Application Module Issue

We are experiencing an issue when using multiple Java Restful web services on our development Oracle Weblogic. Each of these services uses ADF BC for DB interaction. The test case scenario is Web service A does some database work via ADF BC and then calls Web service B which also interacts with the DB. Both of these services are hosted on the same managed server instance within Weblogic, The error we are experiencing is as follows (I can post full stack trace if requested):
java.lang.ClassCastException: oracle.jbo.common.DefLocaleContext cannot be cast to oracle.jbo.common.DefLocaleContext                at oracle.jbo.common.DefLocaleContext.getInstance(DefLocaleContext.java:84)
Debugging our code we can see that the following line of code (highlighted in bold) is where the error is thrown.
            String amDef = "package.AppMod";
            String config = " AppModLocal";
            ApplicationModule am = null;
            am = Configuration.createRootApplicationModule(amDef, config); //Error Here
The bizarre thing is that it seems almost random in which of the service the error will be thrown. It never occurs on the first run after a deploy to the server, but will occur on subsequent runs. We correctly use the following line in each of our service to release the application module:
           Configuration.releaseRootApplicationModule(am, true);
We have tried including adfBinding filters in our web.xml but still with no success.
Details of our setup follow:
Application Server: Oracle Weblogic Server 10.3.6, JDK 1.7.0.21, JSF 2.0, ADF Runtime 11.1.2.4
Database: 11 R2 - 11.2.0.3
JDeveloper: 11.1.2.4
Any assistance would be greatly appreciated.

Hi User,
out of sheer curiosity. Are you really using ADF 11.1.1.6 and JDeveloper 11.1.2.4 together? How does that work?
Regards,
Linda

Root Application Module issue

We use JDev Build JDEVADF_11.1.1.5.0_GENERIC_110409.0025.6013.
We have a scenario as follows
Model
1. We have a nested AM scenario which contains 2 view instances of the same View Object (EmployeeView) in the nested AM
View
1. URL Invokable Bounded Taskflow containing just one JSPX with transaction set as "Always Begin New Transaction - Not Sharing Data Controls"
2. Bounded Taskflow with JSFF with transaction set as "Use Existing Transaction If Possible - Sharing Data Controls"
3. (2) is dropped as a region in the Page in context of (1)
4. The JSPX page contains a Form intended to display details for EmpId = 105 along with (3)
5. The JSFF referenced in (2) contains another form intended to display details for EmpId = 185
Because, there are 2 different view instances in the RootAM > NestedAM of the same view object EmployeeView,
Expected Behaviour
1. JSPX page should display details for EmpId = 105
2. JSFF Region should display details for EmpId = 185
Noticed Behaviour (Buggy)
Both display details for EmpId = 100 (First Record in the table)
What are we missing here?
Sample demo app. (HR schema) demonstrating the issue

I can see this working in 11.1.2.1.0. However same failed for the version you mentioned.

ADF Libary Issue - Application Module disappear from data control

Hi All,
I am facing an issue while adding an Application module to an ADF project as an ADF libray.
I have two applications - ADF Application1 with Model1 project having an Application module AM1, ADF Application2 with Model2 project having an Application Module AM2
I have created an ADF library jar file of Model1 project.
When I add it to Model2 project, the Application Module AM2 of Model2 disappears and Application Module AM1 from the library appears in data control.
Please suggest what could be wrong.
Regards,
Rekha

Hi,
verify that both application modules don't share the same ID in their databindings.cpx file. Which release version of JDeveloper 11g are you on ?

(IMP)application module and DB connection issue

Hi,
In my BC4J application, Application module is not releasing DB connection after the execution of the JSP page. It usually takes approx 3500-4000sec. to release it. On what parameters this time is dependent??
I am using data-source to connect to DB. Application Module configurations parameters are set with default values.
If i select "Disconnect Application Module Upon Release" from the configuration of Application module, it releases DBconnection at the end of http Request. Is it a proper solution to the issue ? any performance related issues with it?
My JSP code's basic structure is
try
<jbo:ApplicationModule id="<AM ID>" definition="<Fully qualified AM classname>" releasemode="Stateless/stateFul" />
// application code
catch(Exception e)
// Code to take necessary action if exception occurs
finally
<jbo:ReleasePageResources appid="<AM ID>" releasemode="Stateless/StateFul"/>
Please guide me on this.
Thanks in advance,
Devang

