Problems with image field and java

Hi, i´m a beginner user of Adobe LiveCycle Designer, i create a form and i fill the text fields with a Java code, but when i try to dinamically assign a image on the image field of my form it doesn´t work, someone have any idea of whats happening or how can i manipulate the image field from Java code? thanks

Session data will only last as long as the servlet container allows. In most cases (eg Tomcat) this defaults to about 30 minutes, but can be changed. Check that the session timeout configuration in your servlet container hasn't been set to "never timeout".
Even if it had, I would have expected OutOfMemory errors rather than degrading performance. Although if the max heap size of the JVM has been set to a level higher than the RAM on the machine you could be getting excess page file usage.
This probably wouldn't put CPU utilization at 99% though.. I suspect this is a code related problem.
My best guess is one of two reasons:
1. Somewhere in your code, or someone elses, there is a loop that never ends.
2. There is a bug in the servlet container.
I don't know which servlet container you are using, but I have used Tomcat extensively and never seen this behaviour.
In terms of solving this problem, that's a tough one. I would try running the entire application within a profiling tool to see which threads are clogging up the processor. The Eclipse java IDE has a plugin called Eclipse Profiler which will allow you to track the utilization of code right down to the method level.
If it were me, I'd be running the entire web application with a profiler like Eclipse Profiler and waiting for it to start clogging, then see who the guilty code is.

Problems with Image Field Table in Adobe Forms

Hello,
I have a desgined a Adobe Form(Print Only) in the Adobe Desinger in NWDS.
The form layout contains a table of images in 2 columns and 3 rows. Every Column has a Image Field and a TextField displaying the Image URL.
The URL of this image is passed at runtime.
The problem is that when the form is rendered, All the Columns have the same image which is the URL in the first row first column. However the text field displays the correct URL.
Is this some known bug in the Adobe Forms, or I am missing some property.
Regards,
Shubham

Hi,
The solution was to put the following code in the initialize event of the image field.
this.value.image.href = <Photoimagepath>.rawValue;
Where <Photoimagepath> is the image path.

Problem with image scaling and aligning to the MC bounds

HI
I have problem with my custom class.
For example if image is loaded into the
holder_mc inside of
loader_mc, and if the loaded image is bigger than the
loader_mc, then I want it to scale it down to match
loader_mc bounds.
It is something similar to Loader class...
I've copied this code outside of Loader.as file and modifyed
it, but its not working...
I'd realy appreciate that if you could find any mistake or
any code similar to this...
Thanks in advance and sorry for my bad english...

InDesign Transparency Effects - Problems with Image Quality and File Size

Hello,
We are experiencing new problems exporting InDesign files to PDF.
To summarize, though our largest workflow is to create files for offset printing, we also deliver our work to PDF for mounting on a website so our clients can download directly from the web. Our new problem is Transparency Effects, and creating a PDF that will both have a high quality (or resolution), and be a small file size.
We are working with multiple page documents (24 to 48 pages), and would very much like to work with InDesign Transparency Effects. However, after spending much time testing a variety of PDF types, we are finding there is a radical difference between quality and file size. I was curious if anyone has had these problems, and if there is a simple answer. InDesign is an incredible program that allows us to design on the fly with Transparency Effects, but, if we are going to experience these problems, we will have to eliminate these wonderful tools.
Can you help me or lead me to information online that will help.
Thank you,
Lain

Please don't post in multiple forums. Your question has nothing to do with the PDF language and specifications, but rather PDF workflow or InDesign. I've responded to your other posting and am closing this thread.

