There is an easy an elegant way to convert or store an exception stack trace to a string variable. The following method takes an exception object as a parameter and returns the string representation of the stack trace.

public String getStackTrace(Exception ex) {
        java.io.StringWriter out = new java.io.StringWriter();
        ex.printStackTrace(new java.io.PrintWriter(out));
        String stackTrace = out.toString();
 
        return stackTrace;
    }
