Struts controller classes and ADF in JDeveloper 10.1.3 EA

I've noticed that ADF Struts has changed quite a bit from JDev 10.1.2. In the previous version of ADF Struts, the default data action class was oracle.adf.controller.struts.actions.DataForwardAction. In version 2 of ADF Struts, the default action class is oracle.adf.controller.v2.lifecycle.PageController. When overiding a lifecycle method in the DataForwardAction class, the method was always passed a DataActionContext object. The DataActionContext class had a method called getHttpServletRequest() so I could get a handle on the request object. On the other hand, the PageController lifecycle methods use the LifecycleContext object and I have yet to find a way to get access to the request object. Does anyone know of a way to get a handle on the Http request object? I've looked at the javadocs for the new Struts action classes but have found nothing that would help.
I also noticed that the DataForwardAction class (package = oracle.adf.controller.v2.struts.actions) has been changed in version 2 of ADF Struts and only a few methods remain. So I would assume that this class will no longer be used the same way it was in the past. Is this a safe assumption?

The task of customizing the PageLifecycle or handling events are now delegated to the PageController. These tasks were previously done in a subclass of the DataForwardAction. The DataForwardAction is now only responsible of bootstrapping the PageLifecycle.
</br></br>
In 10.1.2, reference to the model BindingContainer was done using a <set-property> for each DataAction. This is now done in the DataBindings.cpx file using a mapping between the path and the BindingContainer. This new mechanism is identical for Struts or Faces. Same with the PageController which is in 10.1.3 the common place to extend the behavior of the PageLifecycle or a ControlBinding for Struts and Faces.

URGENT controller class and XML file

Hi there,
I understand that oapagecontext.getParameter("FieldID") returns the field of XML. So for example in my xml i had this:
<oa:messageTextInput id="AActiveTo" dataType="DATE" viewName="RoleAdminVO" prompt="Active To" viewAttr="ActiveTo" readOnly="${oa.RoleAdminVO.SecuredFlag}" columns="15"/>
And on the front end I typed in "25-Aug-2006". My oapagecontext.getParameter("AActiveTo") should return "25-Aug-2005".
However is this only true if I put oapagecontext.getParameter within my processFormRequest of the controller class which the XML is pointing to?
Cheers

Or you can apply a XSLT transform as per http://blogs.msdn.com/b/mattm/archive/2007/12/15/xml-source-making-things-easier-with-xslt.aspx

thank you for quick reply. but I ran my application in the integrated weblogic server in the Jdeveloper.I did not deploy it to a standalone one.did you mean the default domain?

Struts and ADF in Portal

Hello. We have had a TAR going for some time regarding an issue with Struts and ADF in Portal. This is the summary of the TAR:
Customer followed the following document to create his Struts ADF application:
Developing an End-to-End Web Application Using the Default Technology Scope
at
http://www.oracle.com/technology/obe/obe9051jdev/ADFtoJSP/defaultendtoend.htm
After following the steps in the documentation, his application worked just fine.
- After this he decided to portletize his application using the following document:
OracleAS Portal Developer Kit (PDK)
How to create a Struts Portlet ?
at
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/ARTICLES/pdkstruts/portletize-your-app.html
When adding his portlet to a page, he basically received a portlet without any data, while the same worked fine outsi
de of Portal.
These are examples from the JSP file that do not show up in the portlet:
<c:out value="${bindings.DepartmentsView1.labels['DepartmentId']}">
<c:out value="${bindings.DepartmentId.label}"/>
</c:out>
We figured out that if we add the following filter mapping then it works fine:
<filter-mapping>
<filter-name>ADFBindingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
This filter mapping would mean that it maps all URLs to the ADFBindingFilter. I suppose this would not be necessary and we're concerned about the implications this might cause and we believe that there should be a better solution for this.
The final reply from support was that Portal is not yet supported with ADF technology. Does anyone have any comment on the above filter issue and other thoughts on using Struts and ADF in Portal? Another issue we found was that the PDK Struts tags do not support EL expressions. Have a look at this forum post:
Re: Struts and nested tags in parameters. Possible?