Having a problem with image IO and drawing image

My question did not come out on the other posting. I am getting them image from a JPanel. I then convert the image into a renderedimage. Use the ImageIO.write method to convert to png format. I don't want to save the image on the local disk so it is writted to a ByteArrayOutputStream. I get the bytes from this and insert this into a blob field type.
Then to paint the image onto the JPanel I try two methods to paint it on to the JPanel. I set the JPanel to be the width and size of the image. But I am getting a null pointer exception and I can't figure out why. If anyone could give me any suggestions I would really appreciate it.
rImage = convertToRenderedImage(draw.drawPanel.offScreen, width11, drawPanelHeight, type);
try{
bo = new ByteArrayOutputStream();
ImageIO.write(rImage, "png", bo);
imageBytes = bo.toByteArray();
}catch(IOException iox3)
System.err.println(iox3);
PreparedStatement statement12 = connection.prepareStatement(
"INSERT INTO feed VALUES(?,?,?,?,?,?);");
statement12.setBytes(2, imageBytes);
icon = new ImageIcon(rs.getBytes("file"));
image = icon.getImage();
//base is the JPanel
Graphics g2d = base.getGraphics();
bytes = rs.getBytes("file");
bInput = new ByteArrayInputStream(bytes);
try
bImage = ImageIO.read(bInput);
catch(IOException e21)
System.out.println("Error in imageIO transformation");
//image is Image and bimage is bufferedimage
image = bImage;
Graphics g2d = base.getGraphics();
g2d.drawImage(image, 0, 0, base);
g2d.drawImage(image, 0, 0, base);

Would it be possible for you to send out a small runnable testcase that I could try out with?
Thanks,
Kannan

Problems with Server utilization and java

Dear all,
I am developing a page in JSP and make use of javabean to transfer data from one page to another within a session. The data in javabean are never been erased.
The problem is when the server runs for a long period of time, it becomes slower and the utilization is 99%. What happen is it and how can I solve it? Is it related to the memory allocated by the java?

Session data will only last as long as the servlet container allows. In most cases (eg Tomcat) this defaults to about 30 minutes, but can be changed. Check that the session timeout configuration in your servlet container hasn't been set to "never timeout".
Even if it had, I would have expected OutOfMemory errors rather than degrading performance. Although if the max heap size of the JVM has been set to a level higher than the RAM on the machine you could be getting excess page file usage.

A problem with autocomplete field and mouse used to change input focus

I have a question about a Text field "Autocomplete".
I uses this to enter Email addresses in my APEX application. It works fine only if you use "enter" or "tab" to move to the next field. Not if you use the mouse...
Example : I start to look for my Email address by typing my name : jean-j ... My full Email address is shown.
If I press enter or tab, the field is filled with me upper Email address : [email protected]
BUT if I click with the mouse on the next field, the field is filled with : [email protected] !!!
How can I avoid this behavior?

Should have added that the "automatic fill" is enabled.

Problems with SQL*Loader and java Runtime

Hi. I'm trying to start SQL*Loader on Oracle 8 by using Runtime class in this way:
try{
Process p = Runtime.getRuntime().exec( "c:\oracle\ora81\bin\sqlldr.exe parfile=c:\parfile\carica.par" );
/*If i insert this line my application never stops*/
p.waitFor();
}catch( Exception e ){
. I have seen that if lines to insert are less then 400 all works very fine, but if lines number is greater than 400, all data go in my tables but my log file is opened always in writing.Can anyone tell me why?
Thanks

Just a note if the executable "sqlldr.exe" does not stop (quit running) by itself the p.waitFor() will wait for ever.

Experiencing problem with image display in LR5

I have an intermittent problem with images displaying and exporting in LR. It just began a couple of months ago and is totally random - will do it with RAW (CR2) or JPG. It displays this way in all modules - Library, Develop, Slideshow....The image displays fine in a non-Adobe image viewer (Faststone or Windows Viewer). I've reloaded LR5 and PSCC and is still persists. I know the image file is fine. It also has begun effecting older images that were showing up just fine a while ago. I just loaded about 200 images and maybe 3 or so have this viewing problem in LR & PS. Has anyone else experienced it and have a suggested fix? My graphics card has the latest drivers and shows no problems with other applications. Here is the same image - one a jpg export from Lighroom, the other a save as jpg from Faststone. HELP!

This is almost always a hardware problem, causing corruption of the file. The difference you see between Lightroom and other software is that Lightroom is accessing the full RAW image, while the other software is trying to read the embedded JPG preview.
To figure out exactly what hardware is the problem, you need to try different transmission paths and hardware ... different camera cards, different card readers or USB cables/USB ports, different hard disks, etc. Eventually you should be able to isolate the problem.

