What is the best way to Process non-JSF request??

I am engaged in new project using JSF.
We came across the serious problem that there is no-way
to let JSF execute action method of managed bean at the
first request.
That is because, JSF gets method binding information only
from pre-displayed UIComponent, it seems impossible to
let JSF know about the method binding info when they receive
the request from external system, or from non-JSF pages i n the
same system.
I get to two ways to solve this problem.
1. develop a custom-servlet
The tasks of the custom servlet is,
- receive a request from external system or non-JSF pages.
- get managed bean and execute it's action method.
- get next page info
- dispatch to next page through FacesServlet
2. use bridge-JSF page as a intermediation
This is kind of last resort.
As I described above, JSF can get method binding info, only
from components of pre-displayed pages.
So, I use bridge -JSF page to let it work as a intermediation.
It displays nothing, just click the commandbutton automatica
lly(by JavaScript).
Of-cource, I prefer 1 to 2.
Codes below are custom servlet sample , I made.
Pls let me know if it's ok or not.
thanks
public class FESFacesServlet extends HttpServlet{
    public void doPost(HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException {
/* init process */
        LifecycleFactory lFactory = (LifecycleFactory)
                                        FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
        Lifecycle lifecycle = lFactory
                                .getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
        FacesContextFactory fcFactory = (FacesContextFactory)
                                            FactoryFinder.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
        FacesContext facesContext = fcFactory.getFacesContext(getServletContext(), request, response,lifecycle);
        Application application = facesContext.getApplication();
/* set from-view-id */
        ViewHandler viewHandler = application.getViewHandler();
        String viewId = request.getParameter("fromviewid");
        UIViewRoot view = viewHandler.createView(facesContext, viewId);
        facesContext.setViewRoot(view);
/* find managed bean and execute it's action method */
        ManagedBeanBase managedBean = (ManagedBeanBase)application.getVariableResolver().
                                                resolveVariable(facesContext, request.getParameter("command"));
        String outCome = managedBean.start();
/* look for next page info */
        NavigationHandler navigationHandler = application.getNavigationHandler();
        navigationHandler.handleNavigation(facesContext, null, outCome);
/* dispatch to next page throw FacesServlet */
        facesContext.getExternalContext().dispatch("/faces" + facesContext.getViewRoot().getViewId());
        facesContext.release();
    public void doGet(HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException {
        this.doPost(request,response);
-

the common approach is kind of like your number 2)
but you dont need a commandButton
just have your first page redirect to your start page
e.g.
index.html
<html>
<head>
<!�redirect to startPage -->
<meta http-equiv="Refresh" content= "0; URL=index.faces"/>
<title>Start Web Application</title>
</head>
<body>
<p>Please wait for the web application to start.</p>
</body>
</html>

What is the best way to submit a Concurrent Request over a DB Link?

Hi,
We have a requirement to submit a Concurrent Request over a DB Link. What is the best way to do this?
What I've done so far is I've created a function in the EBS instance that executes FND_GLOBAl.APPS_INITIALIZE and submits the Concurrent Request. I then call this function remotely from our NON-EBS database. It seems to work fine but I found out from metalink article id 466800.1 that this is not recommended.

What is the best way to process / queue?

Hello,
I have a requirement:
1) Users create as many workflows as they like at any time.
2) During the execution each workflow changes it's status from e.g. 'Pending' to 'Active'.
3) Only one workflow can be in 'Active' status at any given time.
4) Processing of workflows occurs in FIFO mode.
We don't like the idea of having a trigger to watch out for the status of a workflow.
Can someone please suggest some more nice solution to making all workflows but one wait untill the 'slot' becomes available and then the workflow which is the next one in line becomes 'Active'. The queue comes in mind but I am not sure this will be the best approach.
Thank you.

I can't say whether JMS is "the answer" to your question, but if you're rewriting your application in Java, and need to send messages from one program to another with the ability to queue up messages somewhere if the receiving program is not ready to accept them yet, then using JMS sounds a reasonable approach. Note that both the sender and receiver of the message must use the JMS API (though some providers support other languages).
The JMS tutorial at [http://java.sun.com/products/jms/tutorial/1_3_1-fcs/doc/jms_tutorialTOC.html|http://java.sun.com/products/jms/tutorial/1_3_1-fcs/doc/jms_tutorialTOC.html] explains some of the key concepts.

