public DebugUtil()

Method Detail

init

protected void init()

setKeepWaiting

public static void setKeepWaiting(boolean keepWaiting)

waitForDebugger

public static void waitForDebugger()

Usage:

Place a call to this method in the earliest possible entry point of your servlet app. It will cause the app to enter into an infinite loop, sleeping until the static var keepWaiting is set to false. The idea is that you attach your debugger to the servlet, then, set a breakpont in this method. When it is hit, you use the debugger to set the keepWaiting class var to false.

printTree

public static String printTree(UIComponent root)

Parameters:

root - the root component

Returns:

the output of printTree() as a String. Useful when used with a Logger. For example: logger.log(DebugUtil.printTree(root));

printTree

public static void printTree(UIComponent root,
                             PrintStream out)

Output of printTree() to a PrintStream. Usage: DebugUtil.printTree(root, System.out);

Parameters:

root - the root component

out - the PrintStream to write to
