basic question about xalan/xsl param ?

Hi all,
I tried to pass a parameter from java (xalan) to XSLT, and get result after
tranform. In XSL file, it depend on the param passed to call the =
templete and only one templete at moment:
Code Java:
Transformer transformer =3D tFactory.newTransformer(new
StreamSource(Constante.xsltPath));
transformer.setParameter("typeElement",param); //pass the param to XSLT
transformer.transform(source,cible);
XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
    <xsl:output method="text"/>
    <xsl:param name="typeElement" select="/"/>
    <xsl:template>
        <xsl:if test="$typeElement=Var">
            <xsl:call-template name="typeVar"/>
        </xsl:if>
        <xsl:if test="$typeElement=Prca">
            <xsl:call-template name="typePrca"/>
        </xsl:if>
    </xsl:template>

    <xsl:template name="typeVar">
         <!-- Code to transform Var -->
    </xsl:template>

    <xsl:templete name="typePrca">
         <!-- code to transform Prca -->
    </xsl:templete>

</xsl:stylesheet>
But, it doesn't work yet. Some one can help me ?
Thanks !
