RE: Problem calling external java method

[Chris Bare]

Thanks a ton. That way works!

It seems that the crucial difference is putting the
fully-qualified-classname (mypackage.MyClass) in the namespace rather
than in the select attributes. For example this works just fine:


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:java_util_date="http://xml.apache.org/xalan/java/java.util.Date";
  version="1.0">

  <xsl:output method="xml"/>
  <xsl:variable name="now" select="java_util_date:new()"/>

  <xsl:template match="/">
    <foobar>
      <xsl:attribute name="square">
        <xsl:value-of select="java_util_date:toString($now)"/>
      </xsl:attribute>
    </foobar>
  </xsl:template>

</xsl:stylesheet>

...while this fails trying to find a static method:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:dammit="http://xml.apache.org/xalan/java";
  version="1.0">

  <xsl:output method="xml"/>
  <xsl:variable name="now" select="dammit:java.util.Date.new()"/>

  <xsl:template match="/">
    <foobar>
      <xsl:attribute name="square">
        <xsl:value-of select="dammit:java.util.Date.toString($now)"/>
      </xsl:attribute>
    </foobar>
  </xsl:template>

</xsl:stylesheet>

java.lang.NoSuchMethodException: For extension function, could not find
method static java.util.Date.toString([ExpressionContext,] #UNKNOWN
(java.util.Date)).

I wonder if this is the intended behavior. I was originially thinking
the only difference between calling a static method and an instance
method was whether you pass in the instance as a parameter.

I haven't tried all the permutations, but the
http://xml.apache.org/xalan/java/ namespace seems to be optional.

Anyway, huge thanks to John!!

Chris,

I declare my extensions, in interpretive mode, a bit differently. I
think the java namespace may have special meaning. The example below
declares a class called CategoryPageMgr that exists in the custom
package.

<xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0"
    xmlns:catmgr="custom.CategoryPageMgr"
    exclude-result-prefixes="catmgr"
    extension-element-prefixes="catmgr">

    <xsl:param name="CategoryMgr" select="catmgr:new()"/>
   
    <xsl:template match="foo">
       <data>
           <xsl:value-of select="catmgr:getCategoryPage($CategoryMgr, 
$category, $localID, $pageData)" />                   
       </data>
    </xsl:template>

</xsl:stylesheet>

Hope that helps
John G
