Retrieve the decision table in readable format from ODM Decision Center using Java code/API

Question

I need to extract the contents of a decision table in a readable/tabular format from the IBM ODM Decision Center Business Console using Java and ODM APIs provided.

This has to be an automated process and hence I cannot use the existing Import/Export feature provided by ODM.

Does anyone have any sample code or have implemented such a requirement?

Version: ODM 8.10.1

Answer 1

Step 1: Query the decision center for the decision table (see here for instructions)

Step 2:

                if (rule.getType().equals("brm.DecisionTable")) {
                        IlrDecisionTable dTable = (IlrDecisionTable) rule;
                        IlrDTController controller = IlrSessionHelper.getDTController(session, dTable, new Locale(dTable.getLocale()));
                        String tableHtml = IlrDTHelper.getHTMLTable(controller, false, false);//getHTMLTable(IlrDTController controller, boolean showEmptyRow, boolean includeCSS)
                        ...
                    }

Answer 2

if you synchronise your Rule Designer rules with Decision Center, you can use REST API to extract your Decision Table as an excel file from Decision Center.
