ADF JSF, refresh collection using a DAO without a database - Best Practice?

I have previously developed a comprehensive application using ADF 10.12. This application did not use a database, instead I was manually populating collections of objects that data controls were generated for to talk to the ADF components.
This applciation was based upon the old (10.12) version of ADF and utilised the following structure;
DataPage (start.jsp) --> DataAction (getRecords) --> DataPage (display.jsp)
In this instance, by overriding methods on the getRecords DataAction I could populate the collection that was to be displayed on the display.jsp DataPage.
I am now designing a new application that will hopefully use the latest version of ADF (10.13). This application will also use collections of objects from an external source.
The structure of ADF 10.13 (faces-config.xml) is different to 10.12 (struts-config.xml) e.g.
JSFPage (start.jsp) --> getResults (navigation case) --> JSFPage (display.jsp)
Having read the ADF Developer Guide, and looked through example #60 (onPageLoad) that was developed by Steve Muench, I am aware that there are at least three options that I could use to get populate the collection of objects that are displayed on the display.jsp page when a button is pressed on the start.jsp page;
1. use a backing bean that extends PageController
2. use a backing bean that extends PagePhaseListener
3. use a backing bean that has a specific action that is assigned to the button
Q1a. which one is the most appropriate/efficient to use?
When the button is pressed on the start.jsp page, it will be set to call getResults navigation case on faces-config.xml.
Q1b. Is it possible to detect when this action is triggered, populate the collection of data which is bound the display.jsp JSFPage, and then allow the getResults navigation case to continue execution?
The application that I am developing will have the following structure;
recordObject - Object to hold a record
recordCollection - Collection of recordObjects
recordDao - DAO use to populate the recordCollection
When using 10.12 I did not have a separate recordDao (as it was query only) I had a refresh method within the recordCollection.
Q2. what is the most efficient way of achieving this? there will be one DAO per Collection and approx 30 Collections
Q3. does anyone have/can point me in the direction of any other examples where actions that trigger call navigation cases are overriden, custom actions are called and then the original ones allowed to continue?
Thanks in advance for your help/advice
David

Thanks for the pointers Steve, they have been very useful.
This is what I have done;
set up the following pages and navigation cases (show in bold) on faces-config.
start.jsp >> getSystems >> systems.jsp >> display >> display.jsp
systems.jsp >> new >> new.jsp
systems.jsp << back << new.jsp
added refreshCollection() as a button to start.jsp
set the button to call getSystems
added the collection as a read only table to systems.jsp
- this works correctly
added the collection as an input form to the new.jsp page
added the addNewRecord(systemObject so) function as a button to new.jsp
set the button to call back
- this is where I encounter a problem.
The addNewRecord(systemObject so) function takes a new record as a parameter and adds it to the collection. It is doing this but it is not populating the new record. I know that this is the case because when I return to the systems.jsp page there is a new record within the table but it is empty.
Q. How do I capture the values from the input form that is on the new.jsp page, set them to a new instance of an object and then pass this object to the addNewRecord(systemObject so) function?
Thanks
David

Is dao pattern is the best practice in projects

let me know if dao pattern is the best followed in all almost all the
projects though finding alternatives to it. please clarify this for me and also i do want to know the best practices of the industry in using design patterns.

There is no 'best' pattern. It is just all abouthow
and where to apply them. This is very true,but these are common
design patterns used in industry for standard
problems.
ost of the time patterns are used not for some
special reason but for more manageability and ease of
change.So if you have a small application than it's
ok but if you are working on big application which
are needed to be maintained over a time and changes
are frequent.Than its better to start learning about
patterns because their will be problems which right
now you can't see but eventually you have to take
care of.That is either incorrect or phrased poorly.
Patterns come about because someone analyzes different existing code bases and notes that there are similarities in the way they are built.
It isn't that they are easier to maintain but rather that because the pattern has similarities it is easier to comprehend, understand the limitations, understand the possible related patterns, etc. That might lead to easier maintainance but it isn't the reason. The reason is because, if and only if, the requirements/architecture lead to a situation where that pattern could be properly used.

When to use unattend.xml in task sequence - best practice?

