How to dynamically reorder subreports?

[prosvet]

Sorry if the a similar question was already answered, but I have not found the answer.

I have main report with many subreports that should be reordered at print time according to user preferences.

What is missing between ellipses (cf. code), are lines that would allow me to access subreports and whether change their source path, or move inside reportSource before compilation.

Thanks in advance

 Finally, I have managed to do what I want. In case if someone later has the same problem, here's the code (just to give an idea):

Code:

String                  sourceLocation = "main_report_location"JasperDesign            reportSource   = JRXmlLoader.load(sourceLocation);JRDesignSubreport subReportDesign = null;JRExpression jrExpression = null;JRElement[] jrElements = ((JRDesignBand) reportSource.getDetailSection().getBands()[0]).getElements();for (JRElement jrElement : jrElements) {	if (jrElement instanceof JRDesignSubreport) {		subReportDesign = (JRDesignSubreport) jrElement;		jrExpression = subReportDesign.getExpression();		[...handle expression contents here...]		subReportDesign.setExpression();	}}ByteArrayOutputStream   reportOutStream   = new ByteArrayOutputStream();JasperCompileManager.compileReportToStream(reportSource, reportOutStream);returnStream = new ByteArrayInputStream(reportOutStream.toByteArray());
