Class XMLValidationFilter

java.lang.Object
  org.dlese.dpc.webapps.servlets.filters.FilterCore
      org.dlese.dpc.webapps.servlets.filters.XMLValidationFilter

All Implemented Interfaces:

Filter

Deprecated. Use XMLPostProcessingFilter instead

public final class XMLValidationFilter
extends FilterCore

Performs XML validation and gzipping of the pre-compiled HTTP response content. A caller wishing to invoke this filter should use an HTTP request parameter 'rt' set to 'validate.'

This is implemented using a servlet response Filter that checks the content for validity against an XML schema or DTD, which must be referenced in the content itself. This filter also perform gzip compression of all output, if supported by the browser. See More Servlets and JavaServer Pages, chapter 9 for more information on Filters.
