Error: demo.model.AppModule: Application module demo.model.AppModule has a view instance EmpByEmail1 that references an invalid view object.
intially i created view object named EmpByEmail.........for that EmpByEmail1 is created in datacontrols....i deleted EmpByEmail in demo.model by mistake and i created again with same name EmpBYEmail another view object...again another EmpByEmail2 is created in datacontrols.....
while i am running i am getting following error:::::::
Error: demo.model.AppModule: Application module demo.model.AppModule has a view instance EmpByEmail1 that references an invalid view object.

Hi,
Please seasrch for the EmpByEmail1 file in ur project and remove all the details in the Page Def and UI and then try again.
Due to the EmpByEmail1 existance in page Def this may occur . It may help , still if it was not working then I am sorry for that.

Dynamic VO error while testing without Application Module Pooling

Hi,
I am using ADF11g 11.1.1.4
I have a dynamic VO which is used to display data depending on user defined configuration .
It works fine till I try to test the application for activation / passivation by disabling application Module
The moment I do this the application starts throwing ArrayIndexOutOfBound exception with the following trace.

Hi Frank,
The view object is an Entity based view object with a very simple where clause
We have a train flow and each stop is a jsf page which renders the dynamic VO
Each pages have a simple iterator for View object related to the stop to create a form iterating over the View object attributes.
We tried to investigate the problem by making a train for two stops with two dynamic VO, one on each stop , this was done as a train which had only one stop as dymanic VO worked fine.
We found the problem to be that when passivation was being called on change of train stop1 to train stop 2,
Application module was passivting all the view objects and it was trying to find attributes of view object2 , which is attached to train stop 2, while being at train stop 1 and it was not able to find the attribute definition on train stop 1.
Strangely it was able to find the view object 2 definition but not the attributes of the view object 2, even when there was no binding in the page def for the view object Iterator 2.
To solve , We created a iterators for view objects on both the pages and rendered the one not related to the stop be false and It then solved the problem
But I am not very comfortable with the solution as I am not very sure how does an Iterator binding on the jsff page , set to rendered false help in passivation.

How to access application module from ActionForm Execute?

I've got a very simple ADF/UIX/Struts application where I'm trying to create a simple Login function. I have a /loginAction data action pointing to a login.uix page forward. The login.uix page has a <struts:form> on it with a user and a password field. There is a LoginBean with the corresponding get/set values. I have an ADF model created with a boolean login(String username, String password) function exposed as a client method.
Eventually, when I have this basic part working, then I'll actually be using an ActionForward mapping to dispatch to different home pages, based on the particular login account (the name of the forward will be stored in the authentication table).
I've tried overriding Execute(), since that is where you can return the appropriate ActionForward mapping, but that does not have a DataActionContext passed in -- so I can't get to the application module.
I've also looked at processComponentEvents, but that doesn't have any ActionForward results nor a way to pass back ActionErrors (in case the login fails).
How do I call my login client method when a user has entered a username/password and pressed the Submit button?

