While
working on a J2EE problem with housing bank,
we faced the following error
Servlet error: An exception occurred. The
current application deployment
descriptors do not allow for including it in
this response. Please
consult the application log for details.
The situation arises as follows
We are using OID - SSO based authentication for logging in and logging out of our ADF application (10.1.3.2) running against OC4J 10.1.3
the problem arises when we execute the logout procedure which is similar to
response.setHeader( "Osso-Return-Url", "http://mysite/faces/index.jspx");
response.sendError( 470, "Oracle SSO" );
The error is not enough to understand what is going on, while at the same time, it is not always the case that you can access the log file
If you want to know the complete error
message and stack trace you must deploy the
application in "development" mode. To
achieve this you must perform the following:
Suppose you have a JDeveloper Application
Server connection named "REALSOFT".
 | Right-click the deployment profile and select "Deploy to REALSOFT" |
| In the "Configure Application" dialog box you have the option to edit certain deployment options. |
| Select the web-app on the left side
of the screen. On the right side of the
screen there is an option "development".
Set the value to "true" and deploy your
application. |
or
Using Oracle EM Application Server
Control (on a standalone OC4J 10.1.3.1.0) in
the "Deployment Settings" step while
deploying an application
(1) in the "Advanced Deployment Plan
Editing" section click the "Edit Deployment
Plan" button
(2) in the tree on the left, in the "war"
node, select the web-module
(3) on the "Edit OC4J Descriptor" tab, find
the "development" property and set it to
"true"
(4) click OK
Or you can modify the following file
manually
orion-web.xml file. Here is an example:
<?xml version="1.0"?>
<orion-web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/or
ion-web-10_0.xsd"
deployment-version="null"
deployment-time="1152223108413"
jsp-cache-directory="./persistence"
jsp-cache-tlds="standard"
temporary-directory="./temp"
context-root="/DevelopmentThrowException"
schema-major-version="10"
schema-minor-version="0"
development="true">
<!-- Uncomment this element to control web application class loader
behavior. <web-app-class-loader search-local-classes-first="true"
include-war-manifest-class-path="true" />
-->
<web-app>
</web-app>
</orion-web-app>
After setting the development flag to true
and running the application again, the error
stack appeared on the screen
Cause:
According to Oracle metalink note
567162.1
Solution
workaround
If you do not apply the patch, a workaround
is to invalidate the current session before
redirecting the URL to another session
