Swing text components fail to paste large text data from clipboard: java.io.IOException: Owner failed to convert data

Question

I am working with a JTextArea directly and via JTextComponent interface attempting to paste text data from outside the swing-based app (notepad) into the app.

Using two different methods (shown below) I seem to be getting the same result for large amounts of text data. It works fine as long as I stick to small amounts (<25k) but pasting in a white-list of domains around 1.5MB seems to cause the IOException. I have seen a number of articles for various apps around the net referring to it being a bug in the 1.6 JVM. I'm currently using jdk1.7.0_25 and I'm wondering if anyone knows a resolution or workaround???

I'm also open to the possibility that I'm going about this thing the wrong way entirely...

code:

 @Override public void actionPerformed(ActionEvent ae) { String cmd = ae.getActionCommand(); log.debug("Running {}",cmd); if (cmd.equals("copy")){ this.component.copy(); } else if (cmd.equals("paste")){ // Simple paste -- but large data doesnt paste this.component.paste(); } else { log.warn("No handler for {}", cmd); } } 

also tried:

 Clipboard c = Toolkit.getDefaultToolkit().getSystemClipboard(); Transferable t = c.getContents(this); if (t == null) return; try { component.setText((String) t.getTransferData(DataFlavor.stringFlavor)); } catch (Exception e){ e.printStackTrace(); } 

Exception:

== Update ==

Additional testing seems to indicate that this only occurs on Linux operating systems (which I use for dev) but it seems to operate on windows (which I don't use).

Answer 1

Don't know if it will work any better on large data but you can try using the default Action from the DefaultEditorKit to do the copy:

JButton paste = new JButton( new DefaultEditorKit.PasteAction() );

The Action can also be added to a JMenuItem.
