Accessing ADF model within Struts based portlet

Hi,
I cannot seem to access and initialise the model from within a Struts based portlet.
Has anyone been able to get this right, and if so, would you mind sharing it with me.
I suspect it has something to do with the attributes that are being stored in the oc4j session not being visible in the portal session.

Hi,
Not too worry, I sorted the problem out by adding code to access the servlet session in the struts renderer.

Hello,
Could you elaborate a bit? I am having trouble with deploying a Model 1 style JSP that uses ADF.
Thanks!!!

Struts and JSF Integration in OPDk-java based portlet

Hi,
thanks in advance for your help.
I'm developing a PDK java based portlet. For some reasons I cannot use the JSF bridge but I would like to integrate Struts and Jsf in my portlet, using Struts to manage actions and navigation and JSF (with ADF Faces components) for the view. I'm using the Strus-Faces library.
When I try to submit my portlet form, I receive the error "request URL not found on this server". I'm posting some exstracts of my code.
It's made of three pages: the main one "Integration1ShowPage", "error" and "result". The MainAction.java displays my mainPage, where there's a form. To keep it easy, when the user submits this form, the ActionName returns "success" and the "result" page should be displayed.
The MainAction works properly: the portlet is displayed but when I tried to submit the form I receive
The requested URL /provaDeploy/htdocs/integration1/integration1ShowPage.do was not found on this server.Could you please suggest me something?
Many many thanks,
B.

Hi,
have a look at this whitepaper for how to use JavaScript in ADF.
http://www.oracle.com/technetwork/developer-tools/jdev/1-2011-javascript-302460.pdf
This link here (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html --> see sample 71) shows an integration sample between a Java Applet and ADF. Its a similar use case to yours

Hi,
Thanks for the quick reply.
- is your portlet container running? -- YES
- do you run your consuming application from JDev? If so, is the proxy setting turned off, or having your localhost and IP as an exception? -- Im consuming it from jdev only and proxy is turned off.
- if running as a deployed application, is there a firewall between consumer and provider? - It is delployed in my machine only.
My application is Event Based Calendar, i have 2 dropdowns to select the month, & year also a button. when i click on the button i'm getting the following response in the browser
"Unable to process portlet action for portlet binding Event4_1"

In my managed bean if I do like this. Its works fine
public getItems()
DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcIteratorBindings =
bindings.findIteratorBinding("orderParentWBSListIterator");
// Get all the rows of a iterator
Row[] rows = dcIteratorBindings.getAllRowsInRange();
for (Row row : rows) {

Hi Frank
Thanks for the help, this Iterator is coming from the BPM, so rows and attributes should be there, I am able to fetch the rows and attribute in my bean as I updated.
Now if the things updated is wrong then how can I iterate through the all rows in my jspx page, using a foreach.
Thanks

Error while deploying the ADF task flow project based on a SOA human task

Hi,
I created a SOA project with a BPEL process containing Human task, deployed it and could able to test it successfully. I created ADF task flow project based on the Human task created in the earlier project and tried to deploy it. It is giving the following error. The idea is to display the task details in BPM worklist.

Apart from these, I have Model and View Controller projects in the application. If I create the ADF task flow based on a Human task in another sample application, it works fine. Only in this application, it does not work. Not sure what this error is. Any ideas?
Thanks,
Manoj

What I suggest is go into EM and undeploy this composite and all versions. (Only if you don't want the existing ones). Then redeploy your process. This will avoid the version conflict and create a new version. 1.0. Then the next time you try and deploy you need to either specify a new version or check the box to say the version can be over written.
cheers

Access JSF Pages within WEB-INF directory

Hi,
I am generating a project using JHeadstart 10.1.3
with the default setting for the UI Pages directory (/WEB-INF/page).
This means that the generated pages are placed in the page directory
within the WEB-INF directory.
The generated pages use ADF Faces and the problem is that I can't
get access to the pages in the WEB-INF directory
When I try to deploy to OC4J standalone, the pages in the WEB-INF directory
are not accessible.
I read that I have to construct a index.jspx file that forwards to
the first page (Home.jspx)
This is my index.jspx:
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0">
<jsp:scriptlet> request.getRequestDispatcher("WEB-INF/page/Home.jspx").forward(request,response);
</jsp:scriptlet>
</jsp:root>
This works, but I now have the problem of not getting a valid FacesContext:
500 Internal Server Error
javax.servlet.jsp.JspException: Cannot find FacesContext
at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:405)

at oracle.jsp.runtimev2.JspPageTable.service(JspPageTable.java:370)

etc. etc.
What is the required way of setting up the forward (and having a valid FacesContext)?
I know that this is a JHeadstart problem, but maybe you guys know how to solve it.

