You can use EJB 3 with WLS9.2 beta http://e-docs.bea.com/wls/docs92/ejb30/overview.html
With WLS8.1 you are stuck w/ EJB 2.x

Has anyone used JAAS with WebLogic?

Has anyone used JAAS with Weblogic? I was looking at their example, and I have a bunch of questions about it. Here goes:
Basically the problem is this: the plug-in LoginModule model of JAAS used in WebLogic (with EJB Servers) seems to allow clients to falsely authenticate.
Let me give you a little background on what brought me to this. You can find the WebLogic JAAS example (to which I refer below) in the pdf: http://e-docs.bea.com/wls/docs61/pdf/security.pdf . (I believe you want pages 64-74) WebLogic, I believe goes about this all wrong. They allow the client to use their own LoginModules, as well as CallBackHandlers. This is dangerous, as it allows them to get a reference (in the module) to the LoginContext's Subject and authenticate themselves (i.e. associate a Principal with the subject). As we know from JAAS, the way AccessController checks permissions is by looking at the Principal in the Subject and seeing if that Principal is granted the permission in the "policy" file (or by checking with the Policy class). What it does NOT do, is see if that Subject
has the right to hold that Principal. Rather, it assumes the Subject is authenticated.
So a user who is allowed to use their own Module (as WebLogic's example shows) could do something like:
//THEIR LOGIN MODULE (SOME CODE CUT-OUT FOR BREVITY)
public class BasicModule implements LoginModule
private NameCallback strName;
private PasswordCallback strPass;
private CallbackHandler myCB;
private Subject subj;
         //INITIALIZE THIS MODULE
           public void initialize(Subject subject, CallbackHandler callbackHandler, Map sharedState, Map options)
                  try
                       //SET SUBJECT
                         subj = subject; //NOTE: THIS GIVES YOU REFERENCE
TO LOGIN CONTEXT'S SUBJECT
                                                 // AND ALLOWS YOU TO PASS
IT BACK TO THE LOGIN CONTEXT
                       //SET CALLBACKHANDLERS
                         strName = new NameCallback("Your Name: ");
                         strPass = new PasswordCallback("Password:", false);
                         Callback[] cb = { strName, strPass };
                       //HANDLE THE CALLBACKS
                         callbackHandler.handle(cb);
                  } catch (Exception e) { System.out.println(e); }
     //LOG THE USER IN
       public boolean login() throws LoginException
          //TEST TO SEE IF SUBJECT HOLDS ANYTHING YET
          System.out.println( "PRIOR TO AUTHENTICATION, SUBJECT HOLDS: " +
subj.getPrincipals().size() + " Principals");
          //SUBJECT AUTHENTICATED - BECAUSE SUBJECT NOW HOLDS THE PRINCIPAL
           MyPrincipal m = new MyPrincipal("Admin");
           subj.getPrincipals().add(m);
           return true;
         public boolean commit() throws LoginException
               return true;
    }(Sorry for all that code)
I tested the above code, and it fully associates the Subject (and its principal) with the LoginContext. So my question is, where in the process (and code) can we put the LoginContext and Modules so that a client cannot
do this? With the above example, there is no Security. (a call to: myLoginContext.getSubject().doAs(...) will work)
I think the key here is to understand JAAS's plug-in security model to mean:
(Below are my words)
The point of JAAS is to allow an application to use different ways of authenticating without changing the application's code, but NOT to allow the user to authenticate however they want.
In WebLogic's example, they unfortunately seem to have used the latter understanding, i.e. "allow the user to authenticate however they want."
That, as I think I've shown, is not security. So how do we solve this? We need to put JAAS on the server side (with no direct JAAS client-side), and that includes the LoginModules as well as LoginContext. So for an EJB Server this means that the same internal permission
checking code can be used regardless of whether a client connects through
RMI/RMI-IIOP/JEREMIE (etc). It does NOT mean that the client gets to choose
how they authenticate (except by choosing YOUR set ways).
Before we even deal with a serialized subject, we need to see how JAAS can
even be used on the back-end of an RMI (RMI-IIOP/JEREMIE) application.
I think what needs to be done, is the client needs to have the stubs for our
LoginModule, LoginContext, CallBackHandler, CallBacks. Then they can put
their info into those, and everything is handled server-side. So they may
not even need to send a Subject across anyways (but they may want to as
well).
Please let me know if anyone sees this problem too, or if I am just completely
off track with this one. I think figuring out how to do JAAS as though
everything were local, and then putting RMI (or whatever) on top is the
first thing to tackle.

