<pre>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?</pre>

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:<div class="im"><br>
<br>
<change-set xmlns='<a href="http://drools.org/drools-5.0/change-set" target="_blank">http://drools.org/drools-5.0/change-set</a>'<br>
xmlns:xs='<a href="http://www.w3.org/2001/XMLSchema-instance" target="_blank">http://www.w3.org/2001/XMLSchema-instance</a>'<br>
xs:schemaLocation='<a href="http://drools.org/drools-5.0/change-set" target="_blank">http://drools.org/drools-5.0/change-set</a>

><br>
<add><br></div>
<resource
source='<a href="http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/source" target="_blank">http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/source</a>'
type='DRL' /><br>
</add><br>
</change-set><br>
<br>
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:<br>
<br>
<resource
source='<a href="http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/" target="_blank">http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/</a><a>versions/2/source</a>' type='DRL' /><br>
<br>
This is to get version 2 of asset "sss" source.<br>
<br>
<br>
Cheers,<br>
