Share http session across multiple EARs

I am curious to know the following:-
--> is it possible to share http session across multiple EARs running on same Weblogic application server.
i.e weblogic server/Jboss
--> is it possible to share http session across multiple EARs running on different Weblogic application server.
i.e weblogic server/Jboss
Please share the steps/way to acheive the same.

What are you trying to achieve / accomplish by splitting it up?
e.g. Clean Build in workshop will be faster for multiple EAR's , but unless you have all your application level libraries as shared libraries you might increase your runtime footprint. or you might want independent deploy/redeploy for your apps etc.
If however you need the session to be shared , that these aren't really independent web-applications and shouldn't be separate ear's. In most cases though you dont actually need the session as shared (e.g. a user's data is fetched from the database , you dont really need the session shared, you need a single shared sign on). So when you say is the session shared, what is the data that you need shared? should it be in the session in the first place?
And finally are these webapp's really independent (functionally ) or not?

How to share a session across multiple jws?

Hi!
I have this problem.
I'm looking for a way to have shared sessions, available across multiple JWS with WLW 8.1
I try to get a session with this code:
WebServiceContext wsContext = WebServiceContext.currentContext(); WebServiceSession session = (WebServiceSession)wsContext.getSession();
but it throws COntextNotFoundException....
I added the session descriptor in weblogic.xml to set the param CookiesEnabled to true, because I read that using this code works but requires that the client support cookies to keep the HttpSession object around.
But it's not works!
How can I get to HTTP session from a JWS?
And....it's possible to share a session accross multiple JWS?
Thanks a lot!

How to share a session across applications?

Hi
I am developing a web application. There will be two web applications (including mine) running in one servlet container. The user can navigate from one application to other and vice versa. We need to know how can we share a session across these applications. Any inputs in this regard will be helpful!

How do you share Aperture file across multiple users on same Mac?

How do you share Aperture file across multiple users on same Mac? Seems this should be a preferences choice.

When you share your library between users, you may run into permission and ownership problems, if both users are editing the Aperture library and not only reading it. To avoid that, it helps to put the Aperture library onto a separate disk or a separate partion of your hard drive. For s separate partition or disk you can enable the "ignore ownership on this volume" flag. Then all users can access the library as owners of this library.
You might try to put the aperture library into a shared folder on your mac, but that has caused problems recently, i.e. when the library also contains video files.

MAintain session across multiple DB Adapters.

Hi,
I am using a BPEL process which has multiple DB Adapters.
As far as I understand each DB Adapter call from BPEL is a different session.
Is there any way to maintain a same session across multiple DB Adapter calls i.e to make multiple DB calls in the same session?
thanks,
CD

Yes this is supported.
You'll have to take a look at the support for XA (distributed transactions).
See this thread for some good links to other info.

How to share dependant jars across rars & ears / avoid classcast exceptions

How can one share dependant jars between a ear application and a resource adapter and avoid getting a ClassCastException? 

In some appservers(such as Oracle) the resource adapter is the parent of your ear classloader, so a single instance multiple classloader problem doesn't occur. But in some appservers such as BEA Weblogic this isn't the case. Not sure why BEA decided to make resource adapter class loader seperate and not the parent of ear loader...

If I bundle the resource adapter specific classes in the corresponding module archive file, I will get a class cast exception, becos I will have a single instance and multiple class loader situation (assuming resource adapters uses its own classloader).

Second question related to the above: Web logic documentation recommends that we bundle the common files in APP-INF direcotory for embedded resource adapter apps. If I start bundling the resource adapter in an ear file, for every ear app we will have a rar bundled. What about the JNDI names? won't you have to rename the resource adapter differently for each ear so that there is no jndi name clash? Doesn't this defeat the purpose of having one common connector for all apps?

Here is a detailed description of what I want:
Let say you have a ear file. Let's say there is a common.jar shared between your ear application (say the ejb module uses it), and your resource adapter.

In the case of Oracle's OC4J I can see there won't be any problem of having this common.jar part of the resource adapter(RA). When the RA class loader loads the rar, it makes sure the common.jar files are accessible in the chain of all class loaders it is a parent of. So, the ear loader, ejb loader etc...will have visibility -> hence no class cast exception.

But what do clients do when they want to have their ear deployable across multiple appservers not just oc4j. BEA recently changed their class loader structure...their resource loader is no longer parent of the ear, so the ejb app in the ear doesn't have visibility into common.jar packaged with rar. So, the only solution was to bundle the common.jar file with the ear. But this causes problems, because we can have a situation where certain object instances (that are not serialized or copied) can be shared across class loaders. This ends up in the single instance multiple class loader situation->hence classcastexception.

The only solution I found was to make the common.jar file a shared library. That way only one copy of the class files are there for both the rar and the ear and its visibility is there not only for rar but for ear since it is loaded by the system class loader or shared library class loader (if ther eis one such).

Please convey best practise recommendation.

Sharing HTTP session on multiple logins

If two users login into an application with same credentials and from different browsers can i use same http session to handle both the clients.
My objective is how many ever users login with same credentials we use same session to handle them.
I do not want to stop multiple login with same credentials.

