Hi Ivan, > String value = > "org.apache.xalan.xsltc.runtime.TransformerFactoryImpl"; Try "org.apache.xalan.xsltc.trax.TransformerFactoryImpl". I didn't see org.apache.xalan.xsltc.runtime.TransformerFactoryImpl class. And read release notes for XSLTC. Its team claims that not all of TRAX has been implemented in XSLTC yet. Probably javax.xml.transform.dom is the case.

Hello friends, I tried to use XSLTC transformation instead of the "original" xalan transformation. According to the notes I did: 1) put all of the jars in the classpath : ....., xsltc.jar, runtime.jar, BCEL.jar, Jlex.jar, java_cup.jar, ..... 2) set the properties: String key = "javax.xml.transform.TransformerFactory"; String value = "org.apache.xalan.xsltc.runtime.TransformerFactoryImpl"; Properties props = System.getProperties(); props.put(key, value); System.setProperties(props); 3) ran our program and got an error : (listed bellow) If I go back and set the properties to org.apache.xalan.processor.TransformerFactoryImpl we don't have problems. Ok. What does our program do? We have a (base) servlet that does : TransformerFactory tFactory = TransformerFactory.newInstance(); Document pXMLSource = getXML(); String xslData = getXSL(); ByteArrayInputStream pXSLSource = new ByteArrayInputStream(xslData.getBytes()); Transformer transformer = tFactory.newTransformer(new StreamSource(pXSLSource)); if (pXMLSource != null) transformer.transform(new DOMSource(pXMLSource), new StreamResult(out)); So every servlet that extends this servlet feeds: ---> the appropriate XSL file as a (java.lang.String) ; --->and the appropriate XML as (org.w3c.dom.Document); Then we transform. Please tell me why it doesn't work with the XSLTC processor. I looked in the sources and my suspicion is that because we feed the XSL as a string we don't have any URI attached - we feed just plain string (not File ). Your help is very appreciated.