What is the best way to process a dataset of 2000 records...

I have a problem where I get a collection of 2000 records. Using these rows I need to look for matches amongst existing rows in a table. Currently the procedure each row and scans the table for a match. Is there a way I can scan the table once for all possible matches.
Thanks

Assuming you can't retrieve the 2000 rows in one SQL statement another approach might be to create an object collection and cast this to a table in a subsequent SQL statement.
For example
CREATE TABLE test (abc NUMBER, def NUMBER, ghi NUMBER);
INSERT INTO test VALUES (1,2,3);
CREATE TYPE test_typ AS OBJECT (abc NUMBER, def NUMBER, ghi NUMBER);
CREATE TYPE test_coll_typ AS TABLE OF test_typ;
SET SERVEROUTPUT ON
DECLARE
coll test_coll_typ := test_coll_typ();
CURSOR cur_dupes IS
SELECT abc, def, ghi
FROM test
INTERSECT
SELECT abc, def, ghi
FROM TABLE(CAST(coll AS test_coll_typ));
BEGIN
-- Create some rows in our collection
coll.EXTEND(3);
coll(1) := test_typ(2,3,4);
coll(2) := test_typ(1,2,3);
coll(3) := test_typ(3,4,5);
-- Output the duplicates in table "test"
FOR rec_dupes IN cur_dupes LOOP
DBMS_OUTPUT.PUT_LINE(rec_dupes.abc||' '||rec_dupes.def||' '||rec_dupes.ghi);
END LOOP;
END;
The disadvantage is that you now have two more objects in your schema. This might not be a problem if they're there for other reasons too, but it is a bit of overkill perhaps if this is their sole reason for being.

What is the best way to connect MBP 13" - (non retina) to HDMI TV input

...To get Video and Audio? With one cable ...
I'm seeing that the "rocketfish" adapter is not handling the job (from these forums).
I enjoy watching youtube videos, hulu, etc on the big screen through my laptop. The other Windows laptops I'ved had from Sony, HP, Dell, all had HDMI and was easy peasy.
I don't have the patience to buy and return 10 different types of adaters (nor would Best Buy appreciate that)
Thank you!

UI design - what is the best way to allow the user to set some kind of infusion at varying (non periodic) times?

I want to allow the user to specify a curve like this:
Such that some subVI outputs the value A2 when a time variable is within the range R1, A1 when the time variable is within the range R2, and A3 when the time is within the range R3.
My design looks something like this:
With error checking that looks like this:
My question is, is the array based approach optimal? How else could I tackle this?

I think I can summarize the conversation to this point as an answer to the original question (What is the best way ...) -- before starting to write any code, think carefully about what you want to accomplish, and write it down (otherwise known as "Write the Documentation First"). One of the points of a good User Interface is that it doesn't allow users to "make silly mistakes" -- it leads the user "by the hand", restricting the entries to "legal values" and requiring that entries be made in a logical manner.
So if you were going to have a list of Infusions to enter, it makes sense to decide on whether to enter Time Intervals (which are always >0) or Times (which, logically) are always in ascending order. You can (and should) decide which you want (or you could have a control that would let the User decide, but that might be too flexible) and then enforce your "rules".
Suppose you decided on "Intervals" (which seems, to me, to be more User Friendly). After the User has entered the intervals (and you've provided a nice plot of Infusion vs Time), you could allow the User to "split" an Interval, "Remove" an Interval, or "Edit the Infusion" of an Interval, or you could decide to have a simpler "Accept or Start Over" choice -- if you only have a few intervals, the last might be the simplest (and thus the Best) Design Choice.
Spending more time thinking before coding usually pays Big Dividends!

What's the best way to merge, restore or reconstruct iPhoto and Aperture libraries to resolve images that are not found/offline?

