  Modified:    java/samples/servlet XSLTServletWithParams.java
  Added:       java/samples/servlet fooparam.xml fooparam.xsl
                        UseStylesheetParamServlet.java
  Log:
  1. Added UseStylesheetParamServlet, submitted by
  Paul Campbell <se...@halcyon.com>.
  2. Following the example set by UseStylesheetParamServlet,
  I changed XSLTServletWithParams to use
  request.getParameter() rather than request.getParameterValues()
