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);
}
}
}
Yes, that looks nice.
Basically every pipeline component uses URLs to access resources. That's
why I think there should be a rather easy way to support authentication
in each and every component currently in existence.
I have created a new Jira issue for this
(https://issues.apache.org/jira/browse/COCOON3-35) to keep track of the
progress and collect all relevant information there.
We will have to do some refactoring to provide a flexible and easy way
that is working for the components we have now and the ones that will
come in the future, but I'm very confident that this easily done.
Please feel free to add your comments and thoughts to the issue...
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!
Very glad to hear this, of course. Thank you!
Steven
Cheers, Nils
Hello Nils,
I'm afraid there is currently no support for accessing URLs that
require authentication.
While I think this is a feature all components should have, it
will take some time to add this and you'd have to wait for the
next release or change to the trunk in order to use it.
A faster way would be to create a new XSLTTransformer and add the
authentication to it.
The code for accessing the URL (currently in the
createTransformerHandler() method) should look like this (just top
off my head, no guarantees ;-) )
String userPassword = "Username" + ":" + "Password";
String encoded = new
sun.misc.BASE64Encoder().encode(userPassword.getBytes());
URLConnection connection = this.source.openConnection();
connection.setRequestProperty("Authorization", "Basic " +
encoded);
InputStream inputStream = connection.getInputStream();
InputSource inputSource = new InputSource();
inputSource.setByteStream(inputStream);
XMLReader xmlReader = XMLReaderFactory.createXMLReader();
xmlReader.setContentHandler(templatesHandler);
xmlReader.parse(inputSource);
inputStream.close();
But as I said above, this is a sound feature request and you can
expect this to be in one of the next releases...
Regards,
Steven

Hi all,
I just started trying out cocoon 3 alpha 1 and I'm wondering
if there is a solution for the following scenario: I'm
retrieving all my XML and XSLT content via URLs that require
authentication. Without the authentication I could simply
create a pipeline like this:
...
Pipeline pipeline = new NonCachingPipeline();
pipeline.addComponent(new StringGenerator("<x></x>"));
pipeline.addComponent(new XSLTTransformer(new
URL("http://example.com/somexslt.xslt";)));
pipeline.addComponent(new XMLSerializer());
ByteArrayOutputStream baos = new ByteArrayOutputStream();
pipeline.setup(baos);
pipeline.execute();
...
That's almost the same as the example on the cocoon website.
The only difference is that instead of a file I'm using a URL
to provide the XSLT. This works if I disable authentication
for my XML/XSLT repository. But when I enable authentication,
I'll end up with an exception and a 401 from apache somewhere
in the stack trace...
So in short: I'm wondering if there is a way to create an
XSLTTransformer that can retrieve data from URLs that require
authentication?
Any help would be greatly appreciated! Cheers, Nils