Adf bc jar for base entity classes and extending them existing project

Hi,
I am using jdev 11.1.1.0 and have created a base workspace/project and adf jar for my base entity classes.
1. I can consume this base adf bc jar in a separate new consuming workspace and create VO based on base bc classes or create new EOs that extend base bc entity classes.
2. Furthermore, for an existing consuming project that earlier included src/ of base entity (BC components), i can remove the dependency on bc source and bring in this new adf jar and everything including the view controller and the service/datacontrol works fine.
The issue i am running into is as follows.
- In the existing project (#2) above i try to create a couple of entities based on entities in my base jar; associations are automatically brought in. Note i am not overriding any attributes. My intent here is to generate .java and implement some code.
- I then try to make my existing VOs based on the newly extended entity (VO overview->Entity Objects-> Shuttle NewEntity from Available to Selected)
- I then try to remove the old EO from selected under VO overview->Entity Objects->Shuttle OldEntity from Selected back
- I get a warning dialog box that says something to the effect that some viewlinks are dependent on these old EOs in this consuming project.
- I tried to laboriously analyzed dependencies and it this dialog box does not make any sense as I have already extended EOs and the tooling should be able to let me use these
My questions
- Why I am not able to remove old entities from VO dependencies
- Is it ok to leave the old EOs in "Selected" along with the newly extended EO ? What are the implications for this?
- I also thought about extending base associations, but did not go anywhere.
In general, I am ok with consuming an ADF BC jar that has entities etc. but not clear about removing dependencies of base EOs on VOs when entities are extended and consumed in a pre-existing project that used base entities.
I can send a project if any PM is willing to take a look at it.
Thanks,
ps:
I have already gone over the following info
http://technology.amis.nl/blog/215/organization-of-bc4j-domain-eo-and-business-vo-package
.. wants to create an enterprise data model in BC4J, reflecting the Enterprise Data Model set up in the RDBMS. All (or at least most) business rules will be implemented in the Middle Tier – to take the load of the database and also allow developers not comfortable with PL/SQL to define and maintain the business rules. It is clear that this means that all applications that need to access – and manipulate – the database, need to go through the BC4J foundation layer. Martijn wants to define the Entity Objects – and their business rules – only once and share that definition between different projects. Each projects can create its own ViewObjects on top of these shared Enterprise Entity Objects.
http://radio-weblogs.com/0118231/2005/09/29.html
I am currently working on a project for a partner where we will be using ADF BC as our model layer for a large application. In order to keep the footprint of each application module down to a reasonable size, we are intending to create a number of separate 'root' application modules for each functional area of the application. Within, these 'root' application modules we will then use nested application modules to further partition the application. All of the application modules will be accessing the same datasource and will need access to the same database objects.
In order to separate our code between the development team and into function areas, our initial thoughts were that we would create an ADF BC model project containing Entity Objects for all of the database tables e.t.c. as these are common amongst all functional areas. We have configured all of the EOs for validation rules, defaulting values and extending doDML() as appropriate. Happy at this stage we then created a simple .jar file to deploy all of the definitions. Upon creating a new ADF BC project for each functional area we added the jar file as a library import into the new project. However when we the tried to create some new View Objects via the JDev Wizard we were unable to see the imported Entity Objects.
Is the only way to share Entity Object definitions between different ADF BC projects to manually copy the source definition files into the new projects src directory? Since this would mean multiple copies of the same components, it could prove to be a maintenance nightmare.Is there a way of doing it without creating multiple copies of the same object definitions?
The developer is spot on in their ideas of layering and reuse, and even has created a library for their reusable entities. This last step is not something everyone thinks to do. The missing step is known as "importing" components, so with that one extra bit of knowledge under his belt, he should be able to do exactly what he envisions. My little article called Difference Between Adding and Importing Business Components tries to explain the difference and gives the menu options to choose to perform the importing.

Hi,
since you followed the OC4J developer guide I think this question might be better handled there as well

How to retrieve content from DAO Class and process in Controller Class?

Hello
This is for the experts.
What is the best approach to passing a large set of data from Class A to Class B? I have a DAO Class that connects to a database to retrieve data. I tried saving the data in a collection (map) and passing the collection to Class B. The problem here is that the data is may be too large for a collection without increasing the heap size, it could cause out of memory exception. Instead I'd like to pass the data (row by row) on to the "Controller" Class where which will process each row. I am not sure how to do this without using a collection or some sort. Some tips will be much appreciated.
Note: MVC Rules dictates that Controller cannot call the DAO Class directly, it has to go through the Model which talks directly with the DAO Class.
Thanks

If the data is fetched based on some filter criteria, then just pass the filter criteria from class A to class B, and fetch the data from DB based on the filter criteria in class B.

HELP: include another page in with JDeveloper and ADF

Hi all,
I am trying to make a layout page with JDeveloper and ADF. But I just can't make things work. I have the pre-coded header and footer html pages and want to include them in a jspx somehow. I tried panelPage too, but the rendering style is away from our pre-coded header and footer.
1. Use jsp:include.
header works fine but footer is rendered before the page content, even if the footer is placed after the page content. Is there a way to customize the position?
<f:facet name="footerFacet">
<f:subview id="footerView"
binding="#{backing_welcomePage.footerView}">
<jsp:include page="/footer.jspf"/>
</f:subview>
</f:facet>
2. Use frameBorderLayout.
I followed the doc and use the document tag. But the frame page is rendered but none of included pages are rendered. So I got a blank page.

