How do I initialize the IContext interface variable in RTC 3.0.1.3 to make the following code work for a precondition? I'm unable to declare in in the run method because the run methods is an implementation of the IOperationAdvisor interface.

Thanks!


        //Use HttpConnectorParameters to define variables for Http Lookup
        HttpConnectorParameters params = new HttpConnectorParameters();
        params.url = "URL";
        params.xpath = "//srnumber";
        params.columnXpaths = new String[] {"./nextnumber/@data"};
        params.columnIds = new String[]{"nextnumber"};
       
        IContext context=..................
        IDataConnector connector = context.getDataConnector("HttpConnector");
        IHttpConnector conParams = (IHttpConnector) connector;
       
        try{
           
            IResponse connectorParams = connector.get(params);
           
            String results[];           
            while (connectorParams.hasNext()){
                IResponseEntry entry = connectorParams.next();
                String nextnumber = entry.getById("nextnumber");
            }
        }
        catch(ConnectorException c){
            System.out.println("Unable to connect to webservice");
        }