Here is another solution as provided by Oracle Support in response to a TAR that I opened:
I had described my need to access a login() function defined in my Application Module, returning true/false if the login succeeds/fails. Here is the reply, posted with permission:
I have gotten the following information back from one of the development folks pertaining to the question you asked.
His suggestions are as follows:
1) Expose the method as a client method on the App module
2) On the pageflow create a new DataAction
3) Drag and drop the logon method from the AppModule operations node and drop it onto the new data Action
3) Edit the set-property values that are created in the Struts metadata for this new DataAction to use the correct expressions to get the logon info to pass to the middle tier.
e.g.
<action path="/authenticateUser" className="oracle.adf.controller.struts.actions.DataActionMapping" type="AuthenticateUserAction" name="DataForm"
unknown="false">
<set-property property="modelReference" value="authenticateUserUIModel"/>
<set-property property="methodName" value="authenticateUserUIModel.authenticateUser"/>
<set-property property="resultLocation" value="${requestScope.methodResult}"/>
<set-property property="numParams" value="2"/>
<set-property property="paramNames[0]" value="${param.logonUsername}"/>
<set-property property="paramNames[1]" value="${param.logonPassword}"/>
<forward name="fail" path="/logon.do"/>
<forward name="success" path="/menu.do"/>
</action>
So in this case the values of the logonUsername and logonPassword fields in the form that submitted to this DataAction are passed as the two parameters that my authenticateUser method on the AppModule requires.
I have also overriden the data action class to customise the findForward() method to route the user depending on if the method call worked or not.
And here's the code for the customized FindForward in the DataAction:
protected void findForward(DataActionContext actionContext) throws Exception
HttpServletRequest request = actionContext.getHttpServletRequest();
HttpSession session = request.getSession();
String target = "fail";
//Get the result of the Model Method call
JUCtrlActionBinding method = actionContext.getCustomMethod();
boolean successfulLogon = ((Boolean)method.getResult()).booleanValue();
if (!successfulLogon)
// If the logon fails we need to do the following
// 1. Increament the counter once this exceeds 3 any logon will fail
// 2. Create an error message to display on the logon screen
// note this is a non specific error to prevent hackers from
// knowing that they at least got the username right or from
// knowing that there is a Max attempts value if they are trying
// an automated attack
Integer attempts = (Integer)session.getAttribute("logonAttempts");
int intAttempts = 0;
if (attempts != null)
intAttempts = attempts.intValue();
session.setAttribute("logonAttempts", new Integer(++intAttempts));
//The error message comes out of the ApplicationResources.properties file.
actionContext.getActionErrors().add("general",new ActionError("logon.error.logonFailed"));
this.saveErrors(actionContext.getHttpServletRequest(),
actionContext.getActionErrors());
else
//If connection was OK do we need to save the username in a cookie?
String remember = (String)request.getParameter("logonRemember");
int cookieLife = 0; //Expire
if ( remember != null && remember.length()>0 )
cookieLife = 2592000;
String name = (String)request.getParameter("logonUsername");
Cookie userCookie = new Cookie("CARA_USER_COOKIE",name);
userCookie.setMaxAge(cookieLife);
actionContext.getHttpServletResponse().addCookie(userCookie);
target = "success";
actionContext.setActionForward(target);
I hope this helps anyone looking to implement something similar. It also illustrates the "preferred" way of executing a client method and working with the result.

also the same as the error: could not load application module
there is something with association links, u should remove links and then reMake the EO and attach the VO with it (reMaking built the associations and links again so when removing the links and reMaking then the EO will not anymore contain the wrong link)

Best Practice - Bounded Task Flows, Regions and Nested Application Modules

Using JDev 11.1.1.3; understand that it's generally considered good practice to just have 1 root application module servicing model content / services for each page. In our application, we've used a number of bounded task flows and page fragments deployed as af:region's into pages as either a) views targeted in page-flow navigation, b) tab panel content inside a regular jspx, or c) af:popup / af:dialog content. As it stands, we've not engaged nesting of the application modules for this embedded region content, so these regions are no doubt instantiating new AM's if/when invoked. Should the AM's servicing these embedded regions be deployed nested within the root AM's, and then if so, does this change the way that the jsff / fragment content is actually developed (currently as per any other jspx using the DataControl pallete). Or are the best-practice directives talking about a page as being the design-time / declarative composition of content rather than the run-time aggregation of page + fragments ... in which case the fact that our embedded fragments are not using nested AM's is unlikely to concern.
Thanks,

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.

Could not load application module 'oracle.apps.pos.supplier.server.SuppSumm

hi
when i create supplier in AP Super user,the supplier entry page got error:
Could not load application module 'oracle.apps.pos.supplier.server.SuppSummAM',is there anyboay could help me? thanks a lot!
metalink's solution is:
-- To implement the solution, please execute the following steps::
1. Using System Administrator Responsibility.
2. Navigate to Profiles > System.
3. Query for the Responsibility used and for Profile: MO: Operating Unit.
4. Kindly check the value attached to the security profile: MO: Operating Unit.
5. If security profile is not set, attach a value to it.
6. Delete the Browser and Apache Cache. Restart the Apache.
7. Re-test the issue again.
but it didn't work!

Did you ever figure this out? I'm encountering the same issue.
Thanks.

