/**
* This JSP uses PMA to set param1 in the
* foo.xsl stylesheet before using the
* stylesheet to transform foo.xml
* and outputing the result.
*
* Invoke the jsp from the appropriate
* context for your servlet/jsp server.
* For example: http://localhost:8080/samples/jspSample.jsp?PMA=HellowWorld!&XML=foo.xml&XSL=foo.xsl
* This example assumes that foo.xsl and foo.xml
* are in the same directory.
* Output should be Hello (from foo.xsml) and HelloWorld!
* (value of param1 in foo.xsl).
