Askus (asktom) application for html db studio

Hello,
according to Tom Kyte you (the oracle html db team) wrote the basic "AskUs" Application which is used by asktom.oracle.com.
Have you ever thought of providing the ask tom application/functionality as a sample application on html db studio?
I would appreciate this as i'm searching for an easy to manage framework for publishing answers to questions, providing technical news information and rss-integration. This would be a good point to start.
BR,
Martin

Scott,
Thanks a lot for adding this demo app to your already tight schedule.
This app would help us a lot. I'm planning to develop similar kind of application for our organization.
Regards
Richard.

Mac - navigateToURL opens default application for .html files instead of browser

On Mac I have Adobe AIR version <string>3.1.0.4880</string> and I have selected TextMate for .html file as default application. With this configuration when I call navigateToURL in my app to open browser, it opens TextMate instead of default browser.
Following is the simple code to open URL:
var urlRequest:URLRequest = new URLRequest(url);
navigateToURL(urlRequest, "_blank");
Is this known issue? Any workaround for this?
Thanks,

Since you've remapped what your default response to .html files are, you can't use navigateToURL() or openWithDefaultApplication().
So it looks like you'll need to use the NativeProcess class:

Crash on search function for HTML Help file (.chm) when connected to a Visual C++ application

Crash on search function for HTML Help file (.chm) when
connected to a Visual C++ application
I use the RH_ShowHelp API command to connect a HTML Help file
(.chm file generated by RoboHelp Word X 5) to my Visual C++
application. My application is able to call up this HTML help file
in context-sensitive mode and everything is working great in the
Contents and Index panels EXCEPT when I click on List Topics (after
I enter a KEYWORD for search) in the Search panel.
I got an error that said “Unhandled exception in
xxxx.exe.(HHCTRL.OCX):0xC00000FD: Stack overflow”
I am able to execute this .chm file by itself and the search
function works well in this case. I am using HHActiveX.dll that is
created on 2/23/04. Is this the correct version?? Any advice what
to do here??

Hi agschin and welcome to the RH forums. The hhactivex.dll
file is not used by the search function so you can rule that our.
Have you tried recompiling and seeing if the problem still happens?
You can also start the Bug Hunter feature in RH - View > Output
View and then select the Bug Hunter button - and see if that throws
up any clues.

Themes on HTML DB Studio

This is really a question for the guys who look after the HTML DB Studio.
When are we likely to see any themes made available for download. I appreciate that it takes a long time to develop and test a theme and am very curios to see the work of people more graphically creative than myself.

Duncan

What is the difference between HTML DB and HTML DB Studio?

What is the difference between HTML DB and HTML DB Studio?

Doug,
Oracle HTML DB is a feature of the Oracle 10g Database which allows you to quickly & securely create web applications based on your data in Oracle.
Please see our homepage on OTN for more details: http://otn.oracle.com/htmldb
Oracle HTML DB Studio is a site where you can download HTML DB applications, utilities & tip and tricks for use with HTML DB.

Oracle HTML DB Studio Updated

All,
We've updated the HTML DB Studio with a new look, and also added a couple 1.6-specific applications.
http://htmldb.oracle.com/studio
You'll notice that all content is flagged by version - either 1.5.x or 1.6. Keep in mind that 1.5.x applications should import into 1.6 environments, but not the other way around.
We've also added a Search feature, which searches all content (applications, themes, utilities and tips & tricks) in the Studio.
Look for a few more 1.6 applications over the next couple of days from the HTML DB team.
Please feel free to post any feedback or comments here.
Thanks,
- Scott -

Scott,
Looks great!! I look forward to the upcoming sample applications from the HTML DB team.
It would be nice if the use of XML and Java is used in one of the upcoming samples.
Thanks.

Error in registering a provider for External Application for Web Clipping

Getting Error: The provider URL specified may be wrong or the provider is not running. (WWC-43176)
when trying to register a provider for an external application for Web Clipping

Hi Vineet,
The admins applied a patch to my version of the OracleAS 10g Version 9.0.4. and now I able to register a provider with the same URL but different Provider Name. I added My Yahoo Web Clipping from the Portlet Staging Area. That works fine but when I click on the check mail link in the Web Clipping Studio it gives me the following error. I have tried several times and I get the same error....
An exception has occured : WCS-514 -- Get status code 403 to URL http://us.rd.yahoo.com/my/prop/mail/*http://mail.yahoo.com/ by method get
Please click "Cancel" or "Back" in the above panel (if present) to retry. Otherwise, please try to click "Back" (from the browser) to go back to the Oracle Portal page to restart.

How to enable a partner application for Single Sign-On?

