1. How do I display the System.out console in a view in my Eclipse RCP application?

 

The answer has two parts. To start, you can redirect console output to an arbitrary PrintStream usingSystem.setOut(somePrintStream);. The second part is that you need a useful PrintStream to write on.

 

import org.eclipse.swt.SWT; import org.eclipse.swt.events.DisposeEvent; import org.eclipse.swt.events.DisposeListener; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Text; import org.eclipse.ui.part.ViewPart; public class LightweightConsoleView extends ViewPart { private Text text; public void createPartControl(Composite parent) { text = new Text(parent, SWT.READ_ONLY | SWT.MULTI); OutputStream out = new OutputStream() { @Override public void write(int b) throws IOException { if (text.isDisposed()) return; text.append(String.valueOf((char) b)); } }; final PrintStream oldOut = System.out; System.setOut(new PrintStream(out)); text.addDisposeListener(new DisposeListener() { public void widgetDisposed(DisposeEvent e) { System.setOut(oldOut); } }); } public void setFocus() { text.setFocus(); } } 

for multithread you may do this:

OutputStream out = new OutputStream() { private StringBuffer buffer = new StringBuffer(); private final Object obj = new Object(); @Override public void write(final int b) throws IOException { synchronized (obj) { if (text.isDisposed()) return; buffer.append((char) b); } } @Override public void write(byte[] b, int off, int len) throws IOException { super.write(b, off, len); flush(); } @Override public void flush() throws IOException { synchronized (obj) { final String newText = buffer.toString(); text.append(newText); buffer = new StringBuffer(); } } }; 

to show ConsoleView use this :

 

 

layout.addView(IConsoleConstants.ID_CONSOLE_VIEW, IPageLayout.BOTTOM, .5f, layout.getEditorArea());  

or another way like this:

Add these variables to your plugin class: 

private MessageConsole myConsole; 
private MessageConsoleStream msgStream;

Then add this to the plugin constructor: 

myConsole = new MessageConsole("My Console", null); 
ConsolePlugin.getDefault().getConsoleManager().addConsoles(new IConsole[] { myConsole }); 
msgStream = myConsole.newMessageStream(); 

Then add these methods to your plugin class: 

public MessageConsoleStream getMessageConsoleStream() { 
return msgStream; 
} 

public MessageConsole getMessageConsole() { 
return myConsole; 
} 
Then to write to the console in a class do this: 

private MessageConsoleStream msgStream = ServersPlugin.getDefault().getMessageConsoleStream(); as a variable. 

msgStream.println("Refreshing from Server 1"); //to print to the console.
