Hello people..

 

I create a Class, but this not inicialize the report. Look the code:

 

 

Code:

public void init() 
{ 
String sFileName = "http://192.168.200.3:8080/jasper/reports/WebappReport.jasper"; 
if (sFileName != null) 
{ 
try 
{ 
Class.forName("org.gjt.mm.mysql.Driver"«»); 
Connection con = DriverManager.getConnection("jdbc:mysql://192.168.200.3/NewRIPilotoR1SP", "siscart", "bluelau"«»); 
HashMap parametros = new HashMap();  
String sql_cons = "SELECT * FROM reg_cab WHERE protocolo = 130756"; 
parametros.put("sql", sql_cons);  
 
 
jasperReport = (JasperReport)JRLoader.loadObject(new URL(getCodeBase(), sFileName)); 
jasperPrint = JasperManager.fillReport(jasperReport, parametros, con); 
//jasperPrint = JasperFillManager.fillReport(jasperReport, parametros, con); 
 
JasperViewer.viewReport(jasperPrint); 
} 
catch (Exception e) 
{ 
StringWriter swriter = new StringWriter(); 
PrintWriter pwriter = new PrintWriter(swriter); 
e.printStackTrace(pwriter); 
JOptionPane.showMessageDialog(this, swriter.toString()); 
} 
} 
else 
{ 
JOptionPane.showMessageDialog(this, "o caminho nã¯foi especificado"«»);  
} 
}
