Hi Jarvis,
Thanks for your reply. Looks like i have posted my intension unclearly. To
elaborate bit more, currently i am using Rest API to create KnowledgeBase
from my java client. I have changeset-loans.xml, where my guvnor package
with drl is defined. My java client will this to fire all rules of that
package. In such a case, when i have more one version created for the
package and the rule assets within it, how i can i call specific version
based package along with the drl file to fire all the rule assets belongs to
it? In the same passion, is there any way i can mentioned the rule asset
name in the changeset xml file to fire specific version of rule asset from
java?
Yes, it is possible to specify a specific version of asset in
changeset. though this is not supported by Change-set editor at
the moment, you have to edit the content of change-set xml file
manually. For example, below is generated by change-set editor:
<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
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd'
>
<add>
<resource
source='http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/source'
type='DRL' />
</add>
</change-set>
If you want to use a specific version of asset "sss", what you
need to do is to modify the source URL, make it pointing to the
specific version of the asset source. eg:
<resource
source='http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/versions/2/source'
type='DRL' />
This is to get version 2 of asset "sss" source.
Cheers,
Jervis
I can only get the package or rule asset's metadata using the urls that you
have mentioned in your post. But i can't fire the rules...please suggest if
i am doing something wrong.
changeset-loans.xml
