Exception handeling at different layer!

Hello All,
My apps design has the following layer: JSF(front-end) -> Business Delegates (POJO) -> EJB3 (Session Facade) -> POJO (DAO) -> Hibernate --> DB. Now i am little confused for exception handeling. I have following approaches in mind.
1- Propogate my exceptions from Hibernate all the way to business delegates and handel all of them there. I am not sure this will be a good approach. But it will allow my to have one place to handel all exception.
2- Handel exception at differnet levels. DB related expceptions IN Daos, Logic and EJB related exceptions in Bussiness Delegates.
Please suggest me better of these or purpose a new suggestion.
Thanks

generally when something blows in a DAO, you want your application to know about it. Otherwise you can get into a situation like this:
1) business logic calls DAO
2) DAO throws and handles its own exception
3) business logic goes on to work on data in an unknown state
That doesn't work. At 3) you want to catch the exception, log it and possibly roll back an entire transaction, effectively ending the business logic and possibly going on to some error handling routine, like showing an error page.

How come, that the shadow of an object on one layer effects the view of an image, that is on a different layer

one layer has a shadow - on a second layer I have my image - how come, that the image-view is effected by the shadow of an object of a different layer? is this only a view-effect or does this effects the prints as well? if so, how can I change it?
thanks for advice!

Basic rule is that transparent object affects other objects behind it. So if you bring some object to front of transparent object (or upper layer), transparency flatteners doesn´t flatten it during transparency flattening. There are some exceptions to that rule, but I almost categorize those as bugs...
Use Window>Output>Flattener Preview panel to see which objects are affected...
If you export PDF, it makes a difference if you use PDF1.3 as compatibility. Using that PDF-version triggers Transparency Flattener and resulting PDF has no live transparency. All the other compatibility options preserve live transparencies....
http://www.adobe.com/products/creativesuite/pdfs/dgt.pdf is quite good white paper about transparencies in CS softwares, it´s a bit old but most of the things have not changed since CS2...

OBIEE 11.1.1.6 different layer hierarchies

Hi experts,
I want to know whether the following layout is implemented. How to create different layer hierarchy in BMM in OBIEE 11.1.1.6?
If it does work , I want to drag this hierarchy into presentation. Please help me as soon as possible. Thanks.
For example:
Presentation Hierarchy
Total
---Region
-----District
---------Brand
-------------Product Type
-----------------Product Detail

Hi SPowell42,
I am using OBIEE 11.1.1.6 to design and develop anything.
I have searched some related help information in RPD, and found 'modeling dimensions with multiple hierarchies in the presentation layer ' title which introduced some simple hierarchy information,such as
Country
--Region
-----City
-------Supplies
-------------Product
-------------------Product detail.
I am not sure whether it can do different layer hieiarchy in hieiarchy persenation. Maybe the sample column data stored in one table, however, it is my assumption.

IS it possible to print image name/Path in a different layer in my existing indesign file??

I want to print my image name and its path in a different layer in my indesign file.. Is it possible through script? Can any one help me how can I do this..

Hi Tom,
I'm pretty sure the IPTC data gets completely consumed inside an Adobe
PDF file, even if the original images have this metadata or extended
data (XMP) information. In other words, they do not make it through.
Try downloading a copy of Enfocus Pitstop - I know you can link to an
original authoring document (InDesign/Quark) through the CertifiedPDF
route but you cannot display the image name?
This is an interesting topic.

Hi Arik,
Thanks for your reply.
Could you please share some document or link from Oracle for this problem explanation and solution because I was unable to find this on the internet.
Also now we are facing issues with SOAINFRA Schema. Can this be even part of the earlier problem that we faced for MDS Schema.
The error are detailed below:
Caused By: java.sql.SQLException: ORA-01654: unable to extend index DEV_SOAINFRA.CI_CREATION_DATE by 128 in tablespace DEV_SOAINFRA
Not fatal connection error ... not retrying: class com.collaxa.cube.engine.EngineException: Global retry rollback fault thrown.
The current JTA transaction is aborting due to an user rollback fault being thrown. The upstream component should retry in a new JTA transaction upon catching this fault.
This exception was caused by a global retry fault being thrown from downstream component. The user had directed the BPEL engine to roll back the current JTA transaction and retry within new JTA transactions for the specified number of times and retry interval.
There is no action recommended.
Any help will be appreciated.

RE: moving a layer mask to a different layer.

Is there a way to move a layer mask from one adjustment layer to another adjustment layer (within the same file), without removing the mask from its original layer? (I can move a mask to a different layer by clicking and dragging the thumbnail, but the mask then disappears from its layer of origin). I'm using Ps CS5 on Windows XP.

Vinsolo,
I tried the alt-drag and it works; thank you for the info. Would this technique also work to move a layer mask to a layer in a different file?

Sublayers display different layer color from Layer

Can anyone explain to me why sublayers take on different layer colors from the parent layer color? This especially becomes problematic with large files that have lots of layers. As I start grouping and organizing layers, the layer colors become jumbled and it becomes difficult to read. I would expect when I drag a layer into another layer, the new child layer would take on the color of it's parent. Any suggestions on how to maintain layer colors w/out having to open up the layer options each time and choose the parent color?

This is "as designed" it has been this way for the last 10 centuries or so... Sorry, no way around it, even if it seems illogical. Perhaps there is some script out thgere that can mass-change such attributes....

Is it Possible to move the Dropdown Menu to a different layer than the rest of the menu?

For design reasons I want the dropdown part of my menu to appear as though it is coming out from underneath the banner of the menu. The best way I can figure to do that is to have the dropdown part of the menu (that occurs on rollover) be placed on a separate layer from the main banner menu. Is this possible? I have tried unlocking everything and moving that part to another layer and haven't been successful. Please help this gal out! Thank you!

I'm still confused as to how I can do this exactly. I have used the tool tip widget to create my own drop down menus. However, I cannot put the trigger point into a different layer than the layer with the drop down menu. How can I make the actual word "accommodations" into the trigger point for this menu? I tried moving the trigger point from the widget over the Accommodations, but in order for the drop down to come out from under the banner, the trigger is under it as well. I've also tried ungrouping them, but I am not successful. Please give me further detail as to how this works!

Transfer rotoscope path to different layer

A novice rotoscoper, I got a little confused from having read and watched tutorials with several diffeent styles of rotoscoping.
Some said to use a layer in between path and actual subject layer with the eyeball turned off. Then lock the actual target layer so as not to move it around inadvertantly.
I may have that confused a bit... if so, it not the tutorials doing but mine.
Cutting to the chase; I have a solid light grey layer with the opacity turned down to 1. above a footage layer of my great grandson doing his first zombie walk.
I spent a lot of time getting a mask to follow his little head in his trek across the floor. Now I wanted to transfer the mask path points over to the target footage layer. I clicked the footage layer with the pen tool to get a mask started, then with focus on the grey layer/Mask/mask path (all the points are lit up so selected) and copy... then to the footage layer Mask/Mask path - paste. So far so good.
But somehow I must have moved either the grey solid layer or the footage layer sometime during all the pulling and hauling.so the mask misses the head in a perfect offset all the way thru. The attached screen shot illustrates it well. The first one shows the mask on the grey layer, the second on the footage layer.
I tried lining up the layers by setting the `position' parameters the same, also by just eyeballing the crosshair thing that shows the center of each layer.
Trouble is I can't find a way to see the crosshair from the one layer as soon as I focus on the other to move it. Ditto for the path itself. Soon as focus changes the path does to. I may be going the opposite way of what I should, but tried it both ways with both layers and am just not getting how to get it right.
I know I can just do it over, and that isn't really a problem since I can clearly use the practice. But I feel like there must be a a clearcut way to match up a layers position to a path.
At this point I've thoroughly confused the heck out of myself and would like to hear someone lay out how to get two layers to match up

