Pb Webutil106 client_image.read_image_file

Bonjour,
j'ai un pb avec une webutil 106 sur un Application Server 10.1.2.0.2
Certaines fonctions plantent
oracle.forms.net.ConnectionException: Abandon de la session Forms <839> : communication avec le processus runtime impossible.

at oracle.forms.net.ConnectionException.createConnectionException(Unknown Source)

at oracle.forms.net.HTTPNStream.getResponse(Unknown Source)

at oracle.forms.net.HTTPNStream.doFlush(Unknown Source)

at oracle.forms.net.HTTPNStream.flush(Unknown Source)

at java.io.DataOutputStream.flush(Unknown Source)

at oracle.forms.net.StreamMessageWriter.run(Unknown Source)

Pour tester, j'utilise la forme de demo WU_TEST_106 et les pbs que je rencontre sont sur :
CLIENT_IMAGE.READ_IMAGE_FILE
la plupart des autres fonctions de la Webutil fonctionnent (j'ai juste constaté un pb sur SHOWBEANS(FALSE) qui ne rend pas la main)

J'ai une autre plate-forme quasiment analogue (serveur RedHat4, même version de webutil et d'AS, sinon que c'est une install Portal) et là ça marche correctement.
Je teste avec le meme poste client et la même base.

J'ai épluché Internet où je retrouve des descriptions de pbs analogues sans trouver de réelle solution.

Merci pour toute idée.

FYI

Subject: READ_IMAGE_FILE Fails With FRM-47100 For JPG's Stored In Exif Type Format.
Doc ID: Note:402773.1 Type: PROBLEM

Applies to:
Oracle Forms - Version: 6.0.8 to 10.1.2
This problem can occur on any platform.
Symptoms
On trying to insert or upload an image with the forms built-in READ_IMAGE_FILE you get the following FRM error.

FRM-47100 : Cannot Read Image File

The same occurs when using Webutil function CLIENT_IMAGE.READ_IMAGE_FILE. However, other image file have no problem being read into forms.

Changes
It seems most of the jpg files that cannot be uploaded are created from digital cameras.
Cause
The failing image is in an Exif (Exchangeable image file format) format. Forms cannot read jpg's which have this format.
From the following bug,

Bug 5135787 - FRM-92101 ERROR WHEN OPENING A PICTURES IN AN ITEM TYPE ''IMAGE'' IN FORMS

development have commented the following.

"Please note: Progessive JPEG" format not supported in Forms. Only "BaseLine JPEG" format is supported (JFIF in the header). Most of the Image format which has Exif info ( Digital Cameras' additional info) not properly recognised by forms.

Digital camera, add the Exif type information such as into a jpg file.
Solution

Since forms cannot read Exif format you will need to remove the exif information from the jpg file for forms to work. This can be done using any 3rd party tools that has this functionality. IrfanView (http://www.irfanview.com/) is one such tool and can be downloaded as freeware.

Of course, removing Exif information for one file is ok, but if hundred's of jpg files need to be converted, then this is very time consuming. InfraView has functionality which will convert all images in a certain directory in batch. See InfraView online help for more information.

The following enhancement request has been logged with development.

Bug 1197043 - ENH PROVIDE SUPPORT FOR READ_IMAGE_FILE READING IMAGE

With EXTENSION .EXIF
( Not public visible )

At this moment it is not planed to apply the Enhancement request.

Merci pour cette info mais le format d'image n'est pas en cause puisque sur mon autre plateforme, je n'ai aucun pb avec ces fonctions de la WebUtil
