Jacob.jar Help/Webutil Error

We are not using any OLE object in forms.But after implementation on WEBUTIL the browser starts giving below error:
java.lang.NoClassDefFoundError:com/jacob/com/ComFailException
Can anyone help ?
Is jacob.jar is required to download even if we don't need it.
Thanks
Mandeep Singh

Yes, it seems from Jacob zip file jacob.jar is also needed to be extracted into the web util (lib) directory.
Please review Oracle Metaink: com/jacob/com/ComFailException When Deploying Form With Webutil: Doc ID: Note:247007.1
Hope it would be helpful.

Thanks for quick response.
But my question is do we need to config jacob lib even we dn't need it.I am asking this because with this release of WEBUTIL,jacob is a seperate lic. product and its not a part of WEBUTIL pack.
Thanks

Jacob.jar and Webutil.jar singing problem(URGENT)

I read the instructions 'Configuring the webutil' and I found that there is not a reference in the file 'signer.properties' which is referenced in the on-line help of Forms Developer (step 4).
The problem is that when i try to sign the 2 jar files 'frmwebutil , jacob'
using this command
E:\oracle\ora92\forms90\WEBUTIL>SIGN_WEBUTIL.BAT e:\oracle\ora92\forms90\java\jacob.jar
after this command a essage appears:
Genrating self signing certificate for key=webutil2...
Keytool error :java .lang.execption:key pair not genrated ,alias <webutil2> already exists
there were wanings or error while genrating a self singing certifciate . please review them.
backing up e:\oracle\ora92\forms90\java\jacob.jar as e:\oracle\ora92\forms90\java\jacob.jar.old
1 file(s) copied..
singing e:\oracle\ora92\forms90\java\jacob.jar using key=webutil12...
'jarsigner' is not recognized as an internal or external command.
Is there a chance that the cause of this problem is that there is not the file 'signer.properties'?
What can I do ?
AND WHAT THE NEXT STEP AFTER THIS....
INDU

Update the sign_webutil.bat to add the full path before the jarsigner line
Here is the files I use:
makecert.bat:
for /F "eol=# tokens=1,2* delims==" %%i in (signer.properties) do set %%i=%%j
"%JDK_HOME%\bin\keytool" -genkey -dname "cn=%DN_CN%, ou=%DN_OU%, o=%DN_O%, c=%DN_C%" -alias %JAR_KEY% -keypass %JAR_KEY_PASSWORD% -keystore "%JINIT_HOME%\lib\security\keystore" -storepass jinitiator -validity 360
@echo Certificate created...
sign.bat:

Jacob.dll and jacob.jar have no size.

Hi. I downloaded jacobBin_17.zip to sign webutil.jar and jacob.jar. When i extract jacob.dll and jacob.jar to Webutil/Lib directory, I see the they both have 0 KB in size. The jacobBin_17.zip I downloaded is 175 KB in size. Is ths the correct size?, and if so, what's wrong?

the size of jacobBin_17.zip is correct (175KB) and When i extract jacob.dll and jacob.jar to Webutil/Lib directory the sizes are jacob.dll(92.0 KB (94,208 bytes)) and jacob.jar (16.1 KB (16,554 bytes)).
Try to unzipped the zip file again. it's maybe a windows error....it's strange
good luck

Webutil.jar and jacob.jar in same archive ?

Hi,
When a user connects for the first time to a webutil configured Forms application, 2 popups show up and ask to accept the X509 certificate (because webutil.jar and jacob.jar are signed).
Our customer wants to know if it's possible to show only one popup (to reduce enduser hassle).
How can we do it ?
Is it possible to package webutil and jacob in the same single archive, sign this archive and so have only one popup ?? Any other ideas ?
Regards

It's not impossible to find a solution, but then you are miles away from any support from the oracle hotline.
Don't do that
Gerd
PS: Are your users inhouse. Is it possible, that you deploy the jar's via a Software Management System? That may help in this case

Maybe you could try to change the values in your sign_webutil.bat file:
REM Give your alias key here.
REM
SET JAR_KEY=webutil3
REM
REM Key Password for the given key to be used for signing.
REM
SET JAR_KEY_PASSWORD=webutil3

Did you change the variables in your sign_webutil.bat file?
Because this batch file creates you a new keystore with information about your company etc.
Maybe you should take a look at the batch file.
The Java Error in the console indicates that the jar file didn't get signed right btw...

Help On Error WUC-015 of WebUtil

Hi,
We try to convert form6I to form9I and use the WebUtil but we are having trouble of how to configure the WebUtil. We all follow the "WebUtil Familiarization Manual" to configure the WebUtil but none of us got it works. One of my co-worker told by the Metalink people she needs to sign the jar file before she can use the WebUtil but that is no mention at all on the above manual. The Metalink people refused to help me!!
Can you show me where can I get documents with more details on
1, What steps have to go through in order to use the WebUtil.
2, How to set up the Alias and Virtual directory in the configure files (more detail examples).

Please read the documentation that comes with webutil. There is a README file which says:
"Signing the jars
The webutil.jar supplied in the zip file is already signed one. In case one would like to resign it using the utility supplied, it can be done using the following steps.
Signing the jar is a one-time operation until we make any further change to the jar file.
There are one or two steps to get webutil configured but we have had thousands of people downloading and using webutil, you just need to make sure yuo follow the instructions closely.
Once you have signed the JAR files please try again (also check out the webutil FAQ on otn) and let us know if you have any problems then.
I hope that helps

Perhaps you are using old WLST code (used for OSB 10g), with OSB 11g.

