How do you use Xalan-J "-param" option?

[mountainbiker]

I cannot seem to get the -param command-line option of xalan to work.

command-line

java org.apache.xalan.xslt.Process 
    -in a.xml -xsl a.xsl -out a.html -param

a

 1

xml

<?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?>
<A></A>

xsl

<?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?>
<xsl:stylesheet version=&quot;1.0&quot; xmlns:xsl=&quot;[URL unfurl="true"]http://www.w3.org/1999/XSL/Transform&quot;>[/URL]
    <xsl:template match=&quot;/&quot;>
	    <h1>[<xsl:value-of select=&quot;

$a

&quot;/>]</h1>
    </xsl:template>
</xsl:stylesheet>

error

could not find the variable with name of

a

Well, I cannot explain why it was not working. I reloaded the java and xalan, and it corrected the problem. Now, it works like the documentation describes.
