BSFException when using Javascript in XSL

[Frank]

Hey all,

I can't seem to get javascript running in my XSL document.

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:xalan="http://xml.apache.org/xalan"
xmlns:my-ext="ext1" extension-element-prefixes="my-ext">
<!--The component and its script are in the xalan namespace and
define the
implementation of the extension.-->
<xalan:component prefix="my-ext" functions="hi">
<xalan:script lang="javascript">
function hi() {
return 5;
}
</xalan:script>
</xalan:component>
<xsl:template match="/deadline">
<xsl:value-of select="my-ext:hi()"/>
</xsl:template>
</xsl:stylesheet>

I get this huge stack trace:
