Wrong forum :). If you want to invoke GUVNOR REST Services using java, I would recommend you to use Apache Abdera. If you want to see some examples, you can take a look at Guvnor's tests (specially those using Abdera :P): - https://github.com/droolsjbpm/guvnor/blob/master/guvnor-webapp-drools/src... - https://github.com/droolsjbpm/guvnor/blob/master/guvnor-webapp-drools/src... If you want to use Grails, then I don't know :) But in the worst case, invoking REST can be achieve by some simple steps in any platform: - Create a HTTP Request pointing to the REST method you want (read Guvnor's manual to see all the different URLs you have) - Invoke the Request - Read the Response - Parse the Response Of course is much more helpful to have a library that already do all these steps for you :) Best Regards, XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Esteban Aliverti - Developer @ http://www.plugtree.com - Blog @ http://ilesteban.wordpress.com On Wed, Jan 11, 2012 at 7:46 PM, kavita <kavithasethu(a)gmail.com&gt; wrote:
