The fetch method is only called once per data set row. Generally you
set up an iterator in the open and use the iterator in the fetch. In
your case is userParams one row of data or multiple rows?

Move this to the open:
userParams = reportParams.getReportValues("Java");
Then in the fetch use:
if (count < userParams.size() )
{
var rowdata = userParams.get(count);
importPackage( Packages.java.io );
out = new PrintWriter( new FileWriter( "c:/temp/fetchevents.txt", true ) );
out.println( "row data " + rowdata);
out.println( "firstCol " + rowdata.getReportStart());
out.close();
var rtnString = rowdata.getReportStart();
dataSetRow["Start Time:"] = rtnString;
var rtnStrng = rowdata.getReportEndTime
dataSetRow["End Time:"] = rtnString;
count++;
return true;
}
return false;
Then take a look at the text file that is generated.

What do you get when you change:
userParams = reportParams.getReportValues("Java");
to
userParams = reportParams.getReportValues("Java", "Java", "Java");
