Oracle Application R12 | Using Microsoft Edge Chrome for versions 11 & 12.0.xx

Updated on 8th October 2021 for Microsoft Edge Version 94.0.x.x & for Windows 11 that comes without Internet Explorer (or it doesn’t allow you to start Internet Explorer)

A much easier method is available with versions later than the one I used earlier.

Step# 1. Go to Edge settings (type edge://settings in the address bar and select “Default Browser”

Change “Allow sites to be reloaded in the Internet Explorer mode” to “Allow”, that will require you to restart the browser. Please restart

Step# 2. Now enter the address of your Oracle Application in the address bar and wait for the login page to load. Once loaded, click on the “three dots” menu by the extreme right of the browser and select “Reload in Internet Explorer mode”

This will open another dialog box as seen with the above image. Toggle “Open this page in Internet Explorer mode next time” and click “Done” button, that will produce more notifications like the one you could see with the below image.

It asks you to leave the Internet Explorer mode and another button “Show in toolbar”. This is an interesting button, clicking that starts showing a small tool button in the tools area and the button will reload the current page in “Internet Explorer mode”.

That’s all. Just click the toolbar button and your Oracle Application login page will be loaded in “Internet Explorer mode” immediately.

Toggling the switch to “Open this page in Internet Explorer mode next time” in the “Step# 2” adds an entry to “Internet Explorer mode pages” area for your current page and the entry is valid for next 30 days. Microsoft is expecting you to modernize your “page” within those next 30 days ;). Once this entry expires, you must get the “Open this page in Internet Explorer mode next time” dialog box once again.

October 8, 2021 update ends here.

After 25 years ever since it was launched, Windows 11 will be the first OS that is not shipping with Internet Explorer.

How does this matter to Businesses those use Oracle Application versions 11 & 12.0.xx? Well, currently Internet Explorer is the only one browser that allows to load Oracle JRE (NPAPI client) for Oracle Forms, on which much of the Oracle module rely.

Oracle Applications has patched the latest releases with a technology called JWS (Java Web Start), that let’s the users to download a jnlp file from the application and Oracle Java Run Time to start in desktop mode (without being loaded in a browser session) loading Oracle Forms. Well, this enhancement is not available for Application versions 11 & 12.0.xx

Microsoft was expecting a huge cry from the Businesses that use Oracle Applications/legacy implementations those cost millions of dollars and fine tuned for Internet Explorer. Cutting these businesses could mean loads for Microsoft, So they have integrated “IE Mode” into their chromium based “Edge browser”, which is the default browser on Windows 11. IE Mode makes Edge Chrome to “act” as if it were Internet Explorer for legacy Web based applications & loads NPAPI clients like JRE.

Today let us see how to configure Microsoft Edge Chrome for Oracle Applications.

Start Microsoft Edge Chrome & open “Settings”

Click on Default Browser & spend a moment to check currently set options.

Let us change few of those settings like shown below.

Let Internet Explorer open sites in Microsoft Edge -> Change to Allow

Allow sites to be reloaded in Internet Explorer mode ->Change to “Allow”. This will require you to restart the browser.

You must add the sites those you want to open in IE mode by clicking “Internet Explorer mode pages” Add button. Such pages will have maximum 30 days validity. Without, JRE will not load and will prompt you to download it from the default location.

Now, let us click the restart button & give it a try.

That’s all folks.

Oracle Applications R12 | Java applet font scaling issues

We are using Oracle applications R12 12.0.6 with JDK 6.0 while most of the clients are using JRE 7/8 based on different business requirements (With full knowledge that there would be unexpected results due to the compiled versions). We’ve observed a peculiar issue with the JRE applet once after the upgrade to Windows 10 version 1803. The Java applet started showing too small fonts while launched from displays with high DPI resolutions.

Digging in brought me to the following discussion:

Although there are multiple recommendations, for EBS environment, Please follow the below instructions:

Launch the JAVA applet by opening a forms based module.

Open task manager and locate “Java(TM) Platform…”, right click and open properties. This will open the properties for “jp2launcher.exe”. Click on “Compatibility” and click on “Change high DPI settings”. Now check “Override high DPI scaling behavior. Scaling performed by:” to “Application”. Refer the image for more details.

Once the changes are made to the properties of the executable, restart the box. It could be specific case, the changes were not applied until a restart for me.

Although it fixes the font scaling issues, the toolbar area of the Oracle forms are remains scaled with pretty small icons. I am yet to find out a fix for this minor annoyance. May be quite soon.




Oracle Applications R12 | Using JRE 7 for application access

Update 18th April 2015: You can use java version “1.8.0_45” (JRE 8 update 45) Using the same hacks mentioned below!

You may have to restart your BOX once after Java Runtime 7 update 51 or later installed. Once the box restarted, JRE should start loading properly with Internet Explorer 11

UPDATE: If your E-Business Suite environment is not updated to Java 7, please do not update your JRE above 51! We tried the latest JRE7 update 55 and found that the applet was not at all loading. Were forced to rollback to the earlier version

Stuck with JRE 6 update 45 and sites like does not work properly without JRE 7?

Well there is a work around, as mentioned with the Oracle blog

Which works extremely beautiful with both Internet Explorer 10/11 & Google Chrome once after JRE is upgraded to version 7

Update: if you are using multiple Oracle products, system level variable setting for  JAVA_TOOL_OPTIONS could problematic. You can override this issue by changing the run time parameters for JRE like following

Control panel->Java(32-bit)->Click on Java tab->Click View-> Add the following to appropriate Product “Runtime Parameters” column (by pasting, or typing in)

-Djava.vendor="Sun Microsystems Inc."

So what you are waiting for?

Common “errors” and solutions

1. The first error you may receive once after the JRR upgrade should be

“Application Blocked by Security Settings”



Go to control panel->Open up Java(32)->Security Tab


Adding the specific site should override the above Application Blocked lockout

2. Java Security Warning Dialogue windows where you must exclusively accept the security warning twice

“I accept the risk and want to run this application”


Which is going to be a permanent element with JRE 7 update 10 and later, according to multiple sites for the applications which are not signed. This warning will be issued each and every time (Not for the same session) and until now no hacks are available to suppress it from appearing. If you want to use JRE 7, just live with it.

The same warning will be displayed twice, and you MUST accept the warning both the times in order to let the java to load your forms based application(s)
