Java Code Snippet: Redirect System.out into a string

For a simple test application / prototype I just wanted to just dump everything from System.out into a String, which I can output somewhere e.g. in a JSP file so that I see what’s going on. And yes, I didn’t want to setup a Logging framework for this…I want a String. Here it is:

public static void main(String[] args) {

OutputStream out = new ByteArrayOutputStream();

System.setOut(new PrintStream(out));

System.out.println(“Test”);

String sysout_content = out.toString();

System.out.println();

}
