Since we originally announced availability of Java Web Start for Oracle E-Business Suite 12.2 and 12.1 in April 2017 some developments have taken place. The bottom line is that we highly recommend all our Oracle E-Business Suite customers to migrate your Oracle E-Business Suite client tier to use Java Web Start (JWS) without delay.
Some of the recent expected developments that increase the importance of moving to Java Web Start include:
- Java Plug-in Extended Support ends in March 2019
- Firefox 52 Extended Support Release (the last Firefox release to support the Netscape Plugin API (NPAPI) required by Java Plug-in) ended in September 2018
- Safari 12 and higher does not include support for NPAPI (announced in September 2018)
In addition to this, Oracle E-Business Suite has released the following:
- Java Web Start with Oracle E-Business Suite 12.2 and 12.1
- Java Web Start with Firefox on macOS
- Multiple Oracle Forms sessions with Java Web Start
Begin Your Migration to Java Web Start
My Oracle Support Note 2188898.1, Using Java Web Start with Oracle E-Business Suite contains details about how you can migrate an existing Oracle E-Business Suite 12.2 or 12.1 environment to use Java Web Start. This includes recently added support for multiple Oracle Forms sessions.

While you transition to Java Web Start, you may ask what happens if you encounter issues using the Java Plug-in with EBS? For the answer to this and many other important Java-related questions, refer to My Oracle Support Note 2510500.1, FAQ: Essentials of Java Usage in Oracle E-Business Suite.
