Exception during processing XSLT transformation!
- by Artic
I'm using this code to generate contents file. 
try {
        StreamResult result = new StreamResult();
        TransformerFactory tf = TransformerFactory.newInstance();
        Templates templ =  tf.newTemplates(xsltSource);
        Transformer transf = templ.newTransformer();
        for (String item: groups){
            item = item.replaceAll(" ", "-").toLowerCase();
            result.setOutputStream(new FileOutputStream(path+item+".html"));
            transf.clearParameters();
            transf.setParameter("group", item);
            transf.transform(xmlSource, result);
        }
    } catch (TransformerConfigurationException e) {
    throw new SinkException(e.getMessage());
    } catch (TransformerException e) {
    throw new SinkException(e.getMessage());
    }
But on second iteration I have an exception 
ERROR: javax.xml.transform.TransformerException: com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: Read error
Cann't understand what is the reason?
