Chapter 9. Error Handling Configuration

The JBoss Portal request pipeline allows fine-grained, dynamic configuration of how JBoss Portal behaves when errors occur during runtime.

9.1. Error Types

There are several types of errors that can occur during a request:
  • Access denied: the user does not have the required permissions to access the resource.
  • Error: an anticipated error, such as when a portlet throws an exception.
  • Internal error: an unexpected error.
  • Resource not found: the resource was not found.
  • Resource unavailable: the resource was found, but was not serviceable.
