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:
ov 12, 2008 12:09:33 AM oracle.adf.share.security.authentication.JAASAuthenticationService doLogin

Can I somehow explicitly login a valid user or exclude the specific application module from authorization?

Hi,
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...

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.

Can you tell me how can we call function module in custom exit planning function.
Where should I embed the code

How to call Function Module from webdynpro application ,up on click url in

Hi Experts,
I need your help for the following scenario.
In my WebDynpro application , I am displaying the sales orders in a table.
one of the column in table i.e. sales order number is displayed with hyper link, up on click the sales order number column, i have to pass the po number to the a remotefunction with as one parameter and enjoy = 'x' as another parameter that should call me23n transaction and the transaction screen should be displayed in the webdynpro application with po details.
Thanks In Advance.
your help is rewarded.
Best Regards.
Rao.

Hi Rao,
 1.Create binding to view to Controller.
 2.Create table->Add column->Add table cell Editor(select LinkToAction UI Element in options).
 3. Bind the property text ->sales order number (Output/<model node>)
 4. Create an Event <salesOrder>
 // do null check
 // set your input parameters
 // input sales order number = current output sales order number
 // enjoy="x"
 // call controller's method() that executes RFC
 5. Bind this event LinkToAction property action-> <salesOrder>
To execute RFC, the code is available in sample tutorials.
Hope this helps

Siva

How to Call Function Module from XI Mapping

Hi All,
I would like to call a function module that resides in ECC through XI mapping.
Can any one please through some light on how to proceed ?
Regards

Hello Shabarish,
Thanks for the reply, Actually i would like to do date validation using ISHMED_CHECK_DATE_TIME FM inside Mapping.
I would like to do this way, please let me know how good is this
1) Expose the FM as a RFC enabled one
2) Use the following UDF code inside Mapping
3) do i need to import the RFC enabled FM into our XI??
4) Do i required to create any Communication channel for this?
function RFC_LOOKUP_API
Imports java.io.;com.sap.aii.mapping.lookup.;
String content = "";
MappingTrace importanttrace;
importanttrace = container.getTrace();
// filling the string with our RFC-XML (with values)
String m = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><ns0:Z_UDF_CREATE_ZTOR_REC xmlns:ns0=\"urn:sap-com:document:sap:rfc:functions\">";

m = m + "<I_UZEIT>" + MsgTime + "</I_UZEIT>";
m = m + "</ns0:Z_UDF_CREATE_ZTOR_REC>";
RfcAccessor accessor = null;
ByteArrayOutputStream out = null;
try
// 1. Determine a channel (Business system, Communication channel)
Channel channel = LookupService.getChannel("XI","GeneratedReceiverChannel_RFC");
// 2. Get a RFC accessor for a channel.
accessor = LookupService.getRfcAccessor(channel);
// 3. Create a xml input stream representing the function module request message.
InputStream inputStream = new ByteArrayInputStream(m.getBytes());
// 4. Create xml payload
XmlPayload payload = LookupService.getXmlPayload(inputStream);
// 5. Execute Record Create.
Payload result = accessor.call(payload);
InputStream in = result.getContent();
out = new ByteArrayOutputStream(1024);
byte[] buffer = new byte[1024];
for (int read = in.read(buffer); read > 0; read = in.read(buffer)) {
out.write(buffer, 0, read);
content = out.toString();
catch(LookupException e)
importanttrace.addWarning("Error while writing " + e.getMessage() );

finally
if (out!=null) {

How to call application forms from network directory on other machine

I have installed Oracle Application Server 10G Release2 without IDS (Developer) on my server. I put my application forms & reports on the same machine(APPSERVER) and run the application as follows:-
http://appserver.www.ebs.com:7778/forms/frmservlet?form=\\appserver\pass_3_1.fmx
My Application runs well. But i want to use the 'Pass_3_1.fmx' form from other machine's(SERVER) network folder as below:-
http://appserver.www.ebs.com:7778/forms/frmservlet?form=\\server\pass_3_1.fmx
I am not able to launch my application. It throws error 'Cannot read form \\server\pass_3_1.fmx'. I also tried mapping on F:\. But it didn't work.
Please advise . Thanks in Advance.
Regards

Hi,
I don't understand exactly your problem but I tel you that your application mast be reside in the application server and the URL to call your application shouldn't change:
http://appserver.www.ebs.com:7778/forms/frmservlet?form=\\appserver\pass_3_1.fmx
good luck.

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?

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 get application module instance from java bundle?

Hi!
I would like to build an application that would get all translations from a database table.
So I created application module for translations that contains a view object which is selecting translations for specific language from a database table. I exposed a method in application module as client interface which returns HashMap<String, String> for all translations for specific language. When I test my view and client interface method call they work fine.
Then I created java bundle classes to get translations for specific language. Then I tried to override public Object[][] getContents() method.
I tried to get my translations application module like this:
SharedTranslationsAppModuleImpl am = new SharedTranslationsAppModuleImpl();
Map<String, String> translationsMap = am.getTranslations(this.getLocaleCode); // Client interface method call
In getTranslations(String LocaleCode) I try to get that view (which would select translations from database) but it returns NULL and I get NPE error message.
So what is the right way to get application module from java bundle file? Now everytime application wants to get translations, application stops and displays NPE message.
Regards, Marko
I use JDeveloper 11.1.2.1.0

Marko,
you can't just instantiate an application module. An application module has to be set up, db connections and memory pools have to be initialized and ....
Can you describe why and when you try to read the resource bundle from the db and where the resource bundle is used?

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

META_REQUISITION_CREATE Create Requisition
META_REQUISITION_DELETE Delete/close purchase requisition
META_REQUISITION_GETDETAIL Display requisition details
META_REQUISITION_GETITEMS Display requisition items
META_REQUISITION_GETRELINFO Get Releasease Info for requisitions
For getting Purchase order data, use the function modules ->
META_PO_CREATE Create purchase order
META_PO_DELETE Delete reservation
META_PO_GETDETAIL Display purchase order details
META_PO_GETITEMS Display purchase order items
META_PO_GETRELINFO Display purchase order release information
Hope this will definitely help. Do let me know.