Copy and Paste Problems with Images

I'm having the strangest problems with images. I copy an image off of the web for one of my art history classes and I go to paste into another program but, whether it's Keynote, Powerpoint, Photoshop, or Graphic Converter, something always goes wrong: the images definitely lose some of their quality, become brighter in appearance, and get jagged on the edges. This is starting to drive me nuts, especially since it never happened in 10.4 on my iBook G4. Any suggestions?

Make it an 8-bit file (Image menu > mode).

My daughter's older Ipod Touch is having a problem with images becoming pixilated when taken from an e-mail and placed into her camera roll. ( She wants to put on Instagram ) Any help?

My daughter's older Ipod Touch is having a problem with images becoming pixilated when taken from an e-mail and placed into her camera roll. ( She wants to put on Instagram ) Any help?

I think that may be a consequence of the email provider she is using. Some services (AOL is one example) inspect and modify email attachments, particularly photos, resulting in reduced resolution compared to the email that was sent.
The iPod does not do this. The resolution of the picture in the email she receives will be identical to what is imported.

Problem with Image.createImage()

Hi all!
I'm writing a simple midlet just to display an image on the screen and I'm having some problems with Image.createImage()
Here is my code
Image bg_img;
ImageItem imageItem1;
imageItem1 = new ImageItem("", null,ImageItem.LAYOUT_DEFAULT, "");
try{
bg_img = Image.createImage("/image.png");
imageItem1.setImage(bg_img);
catch(java.io.IOException e){
e.printStackTrace();
I'm getting an exception on bg_img = Image.createImage("/image.png");
I can't understand what is it...:(
I know for sure that the problem is not "file not found"
Any one can help me???

If you are catching IOException, then u may have problem with ur image path. "image not found on the specified path." if ur image is not in the current directiry then put it into current directory. otherwise, If u are using resouce folder and it is already included into the resouce path, then put ur image in that folder..try this..
Still not get, then please give some detail about ur development toolkit. and ur apllication packaging scheem. are you using ANT?

Problems with .ARW files and auto toning

problems with .ARW files and auto toning
let me try to explain this because this has happened in past and never found a way to resolve but i lived with it
now that I have a Sony A7R the problem is more serious
Firstly i take pride it making the picture happen all in camera, i use DRO lvl 5 to get enough light, like when i'm shooting at dusk. DRO its like doing HDR but in a single file, it lightens the darks. in my camera i'm happy with results
but when I upload them to lightroom, they come out near black.
allow me to explain
lets say I import 100 images
i double check my preferences and everything is UNCHECKED when it comes to importing options, there is no auto toning, nothing.
as the images import i see a preview in the thumbnail which looks fine.
i double click on one to enlarge it, hence leave grid view.
for a brief 1 or 2 seconds, i see the full image in all its glory but than lightroom does something funny, it darkens the image
one by one as it inspects each image, if it was a DRO image it makes it too dark.
to make this clear, the image is perfect as it was in the beginning but after a few seconds lightroom for some reason thinks it needs to correct it.
how to prevent lightroom from doing this, i want the image exactly as it is, why must lightroom apply a correction>?
i think it has to do something with interpreting the raw file and lightroom applies its own algorithm.
but here is what i dont get.....before lightroom makes the change i'm able to witness the picture exactly as it was taken and want it unchanged..
now i have to tweak each file or find a profile for it which is added work.
any ideas how to prevent lightroom from ruining my images and just leave them as they were when first detected...
there are 2 phases...one is when it originally imports and they look fine
second is scanning each image and applying some kind of toning which darkens it too much.
thanks for the help

sorry thats the auto reply message from yahoo email.
i've disabled it now
thing is, there is no DRO jpg to download from the camera
its only ARW. so my understanding is when i use DRO setting, the camera makes changes to the ARW than lightroom somehow reads this from the ARW.
but then sadly reverts it to no DRO settings.
because i notice if i take normal picture in raw mode its dark but if i apply dro to it, it comes out brighter, yet when i d/l the image from camera to lightroom, which is an ARW - there are no jpgs. lightroom decides to mess it up
so in reality there is no point in using DRO because when i upload it lightroom removes it.
is there a way to tell lightroom to preserve the jpg preview as it first sees it.
its just lame, picture appears perfect...than lightroom does something, than bam, its ruined,.
what do i need to do to prevent lightroom from ruining the image? if it was good in the first place.

