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 _OracleOasis._jspService (_OracleOasis.java:662) .... "
This has been observed in e-BS 12.1.2 with Discoverer 10.1.2.3.
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 188.8.131.52 with Discoverer 10.1.2.2.
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 10.1.2.2 + 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.
