To pass information between JSP and XSL you can use either the DOM directry - or you can pass parameters. To do this check out this sample jsp page:

<%@ page language="java" import="java.util.*,corinis.*,corinis.modules.*" %>
<%
Core core = new Core (pageContext); // init the core module

Forum f = (Forum)core.getModule(Forum.class);
core.addDom(f.getEntries());
core.addXslParameter("manage", String.valueOf(core.checkAuthority("FORUM_MANAGE")));
core.addXslParameter("yourParam", "cool"));
out.print(core.parseDom("test.xsl", true));
%>

in the xsl you can then easily use these parameters (and quite a few default parameters)

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
        <xsl:param name="manage"/>
        <xsl:param name="username"/>
        <xsl:param name="yourParam" select="'ok'"/>
        <xsl:template match="/">
                <h1>Manage the Forum: <xsl:value-of select="$manage"/></h1>
                 <xsl:value-of select="$username"/> is <xsl:value-of select="$yourParam"/>
        </xsl:template>

</xsl:stylesheet>

Default parameters include:

• username
• userid
• session - the session id
• date - the current date in a formatted way
