Hi,

How retrive sub report name  form an main .jasper file ?

I have tried with succes, but it's not very good for me ?

Who have an idea Thanks

String fileName="c:\CustomersReport.jrxml";
                 JasperCompileManager.compileReportToFile(fileName);
                 JasperReport  jasperReport = JasperCompileManager.compileReport(fileName);
            
             JRBand jb = jasperReport.getDetail();
          // jb children Expression
          java.util.List jl=jb.getChildren();
             JRBaseSubreport  jsr=(JRBaseSubreport)jl.get(3);
             JRExpression jre=jsr.getExpression();
             JRExpressionChunk[] jch=jre.getChunks();
             String fichierjasper=jch[0].getText();