JSP application module releasemodule

I encounter some problems in my JSP pages. When I start my server the first time everything works fine, but when I visit some other pages sometimes I got this error without any reason:
Application Error
Return
Error Message: null
I think it has something to do with the releasemode of the application module. Some pages has the releasemode set to statefull because I have to pass a whole rowset to the next page. Can I pass a whole rowset to the next page with releasemode set to stateless??
Another thing that looks strange to me is that the rowset you selected is saved in the viewobject and not in the datasource. Even if you have 2 datasources with different names on the same viewobject you will always see the same rowset.
If you make a query page and you get some resultrows from your search and then make a second page with just a browse structure. You will see in this browse page only the rows from the query of the previous page and not all the rows in the table, even if I write this <jbo:RefreshDataSource datasource="ds" />
How is this possible, it seems to me that the RefreshDataSource tag is not working!!!
So how can I refresh a datasource so that I can see all the rows of the table again????
thanx,
Lieven

I have made these 2 test pages. When I make a search in test1.jsp and so get a part of the table as resultset and then go the test2.jsp I only see that part of the table in test2.jsp. What do I have to change or which function do I have to call to see the whole table in test2.jsp??? Changing the releasemode is not a solution because it has to stay on statefull for another part of my website.

Release Application Module

Guys,
I couldn't understand the exact difference between
Configuration.releaseRootApplicationModule(am, true);
and
Configuration.releaseRootApplicationModule(am, false);
1. True -> AM instance will be deleted???
2. False -> AM intance will not be deleted and when i do am = Configuration.createRootApplicationModule(amDef, config) , i will get the same am instance?
Can you guys help?

Straight from the docs:
releaseRootApplicationModulepublic static void releaseRootApplicationModule(ApplicationModule appModule,
boolean remove)
Release the specified application module.
Parameters:
appModule - an application module which was created with createRootApplicationModule(String, String, EnvInfoProvider)
remove - indicates whether the application module should be removed true: remove the application module false: retain the application module for future use
>
BUT read this http://radio-weblogs.com/0118231/2009/08/20.html#a959 and ask yourself why using createRootApplicationModule in the first place.

Single session for all Application Modules

Hello,
I've got an application that has several Application Modules. All these modules need some data that are set from time to time. I've written some code that calls getSession().getUserData().put("myData",myData). After this method was called in another Application Module i want to retrieve myData with getSession().getUserData().get("myData"). But the result depends if I use 2-tier or 3-tier. In 2-tie I get myData while in 3-tier I get null. My question is:
Is there a Session object or any other data instance that could be accessed from all Application Modules for on application instance.
E.g. I've got two user (A,B) who start my application. Through using my app several instance of Application Modules are created. All Application Modules that are created for the instance of User A should be able to share his user name and some other dynamic data while the Application Modules created for B should have no access to that data.
Doe anybody know if static data of an Application Module are a possible solution?
regards
Joerg

Hi Joerg,
I am not 100% sure what you are trying to achieve, and with which version of JDeveloper/ ADF, technologies (JSP, Swing), etc, but I can tell you that I have been experimenting with single session accounts myself within a rich-client Swing environment, as I have experienced Oracle DBA guys who want to control user authentication via Oracle accounts (I have achieved this via the JCLoginDialog mechanism, and a bit of a hack)... Frank Nemphius (sp?) posted something about a white paper coming out on a related subject but I don't know where he is with that.
Anyway, I managed to do it in a prototype by nesting several application modules within a Root Application Module that was essentially simply a Container for the other application modules. Using this mechanism I was able to bind my root application module to any panel I wanted and it would inherit the roots Session.
ie. I used many application modules and it only used one Oracle Session.
However, my reservations -
1) This solution was not tested robustly!
2) I doubt this would be ideal for a distributed app with thousands of users - My solution is for a very complex app, with a limited number of users.
Finally, I cannot confirm this is a great solution - I can only tell you it worked in my prototype, and I am currently awaiting the ADF source - when my company and Oracle can decide what level of support we currently have and need!?!? - what exactly does being an "Oracle partner" mean??? Its all very boring and un-interesting to a Java person like me... ;-)
Once I have the source I will look at how it actually works and perhaps be able to answer questions like this more definitively. Hmm - I wonder if I could get the Oracle JDBC driver source too?? .... Is it written in C or C++?? I know them too... ;-)
Cheers........Dean

Sharing view objects across application modules

Our application uses multiple application modules because of the complex functional requirements. We have come across sharing view objects among application modules. I want to understand the best practice, sharing view object instances across application modules. These view objects can be based on Entity Objects also.
Please let me know if there any suggestions.
Thanks,
Satya

Hi Satya,
You won't be able to share view objects between application modules, but what you can do is to share the bind variables between application modules, if each of your module contains the 'common' view object.
A solution for sharing data between application modules is provided on this blog: http://andrejusb.blogspot.co.uk/2012/05/solution-for-sharing-global-user-data.html
You can use this approach to share bind variables between AM's and re-query the same data.
Hope this helps,
