[rules-users] Drools Guvnor Repository Reports

[Aseem Belsare]

Yes I have. I tried to do something similar to get the version history from
Guvnor, but then I get exceptions which seem to be related to REST API and
not Guvnor. I have no idea why this is happening.

Code:
        URL url = new URL(guvnorURI + "/" + packageName +"/"+"versions");

        HttpURLConnection con = (HttpURLConnection) url.openConnection();
        con.setRequestMethod("GET");
        con.setRequestProperty("Accept", MediaType.APPLICATION_ATOM_XML);

        String userPassword = "admin" + ":" + "admin";
        String encoding = new
sun.misc.BASE64Encoder().encode(userPassword.getBytes());
        con.setRequestProperty("Authorization", "Basic " + encoding);

        con.connect();

        InputStream versionHistory = con.getInputStream();

        Abdera ab = new Abdera();
        Document<Feed> doc = ab.getParser().parse(new
InputStreamReader(versionHistory));
        Feed feed = doc.getRoot();

        List<Entry> entries = feed.getEntries();

        for(Entry entry : entries){
            System.out.println(entry.getTitle());
            System.out.println(entry.getUpdated());
            System.out.println(entry.getAuthor());
        }
        .
        .
        //remaining code.

Exception: thrown at *Document<Feed> doc = ab.getParser().parse(new
InputStreamReader(versionHistory));*

Any ideas?