<f:view>
<afh:html>
<afh:head title="my frame page">
<meta http-equiv="Content-Type"
content="text/html; charset=windows-1252"/>
</afh:head>
<afh:body>
<afh:frameBorderLayout height="100%" width="100%">
<f:facet name="center">
<afh:frame source="topPage.jspx" name="topPage3"/>
</f:facet>
<f:facet name="top">
<afh:frame source="topPage.jspx" height="200" name="topPage2"/>
</f:facet>
<f:facet name="bottom">
<afh:frame source="topPage.jspx" height="200" name="topPage1"/>
</f:facet>
</afh:frameBorderLayout>
</afh:body>
</afh:html>
</f:view>

<f:view>
<af:document title="FrameBorderLayout Demo">
<af:form>
<af:panelGroup layout="vertical">
<f:facet name="separator">
<af:objectSeparator />
</f:facet>
<af:outputFormatted styleUsage="instruction" value="<b>A frameBorderLayout</b>"/>
</af:panelGroup>
</af:form>
</af:document>
</f:view>

for #1 have you tried throwing a verbatim tag around your includes like:
<f:verbatim>
<jsp:directive.include file="/includes/footer.jsp"/>
</f:verbatim>
it's how we got around intermixing html and jsf

COMMIT problem in TopLink, Struts, JSP and ADF Databinding sample

In the sample Developing a J2EE Application using TopLink, Struts, JSP and ADF Databinding,
I followed all the steps to build a department browse page and a edit page.
But when I get to Step number 23 in "Create a JSP to Edit Departments" I have a problem with the commit.
Only after I make a change in the form and click the sumbit button, the commit and rollback buttons become active. And After I click the commit button the data gets commited to the database but the page inofmation changes to the very first department record, not the current one.
How do I make those buttons active with out the extra click on the submit?
After I click the commit button, how do I keep the current data on the screen?
Thanks for you help.

Shay,
Thanks for the reply.
For #1, I was able to do the following and get away with not having to press submit first. I just removed the bindings for disable. I hope that does not cause any problems?
<input type="submit" name="event_Commit" value="Commit" />
<input type="submit" name="event_Rollback" value="Rollback" />
For #2, How I add an action on an HTML button? My UIModel.xml for the edit department page currently has two actions on it. Commit and RollBack. Is it linked through the "name" attribute of the input tag?

JDeveloper and ADF 11g Release 2(11.1.2.0.x) compatible WebCenter Version

We are looking to upgrade ADF to 11.1.2.0 and looking for WebCenter compatibility.
Could you please let me know WebCenter compatible version for JDeveloper and ADF 11g Release 2 (11.1.2.0.x) ?
Thanks
JP

Looking at 11.1.2.0.0 note on
http://www.oracle.com/technetwork/developer-tools/jdev/downloads/index.html
and seeing, "This version of JDeveloper doesn't include the SOA and WebCenter pieces - to use these components you'll need to download Oracle JDeveloper 11.1.1.5.0."
Does that mean, 11.1.2.0.0 can't be used with WebCenter?

Making a delete commit automatically with ADF BC, Struts and ADF UIX

I'm trying to create a delete action that commits to the database automatically using ADF Business Components, Struts and ADF UIX.
I have a browse page from which the user can view all records in the table, and perform edit, create and delete actions on the data.
When the user selects a record and clicks edit they are taken to a screen where they can amend the details of that record. Create works in a similar way, but the create action on the view object is invoked before taking the user to the edit page (this is done by linking the browse page to an ADF DataAction (bound to Create) on the Struts page flow diagram, and then linking the ADF DataAction to the edit page).
When the user clicks submit on the edit page, the container follows a forward from the edit page to an ADF DataAction bound to the Commit method, and then from there a forward back to the browse page.
This seems to work fine for edit and create, but when I try to do something similar for delete, it behaves unpredictably - sometimes the delete is committed to the database, sometimes not.
To be more specific, the way I have tried to implement the auto commit delete is as follows:
There is a UIX submitButton on the browse page called Delete. When clicked, this button triggers an event, which is caught by an event handler inside the page. The event handler causes the UIX servlet to take a forward to an ADF DataAction bound to the Delete method on the relevant view object. It thens follows a forward from the previously mentioned DataAction to another ADF DataAction bound to the Commit method for the application module. There is then a forward leading back to the browse page.
Has anyone else encountered similar problems?

did you figure this out?

JDeveloper, Toplink, and ADF advice.

We have application that was completely developed JDeveloper 10.1.3/4 with Toplink, JSF, ADF, and Session Facade; extremely similar to the SRDemo.
I am want to upgrade to JDeveloper 11g; however, the ADF Faces JSF will be migrated to Apache MyFaces Trinidad.
1. Why would this be better than migrating to ADF Faces 11g? Pros and cons?
2. Is Apache MyFaces Trinidad the future of Oracle's ADF?
3. What would be the best approach for upgrade to Toplink and ADF 11g?
Thank you.

1. Why would this be better than migrating to ADF Faces 11g? Pros and cons?It won't be better than using ADF Faces 11g - it is just more feasible for automatic conversion - we can't do automatic conversion from ADF FAces 10.1.3 to ADF Faces 11g since the UI capabilities are so drastically different. We migrate to Trinidad to allow you to combine Trinidad and ADF Faces 11g in the same application. (You can't use ADF Faces 10.1.3 and 11g in the same application).
2. Is Apache MyFaces Trinidad the future of Oracle's ADF?No. ADF Faces Rich Client is the present and future. Those are based on Trinidad.
3. What would be the best approach for upgrade to Toplink and ADF 11g?The basic thing to do is open the application in JDeveloper 11g - things should work after the migration.
Then you can start leveraging new capabilities such as the new ADF Faces 11g UI in new parts of the application.
You might want to ask on the TopLink forum if they have any specific migration tips.
