eXtensible Server Pages ( XSPs )

• An XSP page is an XML page with following requirements:

  • The document root must be <xsp:page>
  • It must have language declaration as an attribute in the <xsp:page> element.
  • It must have namespace declaration for xsp as an attribute in the <xsp:page> element.
  • For an XSP to be useful, it must also require at least an <xsp:logic> and an <xsp:expr> element.

• An XSP page is used by a generator to generate XML document.

<?xml version="1.0" encoding="ISO-8859-1"?>

<xsp:page language="java"

xmlns:xsp="http://apache.org/xsp">

<xsp:logic>

static private int counter = 0;

private synchronized int count()

{

return counter++;

}

</xsp:logic>

<page>

<p>I have been requested <xsp:expr>count()</xsp:expr> times.</p>

</page>

</xsp:page>
