Re: [cinjug-users] printStackTrace prints nothing

you need to flush the PrintWriter before calling toString()

also remember to close it.

My code has logic like

java.io.StringWriter writer = new java.io.StringWriter();
e.printStackTrace(new java.io.PrintWriter(writer));
String stackTraceString = writer.toString();

buf.append(stackTraceString);

LOG.error(buf);

But in my log file I only see

java.lang.NullPointerException

There is no stack trace after it and also no print out like <trace available>>

How come the stack trace of java.lang.NullPointerException has not been
printed out?

Thanks!