I do something similar in my index.jspx file - but I needed to add "faces" to the url path. This will have the faces servlet process it and setup the faces context.
Have you tried changing
request.getRequestDispatcher("WEB-INF/page/Home.jspx").forward(request,response);to
request.getRequestDispatcher("faces/WEB-INF/page/Home.jspx").forward(request,response);

Hi timo,
Thanks for ur reply...
we are using unbounded taskflow.
In Controller class(page def file), we refered the class that implements PagePhaseListener
The following override methods has created
public void afterPhase(PagePhaseEvent pagePhaseEvent) {
//In this area we used to read the session object file which is written and sent by another application(application to application navigate).
If session object file exists,will allow the user to navigate into the requested page else will navigate in to login(security aspect).
public void beforePhase(PagePhaseEvent pagePhaseEvent) {
Is we used Controller class wrongly ???
Is there any relationship with region controller???

Let me know if anyone got any clues?

User,
Apparently, you are an Oracle developer working on Fusion Apps. It seems to me it would be more appropriate to ask in an internal forum, seeing as that most of us here have no access to the software you're using.

403 error accessing ADF app / 500 Internal Server Error accessing page

Jdeveloper 10.1.3.2
AppServer 10.1.3
I have developed and ADF-BC application. It runs great using the local embedded oc4j server. I setup a deployment profile and used the ear file to deploy to the application server. It deploys without error. When I try and test it by drilling down to the app in the enterprise manager, I get a 403 forbidden error. If I try and access the main jspx page directly (http:/server:port/myapp/faces/app/myapp.jspx), I get a 500 Internal Server Error with the following text:
java.lang.NoSuchMethodError: oracle.adf.share.perf.StateTracker.isActive()Z

I have updated the ADF library on the application server per this document.
http://www.oracle.com/technology/products/jdev/howtos/10g/adf_runtime_update_howto.html
I used the manual method since jdeveloper is not installed on the AS. If it were I would use the ADF installer. Unfortuantely, it did not seem to help.

Oracle ADF Model and BC4J api reference in JDev 10.1.3.03

Hi
Where I can find Oracle ADF Model and Business Components API Reference in JDev 10.1.3.03? Maybe it's not ready yet?

I don't know how up-to-date they are, but the javadoc files are all archived into jar files in the JDeveloper installation at: <jdev-install-dir>\jdev\doc\ohj. Most of the business component interfaces and classes are covered in the bc4jjavadoc.jar. You can either open the index.html file of the jar in JDeveloper and move through the links in the preview pane, or use the jar utility (or other unzipping util) to extract the jar file into your directory structure and then access the html files directly.

OC4J hangs when accessing ADF DataPage

My application was working and all of a sudden, when I try to hit a DataPage accessing a table (Read Only on the JSP side) it hangs. If I try to hit any page after that using the same session is hangs up also. After debugging and stepping through a lot of code, the first hang is when it tries to call a sync on the application module in the oracle.adf.model.bc4j.DCJboDataControl class in the sync method. It blocks all further accesses in the the same session because of a synchronize in ADFBindingFilter.
My questions are:
1. Has anyone else seen this problem?
2. If so, what is causing it?
3. Have you fixed it?
4. How?

Hi,
seems that the proper subject is "NPE whn accessing EJB from ADF binding". The error message states that the tasklist_tasklistPageDef file cannot be instantiated as a binding container. Can you run other pages that use the same EJB ?

Help neded to run struts based applcation developed on Tomcat migrated

Hi,
My application is struts based running on Tomcat.
I want to migrate it on Weblogic 8.1. I am able to deploy it in the clustered environment(Weblogic 8.1)
I have also done the IIS integration to access the application.
Now problem arises when I access the URL, It shows Page can't be displayed error.
URL is
http://test.ABC.com/Context/logon.do
When I access the Machine name and port number (Seperate access to the machine)
Then it works fine.
I have three servers running on three diffrent machines.
One is admin and other two are managed servers.
Currently application is working fine on Tomcat.
Please let me know if you have any suggestions.
Thanks

mudebao,
Looks like you are using a java.util.HashMap somewhere in your model, and that hash map is being modified by more than one user/thread at the same time...
[url http://download.oracle.com/javase/1.4.2/docs/api/java/util/HashMap.html]Documentation for java.util.HashMap says:
Note that this implementation is not synchronized. If multiple threads access this map concurrently, and at least one of the threads modifies the map structurally, it must be synchronized externally.You need to use something other than a hash map.
