Free download generator report for java

Thanks,

Maybe you could help me: ( I asked ther to tis question)

I was download iReport & JasperForge.

My goal now is to print all names in a report from java.

What I need for this?

I tried to write this code, but I don't understand why all the examples used whit jasper file, or jrxml file.

I have to create this file?

I just coppy past a few examples and tried to understood them...

Thank you :)

public class laporan {

public laporan() {

}

public void geraRelatorio() throws JRException, Exception, SQLException {

// design

JasperDesign design = JRXmlLoader.load("hello.jrxml");

// report

JasperReport report = JasperCompileManager.compileReport(design); // THIS

// LINE

// CRASH

// request

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

Connection conn = DriverManager

.getConnection(

"jdbc:sqlserver://matarotsrv:1433;databaseName=qm6",

"sa", "sa");

Statement stm = conn.createStatement();

String query = "SELECT contacts.first_name FROM contacts";

Statement stmt = conn.createStatement();

ResultSet rs = stmt.executeQuery(query);

// JRdataSource

JRDataSource dataSource = new JRResultSetDataSource(rs);

Map params = new HashMap();

// print

JasperPrint print = JasperFillManager.fillReport(report, params,

dataSource);

// exports

JasperExportManager.exportReportToHtmlFile(print, "hello.html");

}

public static void main(String[] args) throws JRException, SQLException,

Exception {

laporan report = new laporan();

report.geraRelatorio();

}

}