I have upgraded Apple Aperture from version 2 to version 3 and I'm having a problem with the "Highlights and Shadows" adjustment. According to the user's manual, I should have access to an advanced disclosure triangle which would allow me to adjust mid contrast, colour, radius, high tonal width and low tonal width.
If anyone has any suggestions as to how to access this advanced section, I'd be most grateful.

Hi David-
The advanced adjustments in the Highlights & Shadows tool were combined into the "Mid Contrast" slider in Aperture 3.3 and later. If you have any images in your library that were processed in a version of Aperture before 3.3, there will be an Upgrade button in the Highlights & Shadows tool in the upper right, and the controls you asked about under the Advanced section. Clicking the Upgrade button will re-render the photo using the new version of Highlights & Shadows, and the Advanced section will be replaced with the new Mid Contrast slider. With the new version from 3.3 you probably don't need the Advanced slider, but if you want to use the older version you can download it from this page:

Problem with the MenuBar and how can i delete a own component out of the storage

Hello,
I opened this thread in the category "Flex Builder 2", but
under this category my questions fit better.
I have a problem with the MenuBar and a question to delete a
component out of storage.
1. We have implemented the MenuBar, which was filled
dynamically with XML data.
Sporadically it will appear following fault, if we "mousover"
the root layer.
RangeError: Error #2006: Der angegebene Index liegt
außerhalb des zulässigen Bereichs.
at flash.display::DisplayObjectContainer/addChildAt()
at mx.managers::SystemManager/
http://www.adobe.com/2006/flex/mx/internal::rawChildren_addChildAt()
at mx.managers::SystemManager/addChild()
at mx.managers::PopUpManager$/addPopUp()
at mx.controls::Menu/show()
at mx.controls::MenuBar/::showMenu()
at mx.controls::MenuBar/::mouseOverHandler()
Here a abrid ged version of our XML to create the MenuBar:
<Menuebar>
<menu label="Artikel">
<menu label="Artikel anlegen" data="new_article" />
<menu label="Artikel bearbeiten" data="edit_article" />
<menu label="Verpackung">
<menu label="Verpackung anlegen" data="new_package" />
<menu label="Verpackung bearbeiten" data="edit_package"
/>
</menu>
<menu label="Materialgruppe">
<menu label="Materialgruppe anlegen"
data="new_materialgroup" />
<menu label="Materialgruppe bearbeiten"
data="edit_materialgroup" />
</menu>
</menu>
</Menuebar>
It is a well-formed XML.
2. Delete a component out of storage
We have some own components (basically forms), which will be
created and shown by an construct e.g.
var myComponent : T_Component = new T_Component ;
this.addChild(myComponent)
Some of our forms will be created in an popup. On every call
of the popup, we lost 5 mb or more, all childs on the windows will
be removed by formname.removeAllChild();
What cann we do, that the garbage collector will dispose this
objects.
Is there a way to show all objects with references (NOT
NULL)?
I have read in the Flex Help, that
this.removeChild(myComponent) not delete the form and/or object out
of the storage.
Rather the object must be destroyed.
It is sufficient to call delete(myComponent) about remove
this object out of the storage as the case may be that the
garbage-collector remove this object at any time?
Or how can I destroy a component correctly. What happens with
the widgets on this component e.g. input fields or datagrids?
Are they also being deleted?
Thanks for your help.
Matze

If you mena the "photo Library" then you cannot delete it.
This is how iphone handles photos. There are not two copies. There a re simply two places from which to access the same photos. ALL photos synced to iphone can be accessed via Photo Library. Those same pics can be accessed via their individual folder.
