Easy implementation JWS for EBS 12.X

1. Java Web Start + Oracle EBS

2. What : Java web start
Why : We need with EBS
How : We can implement

3. Java Web Start software is installed
as part of the Java Runtime
Environment (JRE) software.
Java Web Start provides a browser-
independent architecture for
deploying Java 2 technology-based
applications to the client desktop.
Java Web Start applications can be launched independently of a browser since they do
not rely on a browser plug-in, it provides a migration path from Java applets.
Until Now:
E-Business Suite's Java-based content required a browser
that supports Netscape Plug-in Application Programming
Interface (NPAPI) plug-ins, which is used by the Java
Plug-in.
We can only use browser which supports Netscape Plug-
in Application Programming Interface

4. The Oracle E-Business Suite migration to Java
Web Start is Primarily driven by
Modern web browsers ending support for the Netscape
Plug-in Application Programming Interface (NPAPI).
Oracle Plans to depreciate the Java Plug-in for web
browsers starting with release Java SE 9
Java Web Start applications can be launched
independently of a browser

6. Enabling Java Web Start
Option 1: Set Java Web Start as the default for all application users
Option 2: Set Java Plug-in as the default and Java Web Start for specific application users
Option 3: Set Java Web Start as the default and Java Plug-in for specific application users

7. User Experience When Migrating to Java Web Start
Java Web Start, Java applications are still launched from the browser, but now
all Java applets in Oracle E-Business Suite will run outside of the web browser. It
opens in a new and separate Java window, instead of displaying the Java applet
directly within the web browser using the Java Plug-in.
Only one instance per Java applet can be running on the client PC. Multiple
instances of a specific Java applet cannot be launched, even when launched
from different sessions or browsers.
Client (desktop) tier: The time taken to open the Forms application in Oracle E-
Business Suite with Java Web Start is comparable to that seen with the Java
Plug-in. There is no significant variation observed in CPU utilization and memory
consumption.
Application tier: There is no significant variation observed in CPU utilization and
memory consumption for the oacore and forms services
Database tier: A slight increase in number of database connections is seen with
Java Web Start on Oracle E-Business Suite Release 12.1.3. here was no such
difference observed with 12.2.
