From source file:gov.nih.nci.cadsr.cadsrpasswordchange.core.CommonUtil.java

public static String toString(Throwable theException) {
    // Create a StringWriter and a PrintWriter both of these object
    // will be used to convert the data in the stack trace to a string.
    ////from  ww  w.  ja v a 2 s.  c  om
    StringWriter sw = new StringWriter();
    PrintWriter pw = new PrintWriter(sw);

    //
    // Instead of writting the stack trace in the console we write it
    // to the PrintWriter, to get the stack trace message we then call
    // the toString() method of StringWriter.
    //
    theException.printStackTrace(pw);

    return sw.toString();
