Class MakumbaResponseWrapper

java.lang.Object
  javax.servlet.ServletResponseWrapper
      javax.servlet.http.HttpServletResponseWrapper
          org.makumba.controller.MakumbaResponseWrapper

All Implemented Interfaces:: HttpServletResponse, ServletResponse

public class MakumbaResponseWrapper
extends HttpServletResponseWrapper
extends HttpServletResponseWrapper

This class provides a wrapper around a HttpServletResponse, and modifies on the fly some of the output to be written. In detail, these modifications are:

At the begin of the <head> tag, a the Makumba CSS style sheet is injected.
At the end of the <head>, the required Javascript libraries are included.

These modifications, especially inclusion of the Javascripts are needed for certain functionality of the Makumba Tag Library, such as LiveValidationProvider and AJAX features (e.g. SectionTag)
Note that the modifications are only applied on the MakumbaResponseWrapper.MakumbaPrintWriter provided by the getWriter() method, but not on the OutputStream.
