Using different app module configurtions

Hi,
How can i configure which application module configuration a jheadstart application should use? I've got a number of configuration (one for development, one for testing, one for production, one for unit testing, etc). I think that jheadstart is using the configuration specified in DataBindings.cpx.
I would like to be able to specify a configuration at install time in the enterprise manager. How do i do this?
Thanks,
Andrej

Andrej,
Which JHeadstart version do you use? If you are using 10.1.2, then JHeadstart does not do anything with the configurations, and leaves it all to ADF and ADF Business Components. You could post a question on the JDeveloper forum at http://otn.oracle.com/discussionforums/jdev.html.
Kind regards,
Peter Ebell

iOS 7 does not support multiple user accounts like you want.
If all the apps are different, you could set her up with her own page of apps, then just show her how to get to her apps page, or just buy her an iPad for herself.

Can different members of my team use different apps on different machines?

I purchased the Creative Cloud suite. Can different members of my team use different apps? I'm a video editor using Premier but my webmaster would want to use Dreamweaver, etc. He doesn't use my machine and I don't use his.

I'm not clear what you are trying to say. If you have CC for Teams, then ultimately it doesn't matter which programs the individual team members actually use as long as it's part of the subscription plan.

Use 2 App modules with connection to 2 databases on 1 UIX page?

Is it possible use 2 different Application modules with connection to different databases on one UIX page?
Thank you.

Yes.
Use a <bc4j:registryDef> with two <bc4j:rootAppModule>'s inside. Everything else is the same as the single root application module case.
More documentation is available in the UIX Developer's Guide available in the JDeveloper help system and online at:

How do I get my iPod touch to keep its place on music tracks when I use different apps?

Since upgrading to IOS6 (iPod touch 4th generation) my iPod returns to the start of tracks rather than storing where I was up to if I stop listening to a track and use other apps. It's really annoying when listening to audio books that it won't keep my place. How can I get it to keep my place again like it used to with IOS5

You need to use iTune to sync music not Windows Media Player

Slideshow editing using different apps

Love iDVD slide show edit capabilities, because it provides a picture number to 'slides' and a larger view of slides to allow easy movement of slides ordering with in a project. However, I dislike the known problem of 99 slide maximum, which creates a short audio drop out after being burned.
I understand that I can create the same slide show iMovie OR iPhoto, which I have tried. I do not like the limited view of slides and movement of slides within a project using iPhoto as an example, because it is much more time consuming.
Is there a way to export iDVD pictures (slides) edited in a desired order out of iDVD and into iPhoto where I can then added desired iTunes playlist of audio and then re-import this new Shared project back into iDVD (getting past the 99 slide limitation) as a movie or the like????

There are many ways to produce slide shows using iPhoto, iMovie or iDVD and some limit the number of photos you can use (iDVD has a 99 chapter (slide) limitation).
If what you want is what I want, namely to be able to use high resolution photos (even 300 dpi tiff files), to pan and zoom individual photos, use a variety of transitions, to add and edit music or commentary, place text exactly where you want it, and to end up with a DVD that looks good on both your Mac and a TV - in other words end up with and end result that does not look like an old fashioned slide show from a projector - you may be interested in how I do it. You don't have to do it my way, but the following may be food for thought!
Firstly you need proper software to assemble the photos, decide on the duration of each, the transitions you want to use, and how to pan and zoom individual photos where required, and add proper titles. For this I use Photo to Movie. You can read about what it can do on their website:
http://www.lqgraphics.com/software/phototomovie.php
(Other users here use the alternative FotoMagico: http://www.boinx.com/fotomagico/homevspro/ which you may prefer - I have no experience with it.)
Neither of these are freeware, but are worth the investment if you are going to do a lot of slide shows. Read about them in detail, then decide which one you feel is best suited to your needs.
Once you have timed and arranged and manipulated the photos to your liking in Photo to Movie, it exports the file to iMovie as a DV stream. You can add music in Photo to Movie, but I prefer doing this in iMovie where it is easier to edit. You can now further edit the slide show in iMovie just as you would a movie, including adding other video clips, then send it to iDVD 7, or Toast, for burning.
You will be pleasantly surprised at how professional the results can be!
To simply create a slide show in iDVD 7 onwards from images in iPhoto or stored in other places on your hard disk or a connected server, look here:

How do I share files on iCloud between different apps?

