How to pass parameters from JSP into a transformation

[Robinson Simon <Si...@newton.co.uk>]

Hi All,

I have a HTML form from which I want to enable the users to select from a drop down list. I then want to pass the values into a JSP page. The JSP will call a bean to do the transformation of some XML using a stylesheet to select the required information.

I can call the required classes using JSP tags and that returns information requested. The parameters in the XSL are currently hard coded. I want to know is it possible to pass the values into the transformation from the Java code calling the XSL/XML.


Regards

Simon

You can declare "global parameters" in your stylesheet by defining
xsl:param tags at the "top level", ie as direct children of the
xsl:stylesheet tag:

<xsl:param name="foo" select="default-value-for-foo"/>

You can then invoke method
 setParameter("foo", "special-value-for-foo");
on your Transformer object before starting the transformation.

Your stylesheet will then see the special value.

I hope this is what you were looking for.