Haa, the footage layer is turned on but the solid layer above was
set to 1% opacity.. with the eyeball off. cranking that up 100 fixed
it. Now I can see the babies head, and the rest is masked out as
expected.
You'd
think the opacity setting on the solid layer would not matter if the
layer eyeball is off anyway, but apparently it does. If I scroll the
opacity up and down with the layer eyeball off, the babies head
appears at higher percentages and disappears below 10 or so.
If you think about it, it makes sense.
A track matte set to "alpha" applies the opacity value of each pixel in the layer directly above to current layer. So, if Opacity for that layer is 1 per cent, that affects the opacity value of all pixels. Leaving it at 100 per cent, means that fully opaque pixels are applied as fully opaque, and fully transparent pxiels as fully transparent.
The visibily control (eyeball) for the layer above is turned off aumatically (if it's not already off) as soon as you set a track matte mode. So, the layer is "seen" for the operation regardless of the visibiliy status.
The column is headed with `T' and when you check it, it says `preserve transparency'. I don't quite get what that is for.
That's called "Preserve Underlying Transparency", and it's a very convenient option... but I am surprised by how many people enable it without knowing what it does. It's not the first time someone gets bitten by it
And what it does is... this layer (the one with the switch turned on) only exists in areas that are not transparent, when taking into account the combination of all layers below. Example: if you have three circles placed in different places, and then create a large text layer and enable this switch, text will only exist in places that match the circles underneath.
More info in Preserve underlying transparency during compositing, in After Effects Help on the web.
Another aspect of this: I wanted to rotoscope the whole body... so as to be able to insert it on differnet backgrounds.
I
could use some ideas on that too. I started with just the head to get
an idea of how its done... but I'm guessing it might be easiest done by
taking several masks to enclose various chunks of the babies body. Is
that how its done?
There are many valid approaches, and whatever works for you is fine. But you can be happy to learn that many experienced roto artists suggest doing exactly as you just described
I really recommend Mark Christiansen's book After Effects CS4 Visual Effects and Compositing Studio Techniques. It has a lot of useful information on roto work with AE.

Best Practice - When to put things on a different layer?

I'm designing a simple website that includes a FLVPlayer
component, some ComoBox components that control the player, and
some text. Is there a technical reason why the player, the
comboboxes and the text should each be on different layers, or is
it more a matter of housekeeping? Is there a rule of thumb that
indicates when a new layer should be used for something?
Thanks

I use them for organization, most of the time. When tweening
symbols on the stage there can only be one symbol on the layer or
it will not work. There should be a layer specifically for
actionscript as well.

Weird problem: different layer sizes

This is not the first time I encountered this problem but here it goes again:
I have copied one layer several times and applied different filters. I turned on fixed resolution and had temporarily grouped and ungrouped three of the layers. When I added a fourth one and tried to export, the last one appears slightly bigger and off centre... Any explanation for this.
I solved the problem by importing the whole thing into FCE and exporting the movie there - just interested what causes this weirdness...

See this thread:
http://forums.adobe.com/message/3905911#3905911
"There is an issue with Encore layer breaks so most probably this is what is causing the problem.In some cases Encore places an extra chapter on the timeline at the place where the layer break occurs.This causes subsequent chapters to be incremented by 1."
The original poster in that thread fixed the problem (which may not be precisely your problem) by putting the manual layer break on one of his chapters.

Apply adjustment layer to different layer?

Warning: I know just enough to be dangerous. And barely enough to explain myself. I've just managed to create exactly the effect I want, but...
I have a layer (HEADER) to which I applied adjustment layers (curves and levels) using "Use Previous Layer to Create Clipping Mask". So now, above my HEADER layer, I have the adjustment layers (with linked masks) with the little black right-angle arrow pointing down to my HEADER layer.
Is it possible to copy these adjustment layers and apply them to a second layer (e.g. FOOTER)?

Shoot, I knew someone would hone in on those names. This is an image originally created by a design agency. "Header" and "Footer" refer to "swooshes" across the top and bottom of the image. So ignore the meaning of the names...
And I'm sure I'm overlooking something really simple... OK, I have the HEADER layer at the top of my layer stack. Above it are the Curves and Levels adjustment layers (actually there is a Brightness/Contrast adjustment layer also), with the little black arrows pointing down indicating that the adjustment layer is applied ONLY to the Header layer. (At least I think that's what those black arrows mean.) Cool.
Then there are about five more layers of other stuff. The adjustment layers don't affect them. Cool.
Then there is the Footer layer. There are several more layers below the Footer layer. I would like to take all three of those aforementioned adjustment layers and apply them to the Footer layer also. So I duplicate, for starters, the Curves layer. "Curves copy" appears above the original, with it's little black down-arrow. But when I drag it to be above the FOOTER layer, it loses its little black arrow and is now applied not only to the FOOTER layer but also to all layers below it. Not cool.
Does that help? Thanks for taking me on...

