The current version of JDeveloper 18.104.22.168 is missing some extensions which are popular in the older version of JDeveloper. One of them, which is asked for a couple of times, is the MAF extension. Other extensions like ‘BI ADF ViewRegions’ are missing too.
Here are the images from the update page of JDeveloper 22.214.171.124
As you see, there is no ‘Mobile Extension’.
In general, you have two options to get the missing extensions installed:
- Download the extension from the ‘Extension Exchange’ and install it from a local file
- Add the ‘Extension Exchange’ to the known sources of extensions and load the extension right from JDeveloper
Personally, I prefer the second way as it only shows the extensions available for your version of JDeveloper. You can only install extensions which are configured for your version anyway.
Extension Exchange on the WWW
You’ll find all extensions available for all version of JDeveloper on the public ‘Extension Exchange’ at
From there you can download an extension and install it in JDeveloper from the local file. When you download an extension make sure to load the right version as you can only install extensions which are configured for your version (check the min and max version of the extension!).
Once you have an extension downloaded you can install it from this local file. As a sample show images how to install a MAF extension from a local file. As a sample, we’ll use JDeveloper 126.96.36.199.
Download the extension to your local file system and remember the folder you saved the file to. In JDeveloper go to menu ‘Help’->’Check for Updates’. Select ‘Install From Local File’ and search the file downloaded
Click finish and the extension gets installed.
If you try to install an extension which is not compatible to your JDeveloper version you get
So make sure you download the right version of an extension you like to install.
URL to add the ‘Extension Exchange’
To avoid the hassle of selecting the right version, let JDeveloper do this work for you. We simply add the URL of the ‘Extension Exchange’ to the ‘Update Centers’ and JDeveloper will search for extensions compatible to your JDeveloper version.
The URL we have to add is:
Open ‘Help’->’Check for Updates’ again and click the ‘Add’ button
Enter a name for the URL and the URL itself and click OK. Now, after clicking ‘Next’ you’ll get
and can select the ‘MAF Extension’ or any other missing extension right from the dialog. The installation is identical to the one shown in the ‘Extension Exchange on the WWW’ section.
