How will IBM Host On Demand work on browsers that no longer support Java plug-ins, and Oracle stops supporting Web Start?
Short answer: It won't, at least not as you expect it to.
When Mozilla announced the end of NPAPI support in August 2018 from Firefox 52 and Oracle announced the deprecation of the Java Applet in Java 9, IBM Host on Demand customers started to encounter browser-based access issues. Without the Java plug-in, applets cannot work within the updated browsers. This made cached and plugin client variants of Host On Demand unusable. Customers found that the following would not work on the browsers that did not support java plug-ins:
All the default pages that use either cached or download clients are affected, including:
HOD Administration client
Database On Demand client
New User creation applet
Cached and Download client pages created with the HOD Deployment Wizard
Portlets created with the HOD Deployment Wizard
Custom Programmable HOD applets
Session Manager APIs to communicate between JavaScript and HOD Applets
Despite these challenges, some customers persisted with HOD, using the Web Start workaround. That was until recently, when Oracle announced end of support for Web Start. Many organizations are now looking to completely remove any Java reliance, especially with something as critical as their mainframe access.
The solution
Host On Demand customers should consider alternative, zero client terminal emulators to access their applications, like Jubilant Terminal Emulator.
