Gets the original, unwrapped portlet response.

Returns:

the unwrapped portlet response

setContentType

public void setContentType(java.lang.String type)

Description copied from interface: VaadinResponse

Sets the content type of this response. If the content type including a charset is set before VaadinResponse.getWriter() is invoked, the returned PrintWriter will automatically use the defined charset.

Specified by:

setContentType in interface VaadinResponse

Parameters:

type - a string specifying the MIME type of the content
