Alternative Ways for Launching Oracle Forms in 2023


Microsoft’s announcement to officially retire Internet Explorer in June 2022 has dealt another blow to organisations that rely on applications built with Oracle Forms.

This latest announcement follows the trend of major browsers dropping the support for Java Applets, and the underlying NPAPI technology that Oracle Forms relied on to run in the browsers, in favour of modern HTML5, due to security issues. 

Over the last couple of years, Internet Explorer has been the only browser in which organisations have been able to run Oracle Forms online since 10g. Therefore, this announcement could have major ramifications for businesses and organisations which have a dependency on Oracle Form applications. 

With that in mind, what options do you have for running forms moving forwards? 

Internet Explorer Mode

As part of the announcement, Microsoft has stated that Edge will continue to include an “Internet Explorer” mode. This will continue to allow you to run Oracle Forms in the browser using the NPAPI plugin, however, this comes at the expense of user experience. For example: 

  • Internet Explorer mode is NOT enabled by default. This has to be manually enabled in the Edge browser settings for each user.
  • The only way to run a webpage including Oracle Forms is to first run the Oracle Forms URL in Edge which will present a blank page. The user has to manually go into the menu for Edge and go into More Tools. The user must then click on “Reload in Internet Explorer mode” to re-load the application using Internet Explorer mode. The Oracle Forms application will now run normally.
  • If the end-user either closes out of the Forms application or is kicked out due to an error (FRM-92103, FRM-93652, etc.) and then tries to run the URL again to go back into Forms, the user has to experience the blank page again and then re-do the step to reload the page in Internet Explorer mode.

So not only is this a tiresome process, but it could also lead to security issues due to the possible flaws within Internet Explorer. Furthermore, this method requires a local installation of Java, its regular security maintenance, and its licensing.

Forms Standalone Launcher and Java Web Start

For customers running 12c, the latest release of Oracle Forms, there are a couple of options that can be done to run Oracle Forms without the need to use Internet Explorer. These are the Forms Standalone Launcher (FSAL) and Java Web Start (JWS). These methods allow end-users to either launch Oracle Forms applications using modern web browsers such as Chrome, Edge, and Firefox or launch the applications using a script accessible on the desktop. 

Unfortunately, these options are not available to those using Oracle Forms 10g or 11g, therefore you would need to upgrade to 12c to take advantage of these options. This method also requires a local installation of Java, its regular security maintenance, and its licensing.

Oracle APEX

An option that is available to any version of Oracle Forms (6i, 10g, 11g, or 12c) is migration to Oracle Application Express (APEX), which enables you to convert your form into a web-based application supported by all modern web browsers.

This option, which is not viable for third-party applications, can be impractical, due to cost and timeline implications.


CheerpJ, a tool developed by Leaning Technologies, is the only solution on the market to preserve access to Java Applets, including those generated by Oracle Forms, on modern browsers. It allows organisations to extend the life of their legacy applications by making them usable on modern browsers, with no change to their source code, saving them time, money and resources.

So not only does this approach work with any version of Oracle Forms (6i, 10g, 11g, or 12c), it is also available for Organisations that rely on third-party applications. 

This new approach, which relies on modern HTML5, WebAssembly and JavaScript, enables organisations not only to access their applications on mobile devices but also give access to external users. Crucially, by using CheerpJ organisations no longer need their end-user machines to have a local installation of Java.