Hey there, Apple Support Communities.
To start, I'm working on a MBP Retina 15" with a 2.3GHz i7 processor and 16 GB of RAM. 10GB free on a 256GB SS HD. Attached are two external HDs - one 1TB Western Digital portable drive from 2011, one 2TB Porsche LaCie non-portable drive from 2013; both connected via USB. All photo libraries in question are on the external drives.
I have Aperture 3.5.1 and iPhoto 9.5.1. I prefer to work in Aperture.
The Issue(s)
Over the years, I have accumulated a number of iPhoto libraries and Aperture libraries. At one point, I thought my WD drive was dying so I purchased the LaCie and copied all libraries over the the LaCie drive. (Turns out, there's probably an issue with my USB port reading drives, because I can once again see the WD drive and occasionally I can't see the LaCie drive.)
So now I have old version of some libraries on the WD drive, and new versions on the LaCie drive.
When I was moving things, I ran the software Gemini to de-dupe my iPhoto libraries. Not sure what effect that may have had on my issues.
In my main Aperture library and in some iPhoto libraries, I get the image-not-found badge or exclamation point. I've dug through the hidden Masters folders in various libraries to find the original image. In some cases, I have been able to find the original image, sometimes in a different version of the iPhoto library.
My Question(s)
1. For Aperture libraries that have missing originals, is there some magical way to find them, or have they just disappeared into the oblivion?
2. For iPhoto libraries that have missing originals and I have found the original in another iPhoto library, what is the best way to proceed?
3. Are there quirks to merging iPhoto and Aperture libraries (by using the Import->Library) feature that I should be aware of?
TL;DR: Too many iPhoto and Aperture libraries, and not all the original pictures can be found by the libraries anymore, though some originals still do exist in other libraries. Steps/process to fix?
Thank you! Let me know if you need add'l info to offer advice.
With appreciation,
Christie

That will not be an easy task, Christie.
I am afraid, your cleaning session with Gemini may have actually removed originals. I have never used this duplicate finder tool, but other posters here reported problems. Gemini seems to replace duplicate original files in photo libraries by links, and this way, deleting images can cause the references for other images to break. And Aperture does not follow symbolic links - at least, I could never get it to find original files this way, when I experimented with this.
1. For Aperture libraries that have missing originals, is there some magical way to find them, or have they just disappeared into the oblivion?
You have to find the originals yourself. If you can find them or restore them from a backup, Aperture can reconnect them. The reconnect panel can show you, where the originals are supposed to be, so youcan see the filename and make a Spotlight search.
For iPhoto libraries that have missing originals and I have found the original in another iPhoto library, what is the best way to proceed?
Make a copy of the missing original you found in a folder outside the iPhoto library. You can either open the iPhoto library in Aperture and use "File > Locate Referenced file" to reconnect the originals, or simply reimport them. Then Lift&Stamp all adjustments and metadata to the reimported version.
See this manual page on how to reconnect originals: Aperture 3 User Manual: Working with Referenced Images (the paragraph: Reconnecting Missing or Offline Referenced Images)
Are there quirks to merging iPhoto and Aperture libraries (by using the Import->Library) feature that I should be aware of?
References images will stay referenced, managed will remain managed. You need to unhide all hidden photos in iPhoto - this cannot be done in Aperture.
and not all the original pictures can be found by the libraries anymore, though some originals still do exist in other libraries. Steps/process to fix?
That is probably due to Gemini's replacing duplicate originals by links, and your best cause of action is to fix this before merging the libraries. Reconnecting can be done for your iPhoto libraries in Aperture.

What is the best way to export the data out of BW into a flat file on the S

Hi All,
We are BW 7.01 (EHP 1, Service Pack Level 7).
As part of our BW project scope for our current release, we will be developing certain reports in BW, and for certain reports, the existing legacy reporting system based out of MS Access and the old version of Business Objects Release 2 would be used, with the needed data supplied from the BW system.
What is the best way to export the data out of BW into a flat file on the Server on regular intervals using a process chain?
Thanks in advance,
- Shashi

Hello Shashi,
some comments:
1) An "open hub license" is required for all processes that extract data from BW to a non-SAP system (including APD). Please check with your SAP Account Executive for details.
2) The limitation of 16 key fields is only valid when using open hub for extracting to a DB table. There's no such limitation when writing files.
3) Open hub is the recommended solution since it's the easiest to implement, no programming is required, and you don't have to worry much about scaling with higher data volumes (APD and CRM BAPI are quite different in all of these aspects).
For completeness, here's the most recent documentation which also lists other options:

I have an old 30" apple cinema display (2005) I want to use as a 2nd monitor to a new iMac (2012). I don't just want mirror image of iMac; what's the best way to do this?

