Customize af:query form based on ejb entity data control

Hi all,
on my application i have a simple table with an af:query form to search data.
One of the requirements is to have one of the search criteria be displayed and filled depending on certain conditions.
For example :
if the user has a certain role, the field should be read-writable but not filled so that the user can specify whatever he wants.
otherwise the value of the criteria should be something like the username but not be displayed (or at worse read only). Of course in the later case the user couldn't also add in when using the advanced query option.
How can i achieve this ? Do i have to write a custom QueryModel or could i retrieve the one via #{bindings.ImplicitViewCriteriaQuery.queryModel} and browse this object to remove/update the criteria ? Is there a clean declarative approach to this use-case rather than programmatic ?
I tried the second solution (not sure if it's the cleanest way) but at some point i end up with a ConcurrentModificationException when removing the criterion from the ConjuctionCriterion list.
any idea ?
btw i'm on jdev 11.1.1.5.0
thanks
-regards
Julien.

Well, the databound query created a sql where clause which is added to the base sql statement. If you don't have a VO where should the where clause been added to?
The view criteria are also more like a dynamic where clause and I don't think you can easily mimic the framework is you don't have a VO behind it.

Query forms based on detail block

My question is pretty simple: Is it possible to query a form (Forms [32 Bit] Version 6.0.8.11.3) based on a detail block? Let me explain my problem! I have a table called REQUISITION and of its field is STATUS_CODE. Then I have another table called STATUS that have the following fields: CODE, NAME, DESCRIPTION, PHASE, etc. The join condition between REQUISTION and STATUS is REQUISITION.STATUS_CODE = STATUS.CODE. On my form, all of the fields come from table REQUISITION but the problem is that we have over 30 different status and my user can't remember their names and phase. So I inserted two display fields on the forms and wrote a post-query trigger to populate the field with their corresponding names and phases. But now my end user are complaining that the fields don't allow queries to be performed which prevents them to use a query to know all requisitions that are on phase "Procurement" which corresponds to four different status_code. So I though in inserting the fields PHASE and DESCRIPTION into table REQUISITION and write a trigger that would populate those field every time the STATUS change but that would cause a problem when lets say STATUS 01 is part of PHASE "Procurement" then comes next week the company decides that is not longer part of phase "Procurement" but now it is part of PHASE "Purchasing" they would go the form based on table STATUS and change the field PHASE of the corresponding STATUS that they want. But now I have this data on another table holding information that is no longer valid. Sure I could write another trigger to change field REQUISITION.STATUS_PHASE whenever there is a change on STATUS.PHASE but wouldn't that be too much bookkeeping? Would be so much easier if I could query my forms based on the detail block (this case table STATUS and master block table REQUISITION)?
thanks so much in advance for any thought! Btw, I am open to other suggestions too!!!!!
gleisson henrique

if I understood you correctly, you can do this manually. what I mean is,
when the end user picks phase "Purchasing", you can change the where clause on the master block and execute the query to get the desired results
e.g.
v_cod varchar2(200) := 'STATUS_CODE in (select code from status where phase = ''Purchasing'')';
begin
set_block_property(requisition_blk,default_where,v_cod);
execute_query;ofcourse you have to change "Purchasing" in the previous code to the item that holds the user inputs
hope this is helpful

How to make a jsf parameter form with a selectOneChoice and data control

I want to make a parameter form with a selectOneChoice and store this value in a backing bean, so I can use as a bind variable in query. I already made it happen without data control
Can someone show how to do it in adf data control. With the wizard it tries put the value
in a viewobject but I don't have base or destination viewobject. I can change the pagedef
so it works to fill the selectOneChoice but then I want to store the selected value in a session beab
here is solution with the application module and request / session bean, I don't
think it is the right solution
thanks edwin

<af:selectOneChoice label="Desk" value="#{selectDesk.desk}"
id="DeskID"

The SRDemo has an example of a selectOneRadio bound to a parameter being used to pass to an ExecuteWithParams action (to automatically feed a view object's named bind variable. This is in the SRStaffSearch.jspx page.
Also, if you check out example # 72 from my blog:
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#72
There is another example of using a selectOneListbox to do the same type of thing.
The steps involved in creating something like this are to:
(1) Define your named bind variables on your view object
(2) Drop the "ExecuteWithParams" action in the operations folder of that view object from the Data Control Palette to your page as a "Parameter Form"
(3) Drop the specific attribute (nested child of the "ExecuteWithParams" action from step (2) as whatever kind of selectOneXXXX control you want
(4) Delete the extra field on the form you don't want.

