These method is called by the XSLT processor when an xsl:import function in your XSLT is found. Then, If you write your own URIResolver [2], you can load your xsl file in cache and give it to the XSLT Processor... TransformerFactory factory = TransformerFactory.newInstance(); factory.setURIResolver(new MyResolver(...)); class MyResolver implements URIResolver { public Source resolve(String href,String base) { // manage your cache and return a Source to the Processor } } [1] http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/transform/TransformerFactory.h tml#setURIResolver(javax.xml.transform.URIResolver) [2] http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/transform/URIResolver.html HTH Fred -- XPath free testing software : http://lantern.sourceforge.net Frédéric Laurent http://www.opikanoba.org XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