Hi,
how do I share files on iCloud between different apps?
I would like to edit simple plain text files on my Mac and my iPad using different apps. They don't see the content of each other. How do I fix this?
example:
when I create a .txt files:
Byword on Mac syncs nicely with Byword on iOS.
Ulysses 3 on Mac syncs nicely with Daedalus Touch.
BUT, cross-sync is not possible.... :/
How can I change this? - I would like to work with Byword on my Mac and Daedalus on the go.
Thanks in advance!

Cross-sync only works if an app on the iDevice allows it. For example, some apps (editors) sync with Dropbox (icloud usually isn't the thing to use) but only in their own folders.
If you save a file from the mac to it's own folder, A, on dropbox and on the device you use a different app that uses its own folder, B, then you won't be able to reach folder A on the device.
One thing to look for in editors that support Dropbox (most do, on a device - clearly all do on a mac) is whether they access dropbox using the root folder. From there you can drop down to any subfolder and reach the files you want.

Web Start - Can't Connect To App Modules

Has anyone had the problem of on being able to connect to their application modules deployed to Ora AS 10g when using web start? We can successfully use the tester on our local and deployed configurations for the app modules. We can also successfully run our JClient application locally and use our app modules deployed on the app server (and locally). We recently upgraded our containers from jdev 9.0.5.2 level to 10.1.2 level. Here is the stack trace I get:
JBO-30003: The application pool (net.nighthawk.talon.model.bc.portal.PortalModuleAS) failed to checkout an application module due to the following exception:

Hi,
Did you have a look at

If you are deploying your BC modules as EJB then this document also contains information of how to test this deployment within the BC tester.

How can I use the print module to print different size images on one large "canvas"?

How can I use the print module to print different size images on one large "canvas"? An example would be in Photoshop, go to file>new, and create the size paper I want, and move images of different sizes onto it.
I was thinking the print module would do this automatically for me.

You can't, at present. It's been a requested feature, so we'll see if it shows up in a future version, but it's not there at present.

I have 2 apple id's with different apps and data saved under each. It's very annoying so now I want to create a new id with my primary email address I use now. If I do that is there any way to transfer all my saved apps and app data like game saves etc so I don't lose all of that information and can easily switch to a singular apple id?

Apple does not transfer content bought with one Apple ID to another Apple ID. Apple will not merge two Apple IDs.
If most of your content was bought with the Yahoo! Apple ID but you now want the Gmail address for your Apple ID, the trick will be to change the address used for the Yahoo ID with the Gmail address. However, to do that you must first free the Gmail address from that other Apple ID. Use the instructions from Apple to substitute another address that is not used as an Apple ID for your Gmail address in the Apple ID with the Gmail address. Then, when the Gmail address is no longer used in an Apple ID, you can use the same instructions to substitute the Gmail address for the Yahoo address in the Apple ID with the Yahoo address.

I'm afraid if I set up iTunes accoutn for the tow of them, I'll have to re-purchase the music and apps (way too many!)

It can be done, but you will have to sign in to your account on her itunes to updated the apps. Try these instructions:

Need to Return immediately and commit the App Module on a different thread

I have an action that I want to return fast (immediately) but the server processing takes longer than acceptable. The results of the operation don't matter to the page submitting it and I want it to be able to navigate away even if the operation is not complete. I want to either be able to send a non-blocking server event from the browser or on the server side start a new thread that performs the operation allowing the original thread to return immediately. The new thread would need access to an Application Module in order to commit data. How would I go about accomplishing this?
Some thoughts
I've tried creating a ConcurrentLinkedQueue and putting the DataControl on the que, then in the other thread I pull it off the que, process and commit the data. This works unless the page is navigated away from. Then calling dc.getApplicationModule(); returns null.
I thought about using createRootApplicationModule in the new thread (since the new thread has no context) but don't know how that would work
This is the code in the run method of the new thread. In this example, I'm adding data to the app module in the original thread and committing the data in a new thread.
(like I said, it works most of the time.)
Object[] req = (Object[])que.poll();
DCDataControl dc = (DCDataControl)req[0];
try{
ApplicationModule am = dc.getApplicationModule();
if (am != null){
am.getTransaction().commit();
} else{
System.out.println("AM:null unable to commit ");
} catch (Exception e){
e.printStackTrace();
finally{
if (dc!= null){ dc.resetState();} // release app module
}

Thanks for the replies. I am aware of the inherent risks of running a separate thread within a managed container.
The use case is a performance logging operation. We have a internal web app used by a network of franchises with over 1000 users. We log response time and performances statistics to the database. When the user clicks to navigate or commit data, the response time that the user experiences is logged after the page has fully rendered either through a PPR or a full submit. This is done by submitting ADFCustomEvent from javascript on the page after rendering is complete.. The event sends up the time difference from when the user first clicked to when the page was fully rendered. This information is then merged with logged events stored on the users Session that shows the name and response time of every query that was executed during the previous request. Depending on the page this could be up to half dozen to a dozen or more queries. The logging operation as experienced by the browser is generally fast (<200ms) but sometimes can be as long as a second or more when the database gets busy. A half second is too long as makes the app appear sluggish if the user can't type or click immediately after the page has finished rendering. The logged data is aggregated so we know exactly how much of the page load was due to a slow browser/network, how much was database time, webservice call time, etc... If it's due to a slow database we can drill down and see which query is the culprit. These performance metrics are critical to operations and are charted throughout the day so we know exactly what our users are experiencing. All of our users use a custom firefox client that we control. Using this logging framework we were able to determine that upgrading to a Firefox 4.0 based client cut browser render time by more than half a second on average. We can also tell what type of hardware the user is running so can place the blame for poor performance where appropriate. We have determined that pages render considerably faster on Windows 7 than on Windows 98 with the same hardware. We are moving the logging tables off of our exadata database to a separate box to remove that load from the application database. Since we expect the other database not to perform as well we don't want it to affect the user experience, hence the need to log asynchronously. I would like to put the data on a queue and have a background daemon process read from the queue and commit to the database. I would like the daemon thread to be able to use BC components. I would prefer not to resort to using a web service because of the inherent overhead. The logging operation is not a long operation but is of high frequency so should be as streamlined as possible. The load is spread over 6 servers with 4 JVM's each (24 weblogic instances). I know it's possible to use BC components from a plain Servlet (which runs on it's own thread) so what I want is to have something like a servlet thread that loops forever processing my logging queue.
One other method I am investigating is using my own non-blocking ajax call that callls a servlet to perform the logging. I will need to pull out the timestamp contained within a client side ADF component along with the pages ctrl-state variable that is included with every ADF request as it uses this as the key to get to the data on the session. ADF really needs a non-blocking ADFCustomEvent for this type of request. (send and don't care about the response)
The client component with the server listener looks like this
<af:outputText value="#{pageFlowScope.perfClientTS}" visible="false"
id="perfClientTSField" clientComponent="true">
<af:serverListener type="logPerfData" method="#{perfLog.logPerfDataAction}"/>
</af:outputText>
The script that queues the ajax call after the page loads looks like this
AdfCustomEvent.queue(perfClientTSField, "logPerfData", {
typeId : typeId,
subTypeId : subTypeId,
responseTime1 : new String(responseTime1),
responseTime2 : new String(responseTime2),
openedVia: via
true);
I also tried calling the noResponseExpected() method on the event before queuing it but it still blocked the UI and caused an additional side effect in that the client sent two ajax requests instead of one. It somehow thought something on the client side needed to be synced with the server.
email me and I can send a doc with more details about how our performance logging framework works.
