Re: [rules-users] Drools and Guvnor 5.1M2 - Exception being thrownin processChangeSet

The problem seams to happen because the kagent can't access the url. If you try to access the change set xml using a browser, does the browser ask you for authentication? I don't know why, but guvnor protect its urls since 5.1 I think. So, basically, the error is that guvnor can't read from the url. The same error happens if you provide a non existent url. I need to open a jira for this. As a work around, try doing this: <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set drools-change-set-5.0.xsd<http://drools.org/drools-5.0/change-setdrool... <add <resource basicAuthentication='enabled' username='admin' password='admin' source=' http://ruleserver/drools-guvnor/org.drools.guvnor.Guvnor/package/my.rule.... type='PKG' / </add </change-set Remember to replace username and password.