Hi john,
Thanks for your reply... in other way can i restrict the number of connections created for the application module By selecting the Disconnect Application Module Upon Release in application module configuration.
If i select that check box in Appmodule-->configurations->Edit->Pooling and Scalability means, while loading my screen number of connections are increased after completion of loading a screen immediatly connections also got reduced. if i select this check box whether it will give any other problems.
Here am using the uishell dynamic tab after opening more number of tabs am getting connection pool error.not allways.. thats why am trying to restrict the no.of connections opening.
please can you provide some info regarding this

Issue in Application Module and Enterprise Integration for SAP applications

Hi,
When I enabled the Application Module and Enterprise Integration for SAP applications Version 2.60 Patch 2 I am getting error in defect entity and Application Module. Does any one face this issue? Please let me know the solution.
QC details: QC 11.0 with patch 7
I followed the steps given in ALM addin page to install the adapters
Attached Screen shots of the Error

Hi
If you are wanting to know how to configure ESSO to be used to logon to SAP applications then there is a guide in the helpfile of the admin console. Simply do a search for SAP.
In short ESSO-LM comes with a SAP helper object which needs to be selected on install. To enable the ESSO SAP helper to interact with SAP, the SAP server and the SAPGUI client need to be configured. The details for this are in the helpfile. If you have multiple SAP systems launched from the SAPGUI then this is the best method because it means ESSO can distinguish between the different SAP systems through matching screens
If you have only one SAP system and you do not want to configure the SAP server then you could use send keys and not use the SAP helper object at all.
Hope this helps

Error While Calling a WebService from Application Module

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

Application module with no connection to the database in jdeveloper 10.1.3

I have a number of programmatic bc view objects and entity objects which i have implemented through the time from different projects and now that i have collected them i want to add all of them in a reusable application module. However i don't need a connection to the database for this application module. Is it possible to enforce the application module to circumvent the db connection?

Hi user,
Just out of curiosity, why would you use ADF BC for that - if I had a bunch of non-db data sources, I'd probably use POJOs and create POJO data controls.
I didn't look in 10g, but in 11g, the ApplicationModule has a method called getDBConnectionRequired() that you could override to see if that solves your issue.

Generated getter in Application Module impl overrides superclass getter

Hi,
I today came across this issue:
* Created an application module where the data model contains a view object named "Parent" (resulting form a parent-child relationship)
=> Application runs perfectly.
* Created an application module implementation class (just created it, no further code added)
=> Application throws java.lang.NullPointerException at oracle.adf.model.binding.DCIteratorBinding.executeQueryIfNeeded(DCIteratorBinding.java:2164)
After some debugging, it turned out that the issue is that JDeveloper created the following getter in the application module impl class:
public ViewObjectImpl getParent() {
return (ViewObjectImpl)findViewObject("Parent");
which overrides public NamedObjectImpl getParent() from NamedObjectImpl, which is a superclass of ApplicationModuleImpl, due to the method's covariant return type.
JDeveloper does not give me any warning or error, not while creating the impl class nor highlighted in the source code.
Actually this would mean that I must manually assure that I never ever name a view object the same as any getter method in any of the ApplicationModuleImpl super classes which have a return type which is covariant to ViewObjectImpl. getParent() is one example, another is getProperty(). Even if it might be unlikely, this adds a potential source for some subtle issues.
Is this known behavior of JDeveloper? Did I miss anything?
Thanks,
Andreas

Hi Frank,
I agree that naming conventions can avoid this type of issue. Nevertheless, as a matter of usability and reliability, I think it would be good if JDeveloper at least gives a warning during code generation when it generates methods which would override a method from a superclass.
In any case, I have logged a bug, lets see how it evolves...
Thanks,
Andreas

Table QBE-Filter BUG in combination with Application Module Pooling ?

