      Hi all,

       

      I am trying to unit test a Guided Decision Table. I have plenty of unti tests successfully testing rules, human tasks etc.. however decision tables are causing me trouble. I have created my decision table using the guvnor interface and its stored in the repo. I then pull this file into JBDS and open the .gdst file which simply shows a structured XML file (beginning with <decision-table52>?) , which I guessed was a xml drl format and would be parsed into drl at runtime. However I am having trouble defining the resource type, and I cant find any documentation to help me!

       

      I have tried defining the resource type like so:

       

      kbuilder.add(ResourceFactory.newClassPathResource("testDecisionTable.gdst"),ResourceType.DTABLE);

       

      however when I insert this into my session:

      StatefulKnowledgeSession ksession = createKnowledgeSession(getKbase());

       

      this throws an error on my stacktrace at

      orgs.drools.decisiontable.parser.xls.ExcelParser.parseFile

       

      obviously it's seeing the xml format and thinks its a excel file.

       

      I have also tried using resource type XDRL, considering decision tables are essentially a drl file with a gui & its in xml format:

       

      kbuilder.add(ResourceFactory.newClassPathResource("testDecisionTable.gdst"),ResourceType.XDRL);

       

      I thought this would parse the xml into drl and then I can use tyhe decision table as a rules file! However this throws an error:

       

       

      (null: 1, 19): cvc-elt.1: Cannot find the declaration of element 'decision-table52'.

       

      i.e. there is no schema defined for the file!

       

      Could some1 provide me with some assitance to get these working or some examples of decision tables being used in a junit test would also be great. As I said I ha vent managed to find anything in the documentation, so I'v either overlooked something (probably) or its not in their!

       

      Thanks for any help!
