Hi,

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.

Hello Michael and Subhas, thanks for your answers.

Apparently the problem is due to permission. I am using the next configuration:

<security:identity authenticate-method="#{defaultAuthenticator.authenticate}"/>
<security:role-based-permission-resolver enable-role-based-authorization="true"/>

I attached the class that use for my test, in this code not included code for authenticate. In that sense I have new questions:

1º What is the minimal configuration of Guvnor for use the Knowledge Agent?

2º What code should be included for authentication?

Thanks and regards,

Give some more details like code and jars in build path. I use KnowledgeBase and working fine for me.

Thanks,
Subhas