Hi, I've tried researching this but not found an answer to my specific query.
We have ConfigMgr 2012 R2 with MDT 2013 although I don't think this is an MDT specific question.
I'm trying to create a Build and Capture task sequence for our Windows Server 2008 R2 and Server 2012 /2012R2 server builds utilising an UNATTEND.XML file to make some customisations that can be deployed for every build afterwards in a Deployment Task Sequence.
Specifically the addition of some Windows Features like SNMP and it's configuration and the addition of the Telnet Client. There are other bits like language settings and configuration items but I'm specifically interested in the Features part for my question.
In CM 2012R2 you now have the option under the "Apply Operating System" to use a captured image or an original installation source. However they work differently if you specify the use of the same unattended answer file.
The "image" deployment ignores all of the "add features" sections of the XML file and the "installation source" loses the configuration options from SNMP from the XML file. When you then deploy the captured image using
the same unattend.xml again the one from the "installer" now has all the SNMP features required and the one from the "image" is still missing everything.
So my question is as follows.
What is best practice for specifying an unattend.xml file in a task sequence. Is it in the build and capture TS or in the Deployment TS ?
or
Do I need multiple XML files, one for build and capture with some bits in and another for deployment with the rest in?
or
Should I be doing something else?
Although this is specifically asking about Server O/S we will be using the same methodology for Windows 7 deployment.

In this case DISM is only used to add the actual features... for configuration you could use a simple script that runs afterwards. Sample registry file:
SAMPLE REG FILE - HKLM-SNMP.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters]
"NameResolutionRetries"=dword:00000010
"EnableAuthenticationTraps"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters\PermittedManagers]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters\RFC1156Agent]
"sysServices"=dword:0000004f
"sysLocation"=""
"sysContact"=""
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters\TrapConfiguration]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters\TrapConfiguration\public]
"1"="127.0.0.1"
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters\ValidCommunities]
"public"=dword:00000004
Sample batch file:
SAMPLE SCRIPT FILE - ConfigureSNMPService.bat
@ECHO OFF
net stop "SNMP Service"
regedit /s HKLM-SNMP.reg
net start "SNMP Service"
Also some settings for SNMP can be controlled through group policy:

Using WebI with SAP BW Data - Best practice for introducing BW Accelerator

Hi,
We have a significant investment in using BOE XI 3.1 SP2 integrated to SAP BW 7.0 EHP 1 SPS05.
Now we intend to introduce BW Accelerator to improve the data fetch performance for the Adhoc (WebI) Analysis and the formatted reports built using WebI (Infoview).
Data handling in question is approx. 2 Million+ records for each WebI report / adhoc analysis (20 to 30 columns).
The solution could be BW Cubes --> BW Accelerator --> BW Queries --> BO Universe --> WebI using Infoview
Does it really help in introducing the BW Accelerator like the case described above ?
Understand that the BW Accelerator could improve the performance of the underlying data and hence the BW Queries do work faster; but does it really improve (9x to 10x) performance for the MDX Queries generated by the BO Universe ( BOE XI 3.1 SP2 ) & WebI.
What is the roadmap for the future wrt BW Accelerator and SAP BI BO Integration; if we intend to use WebI ?
Or should be migrate to BO Explorer as the front end for Adhoc Analysis ?
Is BO Explorer able to present 1 Million + records with 20-30 columns ?
What is the best practice / better on performance; as an integrated product / solution ?
1) BW Cubes --> BW Accelerator --> BW Queries --> SAP Integ Kit --> BO Universe --> WebI
2) BW Cubes --> BW Accelerator --> ??? --> BO Explorer --> ??? --> WebI ???
3) BW Cubes --> BW Accelerator --> ??? --> BO Pioneer --> ??? --> WebI ???
4) BW Cubes --> BW Accelerator --> ??? --> BO Explorer
5) BW Cubes --> BW Accelerator --> ??? --> BO Pioneer
6) BW Cubes --> BW Accelerator --> BW Queries --> SAP Integ Kit --> Crystal Reports (to handle above data volume)
7) BW Multiproviders --> BW Accelerator --> BW Queries --> SAP Web Analyzer (to handle above data volume)

Hi,
We have a mix of Adhoc Analysis (60 %) and Formatted Reports (40%). We selected WebI as the tool for the purpose & used it for requirements which process approx. 2M records. We faced bottleneck issues on performance (we are on BO XI 3.1 SP2 & SAP BW 7.0 EHP1, SP05).
We are further analyzing possibility to introduce BWA; if this can handle similar record processing & still preserve our investment on OLAP Universes, WebI, SAP Integration Kit & training users on WebI frontend.
I see a lot of documentation suggesting "BO Explorer and BWA" - understand that BWA would improve the DB time and BO Explorer would help on the Front-end / OLAP time.
Request your guidance on the road map & continuation of investment using BWA + WebI.

