Re: Displaying Images Stored in DB on Openshift

2014-07-14 Thread Martin Grigorov 
Hi,

Is it possible to attach remote debugger to OpenShift and see what happens ?
If it is not possible then add some logging statements and see what is
returned from the DB (byte[]) and whether Wicket creates a proper
BufferedImage, whether it is written down in the resource's WriteCallback,
etc.

 Hi Guys

 After some more trial and error and research I have got the image to store
 properly and write back out a valid image using BufferedImage and ImageIO.
 However I am still not able to display the image. I just get the picture
 symbol and he link looks like img alt=
 src=./account?12-IResourceListener-profileImage.

 The code used is as follows:

 BufferedDynamicImageResource bufferedDynamicImageResource = new
 BufferedDynamicImageResource(jpeg);
 bufferedDynamicImageResource.setImage(image);
 Image proImage = new Image(profileImage, bufferedDynamicImageResource);
 add(proImage);

 Where image is a BufferedImage. The file command outputs the following.

 I am running Wildfly 8.1.0. Any suggestions .

 Thanks

 David

  Hi All
 
  I am developing and application that is running on openshift. The
  application is still in heavy development, using wicket 6.14 at the
 moment.
  I am running Wildlfy 8.1.0 and testing locally.
 
  The problem I am facing is simply that the images that I am storing are
  not being displayed on Openshift but work fine locally. I am retrieving
 the
  image as a byte[] from the database and then displaying the Image.
 
  I have tried using a simple ByteArray Resource like the following:
 
  ThumbnailImageResource imageResource = new ThumbnailImageResource(new
  ByteArrayResource(image/jpeg, userAccount.getProfileimage().getFile()),
  150);
  Image profileImage = new Image(profileImage,
 imageResource);
  add(profileImage);
 
  However on Openshift the image does not display. There is no error logged
  just no image and the resource link does not seem to work either.
 
  Any thoughts would be most helpful.
 
  Thanks

Hi Martin

Thanks for your reply. Attaching a debugger is really easy with OpenShift
and is what I did. I was able to see that storing the file was in fact
producing the wrong set of image bytes, hibernate postgresql issue. Once
fixed I was able to check the file and image properly. All seemed to work
so randomly I cleared the browser cache and all works well. Is there a way
to stop the browser caching the images if I wanted to?

Thanks

David

Lock at NonCachingImage: it generates a random noise so that images are
always reloaded. Also on FF you can play with about:config to disable
caching.
