XSL does not compile when and only I use xalan:evaluate.

Setting in system properties

sysProps.setProperty("javax.xml.transform.TransformerFactory", "org.apache.xalan.xsltc.trax.SmartTransformerFactoryImpl");

XSLT snippet

<xsl:stylesheet version="1.0"  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  xmlns:xalan="http://xml.apache.org/xalan" exclude-result-prefixes="xalan">

<xsl:template name="my_test_template">
<xsl:param name="my_test_param" />

<xsl:if test="xalan:evaluate($my_test_param)">
some statements
</xsl:if>

<xsl:if test="not(xalan:evaluate($my_test_param))">
some statements
</xsl:if>

</xsl:template>

ERROR LOG

ERROR:  'Cannot find external method 'org.apache.xalan.lib.Extensions.evaluate' (must be public).'

You could try using exslt with the dyn-prefix instead of xalan e. g.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    extension-element-prefixes="dyn exslt"
  xmlns:exslt="http://exslt.org/common"
  xmlns:dyn="http://exslt.org/dynamic">

and in your templates:

<xsl:when test="dyn:evaluate(concat('/data/description/entry/text-', $lang, '/text()'))">

gokulak, if you need help using XSLT with Java then you will have to look elsewhere. This forum is for Symphony CMS, a PHP-based content management system.