Using Accessor Method from Within Considered Best Practice?

I was wondering what is considered best practice in the AS3 world regarding this topic.
In C++ and .NET world, as well as PHP I would consider using accessor methods, instead of directly accessing the class property, bad practice due to unnecessary overhead.
What are your thoughts in this?

Getters and setters and bindable vars can be public, protected or private. Which one you choose follows standard object-oriented practices.
is just like a macro that defines a particular get/set pair. I would only use it on vars. Using it on a getter simply wraps the getter in another get/set pair which is wasteful. The Flex Framework rarely uses . Instead, we typically define get/set pairs with metadata so we can control what event fires and when. It also saves SWF size because the compiler doesn't have to generate a long and ugly name to avoid name collisions.

ADF, JSF in Weblogic Portal 10.3.2

Hi,
We are designing new portal application on weblogic portal.
Per Oracle recommendations, use ADF, JSF instead of using legacy JPF, NetUI (BEA technologies).
If we use ADF, JSF; My questions are
(1) How do we add ADF taskflows, JSF in to weblogic portal desktop/pages? Do we create portlet out of JSF, and display on desktop/page? If this is the case, what about ADf task flows?
(2) How do we integrate weblogic user profiles and UUP (unified user profiles) with ADF and JSF?
(3) Can anybody shed some light which this better?
(a) weblogic portal with JPF (Java page flows), NetUI --Legacy approach
or (b) weblogic portal with ADF, JSF?
Thanks,
Murthy

Hi Murthy,
We did a detailed analysis.
(1) How do we add ADF taskflows, JSF in to weblogic portal desktop/pages? Do we create portlet out of JSF, and display on desktop/page? If this is the case, what about ADf task flows?
--> Taskflows can be deployed as WSRP2.0 portlets. Note 2 options are there JSF page as portlet or taskflow itself as portlets.
(2) How do we integrate weblogic user profiles and UUP (unified user profiles) with ADF and JSF?
--> ADF Security can use Weblogic Server realm as the security provider. Entitlements in WLP will have to be provided based on Weblogic Server roles. In case you are using external LDAP then both can be integrated withe external LDAP
(3) Can anybody shed some light which this better?
(a) weblogic portal with JPF (Java page flows), NetUI --Legacy approach
Pros:
-Easy Development
-Well tested integrated
Cons:
-Future support
-Enhancements may not be available
-Not really portable or standards based
(b) weblogic portal with ADF, JSF?
Pros:
-If your on Oracle stack then great
-Standards based
Cons:
-JSF Portlet bridge issues
-ADF Faces does not work on IE6!
Well what we are going for is JSR 286, Trinidad components (Supports IE6), JSF.
Difficult choice.

ADF Task Flow Binding - Refresh ifNeeded being invoked even WITHOUT any Parameter change

Using JDeveloper 11.1.1.6.0
Issue: Task Flow Binding property "refresh = ifNeeded" seems to be triggered even without the mutation of the input parameter.
As per definition, "ifNeeded: refresh the ADF Region if the value of a task flow binding parameter changes." (Reference: 17.5 Refreshing an ADF Region)
Now for the setup which reproduces the issue.
I'll focus at the fragment bounded task flow level and will skip the jspx side.
taskflow: main-flow.xml
contains a single fragment mainFgmt.jsff
has a managed bean defined SampleBean.java as pageFlow scope.
taskflow: sub-flow.xml
contains a single fragment subFgmt.jsff
has an inputParameter SampleBean.java (because it is an input parameter, by default it will be at pageFlow scope)
!important - has a nested taskflow (task flow call as defined in the component pallete) called inner-flow (see below)
the nested taskflow is the default activity
the nested taskflow has an outcome pointing to subFgmt where outcome = "return"
taskflow: inner-flow.xml
contains a single fragment called stop.jsff
has a return activity without outcome = "return"
stop.jsff has a navigation pointing to the outcome.
Finally mainFgmt.jsff has a task flow binding (pageDef)
with id = "sub-flow.xml"
refresh = "ifNeeded"
parameter SampleBean being submitted as sub-flow's input parameter. (id=sampleBean, value=#{pageFlowScope.mainSampleBean})
Assume that code compiles.
In this scenario where the only tricky condition is the inner nesting (defined by !important), when the inner nesting decides to invoke its outcome to visit sub-flow's fragment, mainFgmt is restarting its taskflow which makes sub-flow start over again.
Another way of saying it is, if sub-flow starts a nested activity and that nested activity exits out to utilize sub-flow's view. The high level definition which is mainFgmt's refresh ifNeeded is restarting sub-flow.
In the above example if you notice, the bean (SampleBean) is not really being utilized except that it is completing the purpose of refresh=ifNeeded. This scenario is only to simplify the setup - in practical use this bean will be mutated to be utilized as a refresh mechanism.
Now interestingly, if I change the pattern a bit then the issue will not happen:
Don't use the nested taskflow (inner-flow) as the default activity, let a fragment of sub-flow hold the initial view.
Navigate to the nested flow.
Exit nested flow.
Everything works.
Now in this scenario, it seems like the sub-flow needs to have a view established first for it to be properly be used.
So my questions are as follows:
Can I consider the behavior of the refresh=ifNeeded as a bug in this usecase?
Would it be better to utilize a different way of refreshing (maybe combination of refresh condition) to get around the issue?
Is the use of the task flow as defined logical or does it cross any boundary or best practice that might be causing this behavior?

