I think you're right, as far as the semantics of the ERROR message is
concerned. One reason you can't find a class is because you didn't compile
the source; are you sure you have the _classfile_ available that corresponds
to your BchDate class?
Reason I ask that is, this burned me, too, for about an hour. I never
thought to compile the extension class. When I did, everything worked (i.e.
having FOP do everything all at once as with your command line above).
My final example is very close to yours. Here is the stylesheet root:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:fo="http://www.w3.org/1999/XSL/Format";
xmlns:bchext="xalan://util.BchDate"
xmlns:java="http://xml.apache.org/xslt/java";
exclude-result-prefixes="java">
and here are 2 segments of the stylesheet that shows use of the functions:
<xsl:variable name="format" select="string('EEE MMM dd yyyy')"/>
<xsl:variable name="year" select="'2001'"/>
<xsl:variable name="month" select="'07'"/>
<xsl:variable name="day" select="'18'"/>
...
<fo:block border-right-width="0.5pt" text-align="center"
vertical-align="middle" border-style="solid" line-height="11pt">
<xsl:variable name="formatter"
select="java:java.text.SimpleDateFormat.new($format)"/>
<!-- <xsl:variable name="formatdate"
select="bchext:getDate($year,$month,$day)"/> -->
<xsl:variable name="formatdate"
select="java:util.BchDate.getDate($year,$month,$day)"/>
<xsl:value-of select="java:format($formatter,$formatdate)"/>
</fo:block>
My BchDate.java is identical to the Xalan IntDate.java.
I commented out the call to getDate() that uses the class format
declaration; that also works just fine.
