Sample Provider

I have installed JPDK 3.0.9.0.2. for Portal 3.0.9. I try to register the provider from sample.
I receive an error:
An error occurred when attempting to call the providers register function. (WWC-43134)
An unexpected error occurred: ORA-29541: class PORTAL30.oracle/webdb/provider/web/HttpProviderDispatcher could not be resolved (WWC-43000)
What to do?

I assume that you have gotten the test page successfully.
This class is a Java class in the Database, you may want to check you Portal Java classes to see if anything is invalid.

XPATH using XDK Samples provided by oracle.

Hi,
I have compiled the demo/cpp/new program samples of Oracle 10.2.0.3 and executing XvmXPathSample which makes use of 'processWithBinXPath' however I am getting correct results only for NODES ... and not text.
Example .
In pantry.xml -
"/pantry/shelf/supplies/*" - works fine and provides me with a list of all the nodes
however
"/pantry/shelf/supplies/paper_good[1]/text()" - does not provide me a string output ... it still detects a node output on the XPATHNodeObject.
Could someone help me out on this ?

JPDK - Unable to see Sample provider in repository - getting Error

I have been trying to intall the sample provider as outlined in
the document "Installing the PDK-Java Framework and Samples".
Everything works fine except that I am unable to see the
provider in the repository...even after I refresh the repository
or restart the server. I see the following error when I click
the Refresh Error link in the Portlet Repository;
wwpro_api_provider.get_portlet_list 09-OCT-2001
PROVIDER[1097547]: SampleWebProvider
LANGUAGE: us ERROR: HTTP_PROV_EXEC_EXCEPTION
I am able to see the test page fine and don't have a problem
registering the provider, it just doesn't show up in the
repository and I cannot add the provider to a page.
Has anyone encountered this problem?
Were you able to solve it?
Any ideas on how I might fix this problem?

Hi , me too I have the same problem.

Crystal report : can't add table in the samples provided by SAP

Hello,
I tried to add tables in the generic samples provided by SAP. I used the database expert and just added a new table but when I save the report in SAP and want to run it it is blank.
Is there another way to add a table ?
BR

Already tried all those tricks!
My question is concerning the standard layouts provided by SAP (downloaded from marketplace). The idea behind those reports is that you can use them as Templates.
The tables are not hardcoded with the table.field name but with a specific syntax that allows you to use those templates in any type of document (ex : you can use the template of sales order for delivery and invoices). The problem is that if you add a new table the report doesn't work!
Thank you for the response anyway.
Best Regards,
Arnaud

Problem Configuring the Web Cache Sample Provider

I am trying to install the web cache sample provider. The instructions indicate that the web cache user name and password need to be obfuscated.
When I execute the following command from Windows Command Prompt:
C:\oc4jext\jdk\bin>java -classpath c"\oc4jext\portal\jlib\pdkjava.jar oracle.webdb.provider.v2.cache.Obfuscate username:password
I get
java.lang.ClassNotfoundException: oracle.security.misc.Checksum
The installation instructions indicate that the command should work if the pdkjava.jar and the jawc.jar files are in the correct directories. Both are in the correct directories.
I've searched for the missing Checksum class but have not been able to find it in the version of oc4j that I am running. I am running a pre-configured version of oc4j, referred to as oc4j_extended. It is version 9.0.4.0.0 build 031125.1647.
Any help would be much appreciated.

Can you add the $JDEV_HOME/jlib/ojmisc.jar file to the classpath as well? This is the one that contains the Checksum class.

Works fine!
I ran loadjava again with the force option( -f) and everything went through successfully.

Error when register Url Service Sample provider

Hello, I followed the 'URL Services Installation Instructions' described in portalstudio in order to set up URL services in my portal environment.
I did succeed in invoking provider test page (http://<myserver>:<myport>/servlets/urlsample), but I'm not able to register the url service provider in Oracle Portal.

This is thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method.
I guess you are not using the proper version of JPDK for the URLServices that you are using.
Try looking at the URLServices installation/release notes for the version your are using for the JPDK version. Check this version against JPDK.

