Java Web Start provides a browser-independent way to launch Java applications, allowing Oracle EBS apps to be launched without browser plugins. Migrating EBS to JWS requires installing JRE and EBS patches, setting the launch method to JWS, and results in apps launching in a separate window instead of the browser. Performance is similar to the Java plugin with some increase in database connections for EBS 12.1.
Java web start Quick Reference
- 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 Java Plug-In Java Web Start Microsoft Internet Explorer Yes Yes Microsoft Edge Yes Firefox Rapid Release 32-bit Expected to work Firefox Rapid Release 64-bit Expected to work Firefox Extended Support Release 32-bit Yes Yes Firefox Extended Support Release 64-bit Yes Google Chrome Yes Safari on macOS Yes Not Certified

- 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. Performance Comparison

Editor's Notes
- #4: Java Web Start provides a browser-independent architecture for deploying Java 2 technology-based applications to the client desktop. Java Web Start software is installed as part of the Java Runtime Environment (JRE) software. Users do not have to install Java Web Start software separately or perform additional tasks to use Java Web Start applications With Java Web Start, users can launch a Java application by clicking a link in a web page. The link points to a Java Network Launch Protocol (JNLP) file, which instructs Java Web Start software to download, cache, and run the application. This way, users can download and launch applications without going through additional installation procedures.
- #5: Some browsers are Phasing NAPI Plugin Support. Some browsers never had NAPI Plugin Support. The same web browsers used in the current architecture will continue to be supported (Microsoft Internet Explorer, Mozilla Firefox ESR, and Apple Safari). Browsers which formerly did not support the Java Plug-in and only supported HTML/OA Framework modules (such as Google Chrome and Microsoft Edge) will be able to launch Forms and Java applets in Oracle E-Business Suite using Java Web Start.
