>>  Hi
>>
>> I am using Drool-5.2.0 final, Guvnor 5.2.0 final and
>> designer-2.0-jboss.war in Drools-Guvnor.
>> In Designer, I created simple process with start node, one task node, and
>> end node. I made Task type of task node as "Script". I entered simple java
>> code as System.out.print("Hi "); in the Script option of the task node.
>> Sorry I dont know API's used for loading this process in Eclipse.
>> So can any one tell me the API's used for loading this process in
>> Eclipse.?