Associate the data with the logged in user instead of the session then.

Maintaining session across multiple browser windows and page refreshes

Hi there,
We're currently developing a Flex application with a couple of session-related requirements that we're not sure how to solve. Before we jump in and maybe go about things in the wrong way, I thought I'd post and see if anyone here knows of some elegant solutions!
Currently, when our Flex app starts the user is presented with a log-in screen which authenticates the user against our server. Client-server communication is done through BlazeDS.
Our first requirement is the ability to open a new browser window from Actionscript - this window will load a pdf document. The servlet that serves this pdf should deny the request if the user is not already logged in. The only way we can see to do this so far is to open the pdf url using navigateToUrl() with the '_blank' target, passing a jsessionid token as a url parameter. Is there a better way to preserve session state when opening a new window?
The second requirement is to preserve some application and session across browser refreshes. Our Flex app has several screens that the user can tab between. If the user hits F5 or the refresh button in their browser, we'd like the app to return to the same screen after the refresh. I've been looking into using BrowserManager to add a fragment such as #screen=2 to the url, but of course we only want the app to display screen 2 if the user has already authenticated with the server. Is there a way to reuse the user's existing session credentials after a page refresh?
Many thanks in advance for any advice anyone can offer on this. It could very well be that we're missing something about how BlazeDS uses / exposes session credentials that would make all of this easier to implement than we currently realise!

We use javascript to pass values between a 'data look up' window and the originating Servlet. If this is of any use, I can send you some examples.

Share firefox profile across multiple operating systems.

I've recently installed windows 8 on a VHD (my main OS is Windows 7) and I was wondering if it was possible to share the same firefox profile on both operating systems. I have the profile manager from [http://ftp://ftp.mozilla.org/pub/mozilla.org/utilities/profilemanager/ ftp://ftp.mozilla.org/pub/mozilla.org/utilities/profilemanager/], but when I tried to make a new profile at the location of my main profile, it instead made a subdirectory under my main profile. Is there anything I can do to share the profile between the two? I could always use sync, but I would like to share my addons, if possible.

* Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Sticky sessions across multiple content rules

Hi,
If a client PC initiates two requests which match different content rules on a CSS (first request http port 80 to CSS VIP downloads a small application. This application then sends a second request to the VIP, on tcp port 8085) can sticky rules be configured on the CSS content rules, so that they hit the same destination server, given that both content rules contain the same services, and hence be considered part of the same session?
Thanks

there is no sitcky accros content rules option on the CSS.
But there are solutions to this problem.
First, are you doing anything special with your HTTP content rule ? Like cookies or url inspection ?
If not, you can group the 2 content rules into a single one. You will have 1 Layer3 rule instead of 2 Layer 4 rules.
If you have L5-7 rules [http inspection], the previous solution is not possible.
You will need to maintain 2 rules.
You could then use a 'balance srcip' balancing method on both rules.
This algorithm is deterministic.
The same client will always go to the same server.
Hope this helps.
Regards,
Gilles.
Thanks for rating.

How to share projects/events across multiple users

what's the best way to share projects and events for multiple users on the same computer?
i want to be able to open fcpx in one user account and have access to all events and projects that i have access to as another user. basically, fcpx should look exactly the same in both accounts.

Welcome User in OTN,
to make two projects can access its classes you should goto the project property ---> Dependencies then add the other project.
in your case:
try to goto you Model project property ----> Dependencies ---> Edit Dependencies .
you will find your ViewController project. Expand it thin check to Build Output.
you can make this for ViewContoller project also as:
goto you ViewContoller project property ----> Dependencies ---> Edit Dependencies .
you will find your Model project. Expand it thin check to Build Output.

How to share one variable across multiple JVMs?

Hi,
How to share one string value across two applications, which are there in two different JVMs.
Requirement is, If I update one value(static) in first server through jsp, it should update second server static value too apart from first server.
I am using WebLogic 8.1, is there any MBean to access other application's static value?
Please suggest!
Thanks,

Can I share a video across multiple iPads so the sound is in sync or only playing on the native iPad?

I need to share video with approximately 10 ipad users during a meeting. Unfortunately, broadcasting or projecting in any fashion is not allowed. I'm hoping to sync the ipads or mirror the leader to the others.
Can anyone help??
Jen

Okay guys, since no one was able to help, i tried to figure it out, and i finally got it.There is this app on the app store called 'DropBox' which can be downloaded on both- your mac and iPhone/ iPad .Through this app, you can easily transfer files from imac to other apple devices and vice versa.
P.S. The files do get saved in the photo album.
Hope this helps

Maintaining session across multiple browsers

Hello All,
We have an application that runs using Apache Struts. One of the requirements is to pop-up a "data look up" window, i.e. a new browser window. The problem is, when I start this window any communication between this new window and server happens on a brand new session. I would like to maintain the same session as the parent window. Any ideas?

We use javascript to pass values between a 'data look up' window and the originating Servlet. If this is of any use, I can send you some examples.
