How to create button with image in Oracle Forms 11g

Su.gi

Hi All,

  I am developing an application using Oracle Forms 11g.

In Formsweb.cfg imagebase parameter is codebase.

I am using Button images from my icons.jar.

My requirement is

I need to create button with image without using any jar files.

How to do this?

Thanks,

If the image is not in a jar, where would you like to store it?  Storing it on a remote server is not recommended as this will degrade application performance.  Consider that each time the button is rendered, it will have to return to the server and ask for the image again.

The simple answer to your question is that if you want to do what I mentioned, even though not recommended, you simply replace the Image file name with the URL to the image.  For example:

https://community.oracle.com/people/Su.gi/avatar/46.png

You can also use a relative path.  So if the image is located on the same server with Forms but in the web server's images directory, you could enter a value like this:

/images/myImage.jpg

To troubleshoot problems trying to understand the properly URL, use the Java Console in trace mode.  It will show you exactly where the request is going.  You should be able to see what is wrong with the request and correct it as needed.

Thanks for your reply Michael.

      I would like to store my images in my Application Server like (E:\app\Middleware\Oracle_FRHome1\forms\Icons).

All the client system should access the images from my Application server and those systems doesn't need internet access.

Is there any possible way to store images in client system and access it in my application (as like java)?

Thanks in advance,

Su.gi

Su.gi,

Please can you share your reason for NOT wanting them in a JAR?

JAR is really the optimal method to use images. Again, read the first line of Michael's response.

Using a JAR file will see the JAR downloaded automatically to each client, and the images will then be accessed from the JAR file on client storage.

Jar File Signing  can be reason probably, at least for me

Self Signing need to apply each client .

Thanks for your reply Roelof.

   If I used self signed Jar means, It has been blocked by updated Java versions.

Thanks for your reply Celal.

I am using self signed jars only for images.

But now a days Java updates blocking my self signed Jars.

Then is there any possible solutions for loading image in button without jars.

Thanks,

The best price is 95$ per year for a code signing certificate  from a Trusted Certificate Authority

and you does not have any trouble ( and incl. the -tsa 'timestamps' ... ) !

I have verified this.

Thanks for your reply fxmatz.

I know the cost for trusted certificates.

My requirement is how to load image icon on button without jar files.

Is it possible.

Thanks,

As I mentioned previously, not using a jar file is possible, but is strongly discouraged for a variety of reasons.  It should also be noted that the requirement of signing jar files was introduced in order to improve the security around Java applets.  Trying to avoid or work-around any security features is never a good idea and should certainly not be considered in a professional environment.  Electing to not use signed jar files may put your environment at risk.  For educational or local testing purposes, the use of self-signing is sufficient and is easy to implement given that such environments would generally be individual users only.

If you refer back to my original response, I explain how to do what you've asked.

Thanks for  your reply Michael.

I am testing my application in local. I am not having webserver. I just having the images in my local system only. And also i dont have an internet connection for that system.

Is this possible?

Thanks,