I have not bought the iMac yet but will do so very soon and just want to make sure I have what I need to get everything setup including adding the old faithful 2005 30" cinema display. Currently I am driving the old 30" cinema display with a macbook pro also purchased 2005 and happy to say I got a lot of good miles out of this rig. What's the best way to connect the old 30" monitor as a second display for the new generation iMacs?
Other Questions
I can find online new in unopened box a 2012 iMac 27" i7 with 1T Fusion Drive for $1899 no sales tax. This seems like a pretty good deal since I notice the same is available from Apple refurbished for $100 more plus sales tax. I know that they say the Fusion drive is a lot faster on 2013 models but some of the speed tests I reviewed online showed the 2012 i7 and 2013 i7 very close on speed for both storage and processing. Any thoughts?
I don't like changing batteries so I would buy a separate Apple keyboard with numeric pad since it only comes with wireless keyboard. I'm a trackpad enthusiast having been using my macbook pro trackpad with current set up; and I am prepared to buy the Apple trackpad and replace batteries every 2 months but I would greatly prefer USB connection and rechargeable trackpact. I know Logitech makes one so if anyone is using and knows how it compares to Apple's I'm all ears.

What is the best way to work with Word documents in The InDesign CS4???

What is the best way to work with Word documents in InDesign CS4???
David Blatner says to avoid copying and pasting text from Word instead of placing it (Ctrl+D).
How about pasting RTF or Text Document???
I want to make book's layout in ID CS4 and its main feature is that there is the left page with text and the right - with graphics.
So, as I understand to place the text on each page I must create for example 70 Word documents and place each item on 70 left pages???
It loks like wasting time. I sthere another way of making such layout??? What kind????

It's best to place any text.
You can have all of your text in one file and use auto-flow to add threaded text frames and pages as required (Hold down the Shift key when you click the loaded text cursor), but it's a little non-standard to have the thread only on one side of the spread from the auto-flow perspective, so you'll have to set up properly.
This is one case where a master text frame will work to your advantage. On your master page spread, add a text frame to the left page, but not to the right (or at least not threaded to one on the right -- for some other project you might actually want two independent text threads). Hold the loaded cursor over a frame on the left side of a document page and auto-flow. ID will add new spreads as necessary, but only put the text on the left side.

What is the best way to import and edit a large amount of footage?

Hello Apple world,
As a newbie to Final Cut 10 I have a question regarding best ways to import footage. I'll give you a quick run down.
I have a 150 gig of gopro footage that I just hit 'import' to recently (from my external HD), it took around 10 hours to process it all.
Its all under one event, but then somewhat organised into dates etc. But it is very slow. I imported it all at once because it was all footage from the last 6 months of my Whistler/states/fiji trip and want to make a movie out of it, using clips from all over the time, not just in chronological order.
I have the latest mac book pro, 4 gig ram,2.4 GHz i7, 750 hard drive, with nothing else on the computer.
Ive read about creating proxy media, after ive imported, but am still somewhat confused as to the benefit. Does it create duplicates? that will fill up my pretty large HD as it is!
Can you suggest any ways that might make my laptop run a bit faster? Should i delete and work directly from external HD etc etc?
Any suggestions will be greatly appreciated!
Thanks in advance

Hello,
I've just finished shooting what I am considering to be my directorial masterpiece. Shot it on the Canon 5D (1080p, 24fps), and the footage looks amazing. Now I am ready to start editing and have been using premiere lately, but I have yet to figure out the proper pipeline. I want to know the best way to retain resolution before I delve into this project.
My questions:
1) What is the best way to start a new project and import the footage without having to render whilst editing, so as to retain all resolution and originality of the source footage?
2) What is the best way/ codec/ format to export this same footage once editing is complete so as to retain that crisp 1080p for which the 5D is so recognized?
3) What is the best way/ codec/ format to import and export/ render between premiere and after effects? I am speaking mostly of vfx and color correction. I also have some 30fps footage that I intend to slow down in AE and then import into premiere.
I know this is pretty broad, but as a solo filmmaker I really need someone's guidance. I rarely ever finish my films with the same, crisp look as the footage. I need pipeline help, and really appreciate it!
1. Follow the advice above. Also use the Media Browser to import the footage in case you have spanned media files. Import files with the Media Browser.
2. It largely depends on what you wish to ouput to: Blu-ray, web, etc. This FAQ gives the best answer: What are the best export settings?
3. Use the Replace with Adobe After Effects Composition function.

