An error occurred while processing your request" on deploying WebApplications in WebLogic 10.0 and Oracle Application Servers at AGS Java 9.3.1

Error Message

Deploying Web applications at AGS Java 9.3.1 in WebLogic 10.0 and Oracle Application Servers displays the following error message:

"An error occurred while processing your request."

Cause

At ArcGIS Java 9.3.1, the SOAP toolkit has been upgraded to the new ArcGIS Web Services (AgsJWS) toolkit. All new applications created through ArcGIS Manager or the Eclipse/Netbeans plug-ins will use the new ArcGIS Web Services (AgsJWS) toolkit.

Solution or Workaround

Note:
If using WebLogic 9.2 or WebLogic 10.3 as a WebLogic user, it is not necessary to make changes to the deployment descriptor file (weblogic.xml).

For WebLogic 10.0: 

Code:

[XML]

<?xml version="1.0" encoding="UTF-8"?>
<!-- weblogic.xml -->
<weblogic-web-app>
  <container-descriptor>
    <prefer-web-inf-classes>true</prefer-web-inf-classes>
  </container-descriptor>
</weblogic-web-app>

For Oracle Application Server 10GR3:

Code:

[XML]

<?xml version="1.0"?>
<!-- Orion-web.xml -->
<orion-web-app
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/orion-web-10_0.xsd"
  deployment-version="10.1.3.0.0"
  jsp-cache-directory="./persistence"
  jsp-cache-tlds="standard"
  temporary-directory="./temp"
  schema-major-version="10"
  schema-minor-version="0">
  <web-app-class-loader search-local-classes-first="true"/>
  <web-app/>
</orion-web-app>

Note:
The presence of these files does not affect deployment to other application servers.
