Cannot Access Application Module from View Project (Swing)
I recently started a new application workspace as a Swing project with Business Components. Jdev created 2 projects by default, a Model and a View. The model works fine, all the business components are funtctioning and the DB connection is good. When i try to create a reference to the application module in my View project i constantly get 'Class Not Found' exceptions no matter what i do. I am using the jbo.client.Configuration.getRootApplicationModule('amName', 'amConfig') method.
What am i missing? How do i instantiate my application module from my View project?
Thanks a lot.
Just had to add the Model to the classpath...

Referring Application Module from different Project
I have two projects. a.jpr and b.jpr
I need to refer an Application Module from b.jpr in the first project a.jpr
In the Application Module edit Wizard, in the "available" list it shows all the Application Modules from the current project only.
What do I have to do to see the Application Modules of the other project.
In the "Project Settings" option, under "Dependencies" I have referred to the other project "b.jpr"
But it didn't help.
Any help is greatly appreciated.I have a similar problem as follows.
I have two projects: a web WAR and an EJB3 EAR. On deployment all the EJB class files are generated into the WAR file and the contents of the EAR file only has the XML configuration and dependant jar files.
How can I build the deployment EAR with the EJB classes within the jar? Why are they ending up in with the WAR WEB-INF/classes directory?
This a significant problem and any help / advice would be appreciated. -
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. -

Adding and Calling custom method to the application module or view object
My project uses jheadstart 10.1.2.
I want to run "oracle reports" from my uix page. I have coded a method which takes "VOParameter view object" as a parameter to run report.
I have generated the input page (parameter page) which based on VOParameter view object, by using jheadstart for using jheadstart lov, date etc. advantages. But I dont know how can I add custom method on application module or view object implementation class and custom button on uix page to call from uix page.
THANKS for your helpYes, method binding has been added to the page UI model.
I have find some clue that When I darg and drop metod as a submitButton, the code "
<SubmitButton text="runReport" model="${bindings.runReport}" id="runReport0" event="action" />"
is added to the uix page code. I change this code like this;
<button text="runReport" model="${bindings.runReport}" id="runReport0" event="action" onClick="submitForm('dataForm',1,{'event':'action','source':'runReport0'});return false"/>
by adding onClick method and changed submitButton to button tag..
Then button action is triggered. But I can not pass to the design part of the uix page. It gives me the message like that "The document is not a valid state" But it works. I dont know why? -
Howto stop the application module from using a DB
Hello,
Maybe and unusual question, but is there a way to stop the application module from connect to a DB? I know its purpose is to do so. But currently we are using ‘stub’ views and entities.
In the executequery and dodml we wrote our own code to access data from webservices.
We did this because we are also using JHeadStart which requires BC.
It all works fine, but the application module needs a valid connection to a DB, although it will never query anything there.
So is there a method which I can overwrite to make the application module think its connected to the DB but it actually isn’t?
A second problem is most likely its state table.
AntonExample #96 on my blog does this. It might have some useful clues.

if you don't have a binding the I am not sure the binding context is created. Anyway, try
BindingContext.getCurrent().findDataControl("name here as ID in DataBindings.cpx") and see if it returns a valid instance

The difference in calling an application module from a backing bean
Hello everybody!
I don't understand exactly, where is the difference in calling an application module from a backing bean in the following ways.
Example 1
FacesContext context = FacesContext.getCurrentInstance();
ValueBinding vb = context.getApplication().createValueBinding("#{data}");
BindingContext bc = (BindingContext)vb.getValue(context);
DCDataControl dc = bc.findDataControl("AppModuleDataControl");
AppModuleImpl appModule = (AppModuleImpl)dc.getDataProvider();Example 2
String amDef = "model.services.AppModule";
String config = "AppModuleLocal";
AppModuleImpl appModule = (AppModuleImpl)Configuration.createRootApplicationModule(amDef, config);Example 3 (the same like Example 1???)
String EL = "#{data.AppModuleDataControl.dataProvider}";
FacesContext fc = FacesContext.getCurrentInstance();
ValueBinding vb = fc.getApplication().createValueBinding(EL);
AppModuleImpl appModule = (AppModuleImpl)vb.getValue(fc);Please can anybody explain, what the three examples do? Which example is preferred to call an application-module-method from a backing bean?
Thanks and regards
Majo
Edit: I am using ADF BC 10g in JDev10 :)Hi :)
>
This could work, but can you describe the use case for which you need to get the ApplicationModule?
Maybe we can find a better way to implement your functionality.