Mobile app based on web service data control and VO with VC runtime error

Hi,
Jdev 11.1.2.3.0 + mobile extension.
Windows 7, 64 bit.
Reproduceable with Android emulator but not on iOS and iOS emulator.
I can not test on real Android device because we do not have it in our office.
So I don't know wether this issue is related to android emulator only or to android in general.
Also not reproduceable by Oracle support.
I have a VO "Employees" with a VC "department_id = :departmentIdVariable" and exposed the find method for this VO via service interface in AM.
(see demo video from https://blogs.oracle.com/shay/entry/developing_with_oracle_adf_mobile?utm_source=dlvr.it&utm_medium=facebook).
In a ADF mobile app I create a parameter form and amx:listView like demoed in the mentioned video.
Whenever I test this app on android emulator I get the error below.
Exact the same page used in a second feature works fine.
I found out that the problem only occures on the first attept (this means when I open the page on the second feature first then this will fail and the subsequent call of the first page will be successfull).
The problem does not occure when the web service data control does not contain a method based on VC with bind variable.

Does anyone has seen the above error ?
I have recreated the model and mobile app more than 20 times, re-installed Jdev, re-created Jdev settings (integrated WLS & Co), ran the web services on a different machine.
On my site this problem is 100% reproduceable with android emulator.

Hi, Peter, this could be an issue with proxy server setting. Are you behind a firewall when you test this?
iOS simulator would use Mac's proxy setting. Android Emulator has its own proxy setup - it's a bit complicated to get to and varies based on the Android emulator you are using. For 4.1 emulator (you should always use 4.x or above emulators), you would need to go into the emulator itself, and go to settings - Wireless & Networks - click More... - Mobile Networks - Access Point Names. You should see an Access point used by the emulator to simulate network connection. Mine says "T-Mobile US". You click on it, and then you can select the proxy attribute and set it according to your office's settings.
Hope that resolves the issue.
Thanks,
Joe Huang

ADF forms based on BPM human tasks - Invoking webservices/view objects.

Hi All,
Is anyone aware of whether the following is a valid implementation that has been carried out before.
1. ADF forms based on BPM 11G human tasks.
2.The ADF forms invoke webservices via Webservice data controls. It is pertinent to note that the webservice bring back complex data types. We've tried writing a few forms, resulting in data benig brought back, but not being able to print them to the screen.
3. The ADF forms also use View Object based on sql to bring back tables of data. If view objects are embedded within the forms, the applciation gives rise to a null pointer exception.
Considering the form will be invoked via a BPM worklist entry, is there a setting or configuration we should consider before hand. Is this feasible, is there knowledge of this being done commercially.
Any examples or information regarding the same will be immensely helpful.
Thanks and Regards,
Preethi.
NB : I have posted this in the BPM forum as well as I feel it is relevant to both BPM and ADF.

Hi Joonas.
Plese let me explain me better for your understanding
A big summary for what I meant it's the following:
1- In the procces you made, when you add the HT activity, you have to implement it, this means declare the input(s) parameters you want. This implementation create the .task file.
2- Create an application, and projects as HT you have. Each poject are based on the .task file, and automatically create a Data Control (for each project based on a .task) with all you need.
This w'll be an empty application, so you can customize it all you want. The task selected should have all the parameters previously defined. Those parameters can change if you want.
2- Create a page(s) in the task flow for the task implementation. You can even split the the payload of the task in differents pages, create your custom pages and any logic you need.
3- An important aspect is how to match these application with the HT implemented in the process. It's possible, it's a configuration en the Enterprise Manager.
4- Deploy your application
All these are explain in the book I mentioned
Th book you can find it here:

PS: Please, let me know if you need more details.

