示例1: _getResponseWriter
import javax.faces.context.ExternalContext; //导入方法依赖的package包/类
private static ResponseWriter _getResponseWriter(FacesContext context)
throws IOException
{
ExternalContext external = context.getExternalContext();
String contentType = "text/html";
String encoding = "UTF-8";
external.setResponseContentType(contentType);
external.setResponseCharacterEncoding(encoding);
ResponseWriter rw = context.getRenderKit().createResponseWriter(
external.getResponseOutputWriter(),
contentType,
encoding);
context.setResponseWriter(rw);
return rw;
}
示例2: _processRender
import javax.faces.context.ExternalContext; //导入方法依赖的package包/类
private void _processRender(UIComponent viewRoot)
{
ExternalContext extContext = _context.getExternalContext();
extContext.setResponseContentType(_RESPONSE_CONTENT_TYPE);
extContext.addResponseHeader("Pragma", "no-cache");

// the ViewState as a hidden element during its postscript element rendering

// launder the IOException as a FacesException, we'll unwrap this later