Hi,
i use JDEVADF_11.1.1.1.0_GENERIC_090615.0017.5407, Java 1.6.0_14, ADF BC and ADF Faces.
I have one View Object, one Page with a panelCollection and a table with option filtering (create via drag-and-drop from datacontrol).
When I disable the application module pooling on the AM configuration and run the application, i can execute the query-by-example filter, but when I delete the filterCriteria and press enter (requerry for select all) the table shows the old data.
Image for setting on application module:
http://img265.imageshack.us/img265/1374/filterdoesnotwork1.png
Image for execute querry and requerry for "all rows" (deleted filterCriteria)
http://img140.imageshack.us/img140/1963/filterdoesnotwork2.png
When I enable application module pooling all works fine. Is this a issue?
kind regards

Hi Frank,
if I filter for employees which firstname starts with "D" and then for employees with "F" --> i see "No data to display.".
So uncheck "Enable Application Module Pooling" on application module doesn't work with QBE-Filter ?
I can send a testcase but it is so simple you can create it with jdeveloper in 2 minutes ;)

Deployment of OA Project in R12.2 - Could not load application module

I have deployed a project that is working without issue in JDeveloper to a R12.2 environment, but I am receiving the following error on loading of the page. This seems to be a common problem as I have another issue with deploying OA Framework projects in R12.2 Is anyone else using R12.2 or has seen this in any other R12 instance? Anything developed in 11.5.10 first and "upgraded" to the latest JDeveloper is working fine, but so far nothing developed directly in R12.2 JDeveloper works in the environment.

Try bouncing your server and then test it again.Generally this error comes due to uncompiled jsp files.Bounce Apache Server and then check.
You may check Metalink Note: 465812.1

Flex Module issue with Panel

Hello everyone. I have the following problem.
In my application I have several modules and each of them have components CollapsableTitleWindow (extends Panel). After opening the window it is added to the container which is in the main application (CollapsableTitleWindowContainer). In these windows you can open another window (and so on).
Now, what is the problem. When I change (reload) any module and I want to open a new window (sub window) with the already loaded window I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.containers::Panel/layoutChrome()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\containers\Panel.as:1405]

Please help.
P.S. I found a similar problem on http://www.nabble.com/Flex-Module-issue-with-Panel-td20168053.html
ADDED: I extendes the Panel class and do something like that:
override protected function layoutChrome(unscaledWidth:Number, unscaledHeight:Number):void
                use namespace mx_internal;
                if(!(mx_internal::titleBarBackground is TitleBackground)) {
                        mx_internal::titleBarBackground = new TitleBackground();
                super.layoutChrome(unscaledWidth, unscaledHeight);
But now i had something like that: Before After
You can see that it loos style declaration.H

Thanks for the anserw.
I don't exacly understand all but i found a solution for my problem and it works.
Could you tell me if this is ok ?
I Add in my main app
public function getProductWindow():ProductWindow {
    return new ProductWindow();
And in the module i change
From var productWindow:ProductWindow = new ProductWindow();
To var productWindow:ProductWindow = Application.application.getProductWindow();

I am a consumer of the Application module, I have not created it. I am using it by referencing it through the jar file provided by the owner.

Sidd,
No idea what OraTst is, but based upon the name of your data source, I'd guess you are an Oracle employee using an internal framework. I understand that there are some internal Oracle forums that you can use.

Guidelines for setting Application Module Pool Size Parameters?

Are there guidelines for setting the application module pool size parameters, such as initial pool size, maximum pool size, etc., based on the expected number of users or other factors? I've read the developer guide sections (ch 28-29), but still don't have a good feel for how to correctly set the optimal values for the pool configuration parameters? Even more importanty, how do I monitor the pool's efficiency during runtime to determine if the pooling parameters are configured correctly?
This will be critical to performance and scalability, so I'm looking for a way to get some visibility into how the pooling is working during production operation to assess whether there are bottlenecks/constraints/ineffeciencies?
Note I am using Tomcat as the java runtime container; ADF BC / JSF jdev 10.1.3.1
Thanks in advance and Merry Christmas!

KUBA - were you able to resolve these issues and if so are there any lessons learned you can share?
I'm hoping someone from the ADF team can answer our original question including guidelines for setting pool parameters and how to monitor the pool's performance while running in production.
thanks

Nested Application Module - commit behavior

Guys,
I have ADF BC in the following hierarchial manner.
AM1
-VO1
-VO2
-AM2 (nested AM)
Assume that there are pending transactions on both AM1 and AM2.
what is the behaviour for the follwing?
Q1 . Issuing commit on AM1, will it commit AM2 also?
Q2 . Issuing commit on AM2, will it alone commit?
Edited by: Dev on Apr 19, 2011 12:00 PM

ADF distinguish between root application module and nested application modules. A root app module has no parent whereas an nested app module has a parent. A root app module holds the transaction (and only the root app module). Nested app module share the transaction of the root app module (they are nested in).
So Q1: yes and Q2: no.