Form based authentication -- control URGENT PLS.

I am following Form based authentication. I have a login page. I have specified the security constraints in the web.xml.
I would like to know after the execution of login where will the controller go to?? will it go the controller servlet, followed by an action class??
For any typical event (such as create customer)---the following has been the flow:
controller servlet--> createAction-->createUserBD (business delegate) --> customerManagerEJB --> customerDAO;
Now in case of login..
After the execution of login (authentication is by form based authentication ) where will the controll go to?
My requirement is to store the logged in userID details in Stateful Session bean. how will the flow look like?

If the access is through a web invocation, control will go to whichever portion of the web app triggered
the security constraint. The ejb has no knowledge of the authentication. If you want to provide the
login details to the ejb you'll have to explicitly pass them from the web tier.

Query form in oravle forms builder 6i

i have two tables
the first one is master table it has many items (has twoitems primary key type number )
the second table has only three items (two items foreign key to the first block(master table )) and the last item is
is blob item
i build query form such as
first i build control block has two item (not database table )
then i build first master block
finally i build second table
i joined them with the two items
the picture not appeard when i execute query
how i can solve it

Does the query return records in your first block? In your second block?

EJB, JPA E MANAGED BEAN WITHOUT DATA CONTROL

How do I build a simple crud with no EJB without data controls. Exposing the methods of my bean class.
Who can help me thanks.
Edited by: 941064 on 15/06/2012 14:48

You'll write managed beans that access your EJB service facade.
You can use @EJB injection to get this working.

Add a form (based on query) to a form (based on table)

I have a normal form based on a table. I want to put in a little form in a region of this first form that is based on a query. They have one field in common.
How can I do this?
Elsie

Hi Elsie,
Effectively, you want to end up with a single form and save the data back into two or more tables?
If so, you could base the entire form on a SQL view and use an INSTEAD OF trigger to update the underlying tables.

Forms based on query? Is it possible in Oracle Portal?

here is my code that i want to use
SELECT a.first, a.last, b.Position_CD, c.skill_cd, d.team_name, d.team_country, d.club, e.structure_name
FROM Roster a, Roster_position b, roster_skill c, team d, team_structure e
where (a.Roster_ID = b.roster_id (+) and (b.roster_id = c.roster_id (+) ) and (a.team_cd = d.team_cd(+)) and (a.team_structure_cd = e.team_structure_cd (+)))
order by a.roster_id;
Is it possible for oracle portal to support such a query in a form?
Oracle portal supports single tables or views...master-detal...and forms based on procedures.
Since the above query associates with moro then one table..how might one create a form based on that query? Is their a way in oracle portal to create a form and have its record source be based on such a complex query and be able to update and insert data? I know and have tested that it works in Ms Access and i can update and add data in that above query. Hopefully oracle supports this. (*cross fingers*)
If i cant do what i said above...what advice or suggestions you guys have for me? If i use master-detail it won't work right because i need to involve all 5 tables.
Any help or comments are greatly appreciated!

When i made the above query a view and created an oracle portal form. I get this error when I try to retrieve all the records in that view i made above.
An unexpected error occurred: ORA-01445: cannot select ROWID from a join view without a key-preserved table (WWV-16016)
What does the "key-preserved table" mean?

How do I open up a form based on a query/parameter

Can someone please tell me how can I open the form based on a query and the query is based on a pre-set value. Thanks.
I am new to Oracle Form. Please treat me like a newbie. Thanks.

Hi,
If I understand u , you want to call a form
and execute query automatically with preset value.
Is that what you mean?.
1.suggestion: You can use the call_form, or open_form .
check all parameters like "auto query" and so on.
(see help-online for parameters to pass for call_form, open_form....)
2.Suggestion: In the pre-query trigger set the value.
in the When-new-form-instance
write this code:
Begin
execute_query; -- built-in procedure
end;
I hope this gives you an idea,
Regards