Hi,

Today I tried to test again the form, and I got an error when the form is opening, I review the log and I find "unable to communicate with runtime process.".....
I didn't change any configuration... what I'm doing wrong..... It just work great yesterday!!!!
I tried signing again the jacob.jar and frmwebutil.jar files..... However I still have the error.......

WebUtil Error Bean Not Found

Dear All,
i am facing a problem of running webutil functions. I have compiled my webutil.pll and then attach to my form and then i copy the webtuil.olb objects into my
form and i created one button on my form to show the calculator the code is as follows
Note: i have webutil.cfg in my classpath of default.env file and i signed both webtuil.jar and jacob.jar successfully but still i am facing error.
e.g;
when-button-press
webutil_host.host('calc.exe');
error: oracle.forms.webutil.host HOST bean not found.
WEBUTIL_HOST.execute will not work.
Thanks.
Immediate help will be appreciated....

Hi,
Have you entered the webutil values in the formsweb.cfg file?
e.g. WebUtilConfig=<somewhere>\WebUtil\server\webutil.cfg
WebUtilArchive=frmwebutil.jar,jacob.jar
WebUtilErrorMode=Alert
WebUtilConfig=<somewhere>\WebUtil\server\webutil.cfg
baseHTMLjinitiator=<somewhere>\WebUtil\server\webutiljini.htm
baseHTMLjpi=<somewhere>\WebUtil\server\webutiljpi.htm
baseHTML=<somewhere>\WebUtil\server\webutilbase.htm
Hopefully this may help you.

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).

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?

How to get up and running with WebUtil 1.06 included with Oracle Developer Suite 10.1.2.0.2 on a win32 platform
Solution
Assuming a fresh "Complete" install of Oracle Developer Suite 10.1.2.0.2,
here are steps to get a small test form running, using WebUtil 1.06.
Note: OraHome is used as an alias for your real oDS ORACLE_HOME.
Feel free to copy this note to a text editor, and do a global find/replace on
OraHome with your actual value (no trailing slash). Then it is easy to
copy/paste actual commands to be executed from the note copy.
1) Download http://prdownloads.sourceforge.net/jacob-project/jacob_18.zip
and extract to a temporary staging area. Do not attempt to use 1.7 or 1.9.
2) Copy or move jacob.jar and jacob.dll
JacobStage is the folder where you extracted Jacob, and will end in ...\jacob_18
cd JacobStage
copy jacob.jar OraHome\forms\java\.
copy jacob.dll OraHome\forms\webutil\.
The Jacob staging area is no longer needed, and may be deleted.
3) Sign frmwebutil.jar and jacob.jar
Open a DOS command prompt.
Add OraHome\jdk\bin to the PATH:
set PATH=OraHome\jdk\bin;%PATH%
Sign the files, and check the output for success:
OraHome\forms\webutil\sign_webutil OraHome\forms\java\frmwebutil.jar
OraHome\forms\webutil\sign_webutil OraHome\forms\java\jacob.jar
4) If you already have a schema in your RDBMS which contains the WebUtil stored code,
you may skip this step. Otherwise,
Create a schema to hold the WebUtil stored code, and privileges needed to
connect and create a stored package. Schema name "WEBUTIL" is recommended
for no reason other than consistency over the user base.
Open OraHome\forms\create_webutil_db.sql in a text editor, and delete or comment
out the EXIT statement, to be able to see whether the objects were created witout
errors.
Start SQL*Plus as SYSTEM, and issue:
CREATE USER webutil IDENTIFIED BY password
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp;
GRANT CONNECT, CREATE PROCEDURE, CREATE PUBLIC SYNONYM TO webutil;
CONNECT webutil/password@connectstring
@OraHome\forms\create_webutil_db.sql
-- Inspect SQL*Plus output for errors, and then
CREATE PUBLIC SYNONYM webutil_db FOR webutil.webutil_db;
Reconnect as SYSTEM, and issue:
grant execute on webutil_db to public;
5) Modify OraHome\forms\server\default.env, and append OraHome\jdk\jre\lib\rt.jar
to the CLASSPATH entry.
6) Start the OC4J instance
7) Start Forms Builder and connect to a schema in the RDBMS used in step (4).
Open webutil.pll, do a "Compile ALL" (shift-Control-K), and generate to PLX (Control-T).
It is important to generate the PLX, to avoid the FRM-40039 discussed in
Note 303682.1
If the PLX is not generated, the Webutil.pll library would have to be attached with
full path information to all forms wishing to use WebUtil. This is NOT recommended.
8) Create a new FMB.
Open webutil.olb, and Subclass (not Copy) the Webutil object to the form.
There is no need to Subclass the WebutilConfig object.
Attach the Webutil.pll Library, and remove the path.
Add an ON-LOGON trigger with the code
NULL;
to avoid having to connect to an RDBMS (optional).
Create a new button on a new canvas, with the code
show_webutil_information (TRUE);
in a WHEN-BUTTON-PRESSED trigger.
Compile the FMB to FMX, after doing a Compile-All (Shift-Control-K).
9) Under Edit->Preferences->Runtime in Forms Builder, click on "Reset to Default" if
the "Application Server URL" is empty.
Then append "?config=webutil" at the end, so you end up with a URL of the form
http://server:port/forms/frmservlet?config=webutil
10) Run your form.If its Correct/Helpful please mark it thanks.
