Import oracle.adf.view.rich.event.DropEvent; Not Found

Ok guys I have a problem. A large number of my imports are not found when I type them into my project. I am following a book and there is no mention of this happening so I have no idea what to do. I figure maybe it is about finding libraries and adding them to my view controller but I am not sure what libraries I should add.
These are the things that are missing
import oracle.adf.view.rich.datatransfer.DataFlavor;
import oracle.adf.view.rich.datatransfer.Transferable;
import oracle.adf.view.rich.dnd.DnDAction;
import oracle.adf.view.rich.event.DropEvent;
import oracle.adfinternal.view.faces.model.binding.FacesCtrlHierNodeBinding;
import org.apache.myfaces.trinidad.model.CollectionModel;
import org.apache.myfaces.trinidad.model.RowKeySet;
I am hoping that someone out there can help me with this problem

Here is a listing of all of the packages missing since this happened. Keep in mind Ive been using some of these packages with no problems for a while. Dunno what happened. Also I left out the corresponding errors that I'm pretty sure appeared because of this but if anyone needs a full error list I can post it no problem.

Oracle.adf.view.rich.context.ExceptionHandler is not working properly

Hi,
I am using Jdev 11.1.2.0.0 and weblogic server (10.3.5).
I have overridden oracle.adf.view.rich.context.ExceptionHandler class and registered under ADF Meta-INF/services folder. when I am deploying in the local machine it is working fine, but in production mode it is not catching the Faces(UI) level exceptions.
Please let me know any configuration have I missed in Production server or not?

+"So don't go for this solution to quickly and always think of alternative solutions. Sometimes a try-catch-final block does it better than sophisticated web exception handling. "+

Oracle.adf.view.rich.newWindowDetect.OPTIONS ADF_FACES-30163

Hi, all!
I have turned flag oracle.adf.view.rich.newWindowDetect.OPTIONS to ON in web.xml
+<context-param>+
+<param-name>oracle.adf.view.rich.newWindowDetect.OPTIONS</param-name>+
+<param-value>on</param-value>+
+</context-param>+
but when I look into the log (after starting server) :
+<Warning> <oracle.adfinternal.view.faces.webapp.rich.RegistrationFilter> <ADF_FACES-30163> <The application is running with the new window detect flag off. It is highly recommended that this flag be turned on to ensure proper functioning of your application when new browser windows are launched. In web.xml set the context parameter oracle.adf.view.rich.newWindowDetect.OPTIONS to 'on'.>>+
Why this situation is possible? Why weblogic doesn't see this param is web.xml?

in sample application the issue is not reproducible .Therefore ,try to delete the web.xml file and clean all the application and again create one more web.xml file and copy the contents of earlier web.xml.
Hope it will work as expected manner.

I am trying to import import oracle.adf.view.faces.context.AdfFacesContext and it says "Error(9,8): AdfFacesContext not found". Do I need to add any library to JDeveloper?

Hi,
To import this class you just need of ADF Faces Runtime library on your project.

Oracle/adf/view/rich/model/AsyncFetch Error in DVT

Experts,
We have some DVT components in our application which runs perfectly on integrated local Weblogic Sever. Once we deploy it to a Weblogic Standalone server, we are getttnig the following error while trying to access the DVT graph page. Rest of the application is working properly.
Error : oracle/adf/view/rich/model/AsyncFetch
followed by ADF Faces 60097
Jdev 11.1.1.5 and WLS 10.3.5
thnks

Solution : Go to EAR Deployment Profile Properties -> File Groups -> Application Libraries ->Filters and here you have to remove the libraries that are ADF DVT.

Edited by: Krithika on Dec 16, 2009 11:13 AM

Hi Krithika,
The class file mentioned here is part of adf-richclient-api-11.jar file which is a part of ADF Faces Runtime library. Could you please check if you have the mentioned jar file is in JDEV_HOME\oracle_common\modules\oracle.adf.view_11.1.1 directory? I suspect the jar file might be missing in your installation.
Assuming you are using JDev 11.1.1.2.0, you may also want to check if it reproduces in while running the application in the integrated WLS.

Oracle.adf.controller.faces.context.FacesPageLifecycleContext not found

Hi all,
I am using JDeveloper 11.1.1.0 and I am trying to do an application about security.
I have found some references on web and I have a bean that uses this line of code:
FacesPageLifecycleContext ctx = (FacesPageLifecycleContext)event.getLifecycleContext();
but on the line:
import oracle.adf.controller.faces.context.FacesPageLifecycleContext;
the debugger tells me: "class oracle.adf.controller.faces.context.FacesPageLifecycleContext not found"
What's the correct class to import?
Thanks

Hi,
not sure what you are doing - however I am not asking ;-)
Try import oracle.adf.controller.v2.context.LifecycleContext

I have got an exception pop up when recording through openscript. "Oracle.adf.view.rich.automation.ENABLED" is not enabled.

