Connection conn=null;
Statement st=null;

JasperReport jr;

JasperPrint jp;
try{
    Class.forName("com.mysql.jdbc.Driver");
    conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/guide","root","");
    st=conn.createStatement();
    rs=st.executeQuery("select * from userentry");

JRResultSetDataSource resultSetDataSource = new JRResultSetDataSource(rs);

//JasperFillManager.fillReportToFile("D:/03033/I_Report files/Guide_Report1.jrxml",new HashMap(),resultSetDataSource);

jr = JasperCompileManager.compileReport("D:/03033/I_Report files/Guide_Report1.jasper");

jp =JasperFillManager.fillReport(jr,new HashMap(),resultSetDataSource);

net.sf.jasperreports.engine.JasperExportManager.exportReportToPdfFile(jp,"D:/Guidereport.pdf");

}catch(Exception e){
out.println(e);
}
