Re: [xsl] calling java functions from xslt

["Vasu Chakkera" <vasucv@xxxxxxxxxxx>]

hi
if u have a class called Helloworld.class that has a method called hello()
then you wud do the following steps.
1. Set the classpath( of Helloworld.class) so that the xalan processor or 
any other processor knows about it.
2. declare the namespace..
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:myprefix = "Helloworld"  extension-element-prefixes ="myprefix">
(u can keep any name ( check the docs for valid names) for the prefix )
u would refer to the java methods with this prefix.

3. Refer to the method hello() that returns some string.
 3.1. If hello() takes no arguments
        <xsl:value-of select="myprefix:hello()"/>
 3.2. If hello() takes arguments like String name
        <xsl:variable name = "arg" select = "'myname'"/>
        <xsl:value-of select="myprefix:hello($arg)"/>