AdfActionEvent and AdfPage.PAGE.findComponent not working - Sample Provided

Ladies and Gents,
Using JDev 11.1.2.3.0.
I just can't get this simple example to work. On page load, I'm calling ADF's find component by id method, which for some reason, returns null. I can do the same thing by using javascript's getElementById and that finds the component just fine. However, if I use the getElementById and then push that into the AdfActionQueue, I get a different error 'Error: Object doesn't support property or method 'queueEvent''
Can anyone see off-hand what I'm doing wrong here?

Hi Frank,
I agree manipulating the DOM directly is generally bad (I've watched those training videos!), but after doing some decent searching (with quite a bit of trial and error) I'm not sure there exists a purely ADF way of achieving a solution.
Inside of a region, I have a master (Companies) and a child (Orders) table relationship. Within the same region, I also have a charting tool which displays the monthly order totals of the selected company. A customer can select a company and see the related monthly orders in the orders table along with a graph showing the visual sales. If I were using ADF DVTs, this would be pretty straightforward, but I am not. To get this to work then, I have a few obstacles.
1) On jsff load, the chart must initialize with the displayed monthly order data.
2) On new customer select, the chart must refresh with the newly displayed order data.
The easiest way to update the chart would be to hook into the orders table component and, whenever the shown data refreshes or initializes, also refresh the chart. However, I'm not sure where the hook is located for that so I'm back to my two obstacles.
For the first obstacle, ADF does not (to my knowledge) have an "on jsff load" option so I'm stuck with jquery's load and corresponding id lookup functions. In my case, that load function looks for a hidden output text component's value whose getter returns the order table row's current monthly data. This is somewhat of a hack that, in effect, calls a managed bean method from javascript. Now that I have that data, I can input that into my chart and refresh.
For the second obstacle, I simply hook into the customer table's selection listener and after the current row is updated, retrieve the order table's current monthly data, refresh chart, etc.
The question I asked is a simplified version of overcoming the two obstacles above and while my jquery $('#myRefreshButton')[0] is extremely brittle, it was only meant as a quick demonstration. One could make it less brittle by iterating through the returned array, making sure the desired element contained any regions / naming containers and had the myRefreshButton portion at the end of the id string.
What would be the desired ADF way of achieving this result? Do you do something with your Data Visualization Tools that might be applicable here? Is there a way to hook into the child table and refresh my chart any time child table refreshes or initializes?

Flex Mobile - Sound Effect not Playing on List snapping (code sample provided)

Hello All,
I'm trying to figure out how to play a Sound Effect on the trigger of the "changing" event on a List.
So basically I have:
<s:List id="theList" width="100%"
            itemRenderer="MyIconItemRenderer" verticalScrollPolicy="off"
            pageScrollingEnabled="true" scrollSnappingMode="center"
            caretChange="playSound(event)"> ... </List>
So the list above snaps to the item to be centered, though I would like on every snap, for it to make a click sound. I've added the method for playing the sound as:
private var tickChange:Sound;
private var soundEffectURLRequest:URLRequest = new URLRequest('/assets/sound/click.mp3');
protected function playSound(event:IndexChangeEvent):void {
     tickChange = new Sound(soundEffectURLRequest);
     tickChange.play();
The Sound effect plays, though it's not playing at every Snap interval, so if I scroll fast among them, it's not playing, only on the last selection.

I can´t believe it.. While writing the previous post, I thought on a really simple solution and compiled it to give it a try. It works perfectly!
As simple as setting the "cacheAsBitmap" property to "true" on the Spark lists of the views!!

Hi Sharmila
I appreciated your help but I cann't yet figure out the problem.
First of all the listener is up.
The datasources.xml file is like that:
     <data-source
          class="com.evermind.sql.DriverManagerDataSource"
          name="OracleDS"
          location="jdbc/emulatedPortletPrefs"

          ejb-location="jdbc/portletPrefs"
          connection-driver="oracle.jdbc.driver.OracleDriver"
          username="portlet_prefs"
          password="portlet_prefs"
          url="jdbc:oracle:thin:@localhost:tcp:1521:infraDB.localhost"
     />
where ifraDB.localhost is the Global database name
and the 1521 is the port of the listener
If you can point out any mistake please let me know!
Thanks alot for the help!
