Thumbnail image creation problem in JSP

Hi,
Can you tell me, how can i create/show thumb view image in web browser from dynamic path not web root directory.
For Example: In server PC i have an image in D:\test.jpg. I want to show this image in browser. I am using Tomcat 6.0 server. Your help will be highly appreciated..
Thanks
Ismail

Probably the easiest thing is not to use Tomcat at all (unless you're using only Tomcat and not Apache as the web server). Using whatever build tool you're using to deploy content to your web site (e.g., Ant), create a thumbnail in an offline, deploy-time process. Then copy the image to a designated location under your docroot (e.g., /images/thumbnails/).

Strange Image creation Problem

hi@all
Just now i got a problem with Image creation.
Alert a;
try {
Image m = Image.createImage("/" +Words[CurrentPage*8+i]+".jpg");
a = new Alert(Words[CurrentPage*8+i], "", m, AlertType.INFO);
a.setTimeout(Alert.FOREVER);
display.setCurrent(a);
     } catch (IOException e) {
                    e.printStackTrace();
then i got an exeption as following:
java.io.IOException
     at javax.microedition.lcdui.ImmutableImage.getImageFromStream(+15)
     at javax.microedition.lcdui.ImmutableImage.<init>(+20)

I put the images into directory res, and when i print out the image path, it is correct. I rewrite
Image m = Image.createImage("/" +Words[CurrentPage*8+i]+".jpg");
like this Image m = Image.createImage("/myImage.jpg"); then it works!
I can not find any clue to solve this problem, totally confused.
Can anyone help me?
Thank u all in advance!!!!

Well, assuming this is an honest question then you need to go to the apple icon top left, click it, then click system preferences from the drop down, and then select energy saver from the menu that appears. You can adjust how long it takes before your mac automatically switches off your display there.
I don't really see how posting in the Developer forums is relevant for basic tech support. Unless of course you're doing so to highlight the stupidity of my question.

Possible Fix for Disc Image Creation Problems

I've noticed a number of posts describing problems similar to the one I had: with my first session with iDVD5, I tried creating an .img disc image (thanks to Apple, btw, for building that function in -- and for the new progress bars!), but it hung up all night long on the "Burn" task, and I had to force quit, leaving me with no image at all.
I used disk image burning exclusively in iDVD4, because it allowed me to preview the result before committing it to a physical burn and prevented coaster-burning if something went wrong. I had had buffer problems when burning directly from iDVD -- but never with Disk Utility.
Of course, in iDVD4, you cannot just burn a disk image using the app. Most are aware that using "Hurz" and "Pfurz" (see posts under iDVD4) provided a great workaround, however, and that's what I used.
Well, it occurred to me that perhaps Hurz and Pfurz -- which basically interfered with iDVD4 to the user's advantage -- ought NOT to be in play with iDVD5. So I removed them from my user folder, et voila -- the very next time I tried the disk image function in iDVD5 (with the same project), it worked perfectly.
But I can only SUSPECT that this was the solution, unfortunately, because of the fact that an automated maintenance script had repaird my permissions in the meantime. The problem might have been permission troubles resulting from installation.
I do know this: removing Hurz and Pfurz and repairing the permissions worked for me. Hope it does for some others as well!

Thanks, Len. I kind of wish Apple would make a bigger deal of this. Repairing permissions fixes ALL KINDS OF THINGS! And it is a VERY good idea to do it regularly.
Like you, I do it once a week, using a wonderful freeware utililty called Onyx (search MacWorld or Google for it), which has a number of advantages over Disk Utility.
In the first place, it will execute all the maintenance scripts as well. You might know that OSX has a number of scripts it runs in the background for maintenance, some daily, some weekly, and some monthly. But they are generally set to run late at night, which means you need to leave the computer ON and AWAKE. I don't do this as much as I should, so running Onyx ensures that these scripts get run. Since using Onyx, I have NEVER had a crash.
Secondly, I can schedule it to do all this automatically, which is great - because I'm getting old . . . and I forget things. . . .

OffScreen image creation problem

Hi everyone,
Actually I am programming some calsses that allow me to modelize different SpotLights (Cercle(Color, CenterCoordinates, Radius) ) and their sorrounded halo (Cercle(Color, CenterCoordinates, Radius)).
I am planning to creat each spotLight and its halo off-screen and save it as .jpg file in a data base or a directory.
My question is: how can I create these images without using any JComponet (Frame, panel or etc). I just want to create them in VM and save them as an image file so I can use them later on!
Thank you for helping and if u need more information to solve this problem I would be happy to cooperate.

Create a BufferedImage.
The BufferedImage has a Graphics2D object, and you can draw the circles on the graphics object.
Then you can convert the buffered image to a JPG file.

