Fixing JAR File Download Error After EBS R12.2 Clone

When working with Oracle E-Business Suite R12.2, it’s common to encounter unexpected issues after performing a clone. Recently, after a clone activity, a few users faced errors while trying to access form pages.

Issue

Users were unable to load forms and encountered the following error:

ExitException[3]com.sun.deploy.net.FailedDownloadException:
Unable to load resource: http://xxxxxxxx.yyyyyy.zzz:xxxx/OA_JAVA/oracle/apps/fnd/jar/fndbalishare.jar
at sun.plugin2.applet.JNLP2Manager.downloadResources(Unknown Source)
at sun.plugin2.applet.JNLP2Manager.prepareLaunchFile(Unknown Source)

at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)


Analysis

• Verified the Java exception list – it was working fine.

• Checked whether the application URL was added to the trusted sites – it was missing.

• Tested with SYSADMIN credentials in multiple browsers – the same issue persisted.

• Reviewed browser settings to confirm if insecure content was allowed – it was not.

Solution

The issue was resolved by making the following changes on the client side:

Add the application URL to trusted sites in the browser settings.
Allow insecure content for the application URL.
After applying these changes, users were able to access the forms without any errors.
