Problems setting xsl:param from processor

I have a stylesheet with

         <xsl:param name="foo" select="'bar'"/>

and later

         <xsl:value-of select="$foo"/>

which does the job.   However, when I try to set the parameter in the 
calling Java

         processor.setStylesheetParam("foo","newVal");
         processor.process(
             new XSLTInputSource(....),
             new XSLTInputSource(....),
             new XSLTResultTarget(....));


The value is always the empty string "".

Can anyone help?

Thanks

Fergus

Try this instead:
   processor.setStylesheetParam("foo", new XString("newVal"));
Or this:
   processor.setStylesheetParam("foo", "'newVal'");
   (note the extra set of quotes)

The setStylesheetParam method that takes a string as a second argument
is expecting an expression, so in your case it will look for a node
called 'newVal'.

Hope this helps,
Chris

setStyleSheetParam is expecting a string representing an XPath.  You're
trying to select all newVal nodes.  Try

  processor.setStylesheetParam("foo", "'newVal'");

Notice the apostrophes inside the quotes, just like your xsl:param
expression.

HTH,