Image creation problem

I am writing a servlet that loads an image like this.
     public static BufferedImage readAsBufferedImage(String filename)
          try {
          FileInputStream fis = new FileInputStream(filename);
          JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder(fis);
          BufferedImage bi = decoder.decodeAsBufferedImage();
          rast = decoder.decodeAsRaster();
          return bi;
          catch(Exception e) {
e.printStackTrace();
return null;
I then reduce the colors of the image to 256, outputing a pixel array then generating a bufferedimage
from the pixels. The code below fails and throws a java.lang.ArrayIndexOutOfBoundsException.
Can anyone explain why this occures.
public void setImage(int w, int h, int pix[])
//TYPE_INT_BGR TYPE_BYTE_INDEXED
     try{
     BufferedImage bim = new BufferedImage(w,h,BufferedImage.TYPE_INT_BGR );
     bim.getRaster().setPixels(0,0,w,h,pix); //this is where it fails
     gbim = bim;
     catch(Exception e)
          e.printStackTrace();
I then use the ACME classes to write a gif file.

Are you trying to convert a JPEG image to a GIF image
or something kinda of that

Automatic creation of thumbnail image in BC4J App

I have created a BC4J application using the default wizards that displays the content of the following table:
CREATE TABLE EMPLOYEE_PHOTO (
ID NUMBER (3) NOT NULL,
DESCRIPTION VARCHAR2 (20),
PIC ORDIMAGE,
THUMB ORDIMAGE,
EMPLOYEE_NAME VARCHAR2 (50))
The 'browse' jsp displays the id, description and thumb image.
The 'edit' jsp allows the user to enter the description, employee_name and upload file details for the pic image.
I have 2 problems with the application.
1. How do I set the 'browse' jsp to display the thumb image as an anchor tag that points to the 'edit' jsp ?. I would also like to dynamically set the hint text for the thumb image to 'employee_name' from the database table.
2. In the 'edit' jsp I want to invoke the Intermedia processCopy method to automatically create the thumbnail image from the image file specified by the user. How do I accommodate this method into the default code ?
Thanks in advance
Chris

Chris,
Basically, you have to use the "manual" mode of the rendering instead of the "automatic" mode. The JDev Wizard
generated JSP page uses the "automatic" mode which is hard to customize. The characteristic of the "automatic"
mode is using the <AttributeIterate> tag to iterate through all attributes. You have to change the following JSP files
to achieve what you wanted.

Thumbnail images, bigger images and some text PROBLEM

Unclear title, with an unclear problem.
What I'm wanting to do is, when I click on a thumbnail image, I want the content in the DIV on the right to change accordingly to display the image and information relating to the thumbnail you have just clicked. I'm using Dreamweaver CS5 on MAC:
- I have a page split into 2 vertical columns. On the left I have 6 thumbnail images in their individual DIVs, wrapped all together in another DIV container
- on the right of the page I have assigned a large DIV to display a big image with a description underneath of what the project was etc...
I know you can attach a behaviour to the thumbnail to change the big image on the right, but I have a short paragraph of text below the big image too, and I don't particularly want to make the image and text one huge image. I want to keep the text, text.
How do I do it? Is this a simple thing? or is there a lot of coding to do this with JQuery or Javascript or something? Is there something to do with Data record sets involved?
Is there a way of doing it that when you click on the thumbnail that it can load the relevant image and text into the DIV on the right?
Sorry if it's not clearly explained, not sure how to do it, therefore not sure if I'm describing it properly.
As always, all help and advice very welcome.

Hi Murray,
Here is a screenshot of the page in question.
- On the left are the thumbBox DIVS, (shown here, "thumbBox1")
- On the right there is a main container, "galleryDisplay"
- Within "galleryDisplay" there is a DIV for the large image, "galleryDisplayImage", and another DIV to display a paragraph of information on the project, "galleryDisplayInfo".
Just to repeat, I want that when you click on the "thumbBox1", that the content of "galleryDisplayImage" and "galleryDisplayInfo" change in accordance to the thumbnail clicked.
Murray *ACP* wrote:
The easy way to do this is to have each click on the thumbnail change the display Property of a container (containing both the image and the caption) from "none" to "block". In the column on the right, just line up a series of divs, each containing the desired image+caption, and use DW's Chage Property behavior on a null link surrounding the thumbnail. For example, a thumbnail image:
<a href="#" onClick="MM_changeProp('image-caption1','','display','block','DIV'); return false"><img src="path_to_thumb.jpg" width="165" height="50"></a>
Each click on a thumb would also have to change the display Property of all other image-caption containers to "none".
I don't understand what I have to do with the relevant large image and text. You say to "line up a series of divs"... I don't understand. Where do I "store" the image and text combinations for each project? I can understand how an image can be loaded into the image div, but how and from where do I load in the html text with css applied into the info div?
Can I change the content of 2 separate divs from one click?
Sorry for not being overly clear, but I can't get my head round this.
Thanks for your help. I'm sure I'll get there in the end with your expertise.

