WUT-125 Webutil Error happens occasionally....

Question

Hello,
We are currently running OAS 10g (10.1.2) ti deliver a web-based Forms application to our users (some are onsite and some off-site).
We use the WEBUTIL file transfer function CLIENT_TO_AS_WITH_PROGRESS to allow the users to upload their work (they are illustrators) tot he server, to be added to their image library.
Occasionally, and almost always offsite and therefore outside our firewall, we get the following error (please note I have replaced the URL value for anonymity):
Loading http://URL/forms/java/frmwebutil.jar from JAR cache
Loading http://URL/forms/java/frmall_jinit.jar from JAR cache

Forms Applet version is : 10.1.2.3

As said, it is a sporadic problem but then seems to persist for certain files.
I should also note that the directory /data is actually a linked folder on the UNIX box pointing to an area on a Windows file server.
This process works more often than not but around 5% are getting this error and thus stopping certain users being able to complete their work...
We've tried to trap this error via the WEBUTIL error log but the errors are not being logged there.
Very odd and head scratching time, thus... help?
Cheers
Dan

hi
u have to sign jars something like this.
o C:\cd <Developer Home>\jdk\bin
o C:\<Developer Home>\jdk\bin>
<Developer Home>\forms90\webutil\sign_webutil.bat
<Developer Home>\forms90\java\frmwebutil.jarand also u have to modify Default.env. something like this.
In a new line under (FORMS90_PATH=) add this line:
o WEBUTIL_CONFIG=<Developer Home>\forms90\server\webutil.cfg
when i signed the jars so i got the result something like this in java folder.
jacob.jar.old
hope it helps u.