The popup message said to
Please check the web.xml file to enable it.
Otherwise ATS could not work properly.
I am wondering is it to changed at deployed production or test server?
So far I understand web.xml file belongs to a ear package.

I am just starting to learn OpenScript and ran into the same issue. For my simple tests I simply used a generic "Web" project instead of the "Fusion" one to proceed, obviously this is not a solution rather temporary workaround and I will need to configure the application with the appropriate parameter later on. Based on the documentation setting the property does have implications specifically for framebusting, so I am not sure this is advisable to do in production.
Web.xml is a deployment descriptor so I think you would need to add the context parameter to it manually or use deployment plan etc. to configure the application.

ADF progressIndicator without oracle.adf.view.faces.model.BoundedRangeMode

Hello
I am using progressIndicator for updating large number of database values. But it seems that oracle.adf.view.faces.model is not an opensource. But the progressIndicator using oracle.adf.view.faces.model.BoundedRangeModel. So any one please tell me is it possible to use progressIndicator without using oracle.adf.view.faces.model.BoundedRangeModel. I am updating nearly 10000 records. So it should use the progressIndicator.

Hi,
seems that your LOV implementation updates "MdlPrdId" on the table binding directly, which is not supposed to work

Hi Timo,
I have read this blog carefully, but still my problem is unresolved. I have to save file to location on Submit button in popup. I am not able to get example how to do so, that on Submit button I should move the file to file server.
My code is:
<af:inputFile label="File Name:" id="if1" showRequired="true"
autoSubmit="true"
value="#{backingBeanScope.spr2DownloadPageBean.file}"
valueChangeListener="#{backingBeanScope.spr2DownloadPageBean.uploadFile}"
binding="#{backingBeanScope.spr2DownloadPageBean.inputFile}"/>
Backing Bean:
public void uploadFile(ValueChangeEvent valueChangeEvent) {
// Add event code here...
System.out.println("fileUpdate invoked");
UploadedFile file =(UploadedFile)valueChangeEvent.getNewValue();
if(file!=null){
FacesContext context = FacesContext.getCurrentInstance();
FacesMessage message = new FacesMessage(
"Successfully uploaded file " + file.getFilename() +
" (" + file.getLength() + " bytes)");
I am not able to figure out code for Submit Button:
public String UploadButton_action() {
// Add event code here...
if(this.getInputFile().getValue()==null){
FacesContext context = FacesContext.getCurrentInstance();
return null;
Please suggest.

Oracle.adf.view.faces.model classes and serializable

Some (most?) classes in oracle.adf.view.faces.model - e.g., ChildPropertyTreeModel - are not serializable. If these objects are given the "session" scope, this causes problems. For instance, in a clustered environment with failover/load-balancing, session attributes must be serialized to be replicated to all cluster members. Adding one of these object to the session causes the serialization - and therefore the replication - process to fail. Does anybody know why these classes are not marked as serializable?

ADF Faces: oracle.adf.view.faces.CHANGE_PERSISTENCE

Does anyone have any information about oracle.adf.view.faces.CHANGE_PERSISTENCE. This appears to be un-documented.

This may help explain the situatin. I originally had JDeveloper 10.1.3.2 installed when I started this tutorial. I then installed JDeveloper 11 version 4 and tried to work the WebCenter Protlet tutorial. When I did it tried to migrage my settings. However, when I attempted to do the tutorial I noticed that it did not have the same options for the WebCenter new applications that would create a Portlet folder. So, I went back to 10.1.3.2 to work the tutorial. No error was flagged at this point but that is when the problems started occuring. I browsed my working directory (C:\Oracle\jdevinstance) where I had my applications stored (C:\Oracle\jdevinstance\mywork) and I noticed that I had what appared to be possible conflicting system files. I had the following system files listed under the working directory: system, system11.1.1.0.17.45.24, system11.1.1.0.22.47.96, and system11.1.1.0.22.49.49. I don't know if this is the issue or not and any feedback about these extra files would be apprecaited?
In addition, I create a new application (using 10.1.3.2) with a different applicaiton directory (C:\Oracle\jdevinstance\MyWork_10.1.3.2) and started the tutorial over. This time I had no issues with the JSP page and all of my web.xml files are the same version (2.4).
