我在NetBeans 7.3 IDE上开发了JAVA的会计软件。
我使用Jasper Report（iReport）在我的应用程序中生成报告。我需要获取我填充到JTable的特定数据，并仅将这些数据提供给Jasper Report。因此，我使用JRTableModelDataSource生成有关Jasper报告的数据。
尽管如此，我失败了，这意味着，当我点击“显示报告”时button tt不显示任何内容，它在NetBeans IDE Log窗口中显示错误，

我使用以下代码填充jTable。
private void GetGLData(){
try
{
con = ConnectionManagerACCDAT.getConnection();
stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
rs = stmt.executeQuery("SELECT * FROM gl_bt_lst ORDER BY BT_NO ASC" );
DefaultTableModel dtm = (DefaultTableModel) tblJournalBatchList.getModel();
Object[] values = new Object[5];
while (rs.next()) {
values = new Object[5];
values[0] = rs.getString("BT_NO");
values[1] = rs.getString("DT");
values[2] = rs.getString("DSCRP");
values[3] = rs.getString("RD_2_PST");
values[4] = rs.getString("PSTTD");
dtm.addRow(values);
}
// Close the connection after use
rs.close();
stmt.close();
con.close();
}
catch (Exception e)
{
JOptionPane.showMessageDialog(null, e, "Journal Batch List.", JOptionPane.ERROR_MESSAGE);
}
}
我使用以下代码生成报告。
private void btnNewActionPerformed(java.awt.event.ActionEvent evt) {
try
{
String ReportSource = "D:/Reports/Test.jrxml";
if (new File(ReportSource).exists() == false)
{
JOptionPane.showMessageDialog(null,"Please go to setting and Choose report Source");
return;
}
JasperReport jasperReport = JasperCompileManager.compileReport(ReportSource);
Map params = new HashMap();
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,
params, new JRTableModelDataSource(tblJournalBatchList.getModel()));
JasperViewer.viewReport(jasperPrint, false);
}
catch (Exception e)
{
JOptionPane.showMessageDialog(null,e,"reports Error ",JOptionPane.ERROR_MESSAGE);
}
// TODO add your handling code here:
}
伙计们，我做错了什么。顺便说一句，我已将相关的库导入NetBeans，将已使用的字段名称导入为COLUMN_1，COLUMN_2 ...等，以将报告链接到jTable列。
