Hi Steven,
thanks for your reply, I created a new XSLTTransformer for now, based on the
code you suggested in your mail. Since we're talking feature requests, I
think it would also make sense to provide a PipelineComponent that allows to
access XML documents through authenticated URLs. I'm using the following for
now:
...
public class AuthenticatedUrlXmlProducer extends AbstractXMLProducer
implements Starter {
private URL url;
private String username;
private String password;
public AuthenticatedUrlXmlProducer(URL url, String username, String
password) {
super();
this.url = url;
this.username = username;
this.password = password;
}
public void execute() {
try {
String encoding = new sun.misc.BASE64Encoder().encode((username
+ ":" + password).getBytes());
URLConnection uc = url.openConnection();
uc.setRequestProperty("Authorization", "Basic " + encoding);
XMLUtils.toSax(uc.getInputStream(), this.getXMLConsumer());
} catch (IOException e) {
throw new ProcessingException(e);
}
}
}
I think the alpha release of Cocoon 3 looks great and I'm looking forwards
to see where the journey is going with the first beta!
Cheers, Nils