JSP image button problem

Hello
I have a noob problem. I am trying to create an image button in my JSP page. I want to have an image as the background for the button with dynamic text on top of the image (in the foreground).
This is what I have so far.
<html:link href="javascript:submitLink('Monthly');"><html:img srcKey="button.buyPremium" altKey="motorInsuranceQuote.label.monthly" />Monthly Payment: <c:out value="${MotorInsuranceQuoteForm.monthlyPremium}" /></html:link>The problem with the above code is that it produces an image button that doesnt have the dynamic text on top of the image and centred. How can I go about doing this?
Thanks in advance for any help :-)

sorry, may be my lack of awareness or my curiosity to solve the issue forced me to ask such a wide (a bit foolish too,l i agree) question. sorry
but can u tell which all packages i hav to download from http://jakarta.apache.org/commons/fileupload/ for the proper working of this. bcoz i can see too many projects there in the download area. so that forbade me from doing some scratch works in that code. help me if u can

Thumbnail image problems continue...

Within a few minutes of opening FCPX the thumbnails disappear on the timeline and only one Thumbnail image at a time appears in the browser as I mouse on the clips. I have been able to fix this by trashing prefs and cache files but the problem never goes away.
I also notice that now when I quit it takes about two minutes as FCPX "cancels background tasks' - then it hangs and will not quit.
Anyone have an answer - there are other posts that refer to no thumbnails and I've tried most solutions with no complete or lasting success. Thanks.
I am on latest version FCPX and OS and running a new Mac Pro 6-core and 24Mb memory.

Thanks - I looked at this solution before with no luck.
But what I now see is that my render files were not being written - to force this I changed the location to the Library on my main editing drive and I think is now working.

How to I get high res thumbnail images?

Just discovered once I've imported images into my library Aperture 3.2.2 (running under 10.7.3) doesn't render high res thumbnail images (when the Browser Thumbnail Resize slider is set to the far right/maximum), even though my "Previews" preference settings are as follows:
"Use embedded JPEG from camera when possible" is unchecked
"Don't Limit" for Photo Preview is selected
Photo Preview quality set to 10
Deleting and regenerating thumbnails doesn't solve the issue. However, if I delete the photo from the referenced library, then reimport the image, the browser thumbnail image renders sharp. The low res thumbnail is at left; high res thumbnail (after re-import) is at right. Both thumbnails images are sharp when the Browser Thumbnail Resize slider is positioned in the middle. Photos render sharp in the Viewer, regardless.
Going back through my images, it seems Aperture stopped providing a sharp thumbnail image since around July 2010. Other than updating Aperture, my workflow or supported camera hasn't changed. Couldn't find a reference to this issue in the User Manual. Am I missing something a setting somewhere?
Thanks,
Eric

Its unclear if the command Generate Thumbnails actually does anything if the thumbs already exist and as there isn;t a Delete Thumbnails command like there is a Delete preview command there are only two ways to force a new thumb to be generated.
One is to import the image again and two is to delete the Thumbnail folder in the Aperture library. I don;t know for sure if this will fix you problem but as I said it is the only way to force the generation of the thumbs.
If you try this make sure you have a good working backup of the library. Nothing here will normally cause data loss but it is always a good idea before messing with the library.
Quit Aperture, Highlight the library in the Finder and right click, Select show package contents. One fo the folders you'll see is Thumbnails, delete it. Open Aperture.
Also be aware that the regeneration of the thumbs will take some time. Depending on the size of the library it could be an all day affair. Aperture is usable while this is going on but it will be slower.

Bad choice. Only one person involved in that thread knew what they were doing...and you copied from the wrong one.
Here is my procedure:Lose it. Custom download procedures are overcomplicated and now almost never required.
See the recommendation to use declarative BLOB support, as shown in the Thumbnail image problems.

Thumbnail images in the event browser

After about 20 minutes on FCPX the thumbnail images in the event browser randomaly disappear. If I move the scrubber bar over the blank thumbnail the image reappears but only for as long as I linger on the thumbnail. The audio track remains visible all the time. Changing the view or the scale doesn't help. It's difficult to find clips, as you can imagine. Anyone else having this problem?

Thanks Russ. After returning to original layout the problem subsided but returned after a longer time period (about two hours). I was just working (on a different project) and suddenly %90 of the thumbnails turned blue. I could still see the audio information but the pictures vanished. The picture returns when the scrubbing bar hovers over the thumbnail then disappears again when I take the bar away. This is incredibly frustrating. Could it be because I'm using a thunderboldt display off of my Mac Book Pro? Both are less than 1 year old and the Pro is (was) top of the line at the time. Blind as a bat.
