Problem webutil on server

Question

Hi all.
I have a problem with webutil on the server-side.
On my client-machine (operating system windows xp service pack2) everything it is ok. But when I run webutil on the server (operating system Linux), I have this message error:
"The webutil object group is not available in this form. Webutil cannot work.
Webutil error: oracle.forms.webutil.olefunctions bean not found. CLIENT_OLE2.create_obj will not work."
The thing that is strange is that local on my machine everything is ok. I have tried to cancel the library and the object group from the form and then to re-attach them, but the result is the same: local on my machine it's ok and on the server I have got the message above.
Is there anyone that can help me???
Thanks, Fabrizio

Dear Fabrizo ;
I am so sorry i did not work on Linux plafrom befor,
but i think it has the same configuraion as windows.so if you check webutil configuration again and again i think it could work.
and this is webutil configuration

2- ....................... HOW TO CONFIGURE AND DEPLOY WEBUTIL .
3- ....................... HOWT O ATTACH IT IN UR FORM .
1 - The Principles of the WebUtil Design :-
The aim of WebUtil is to provide a utility that any Forms developer can use to carry
out complex tasks on the client browser computer by simply coding in PL/SQL.
Although WebUtil itself uses Java extensively, there is no need for the developer to
have any understanding of Java. Everything the developer needs to do is exposed
through a standard PL/SQL library webutil.pll.
All of the components that are needed to support WebUtil are likewise exposed
through a simple object group.
For an Oracle Forms application to take advantage of WebUtil, you only need to attach
the WebUtil library and subclass the Object Group. No setup or configuration in code
is required as WebUtil is self-configuring and where necessary, self-installing.
Some features of WebUtil, such as client side OLE integration, require code to be
installed onto each client computer. One of the key features of WebUtil is its ability to
"self-install" in these cases. There is no need for an administrator to configure each and
every computer because WebUtil detects which client-side pieces are missing and
automatically installs them.
Another aim of WebUtil is to simplify porting of client server integration code to work
on the client browser computer. To achieve this, WebUtil contains PL/SQL APIs mimic
the behavior of the equivalent native Forms functions.
An example of this is the Forms TEXT_IO package. This package provides the
developer with facilities to read and write text files on the application server. WebUtil
provides an alternative implementation, CLIENT_TEXT_IO, which is identical to
TEXT_IO except that calls are implemented on the client browser computer rather than
on the middle tier. Migrating existing code to operate on the client can be achieved
using a simple search and replace operation in the PL/SQL code to changes references
to point at the alternative "CLIENT" implementations provided by WebUtil.
The final goal of WebUtil design is to add value to Oracle Forms as a product. WebUtil
adds capabilities to Forms which have simply not existed before in either web or client
server deployments.

2-4 : From folder "webutil_106" Copy file "frmwebutil.jar" in path "DeveloperHome\forms\java"
-- note this step in release 3 is done .
2-5 : Edit file"D:\DevSuiteHome_1\j2ee\DevSuite\application-deployments\forms\formsweb\orion-web.xml"
by notepad and add this code
<virtual-directory virtual-path="/webutil" real-path="D:\oracle\product\10.1.0\Developerhome\forms\webutil" />
-- note this step in release 3 is done .
2-6 : Edit file "Developerhome\forms\server\server\formsweb.cfg " and add this code
archive_jini=frmall_jinit.jar,frmwebutil.jar,jacob.jar
archive=frmall.jar
2-7 : at the end of this file add also

--not in releas 3 u will find this block of code replace it by this code
2-8 : edit file "developerhome\forms\server\default.env" add this code
FORMS_PATH=D:\DevSuiteHome_1\forms;D:\DevSuiteHome_1\forms\webutil
WEBUTIL_CONFIG=D:\DevSuiteHome_1\forms\server\webutil.cfg
2-9 : at line class_path add this code in addition of it's code and remember to modify ur home path
;D:\oracle\product\10.1.0\Developer\forms90\java\jacob.jar;D:\oracle\product\10.1.0\Developer\jdk\jre\lib\rt.jar;D:\oracle\product\10.1.0\Developer\forms90\java\frmall.jar;D:\oracle\product\10.1.0\Developer\forms90\java\frmwebutil.jar
2-10 : Replace all code in line "path" by again remember to modify the developerhome
PATH=d:\oracle\product\10.1.0\Developer\jdk\bin;d:\oracle\product\10.1.0\Developer\jdk\jre\bin\classic;d:\oracle\product\10.1.0\Developer\jdk\jre\bin; d:\oracle\product\10.1.0\Developer\jdk\jre\bin\client;d:\oracle\product\10.1.0\Developer\jlib;d:\oracle\product\10.1.0\Developer\bin;d:\oracle\product\10.1.0\Developer\jre\1.4.2\bin\client;d:\oracle\product\10.1.0\Developer\jre\1.4.2\bin;

2-11 : Edit file "devloperhome\forms\server\webutil.cfg" and add these two lines at the end of it
transfer.database.enabled=TRUE
transfer.appsrv.enabled=TRUE
-- very important note the two lines
transfer.appsrv.read.1=C:\ -- Only files in this directory can be downloaded from AS
transfer.appsrv.write.1=C:\ -- Only files in this directory can be uploaded to AS
2-12 : Open msdos(or shell on linux) and run these batches :be carefull to run tis batch put it first in the JDK\bin home:
sign_webutil.bat DeveloperHome\forms\java\frmwebutil.jar
sign_webutil.bat DeveloperHome\forms\java\jacob.jar
2-13 : And now create user may be "webutilowner" or as u like to name it
create user webutilowner identified by webutilowner;
conn webutilowner/webutilowner
from folder "webutil_106" u will find this script "create_webutil_db.sql" run it on this user
grant execute on WEBUTIL_DB to public;

3-1 : From "webutil_106" copy this liberary "webutil.pll" and "webutil.olb" in ur ofismain
3-2 : Open ur module and at pl/sql liberraries open file then open "webutil.pll" from ur ofismain
3-3 : Compile this liberrary.
4-3 : Then attatch this liberrary to ur module .
4-5 : At object liberraries open the "webutil.olb" from ur ofis main
4-6 : THEN right click and choose object liberary
4-7 : You will have a window restore it down and drag "webutil" from it to ur object group at ur module.
4-8 : You wil have a window asking for copy,subclass or cancel choose copy, but for more dynamic coding u have to choose subclass
4-9 : You will have a block called webutil move it to be last block.
4-10 : then see some examples to use it we have example form called module2.fmb