Hi,
actually you lost me in your description due to complexity. I lived under assumption that sub-flow already is a region on a view in main flow, but then you sad that
"!important - has a nested taskflow (task flow call as defined in the component pallete) called inner-flow (see below)"
which then confused me as to I have no idea if inner flow now is the second level nesting or first level nesting (should be second level nesting). If sub-flow is a region then having "has an inputParameter SampleBean.java (because it is an input parameter, by default it will be at pageFlow scope)" is an unnecessary broad scope because the region wont live longer than view scope.
Anyway, it seems that a region refresh is triggered by the lifecycle involved, which can be by design or a bug. I suggest you file a Service Request with support and provide a test case as purely from the description, its hard to parse and understand what is going on.

Cannot connect with SQL Server driver using Top Link with ADF/JSF

I have a TopLink/ADF/JSF project that I'm starting using JDeveloper 10.1.3. The database is MS SQL Server.

I'm not sure on the error, but you may be able to pass the "selectMethod" and "cursor" as a JDBC property in your connection pool. Since this is a DataSource / JTA issue you may want to post it to the general OC4J forum.
Otherwise as a workaround you could instead use a non-JTA DataSouce, or use TopLink internal connection pooling, or try another JDBC driver.

Do some processing before loading jsf fragment created using adf task flow

Hi,
I am working on JDev11g.
I want to create SelectItems of SelectOneChoice dynamically before loading jsf fragment created using adf task flow
I tried by implementing RegionController class's method RefreshRegion in my backing bean of jsf page fragement to do some processing before loading region
But it seems to be not feasible approach because it is getting called every time any component on fragement gets partially submitted.
Is there any method which is called only first time when region is loaded ?
Or any other solution to achieve this.
Regards,
Devang

Hi,
don't think so. You would need a phase listener, but I don't see how you get it in. Wha about using a dynamic region and then use the method that is called from the dynamic region first time it is rendered?

How to use oracle Portal with JDeveloper 10.1.3 ADF JSF

Hi all
I use JDeveloper 10.1.3
I found out that the latest Portal 10.1.4 does not support JSF ADF
IF I WANT USE PORTAL ,WHAT SHALL I DO?
Thanks

OracleAS Portal 10.1.4 does not support JSF portlets.
JSF support in OracleAS Portal is in development.

ADF JSF 10.13 how do you reference a binding from a command button?

I have developed the following code as a model as I am trying to utilise ADF JSF without using a database.
I have a collection called School. This has the appropriate operations that populate the school with a number of Child. A Child simply has a firstname and a surname.
I have generated data controls for these collections and created two JSP pages and added a navigation link as follows:
index.jsp --> goToSchool (navigation) --> school.jsp
I have then added a command button to the index.jsp page. When the button is then pressed the school.jsp page is displayed. This works correctly.
I would like to override the action of the button though so that before the navigation is executed I can get a handle on the school collection and populate it so that it will be displayed on the school.jsp page.
I have previously done this in 10.12 when I had the following setup:
index.jsp --> getSchool (dataAction) --> school.jsp
by overriding the getSchool dataAction.
I have looked through the 10.13 ADF user guides and tried various different things but have not managed to successfully acheive my goal of populating the school collection when the button is pressed prior to navigating to the school.jsp page.
I would appreciate it if you could offer any advice, and if possible let me know the recommended best practices to acheive this.
Thanks in advance for your help

Check out the ADF Tutorial (TopLink edition) chapter 5 has a section called:
Adding a Drilldown Link
I think this is what you are looking for.