What is the best way to use a SSD for Photoshop/photo editing?

Computer hardware newbie here: I do a significant amount of photo editing work and for a very long time I've experienced Photoshop, Bridge and Photomatix crashing constantly (usually due to insufficient RAM) or just generally taking forever (Bridge took forever to load the thumbnail/preview extractions in a folder full of images, Photoshop took forever to save images and Photomatix took ages to load/merge a set of bracketed photos). Here are the typical error messages I'd get: http://pastebin.com/J9byczse
As a professional photographer, constantly running into that sort of thing is quite aggravating, so to hopefully avoid ever having to deal with that again I invested in a new custom built computer. It's Windows 7 Professional 64 bit with 32GB of RAM and a 240GB SSD; I'm using the 240GB SSD as my boot drive/OS, all of my programs are installed there, and the page file. My photos and data are stored on several HDDs. I have yet to install any of my photo editing software (Photoshop CS6 Extended, Lightroom, Photomatix etc) to the new computer yet since I'd like some advice first.
My basic question is this: what is the best way to take advantage of the SSD (and the computer in general) when it comes to my photo editing software?
Specifically...
1. If I have a folder of photos I'm working on, should I move it to the SSD and then work on them from there in order to take advantage of the speed of the SSD? Would this make any difference in terms of speed if the photos are located on the SSD vs. an internal/external HDD?
2. Most of what I've read online seems to recommend two separate SSDs, one for installing/booting the apps and one for cache/scratch. Does it matter if I use my 240GB SSD for both?
3. This is a fairly new computer and the SSD is already almost half full (102GB used, 120GB free) *WITHOUT* any of my photo editing software installed yet. I'm concerned about how fast that remaining 120 GB may fill up. As it fills up will I lose the speed advantage of the SSD vs. a regular HDD?
4. Sort of similar to #3, but should I bother moving any of my other non-photo editing programs/caches off of the SSD to a HDD and would there be any major difference in the speed/lifespan of the SSD if I did so? It's mostly Firefox and Chrome and their caches that I'm concerned may be a problem if they remain on the SSD.
Thanks for any help!

If you have an SSD you can run the cache and programs on the same drive. However, many recommend a scratch disk size of 100-200 gigs so that will not work here unless you opt for a larger SSD. Otherwise an internal spinner is recommended that does not contain the program files, or idealy any other files that may want to get acessed at same time (only one read/write head per drive).
With 32 gig of RAM you may not need the constant use of the scratch drive unless working on large images with lots of layers. So see no advantage to moving folder to SSD for temp work environment.
From what I read the new crop of SSD do not have the wear problems of the older versions.

What's the best way to handle this?

I'm not sure what APIs/setup to use for this situation:
A company wants to store data projects they do for clients. Each year, the data fields are set (as a result of gov't requirements) and they won't change for any client project for that year. however, the fields required can (and usually do) change every year. So things they require this year, might not be needed the next year and new fields might be introduced.
While there are likely to be many common fields from year to year, there's no way to guarantee which ones will remain consistent. They also want to be able to do searches on the data and fields, for projects within a year and across years.
What's the best framework/API/configuration to handle this? EJB? Simple JDBC? If so, how should the database be handled? Won't it have to constantly create new fields in a table? Or is there another way to handle this?
What's the best way from a "clean architecture" standpoint?

dang, I really have to start over? I finally got all this stuff working again. well, hopefully it won't be as big a pain this time since the data won't be coming from a different machine. After completing the Migration Assistant process, I had to reinput a bunch of serial numbers for apps, reinstall print and mouse drivers, etc... I've finally got the new machine up and running smoothly and now I gotta start over? Sigh.
I was hoping that either I could rename the current account after deleting the other one, or just move everything from one account to the other and then delete the 'RJM' account.
ok, so it sounds like here are the steps I need to take:
- make another full cloned backup of this current machine in Super Duper
- reboot this machine using the advice in the first post, wipe everything clean and reinstall the OS
- create a new account like 'user1' and re-do software update (which is like 2.5 gig worth of stuff) and takes like an hour even on a high speed connection
- then re-do the migration assistant process to the properly named account
- then delete the 'user1' account
does that sound right?
