Servlet Error In Oracle Portal 11.1.1.x Relating To GITO (Doc ID 1502424.1)

Last updated on MARCH 08, 2017

Applies to:

Portal - Version 11.1.1.4.0 to 11.1.1.7.0 [Release FMW11g]
Information in this document applies to any platform.

Symptoms

After upgrading Oracle Portal to 11.1.1.4 users are seeing a 'Servlet Error' message in their browser when attempting to navigate to the Portal:

Servlet Error
An unexpected servlet error was encountered.
Please check the log file for more details.

This is not happening for everyone, on every request, but seems to occur after a user has logged in or logged out.

Or after re-visting the Portal after the session has been left inactive after some time, i.e. the error can occur when re-visiting portal in a browser which has previously been used to login.

 

Please note:

It has also been found that the issue can occur as the result of implementing GITO in the affected (upgraded) versions.  It can also be seen in 11.1.1.6.0 Portals.


Changes

 Upgraded to Oracle Portal 11.1.1.4 or later.
