Hi everyone,
I am a newcomer here and i'm looking for a tutorial of how to integrate jasper reports in scout.
I use the eclipse neon and i don't have the "scout explorer view" only the "project explorer"
the integration tutorial: https://wiki.eclipse.org/Scout/Tutorial/4.0/JasperReports_Integration
show how to do it but using "scout explorer view" so i am a little lost, someone knows how to do it on eclipse neon on "project explorer" ?

Jasper integration:
The integration is basically the same as in any other java/maven environment (lots of tuturials around).

pom dependencies
Add the following dependencies to your project. Usually in the server parts pom file.

		<dependency>
			<groupId>net.sf.jasperreports</groupId>
			<artifactId>jasperreports</artifactId>
			<version>6.4.0</version>
			<exclusions>
				<exclusion>
					<groupId>javax.xml.stream</groupId>
					<artifactId>stax-api</artifactId>
					<!-- <version>1.0-2</version> -->
				</exclusion>
				<exclusion>
					<groupId>org.bouncycastle</groupId>
					<artifactId>bcmail-jdk14</artifactId>
				</exclusion>
				<exclusion>
					<groupId>org.bouncycastle</groupId>
					<artifactId>bcprov-jdk14</artifactId>
				</exclusion>
			</exclusions>
		</dependency>
		<dependency>
			<groupId>net.sf.jasperreports</groupId>
			<artifactId>jasperreports-fonts</artifactId>
			<version>6.0.0</version>
		</dependency>

Report definition
Create a report definition (*.jrxml) e.g. using the report designer and put it into the <your module>/src/main/resources/jasper.

Create the report
Could look like:

    InputStream billStream = getClass().getResourceAsStream("/jasper/bill.jrxml");

    try {
      JasperReport jasperBillReport = JasperCompileManager.compileReport(billStream);
      Map<String, Object> parameters = new HashMap<>();
	  // put parameters here
      JRBeanCollectionDataSource connection = new JRBeanCollectionDataSource(CollectionUtility.arrayList(yourBean));
      JasperPrint print = JasperFillManager.fillReport(jasperBillReport, parameters, connection);
      return JasperExportManager.exportReportToPdf(print);
    }
    catch (JRException e) {
      throw BEANS.get(PlatformExceptionTranslator.class).translate(e);
    }

A sample implementation is available under Github Docbox.

Hi Andreas,
in your example you create a Jasper Reports in PDF

return JasperExportManager.exportReportToPdf(print);

Is it possible generate a word document? If so, how?

You have examples or suggestions on how to proceed

Thanks
Marco

Hello Andreas,
Thank you for the helpful tips including the sample implementation.
I changed many things in my implementation but i successfully generated a jasper report and save it on database using a bytea field on postgres, i am having only a problem to retreive it and show on the browser

this the File field on my TablePage that i am using to retreive the content(pdf file)

public class FileColumn extends AbstractColumn<byte[]> {
			
			@Override
			protected String getConfiguredHeaderText() {
				return TEXTS.get("File");
			}
			
			@Override
			protected boolean getConfiguredHtmlEnabled() {
				return true;
			}

			@Override
			protected int getConfiguredWidth() {
				return 100;
			}

			@Override
			protected boolean getConfiguredVisible() {
				return true;
			}

			@Override
		      protected void execDecorateCell(Cell cell, ITableRow row) {
		     		        
		        StringBuilder linkBuilder = new StringBuilder();
		        linkBuilder.append(getFileColumn ().getValue(row));
		        String encodedHtml = HTML.link(linkBuilder, TEXTS.get("Open")).addAttribute("target", "_blank").toHtml();
		        cell.setHtmlEnabled(true);
		        cell.setText(encodedHtml);
		      }
		}

Any ideia of how can i do it?

Thank you, Marco.