Can someone please advise me on how to enable my existing J2EE web application for the Oracle Single Sign-On?
My requirement is i want to provide the single sign-on authentication service to my J2EE web application. For this, I would like to make my application as a partner application similar like the OracleAS Portal.
I am using Oracle 10g ( OralceAS, Oracle Infra, OID ...)
I found the following service/APIs which Oracle provides. I am not sure which one is suitable for me.
1. mod_osso ( Static)
--- In this case, I have to make a entry in mod_osso.config file to protect the URL. should I have to register the URL again through single sign on admin page ("Administer Partner Application") after make a entry in config file?
2. mod_osso ( Dynamic directive)
-- in this case, I have to modify the code by providing the directives like 401, 499.. etc. So i don't prefer this as i don't want to touch my app.
--If I go with this option, should i have to register the URL with Single sign on server through SSO admin page ( as mentioned in the above step#1) ?
3. SSO SDK
- Since it was deprecated and need java coding, i am prefer this option.
-- however, if i go with this option, i will develop code by using SDK. in this case i need to register the URL in SSO server through admin page.. am i right?
Note:- OSSO server integrated with Active Directory for the authentication.

My question is that how I set user information in HTTP header? From my understanding, once I am able to set the user information in HTTP header, it is in base 64 format?Your application need to act like a proxy. You can invoke a HTTP request programmatically using java.net.URLConnection. You can set request headers using URLConnection#setRequestProperty(). Also see the API docs: [http://java.sun.com/javase/6/docs/api/java/net/URLConnection.html]. You only need to know the header field name where to set the Base64-encoded value in. You need to Base64-encode the value yourself.

Hi,
not quite sure the question is clear. The add cart command is a link defined in the JSPX file
<af:commandLink partialSubmit="true"
actionListener="#{shoppingCartBean.addItemToCart}"
id="cl3">
that points to
public void addItemToCart(ActionEvent evt) {
Map attributes = evt.getComponent().getAttributes();
invokeUpdateOp(new Integer(attributes.get( PRODUCT_ID_COL )+ ""));
in StoreFrontModule\StorefrontUI\src\oracle\fodemo\storefront\cart\view\managed\ShoppingCartBean.java . This is where you follow up then.
+"how i can make Repetition for the items in home.jspx"+
I can only assume you mean how to create the catalog items. Here I suggest you look at the demo source as this is what the demo is for. If you are new to ADF, I recommend that you first run a tutorial from here
If you are on 11g R1: http://www.oracle.com/technetwork/developer-tools/jdev/overview/index-100269.html
If you are on 11g R2: http://docs.oracle.com/cd/E18941_01/tutorials/toc.htm
No demo can replace proper learning, to be honest

Can you set a second "Open with:" application for a file?

Hi all,
I was wondering if something like this exists for OS X Lion or greater: you can set a default application to open a type of file, say Safari for all .html files, but can you set a second default application for a file?
I usually open files using command + o or command + down arrow from the Finder and I've often thought how good it would be to hit an alternate keyboard shortcut to open the selected file in a secondary default application.
For example, if I'm making a web page and have the .html selected in the finder I can hit command + o (or command + down arrow) to open it in Safari and if the file isn't open in my editor and is selected in the Finder I can hit, say command + option + o (or command + option + down arrow) to open the .html file in my editor.
Does anyone know if this can be achieved in OS X Lion or greater?
Any advice is greatly appreciated.
Thanks.

Hi all,
If anyone's interested in a partial solution, I've rigged up the following.
I ended up using an Automator action coupled with Spark to capture a keyboard key combination. Spark: http://www.shadowlab.org/Software/spark
I've used Spark before with good results, and although it's from 2008 it still works on Lion.
I created an Automator action that does two things:
gets the selected Finder items
opens finder items in the text editor I'm using.
I then saved the workflow as an application so that Spark could run it.
I've set up a keyboard shortcut that Spark picks up and calls my Automator workflow. It all seems to work nicely.
So, I've created a specific "open selected file with <text editor>" keyboard shortcut that should do for the time being.

WebDynpro proxy page with Webdynpro iView and SAP Gui for html iView

Hello,
I have a requirement to have a page that has at the top of it a webdynpro for java iView screen with several links that when pressed pop-up various data pulled from the back-end. This part is fine and presents no problem. Beneath this the requirement calls for a SAP Gui for HTML iView to be displayed. Which is no problem either. The problem occurs when one of the links in the java webdynpro application at the top of the screen is pressed it causes the SAP Gui for HTML portion to refresh and come back to the beginning. So for example you first navigate to this screen and you go into the sap gui for html portion and drill into 2 or 3 screens in the sap gui for html transaction. If you then press one of the webdynpro links the sap gui for html (which is a separate iView) refreshes and you are taken back to the initial screen. This only occurs when using a web dynpro proxy page. If I use a standard page the SAP Gi for html does not refresh. Unfortunately there are other things not mentioned here that require us to use the webdynpro proxy page.
Any help is greatly appreciated,
Bert

Use System admin -> System Config and find your system in the PCD (under portal content). Right click and open -> permissions. Find a user or group or role and give it the end user permission. I'd suggest the group Everyone.
