Java Look and Feel settings cause java.lang.NullPointerExcerption or java.lang.NoSuchFieldError when trying to Start Discoverer from e-Business Suite (Doc ID 554817.1)

Last updated on OCTOBER 17, 2019

Applies to:

Oracle E-Business Suite Technology Stack - Version 10.1.2 to 10.1.2 [Release 10.1]
Information in this document applies to any platform.

In E-Business Suite with any version of Discoverer,  when Discoverer Viewer or Plus is launched from E-BS with JInitiator, a Java exception error stack occurs :

"Exception found :


at oracle.apps.fnd.util.URLEncoder.encode(

at _OracleOasis._jspService ( .... "

This has been observed in e-BS 12.1.2 with Discoverer

If JInitiator is used, it may also be observed that Discoverer pastes &LookAndFeelName=OracleLookAndFeel or &LookAndFeelName=BrowserLookAndFeel into the URL, causing JInitiator to deliver the following error message to the screen:

"Exception occurred during event dispatching: java.lang.NoSuchFieldError: LIGHT_GRAY" .

It is possible to reproduce the latter message by pasting &LookAndFeelName=OracleLookAndFeel manually into the URL.

This has been observed in e-BS with Discoverer


The first scenario was reproduced by upgrading e-Business Suite from 12.0.6 to 12.1.2. It could not be reproduced in 12.1.1.

The URL scenario has been reproduced by applying Discoverer + Cumulative Patch 5.

However neither has anything to do with the Discoverer patch level or anything in Discoverer.
The issue is in the FND code and core e-BS configuration settings encountered by Discoverer.