Performing form based authentication with entities

Hey everyone,
Im in a major dilemma.Im trying to perform form-based authentication using entities.I have created the entity class from the database,and I used a SLSB to access the bean method via JNDI(when I tried using dependency injection,there was an exception).I also cannot use hibernate as a persistent provider.I used toplink since it is the default in netbeans 5.5.1 and it did not raise any issues.But then,I noticed that toplink is most compatible with the oracle application server,and I use sun java system application server 9.1.I have not been able to successfully perform the authentication.
here's the code:note,there are still bugs as ive been going back and forth trying to find a solution and also because Ive been working with preexisting code.

please what do I do? or is there a better way? seems like my appserver(sun java system app server 9.1)doesnt support dependency injection as
there's always an exception in the server log when i try it.i use the default transaction provider toplink because use of any of the others raises an exception and my application index page never shows. please i need help? I want to be able to succesfully perform this authentication as its the only way i can move to the next level

Problem with 2 View Objects based on One Entity -Probably a Bug in ADF BC

Hi
I am using JDeveloper 10.1.3(SU5) and adf faces and ADF BC and to explain my problem I use HR schema.
First, I created 2 view objects based on countries table named as TestView1 and TestView2. I set TestView1 query where clause to region_id=1 and TestView2 query where clause to region_id!=1 in the view object editor and then I created 2 separated form on these 2 view objects by dragging and dropping from data control palette.
Now when I insert a record in the form based on TestView1 with region_id set to 1 and commit the record and go to the next form I can see the record in the second form which is completely wrong since it is against the where clause statement of the second form.
I am really confused and the situation is very wired and it seems to me something like bug in adf bc.Am I right.Is there any work around or solution for solving this problem.
Any help would be highly appreciated.
Best Regards,
Navid

Dear Frank,
Thank you very much for your quick response.
Reading your helpful comments now I have some questions:
1- I have commited the record in the database so shouldn't the query of view objects be re-queried?
2- We try to use ClearVOCaches (entity_name,false) in afterCommit of the base entity object but unfortunately it does not work correctly. after that,We got root app module and used findViewObject method to find all the view of that entity (we have found them by using name not automaticlly) and called executeQuery of all views. From my point of view it has 2 big disadvantages. First suppose that this entity is an important entity and 4 or 5 viow objects are based on it. Now, For inserting one record we should re-execute 4 or 5 view which I think makes some performance issues. Besides, If during the development one programmer add a new view object based on this entity and don't add the executeQuery in the afterCommit for this view, again we have the same problem. Isn't there at least a way that automatically refresh all related view objects however the performance issue still exists.
3- You mentioned that this issue is handled in the developer guide. Could you kindly give me a refrence which developer guide you mean and which section I should read to overcome this problem.(I have ADF Developer's Guide for Forms/4GL Developer's Guide , however I search for clearVOCaches and surprisingly nothing was found!!!)
4- Could you please give me some hints that from your point of view what is the best method to solve this problem with minimum performance effect.
Any comment would be of some great help.
Thanks in advance,
Navid

EJB entity beans and BC4J

I have looked at BC4J and it looks good. Buy my question is that isn't this frame work in direct conflict with EJB entity beans. I know lot of stuff that is there in BC4J should have been in EJB enitiy beans, but as a developer why should I go with BC4J and not the standard EJB stuff considering the fact that BC4J is properietery to Oracle?Any thoughts?

Vimal,
Without going into exhaustive detail here, I would like to recommend that you take a look at the BC4J Technical White Paper available from the JDeveloper page on OTN (in the 3.0 Technical Information section):
http://technet.oracle.com/products/jdev/info/techwp20/wp.html
Amoung other things to note, BC4J is based on pure Java, and is what we consider a 'white box', meaning, you as a developer have complete control over what is going on. You can extend any of the code generated to customize it.
Primarily though, the major benefit of BC4J is that we have taken care of most of the complicated communication code for you. Communication between the client and the data server, transaction handling, row locking, etc are already written for you. You just use, extend, customize what we have provided.
In addition, BC4J allows you flexibility in your deployment environment decision. Regardless of where and how you deploy your BC4J Application Module, the client is unchanged.
Those are the key advantages. Again, for more details, I would take a look at the white paper to see if it more fully addresses your questions.
