mfg
hier ein auszug vom code:
Code:
model = new DefaultTableModel();
theTab =new JTable();
...
theTab.setModel(model);
model.addTableModelListener(this);
model.setRowCount(0);
model.addcolumn("spalte1"); -> hier taucht dann der fehler auf, und die Tabelle wird nicht aufgebaut!

Bis auf den Schreibfehler...
wäre legitim.
...will mir erst mal nichts auffallen.redman hat gesagt.:
Code:
model.addColumn("Spalte1");

hmm kanns sein dass der fehler nicht bei dir im programm auftritt sondern im DefaultTableModel? guck mal in den Sacktrace.. ich glaub das hatten wir schonmal ???:L
btw: das gehört wohl eher in Swing & AWT

stacktrace ist das ding was die konsole bei nem runtime error ausspuckt. dat zeigt dir die rückverfolgung vonner exception an. meistens sind nur die höchstens die ersten 4-5 elemente wirklich interessant.
achja: wa shast du denn beim 2. prog anders gemacht?
