achei
esse codigo aqui no forum, porem mesmo assim não deu certo…

[code]public void DisplayReport() {
Connection conn = null;
try {
Class.forName(“net.sourceforge.jtds.jdbc.Driver”).newInstance();
String reportname = “C:/Users/Bruno/Desktop/EPI/EPI/Relatorios/EstoqueGeral.jasper”;
InputStream fis = this.getClass().getClassLoader().getResourceAsStream(reportname);
conn = DriverManager.getConnection(“jdbc:jtds:sqlserver://server-protheus:1433/EPI”, “bruno”, “bruno”);
HashMap map = new HashMap();
JasperPrint print = JasperFillManager.fillReport(fis, map, conn);
JasperViewer jv = new JasperViewer(print, false); // false Needed not to close parent frame
jv.setVisible(true);
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if (conn != null) {
try {
conn.close();
} catch (Exception ex) {
System.err.println(ex);
}
}
}
}
