Sample integration flow

The integration flow depicted in the recipe is very simple which contains start timer and XSLT Mapping step through which we can leverage the invocation of java function call from XSLT script.

Sample Script

This is the script used in the sample integration flow which starts with namespace declaration and then invokes the java function which display the current date.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:template match="/"
        xmlns:date="java:java.util.Date">
    <xsl:value-of select="date:new()"/>
	</xsl:template>
</xsl:stylesheet>

Sample Output

Output of the Java function invocation from the XSLT script can be experienced in the Monitor's message processing view.
