  1. **Overview** - I have a Java class which has an `ArrayList` that must be printed to the jasperReport as a subreport. - I'm using DynamicJasper library. But If theres a solution without it, I would appreciate it. They offer no free support even for a simple question like this. - The example on this question has been modified so it can be reproduced. However the data is different on the real case. **Problem** The current code Ive come with, prints the subreport in another line. Its ugly. I wanted the subreport to just be a group of columns that are concatenated. To make it clear, here's the current result And What I want is something like this: **Current code** public class Test_subReport { protected static JasperPrint jp; protected static JasperReport jr; protected static Map params = new HashMap(); protected static DynamicReport dr; public static void main(String args[]) throws SQLException, ColumnBuilderException, ClassNotFoundException { Test_subReport t = new Test_subReport(); t.createReport(); } public void createReport() throws SQLException, ColumnBuilderException, ClassNotFoundException { ArrayList<Fruit> createMockDataset = createMockDataset(); Style titleStyle = new Style(); titleStyle.setHorizontalAlign(HorizontalAlign.CENTER); titleStyle.setFont(Font.ARIAL_SMALL_BOLD); Style dataStyle = new Style(); dataStyle.setHorizontalAlign(HorizontalAlign.CENTER); dataStyle.setFont(Font.ARIAL_SMALL); dataStyle.setBlankWhenNull(true); final List items = SortUtils.sortCollection(createMockDataset, Arrays.asList(new String[]{"name", "description"})); FastReportBuilder drb = new FastReportBuilder(); drb.setTemplateFile("templatePortrait.jrxml", true, true, true, true); drb.addColumn("name", "name", String.class.getName(), 30, dataStyle) .addColumn("description", "description", String.class.getName(), 50, dataStyle) .setTitle("Report") .setSubtitle("") .setPrintBackgroundOnOddRows(true) .setUseFullPageWidth(true); drb.addGroups(2); try { drb.addField("evaluations", List.class.getName()); drb.addSubreportInGroupHeader(1, createSubreport("Evaluations")); } catch (Exception ex) { Logger.getLogger(Test_subReport.class.getName()).log(Level.SEVERE, null, ex); } DynamicReport dynamicReport = drb.build(); dynamicReport.setTitleStyle(titleStyle); HashMap parametros = new HashMap(); parametros.put("dataRelatorio", MyTools.getDataPorExtenso()); doReport(dynamicReport, items, parametros); } public void doReport(final DynamicReport _report, final Collection _data, HashMap parametros) { try { JRDataSource beanCollectionDataSource = new JRBeanCollectionDataSource(_data); JasperPrint jasperPrint = DynamicJasperHelper.generateJasperPrint(_report, new ClassicLayoutManager(), beanCollectionDataSource, parametros); JasperViewer.viewReport(jasperPrint); } catch (JRException ex) { ex.printStackTrace(); } } private DynamicReport createHeaderSubreport(String title) throws Exception { FastReportBuilder rb = new FastReportBuilder(); DynamicReport dr = rb .addColumn("id", "id", Integer.class.getName(), 100) .addColumn("score", "score", Double.class.getName(), 50) .setMargins(5, 5, 20, 20) .setUseFullPageWidth(true) .setWhenNoDataNoPages() .setTitle(title) .build(); return dr; } private Subreport createSubreport(String title) throws Exception { SubReportBuilder srb = new SubReportBuilder(); srb.setDynamicReport(createHeaderSubreport(title), new ClassicLayoutManager()) .setStartInNewPage(true) .setDataSource(DJConstants.DATA_SOURCE_ORIGIN_FIELD, DJConstants.DATA_SOURCE_TYPE_COLLECTION, "evaluations"); return srb.build(); } public ArrayList<Fruit> createMockDataset() { ArrayList<Fruit> fruits = new ArrayList<>(); Fruit f1 = new Fruit(); f1.name = "Apple X1"; f1.description = "Yummy yummy apple for the stackoverflow readers 1"; Fruit f2 = new Fruit(); f2.name = "Apple Ag"; f2.description = "Yummy yummy apple for the stackoverflow readers 2"; Fruit f3 = new Fruit(); f3.name = "Apple Mn"; f3.description = "Yummy yummy apple for the stackoverflow readers 3"; Fruit f4 = new Fruit(); f4.name = "Apple O2"; f4.description = "Yummy yummy apple for the stackoverflow readers 4"; //Evaluations for f1 for (int i = 0; i < 4; i++) { Evaluation e = new Evaluation(); e.id = i; e.score = Math.random() * 10; f1.evaluations.add(e); } //evaluations for f4 for (int i = 0; i < 4; i++) { Evaluation e = new Evaluation(); e.id = i; e.score = Math.random() * 10; f4.evaluations.add(e); } fruits.add(f1); fruits.add(f2); fruits.add(f3); fruits.add(f4); return fruits; } public class Fruit { public String name; public String description; public ArrayList<Evaluation> evaluations = new ArrayList<Evaluation>(); public Fruit() { } public Fruit(String name, String description) { this.name = name; this.description = description; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public ArrayList<Evaluation> getEvaluations() { return evaluations; } public void setEvaluations(ArrayList<Evaluation> evaluations) { this.evaluations = evaluations; } } public class Evaluation { public int id; public double score; public Evaluation() { } public Evaluation(int id, double score) { this.id = id; this.score = score; } public int getId() { return id; } public void setId(int id) { this.id = id; } public double getScore() { return score; } public void setScore(double score) { this.score = score; } } }[/code]
