IReportAppFactory openDocument() call fails in Eclipse

My webapp fails in Eclipse (but NOT when I run it on the server) at the following line 190:

189:                     java.util.Locale locUS = java.util.Locale.US;

190:                     ReportClientDocument rcd = rptAppFactory.openDocument(boInfoObject,0,locUS);

191:                     rcd.getDataDefController().getParameterFieldController().setCurrentValue("", "PayeeID", payeeID);

192:                     rcd.getDataDefController().getParameterFieldController().setCurrentValue("", "ReportName", rptName);

The error stack trace and root cause info is as follows. Any ideas?:
