如果我删除其中一个权限,则将显示GUI,但是如果我添加了这两个权限,则GUI将不会显示,并且出现此错误:
线程“ AWT-EventQueue-0”中的异常java.lang.InternalError:当前进程已将其所有系统允许的句柄用于Window Manager对象。
我有一个名为FMenuMasterAgama的jframe来打开FCariMasterAgama,FCariMasterAgama要访问FMenuMasterAgama上的表 这是我在FMenuMasterAgama上的代码:
public class FMenuMasterAgama extends javax.swing.JFrame {
koneksi konek;
Connection conn=null;
Statement stmt= null;
ResultSet rs = null;
FUbahMasterAgama ubahmasteragama;
FMasterAgama tambahagama;
FCariMasterAgama carimaster;
PreparedStatement pst = null;
/**
* Creates new form FMenuMasterNegara
*/
public FMenuMasterAgama() {
initComponents();
konek = new koneksi();
ubahmasteragama = new FUbahMasterAgama();
tambahagama = new FMasterAgama();
carimaster = new FCariMasterAgama();
loadtable();
}
这是我来自FCariMasterAgama的代码:
public class FCariMasterAgama extends javax.swing.JFrame {
koneksi konek;
FMenuMasterAgama menu;
Statement stmt = null;
ResultSet rs = null;
/**
* Creates new form FCariMasterAgama
*/
public FCariMasterAgama() {
initComponents();
konek = new koneksi();
menu = new FMenuMasterAgama();
setDefaultCloseOperation(FCariMasterAgama.DISPOSE_ON_CLOSE);
setLocationRelativeTo(null);
}