Call PeopleSoft via ADF/JSF

I am trying to call a PeopleSoft page directly such as "Create Requisition" directly from a link on an ADF/JSF page. I understand the issue about authentication, but would it be possible to just call the direct page itself aside from the the left hand toolbar or top toolbar with the "PeopleSoft" logo?

Thanks for this Shay, it was very useful.
I've managed to get the page to automatically refresh the collection when it is displayed.
My next step is to use an inputstream to populate the collection and then pass parameters between both pages and methods in the same way as I have done using dataPages and dataActions in 10.12.
Thanks once again

Error in Refresh Collection Snapshot request in R12

Hi,
On running Refresh Collection Snapshot (standalone request) in Oracle R12 with the settings as
Refresh Mode: FAST,

and the rest as the default options; it completes with the following error:

I referred the metalink Doc ID: 174144.1 that shows a similar error but it is reported in 11.5.5.
I am running into the same error in R12.
I have also checked the profile 'MSC: Source Setup Required' to be 'Yes'.
What are the other parameters or settings I must do to run this request successfully without errors?
Please help.
Thanks,
Rubellah Rajakumar

Hi Rubellah,
Is your setup 'centralized' or 'decentralized'? If you are using a decentralized setup, then you should ensure that you have applied Collections Cumulative Update 5 (CU5) patch to BOTH source and destination instances. The patch number is 7361861. Once the patch is applied, set the profile option MSC: Source Setup Required to Yes on the source instance and run a 'Complete Refresh' Data Collections. This should cause all of the objects on the source instance to be dropped and recreated. If this does not resolve the issue, the I would suggest logging an SR with Oracle Support.
Thanks,
Brett

JSF - Best Practice For Using Managed Bean

I want to discuss what is the best practice for managed bean usage, especially using session scope or request scope to build database driven pages
---- Session Bean ----
- In the book Core Java Server Faces, the author mentioned that most of the cases session bean should be used, unless the processing is passed on to other handler. Since JSF can store the state on client side, i think storing everything in session is not a big memory concern. (can some expert confirm this is true?) Session objects are easy to manage and states can be shared across the pages. It can make programming easy.
In the case of a page binded to a resultset, the bean usually helds a java.util.List object for the result, which is intialized in the constructor by query the database first. However, this approach has a problem: when user navigates to other page and comes back, the data is not refreshed. You can of course solve the problem by issuing query everytime in your getXXX method. But you need to be very careful that you don't bind this XXX property too many times. In the case of querying in getXXX, setXXX is also tricky as you don't have a member to set. You usually don't want to persist the resultset changes in the setXXX as the changes may not be final, in stead, you want to handle in the actionlistener (like a save(actionevent)).
I would glad to see your thought on this.
--- Request Bean ---
request bean is initialized everytime a reuqest is made. It sometimes drove me nuts because JSF seems not to be every consistent in updating model values. Suppose you have a page showing parent-children a list of records from database, and you also allow user to change directly on the children. if I hbind the parent to a bean called #{Parent} and you bind the children to ADF table (value="#{Parent.children}" var="rowValue". If I set Parent as a request scope, the setChildren method is never called when I submit the form. Not sure if this is just for ADF or it is JSF problem. But if you change the bean to session scope, everything works fine.
I believe JSF doesn't update the bindings for all component attributes. It only update the input component value binding. Some one please verify this is true.
In many cases, i found request bean is very hard to work with if there are lots of updates. (I have lots of trouble with update the binding value for rendered attributes).
However, request bean is working fine for read only pages and simple binded forms. It definitely frees up memory quicker than session bean.
----- any comments or opinions are welcome!!! ------

I think it should be either Option 2 or Option 3.
Option 2 would be necessary if the bean data depends on some request parameters.
(Example: Getting customer bean for a particular customer id)
Otherwise Option 3 seems the reasonable approach.
But, I am also pondering on this issue. The above are just my initial thoughts.
