Passing an Array to iReport

[Steve Dyke]

I have an array I need to pass to iReport. I am using JSP to call the report as such:

try{
			if(session.getAttribute("localServer").equals("true")){
				templatefilePath = "//gvas400/home/ResourceManagement/Templates/MainScheduleMatrixReportV4.jasper";
				pdffilePath = "//gvas400/home/ResourceManagement/Docs/MainScheduleMatrix/" + p1 + ".pdf";
									
			}
			else{
				templatefilePath = "/home/ResourceManagement/Templates/MainScheduleMatrixReportV4.jasper";
				pdffilePath = "/home/ResourceManagement/Docs/MainScheduleMatrix/" + p1 + ".pdf";
				
			}		
						    		
				HashMap params = new HashMap();
				params.put("reportArray", msrConn.getMainscheduleArray());
													
				JasperReport aReport = (JasperReport) JRLoader.loadObject(templatefilePath);
				
				JasperPrint aPrint = JasperFillManager.fillReport(aReport, params, gConn.getAs400Conn());
				
				JasperExportManager.exportReportToPdfFile(aPrint, pdffilePath);
								
				jReturnString = "{errorString: 'NoError', filePath: '" + pdffilePath + "'}";
								
		}
		catch(Exception jre){
			System.out.println(jre);
			jReturnString  = "{errorString: Error}";
			
			
				
		}

The parameter on the iReport is "reportArray", Parameter Class Type: java.lang.String[][]

I get the following error in my console when I run this:

[8/31/09 8:07:32:275 CDT] 0000001f SystemOut O net.sf.jasperreports.engine.JRException: Incompatible [[Ljava.lang.String; value assigned to parameter reportArray in the MainScheduleMatrixReportV4 dataset.

hey steve..

even i am facing a similar issue..

i.e i am passing an Integer[] as parameter to the .jrxml file .
in my .jrxml i have
<parameter name="id" class="java.lang.Integer"/>

Now its throwing me exception
"JRException: Incompatible [Ljava.lang.Integer; value assigned to parameter"

i m not sure how to resolve this..
