How to use global session in ADF

Hi all,
My problem is that I have several sessions that connect to a table in an ADF application. If I update some data in one session and commit, the other sessions do not see it until they requery the data because they are using their own local sessions and caches. I want the changes to be seen by all the sessions. Is there something like a global session in ADF?
Thanks in advance,
S/\EE|)

Hi,
From the documentation
"For example, say you have a page that lists all products, and a user can navigate from that page to another page to create a product. A button on this page both creates the product and navigates back to the list page. In order for the user to see the product just created, you must set the iterator binding for the product list to cacheResults=false. Doing so forces the iterator to reexecute when returning to the page and display the newly created product."

How to use Multiple selection in ADF faces

i i would like to know how to use an multiple selection (ADF select many choice) to update the database.

Hi,
Timo is correct that there is no automated way for doing this. You can access the select many selection from a managed bean either accessing the ADF binding layer or by referencing a managed bean array property. So the use case is important. Use case would include the database attribute type to update

How to use a session, created in a jsp page, in a php page

Hello, forgive me for the newbie question.
Here is my problem:
I want to have a jsp page create a session, set some session variables and then redirect to a php page which will access those same session variables.
I have the redirection worked out, but I can't seem to find out how to use the jsp session in my php script.
Is this possible at all, and if so, how does it work?

Note that javascript runs on the client side, and JSP runs on the server. JSP and the session objects are NOT available to javascript in reaction to the user.
If this function is called only when the page is first created, not when the user interacts with the page, or if you want that value to be constant with respect to the javascript, then you can do this:
<%
String someValue = (String)session.getAttribute("theAttributeName");
%>
<script type="text/javascript">
     Calendar.setup({inputField:"f_date_dfFirstPmtDate",
                                          button:"f_trigger_dfFirstPmtDate",
                                         singleClick:true,
                                          ifFormat:<%=someVale%>});
</script>

How to use a session bean in another session bean (or an EJB in a session)

JDev 11.1.1.4, WLS 10.3.4, Windows 7 x64
I have a login controller with a session-scoped bean that manages logins.
I have another session-scoped bean that manages menu security.
both modules compile and work fine now I need to share the data from one to another.
I need to reference the login controller in the menu security bean. How do I reference (include) the login bean in the security bean?
I tried an EJB - what a farce - these are supposed to be universal and easy ( basis of the oop in Java).
the bean is defined:
@Stateless(name = "SecurityEJB", mappedName = "ZITASApplication-ZITASModel-SecurityEJB")
I have tried :
ic = new InitialContext();
session = (SecurityEJBLocal)ic.lookup("ZITASApplication-ZITASModel-SecurityEJB#model.security.logic.SecurityEJB");
session = (SecurityEJBLocal)ic.lookup("ZITASApplication-ZITASModel-SecurityEJB#model.security.logic.SecurityEJBLocal");
session = (SecurityEJBLocal)ic.lookup("java:ejb/model.security.logic.SecurityEJB");
session = (SecurityEJBLocal)ic.lookup("java:ejb/SecurityEJB");
session = (SecurityEJBLocal)ic.lookup("java:app/SecurityEJB");
session = (SecurityEJBLocal)ic.lookup("java:module/SecurityEJB");
All return null pointers and claim the name cannot be resolved.
As you can see - I have found various claims to how to do this.
One way says create a sevlet, generate a listener and use the sevlet. Basically one for every EJB - a lot of work to use the EJBs
I would assume that this would be one of the easiest parts of java - as it is the foundation of re-usability and oop.
I can do either in the application - the added complexity of the EJB is less desirable - but better programming?

Hi,
ic.lookup("ZITASApplication-ZITASModel-SecurityEJB#model.security.logic.SecurityEJB");This should work with remote interface. If you want to lookup local interface, you need to register it in web.xml. Quote:
To access the business local interface you need to define ejb local references for your component environment (i.e. from your servlet environment). You can do this by defining references in your web.xml. For example:
<ejb-local-ref>
<ejb-ref-name>ejb/BusinessLogicBean</ejb-ref-name>
<local>packagename.BusinessLogicBean</local>
</ejb-local-ref>
To lookup your local reference from your servlet you need to use the following JNDI reference:
java:comp/env/ejb/BusinessLogicBean Another one
First, declare a local ejb reference in your web.xml file (This will add it to JNDI):
<ejb-local-ref>
<ejb-ref-name>ejb/Foo</ejb-ref-name>
<local>simple.ejb.FooLocal</local>
</ejb-local-ref>
Then it can be looked up from JNDI:
InitialContext ctx = new InitialContext();
FooLocal foo = ctx.lookup("java:comp/env/ejb/Foo");Hope this helps.

Your help is greatly appreciated.

WHAT I WOULD LIKE TO DO IS TO MOVE o_ref TO o_ref2 and then display:

I now have the following code. But when I check for syntax I get different error. They are at the end of the list.
Here is the code the way it stands now:

Here are the errors I get:
The field "DREF" is unknown, but there is a field with the similar name "OREF" . . . .
When I replace itr by OREF I get:
"OREF" is not a data reference variable.
I then try to change it to dref_tab. I get:
"DREF_TAB" is not a data reference variable.
Any idea? By the way, must there be a HANDLE event for this to work?

User,
If you are using ADF Business Components, you can right-click each application module, select "configurations" and edit the configuration you are using. On the initial page of the configuration dialog, you can specify to use either a JDBC URL or a Datasource - you just need to choose Datasource and then provide the name by which to access it.

I'll not comment about the use of pessimistic locking like this in a web-based app.ok. am not use pessimistic locking.

How to use the session id provided by fuego.papi.ProcessServiceSession

Hi, I'm wondering how to reuse the session id provided by the ProcessServiceSession in the Oracle BPM 10g Process API (PAPI)...
After the processService.createSession(passport, "localhost") call, I get an ProcessServiceSession instance, wich has an getId() method, so... the question is:
Is there a way to reuse this sessionId in another call to the processServiceSession's methods?, something like: I have this sessionId "userName321321321321321", so I want to reuse it to avoid passing the username and password in another moment of the application...
Moment 1: The user does the log in step and obtains a sessionId, then, the user exits the application... (I'm not going to execute the close() of the ProcessServiceSession, so, I keep the session alive)
Moment 2: The user goes back to the application and does some other things, so, with the generated session id in moment 1, I'd like to retrieve that session (by the session id) and accept him as valid user, without ask him the password again and allow him to do PAPI stuff.
Is this doable?

hi
yes , you can get SQL_ID from v$session and also you can join it for v$SQL also it get another details ......

How to handle multiple session in ADF using jdevloper11g

Hello All
i want to use the form in Multiple sessions.
i have one sign up form. user enter only 4 to 5 fields & he may not fill the the manditory field & he left.but data base dont give the error to him. but next day he will come at the next day to complet his sign up i.e. when he commit the all detail that time all validation will hapen.
for that i use one table without constrain to store the temarory detail.& use other table (with constrains) for final submition.
1) i creat the view n entity for temparory table
2) & also i create views n entity for Final table
n i create one methos in viewRowImple file in that file i overrid create method from using this i set the value from tempary to final table...
but when user left the manditory field then it allow to submit the data in temparory field but when i copy that data to final table(with constrain) n user submit the data then validation happn i.e. "this fild is mandatory".when i click this error message it goes to first screen.
IS Thiis Possible.. in ADF

Generally this can be done.
I see a problem with your use case, which has nothing to do with jdev or java:
How do you identify the user when he comes back to finish the form?
For this you can't use information like session cookie or IP address because they change.
So you have to save some information about the user which lets you identify him when he comes back. All other requirements can be implemented by ADF.

How to use a session variable in Conditional Format?

Hi Gurus,
I created a session variable , called Actual_date,
using the following SELECT:
SELECT SYSDATE FROM DUAL
In a report title the following expression worked fine:
@{biServer.variables['NQ_SESSION.Actual_date']}
I red in a reply in this forum, under the
"Oracle BI EE Variables Overview"
that we can use the above format in Cond.Format.
However I got an error:
"The value entered msut date and Time..."
Any tips?
Thanks
Laszlo

It's because when you fired
SELECT SYSDATE FROM DUALYour variable have a LONGVARCHAR type (if I remember)
Check here how to find the data type.
http://gerardnico.com/wiki/dat/obiee/obi_server_variable_find_value
If you just need to get the current date, you can try the system presentation variable current time as :
@{system.currentTime} Good luck