How to use ADF with weblogic Portal 10.3.2

Hello All,
I want to use ADF with Weblogic Portal 10.3.2. Can anyone guide me ?
Thanks,
*(' ')sman*

Hello,
To use ADF with WLP 10.3.2 you will need a WebCenter WSRP producer running the portlet, which you can then consume as a remote portlet in WLP. The documentation on how to do that is here:

Can i use multipool with multiserver

I have 2 different geographies(US and Europe). Corresponding to 2 different geographhies,
we have 2 different databases. Everytime if something happens to one cidb, bring
down the weblogic server, point it back to another CIDB and then start the server.
Now i know multipool can help me with. But the problem i have is , the document
says it can be used only with the single server, i have 2 servers. Can i still
use it. What are the pros and cons of using it? , is there any document on this,
meaning is there any document that tells what will happen if i use it in the multiserver
config.
thanks for your help in this
Nirmala

Hi
You can use it as long as you are using a DataSource to get connections and
your DataSource is pointing to the MultiPool.

I ordered my Macbook Air with Aperture two years ago. I now have an iMac - can I use that with Aperture in any way? I appreciate that it is a different computer but I am now the end user of both devices and I was just wondering if it was possible.
Thanks,
Sean

The answer would be in your software license agreement for Aperture. However if you cannot locate it you can ask in the Aperture forum, the link for that is:
https://discussions.apple.com/community/professional_applications/aperture
However I believe you can have Aperture installed on two machines however only one may be using it at a time.
On the new iMac launch the Mac App Store - Purchased - look for Aperture and download to your new machine.

I installed 5 but now I can't use it with Mac osx - how do I go back to my old version?!

I was prompted to install Firefox 5 on my Mac. Now when I try to open it says I can't use Firefox with osx. How do I go back to using the previous version - has it been written over? My previous version was fine!

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
Mozilla are working to prevent Mac users with non-compatible systems from getting the notification about Firefox 4, and also not displaying the "Download Firefox 4" button on http://www.mozilla.com

How can I use LCCS with ActionScript 3 and Flash CS4?

Hi,
Using Stratus I was able to create an an application using Action Script 3 and Flash CS4. The sample code on the Adobe site was quite straight forward and easy to understand. I now want to switch over to LCCS but can't find anything any where on how to use Action Script 3 and Flash CS4 with LCCS. Do I need to know Flex to be able to use LCCS? Everything was quite simple and easy to understand with Stratus and makes complete sense. But LCCS is really confusing. Is there any sample code on how to establish a connection in Action Script 3 and then stream from a webcam to a client. There is nothing in the LCCS SDK that covers Flash and Action Script 3. Please help! I found the link below on some forum but it takes me nowhere.

Hi,
Welcome to the LCCS world.
Please refer to the SDK's sampleApps folder. There would be an app called FlashUserList. The app demonstrates how LCCS can be used with Flash CS4. Its a pretty basic app, but should help you moving.
We are trying to improve our efforts to help developers in understanding our samples. Please do let us know if we can add something that would help others.
Thanks

How can i use ipad with apple tv

How can i use ipad with appletv

Assuming both devices are on the same network and that AirPlay is not turned off on the Apple TV, then simply tap on the screen when you are watching content you wish to stream to your Apple TV, then tap the airplay icon that appears in the control bar, choose the Apple TV from the menu that appears.
When displaying the content you wish to mirror on the iPad 2 (or better), iPad Mini, iPhone 4S (or better), double tap the home button (quickly) and swipe the bottom row of apps to the right to reveal the playback controls, tap the AirPlay icon and select your Apple TV from the list of available devices.

My iPhoto icon has a cross over it, when i open it, it You have "iPhoto" 9.2.1. you can't use this with this version of OSX? it used to work ?what's gone wrong?

my iPhoto icon has a cross over it, when i open it, it You have “iPhoto” 9.2.1. you can't use this with this version of OSX? it used to work ?what's gone wrong?

iPhoto 9.2.3 is incompatible with MacOS 10.9.3 Mavericks. If you are running Mavericks on your system you need to update iPhoto to 9.5.1. Only, the problem is, that this version is no longer available at the App Store.
The easiest way to get a compatible iPhoto version in that case would be to upgrade to Yosemite, MacOS X 10.10, and then download the most recent iPhoto version from the AppStore, iiPhoto 9.6, like LarryHN suggested.
If you cannot download iPhoto after upgrading to iPhoto 9.6 post back.
