XSLT.java

import javax.xml.transform.TransformerFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.URIResolver;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import java.io.FileReader;

class XSLT {

    public static void main(String[] args) throws Exception
    {
        TransformerFactory factory = TransformerFactory.newInstance();
	URIResolver resolver = new CleanHtmlURIResolver(factory.getURIResolver());
	factory.setURIResolver(resolver);
        Transformer transformer = factory.newTransformer(new StreamSource(new FileReader(args[0])));
	// http://osdir.com/ml/text.xml.resin.user/2003-06/msg00027.html
	transformer.setURIResolver(resolver);
        transformer.transform(resolver.resolve(args[1], ""), new StreamResult(System.out));
    }
}

CleanHtmlURIResolver swallows exceptions (empty catch block). Is there better way how to handle exceptions? Should they be wrapped by TransformerException?