Sure, i know a lot of better ways to implement the same functionality too but its a huge project, its not my code and we have no time to reimplement this functions ;)
Frank, i don't understand the first line of your code.
DCBindingContainer bindings = ... resolve #{bindings}Where do i get the bindingContainer, if I don't have the "JSFUtils"- or "ADFUtils"-classes?
Regards

Edit:
Sorry, i have answer, before i think about it ;)
FacesContext context = FacesContext.getCurrentInstance();
Application app = context.getApplication();
DCBindingContainer bindings = (DCBindingContainer)app.getVariableResolver().resolveVariable(context, "bindings");
BindingContext bctx = bindings.getBindingContext();
DCDataControl dc = bctx.findDataControl("AppModuleDataControl");
AppModuleImpl am = (AppModuleImpl)dc.getDataProvider();or in my backing bean, when i add the property to the faces-config.xml
DCBindingContainer bindings = this.getBindings();
BindingContext bctx = bindings.getBindingContext();
DCDataControl dc = bctx.findDataControl("AppModuleDataControl");
AppModuleImpl am = (AppModuleImpl)dc.getDataProvider();Is this right? -
How to call application module from ServletContextListener
Hi,
I've got an application that requires authenticated users. However, before the application starts I'd like to do some DB initialization.
So I created a ServletContextListener and in contextInitialized method I try to createRootApplicationModule.
Due to authentication / authorization requirements, createRootApplicationModule fails with:

Can I somehow explicitly login a valid user or exclude the specific application module from authorization?
Regards
JHi,
no, the function is not related to user session. It's actually data synchronization between two systems.
We'd prefere to keep it in middle tier, through web services on one side and AM on the other. This way we are platform / RDBMS independent.
I could use a fake system user, eg. "sync" with password "sysnc", but how do I "log on" such user in my EJB code? If I could somehow access AM login context and call login with username and password...?
Edit:
it also puzzles me that it's possible to have a page within the aplication that allows anonymous access. The only difference in security context seem to be _isHttp property. getUserPrincipaly returns JpsAnonymousUserImpl in both cases, IsAuthenticated() is false in both cases...

Cannot build form off from view?
Is this true because when I try to Add a Page to a new application I dont seem to be able to see any of my views on the list of values but my tables. Opened up a TAR and here was the response
To implement the solution, please execute the following steps:
Use workaround listed in Bug 4719289 - CANNOT BUILD FORM OFF FROM VIEW
1. Create Application
2. Give Application a name, the "From Scratch" option is selected, our
desired
schema is selected.
3. Add Blank Page, select theme, etc, application is created.
4. From Blank page, Add Form Region based on existing table, followed the
resulting steps in the Wizard, etc.Please share your first name and put it into your profile to help us.
You can create a form based on ("off from") a view after an application is created using the create page or create region wizards.

How to invoke a method in application module or view objects interface?
Hi,
perhaps a stupid RTFM question, but
How can i invoke a method that i have published in the application modules or view objects interfaces using uiXml with BC4J?
Only found something how to invoke a static method (<ctrl:method class="..." method="..." />) but not how to call a method with or without parameters in AM or VO directly with a uix-element.
Thanks in advance, MarkusThanks for your help Andy, but i do not understand why this has to be that complicated.
Why shall i write a eventhandler for a simple call of a AM or VO method? That splatters the functionality over 3 files (BC4J, UIX, handler). Feature Request ;-)?
I found a simple solution using reflection that can be used at least for parameterless methods:
<event name="anEvent">
<bc4j:findRootAppModule name="MyAppModule">
<!-- Call MyAppModule.myMethod() procedure. -->
<bc4j:setPageProperty name="MethodName" value="myMethod"/>
<ctrl:method class="UixHelper"
method="invokeApplicationModuleMethod"/>
</bc4j:findRootAppModule>
</event>The UixHelper method:
public static EventResult invokeApplicationModuleMethod( BajaContext context,
Page page,
PageEvent event ) {
String methodName = page.getProperty( "MethodName" );
ApplicationModule am = ServletBindingUtils.getApplicationModule( context );
Method method = null;
try {
method = am.getClass( ).getDeclaredMethod( methodName, null );
} catch( NoSuchMethodException e ) {
RuntimeException re = new RuntimeException( e );
throw re;
try {
method.invoke( am, null );
} catch( InvocationTargetException e ) {
RuntimeException re = new RuntimeException( e );
throw re;
} catch( IllegalAccessException e ) {
RuntimeException re = new RuntimeException( e );
throw re;
return null;
}Need to think about how to handle parameters and return values.
Btw. Do i need to implement the EventHandler methods synchronized?
