It is possible don't usa JACOB:JAR ?'

I have read taht it is possible to don't use JACOB:JAR files.
Because i don't install webutil 1.0.6 on AS 10.1.2 (a lot of big problem, don't start applt with an error rtc etc ) i ask if it is possibile to don't use JACOB.JAR and this case how it is possible :
1) what kind of modify i must do in the files
2) must i signfrmwebuitl.jar also ??
Than'k for replay.

1) You can download pictures from web. The only protocol supported by all devices is 'http'. Also, you may display images using png format only.
(http://wireless.java.sun.com/midp/samples/#nw)
2)To issue a app to run on your server, basically you have to make another app that is listening on the server, and when it gets a 'command' from your device, it will spawn a new process and run the desired app.
To do this, either use existing web server and create a php/jsp/asp script, or create a application by yourself based on a server socket listening on an arbitrary port, and having abilities to parse the http headers (that will come along with your device's request).

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

Jacob.jar Help/Webutil Error-Urgent Help Needed

We are not using any OLE object in forms.But after implementation on WEBUTIL the browser starts giving below error:

Can anyone help ?
Is jacob.jar is required to download even if we don't need it.
Thanks

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

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

Webutil - jacob.jar

Webutil seems dont work without jacob.jar which is not included in webutil_102.zip !
What is the reason ?

Hi Bernhard,
I wanted to use Jacob.jar for generating word documents using JSP. My word document should be generated dynamically using JSP .
It should be possible to create tables,headers,footers,draw lines in the word document.
Can i use jacob.jar.Where can i download ?
if this does not support all the above features,
is there any other opensource library which can be used to solve the same above said purpose.....
pls reply soon...
Thanks in advance.....

I have seen sites to sign the jar files, but is it possible to overcome this error without signing. Since this error is taking 10-20 secs more to load the form.
Please help.

HI,
You need to sign both frmwebutil.jar and jacob.jar first the clear JAR cache ion end-user computer,so that new signed JAR files are downloaded to end-user machines..

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:

Frmall.jar, jacob.jar,... determine certificate with which they were signed

hi,
oracle forms provides signed jar-files (frmall.jar, jacob.jar,...).
is there a way to determine the certificate with which the particular jar-file was signed?
regards,
matthias

hi
you will find a batch file inside in the webutil folder.
mkcrt something like this.
u can make certificate by using that batch file in command prompt.

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

Is it possible to verify a signed jar-file from a program?

Is it possible to verify a signed jar-file from a program
(using some API) likewise jarsigner does?

Is it possible to verify a signed jar-file from a
program
(using some API) likewise jarsigner does?Hi,
You would have to open the jarfile, read each jar entry and for each of them do a getCertificates() and then in turn verify each certificate with the public key of the enclosed certificates in the jar file.
An easier solution would be to use the verify flag of the JarFile or JarInputStream.
Hope it helps..
Cheers,
Vijay

Perhaps you are using old WLST code (used for OSB 10g), with OSB 11g.
The ALSBConfigurationMBean (com.bea.wli.sb.management.configuration.ALSBConfigurationMBean) Interface in the com.bea.wli.sb.management.configuration package in the Oracle Fusion Middleware Java API Reference for Oracle Service Bus includes example code illustrating how to import and export Oracle Service Bus 11g configurations, how to change environment values, how to query resources, and so on.

Is it possible to compile/convert class/jars to DLL?

Hi all,
Is it possible to compile/convert class/jars to DLL so that my VB program can use it? If yes, how do i do it?
thanks for your time.

No it is not (afaik). But as far as the VB stuff goes, somebody who posted here earlier mentioned passing data to VB functions. Can't remember which post it was.
One thing you can do is use sockets to send data between your Java code and VB application using sockets. Sockets are easy to use in Java, and in VB you just need to use the stuff in ws2_32.dll. You can find VB modules for sockets all over the place.

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...

It is possible don't usa JACOB:JAR ?'
