Error: RWI 00236 in retrieving Recordset via XIR2 Java SDK Report Engine

Question

Hi,
I use XIR2 Rebean Webi report engine SDK and I am trying to retrieve the recordset of a webi document. I can get all sorts of other properties like SQL, data providers etc but when it comes to retrieving the recordset I get the following error message:
"Exceptio occurred  : com.businessobjects.rebean.wi.CommunicationException: The W
eb Intelligence server could not be reached. Contact your Business Objects admin
istrator. (Error: RWI 00236)"
I first instantiate the ISessionMgr then I get the enterpriseSession by logging in
Then I get the Infostore, and then I prepare my string for the webi doc to get the Infoobjects
String queryStr
// set queryStr  to your webi document
String queryStr = "SELECT * FROM CI_INFOOBJECTS WHERE SI_KIND='" + CeKind.WEBI + "' AND  SI_INSTANCE=0 AND SI_NAME='" + "MyWebiDoc" + "'";
IInfoObjects boInfoObjects = (IInfoObjects) boInfoStore.query(queryStr);
IInfoObject infoObject = (IInfoObject) boInfoObjects.get(0);
ReportEngines boReportEngines = (ReportEngines) enterpriseSession.getService("ReportEngines");
ReportEngine boReportEngine = boReportEngines.getService(ReportEngines.ReportEngineType.WI_REPORT_ENGINE);
DocumentInstance boDocumentInstance = boReportEngine.openDocument(infoObject.getID());
DataProvider dp = null;
                               dp = boDocumentInstance.getDataProviders().getItem(0);
dp.runQuery();                         //SO FAR SO GOOD
Recordset rs = null;
                   rs = dp.getResult(0); //THIS IS WHERE THE PROBLEM OCCURS
It compiles fine and runs fine up until the point while I try to retrieve the recordset
__>
Exceptio occurred  : com.businessobjects.rebean.wi.CommunicationException: The W
eb Intelligence server could not be reached. Contact your Business Objects admin
istrator. (Error: RWI 00236)
The query only retrieves 5 rows so I would tend to rule out that the problem is due to the size of the recordset.
Am I missing something?
Any idea would be very much appreciated.
Thanks in advance
Fabio

Answer 1

I know that "Recordset"  is an interface therefore cannot be directly instantiated.
With this in mind, would the following make sense in Java?
Recordset rs = null;
                   rs = dp.getResult(0);
(dp is a Dataprovider data type)
I checked the object model: the Dataprovider class has got the method
"getResult(in flowIndex: int): Recordset"
so it looks like it can instantiate the Recordset interface.For a simple data provider I believe the index integer input parameter is 0.
(1 would return array out of bound).
I was also thinking of the QueryString I used
String queryStr = "SELECT * FROM CI_INFOOBJECTS WHERE SI_KIND='" + CeKind.WEBI + "' AND SI_INSTANCE=0 AND SI_NAME='" + "MyWebiDoc" + "'";
I would have thought it is fine since I can get other properites of the dataprovider but could there be something not right in the query string as far as the recordset is concerned? Any other ideas?
Thanks in advance.
