Call Java methods from within the XSLT

Define the namespace prefix (use Class Name) and bind this prefix to the Java Class object

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xmlns:Math="http://www.math.org/">
  <xsl:script implements-prefix="Math" language="java" src="java:java.lang.Math"/>
  ...
</xsl:stylesheet>
					

Define the Java method name using the local-name of the XPath function

  <xsl:template name="test">
    <value-of select="Math:min( 100, 101)"/>
  </xsl:template>
					

Construct a new Java Object using new()

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xmlns:Math="http://www.date.org/">
  <xsl:script implements-prefix="Date" language="java" src="java:java.util.Date"/>

  <xsl:template name="test">
    <variable name="date" select="Date:new()"/>
    <value-of select="Date:toString( $date)"/>
  </xsl:template>
</xsl:stylesheet>
					

Convert the arguments to Java Objects

  <xsl:template name="test">
    <value-of select="Math:min( number( @value1), number( @value2))"/>
  </xsl:template>
					

Handle the return value.
