventList.executeQuery();
            while (eventList.hasNext()) {
                Row event = eventList.next();
                System.out.println("Event Name: " + event.getAttribute("EveName"));
        } catch (JboException e) {
            System.out.println(e.getMessage());
        } finally {
            Configuration.releaseRootApplicationModule(applicationModule, true);
    }Thanks,
Paul.

You can expose an AM as an EJB or Web service to expose them for remote access:
