XSPPage

public XSPPage()
Method Detail

init

public void init(Director director)
Description copied from class: AbstractProducer
Initialize the producer setting its context.
Overrides:
init in class AbstractProducer

init

public void init(java.util.Dictionary parameters)

getDocument

public final org.w3c.dom.Document getDocument(javax.servlet.http.HttpServletRequest request)
                                       throws java.lang.Exception
Description copied from class: AbstractProducer
This method is the only one called by the Cocoon engine. Producers are allowed to create streams and this class "mediates" translating these streams into DOM trees. For producers willing to generate DOM trees automatically, they should override this method and may well ignore to implement the getStream() method since it's never called directly by Cocoon.
Overrides:
getDocument in class AbstractProducer

getDocument

public org.w3c.dom.Document getDocument(javax.servlet.http.HttpServletRequest request,
                                        javax.servlet.http.HttpServletResponse response)
                                 throws java.lang.Exception

populateDocument

public abstract void populateDocument(javax.servlet.http.HttpServletRequest request,
                                      javax.servlet.http.HttpServletResponse response,
                                      org.w3c.dom.Document document)
                               throws java.lang.Exception

isCacheable

public boolean isCacheable(javax.servlet.http.HttpServletRequest request)
For backward repository compatibility when upgrading to Cocoon 1.8.1 from an earlier version.
Specified by:
isCacheable in interface Cacheable