Execute Immediate - Exception handelling

Hi Guys,
I have the following code that loops through and populates the execute immediate statement with local variables from the cursor.
The only problem is when the statement fails and goes to the exception, I want the local variable to be cleared. This is causing me problems becuase it is populating incorrect data where it fails.
LOOP
BEGIN
EXECUTE IMMEDIATE 'SELECT MAX(REC_EXTRACT_DATE) FROM '
|| rg_e_date.source_name
INTO lv_extract_date;
EXECUTE IMMEDIATE 'SELECT count(*) FROM '
|| rg_e_date.source_name
|| '
where rec_current_flag = ''Y'''
INTO lv_num_of_records;
EXCEPTION
WHEN OTHERS
THEN
NULL;
END;
Any help would be apprechiated.
Cheers

I'm guessing you don't know because you have a generic exception catch there (that's bad).
Also, if you aren't aware, this is a 'bad' method of programming in Oracle (i'm assuming you are storing SQL in database tables, or some other such fashion). It won't be good for performance if you need this application to be quick and scalable. Just a word of caution.

Exception handeling

Hiii,I m facing a problem in exception handling. I have created a chat application which recieve the information from web user and then put that information in a link and hits that link via URL object.thus an user recieve the message on his cell phone as SMS.but the problem is if the link is down then when my application open the connection on the link it waits to connect and after some time it throws exception whic is connection timed out exception. the time it waits to throw exception involves 6/7 more request on server thus a large amount of threads which are not fullfilled are created and my OS windows 2000 hangs the application with exception can not create more native threads.is there any way that i can handle this situation??Thanks

If you simply want to make the connect timeout more quickly, you could use a Timer and TimerTask to interrupt the thread.
Alternatively, use java.nio.channels.SocketChannel to achieve the same effect using a selector.
I assume that you have some sort of error handling for the case where the connection times out. You could bypass further connection attempts for a while with the same error, rather than trying again.
Something along the lines of:
static long nextConnectTryTime;
    synchronized(this.getClass())
        // If connection already failed recently, then don't bother
        // trying again - just assume it'll fail.
        if(System.currentTimeMillis() < nextConnectTryTime)
            ... error handling.
        else try
            mySocket.connect(address);
            nextConnectTryTime = 0; // Allow more connections.
        catch (IOException ex)
            // Bad - don't try again for 60 seconds.
            nextConnectTryTime = System.currentTimeMillis() + 60000;
            ... error handling.
    }You catch my drift?
Of course, this somewhat simplistic approach serializes connections. There are more complicated schemes that would allow a number of concurrent connection attemps. It's a design call as to whether that level of complexity is justified.
[And if anybody tells me that the above won't compile.........!]

Cut and paste to a different layer on cs5

Hi,
As i mentioned on subject, I would like to simply cut an object from layer_01 to layer_02 on cs5 Illustrator. When I do that, Illustrator brings the layer that belongs to the object with it. I do not want this. I want to bring the object itself not the layer. This looks like a subtle detail although it saves a lot minutes for me.
I used to easily do that without any difficulty with cs4-3-2-1 but with cs5 i guess there is another step i am missing.
Helps will be appreciated.
Omer

You're not missing anything it works fine here on a MacPro OS 10.6.5 AI CS5. You are highlighting the layer first? You can also drag the path to the layer you want in the layers panel also works fine.
Try this
PC
1. Quit Illustrator.
2. Rename the AIPrefs file (for example, to AIPrefs.old) in the Users/(user)/AppData/Roaming/Adobe/Adobe Illustrator CS3 Settings folder.
3. Start Illustrator. Illustrator creates a new preferences file.
Mac
1. Quit Illustrator.
2.Go to User/username/Library/Preferences/ Adobe illustrator CS4 Settings and trash the settings folder, the whole folder not just the contents of the folder..
3. Start Illustrator. Illustrator creates a new preferences file.
