[rules-users] Use Knowledge Agent

[Michael Anstis]

Hi,

#2

You could try setting the basicAuthentication, Username and Password
properties on UrlResource before adding it to the builder:-

<snip>
    builder.add(ResourceFactory.newUrlResource(url), ResourceType.PKG);
</snip>

<snip>
    UrlResource urlResource = ResourceFactory.newUrlResource(url);
    urlResource.setBasicAuthentication("enabled");
    urlResource.setUsername("Smurf");
    urlResource.setPassword("Smurfy");
    builder.add(urlResource, ResourceType.PKG);
</snip>

When you shift to using change-sets you should be able to embed the basic
authentication in the change-set.xml file (as per my previous link) - your
example code isn't using KnowledgeAgent yet; simply a URL resource.
