Answer 1

It is not the Parameter Issue. Its file Path issue. You need to load the jrxml file in the form of stream other wise on server due to the file path resolving in Springboot some time create complex paths which usually not found or people make mistakes defining path. You have to follow some steps.

1. Create folder in Resources directory of you project

2. Place your jrxml there

3. Load your jrxml file as Stream

InputStream stream=getClass().getResourceAsStream("/yourdir/yourfile.jrxml");

4. Compile the Stream into jasperReport Obeject

   JasperReport subReportJasperCompileManager.compileReport(stream);

5. Now Pass it in Param List with the same name in your Parent Report

   parameters.put("sub_report_setting", subJasperReportSetting);

Here are the 3,4 and 5th steps.

InputStream stream=getClass().getResourceAsStream("/yourdir/yourfile.jrxml");
JasperReport subReportJasperCompileManager.compileReport(stream);
parameters.put("sub_report", subJasperReportSetting);
