Availability of Multiple EBS Forms Sessions with Java Web Start
We are pleased to announce that our solution for using Java Web Start with Oracle E-Business Suite now allows users to open multiple Oracle Forms sessions simultaneously. This extended functionality is a result of extensive collaboration between the EBS, Forms, and Java development teams.
Our initial certification in April 2017 for using Java Web Start with Oracle E-Business Suite employed a single instance of Oracle Forms on a user's desktop. Subsequent requests to open any Oracle Forms based module were always routed to the already running Oracle Forms application. As such, it was not possible to open multiple instances of Oracle Forms in EBS side-by-side.
With this update, you can now perform important business tasks more productively using Java Web Start, in a similar way to what was previously possible with the JRE Plug-in.
My Oracle Support Note 2188898.1, Using Java Web Start with Oracle E-Business Suite, explains how you can migrate your Oracle E-Business Suite 12.2 or 12.1 environments to use Java Web Start. If you have already performed such a migration, the same note lists requirements for using this feature.
Additional Improvements
When running multiple Oracle Forms sessions with Java Web Start, you are now also able to:
- Launch multiple Oracle Forms based modules from a single browser session. To open multiple Oracle Forms sessions, you no longer need to start multiple browser sessions as was required when using the Java Plug-in. With Java Web Start, you specify a preference on the General Preferences page to open multiple Oracle Forms sessions.
- Log in only once when working with multiple Oracle Forms sessions. Since multiple browser sessions are no longer needed, you do not need to log in to Oracle E-Business Suite multiple times. When using the Java Plug-in, users had to launch multiple browser sessions and consequently sign in to EBS multiple times.
- Use additional browsers. Java Web Start can be used with browsers that do not support the Java Plug-in, and so is certified with more browsers. For a list of browsers certified for use with Oracle E-Business Suite, refer to Recommended Browsers for Oracle E-Business Suite Release 12 (MOS Note 389422.1).

After seeing your previous blog dated 01-Mar-2019 regarding recommendation to migrate to JWS, we did migration as per steps mentioned in Note 2188898.1 but after that we are facing serious issue w.r.t Multiple EBS forms and exactly the same as described in Note 2379964.1. We have also raised SR with Oracle support and working since last 3 days but in vain. Issue is on IE 11.
I will appreciate any help in this regard.
Thanks for bringing this issue to my attention. We think your comment is relevant for SR 3-19558682531. If this is the case, our technical and support experts are reviewing this. Since the issue does not occur in Chrome, Firefox and Edge, we think it is related to some IE settings. We are investigating this and will respond via the SR. It would be best to keep working through the SR to reach a proper resolution for your issue.
Thank you for taking the time to share your feedback. We are glad to hear this.
Thank you very much for sharing your experience.
I wonder whether there is an workaround for avoiding the annoying default behaviour of MS Edge browser & Java Web Start any time a user needs to open a Form:
"...
5.A new browser tab opens and the downloaded frmservlet.jnlp is saved in the Downloads folder
6.Click Open to execute the file frmservlet.jnlp..."
This seems quite an obstacle for implementing the Java Web Start in our organisation.
Thanks in advance
Kind regards
The current behavior is inherent to Microsoft Edge, and its limited capability of automatically executing downloaded files such as the JNLP file. If this proves to be major obstacle for your organization, then I would recommend you to looking at the other supported Web browsers like Mozilla Firefox ESR, which is able to launch the JNLP file without any user interaction.
Kind regards,
